 Adding a system call usually involves:
 
-  1. Add entries to SYSCALLS.TXT.
+  1. Add an entry (or entries, in some cases) to SYSCALLS.TXT.
      See SYSCALLS.TXT itself for documentation on the format.
-  2. Add constants (and perhaps types) to the appropriate header file.
+     See also the notes below for how to deal with tricky cases like `off_t`.
+  2. Find the right header file to work in by looking up your system call
+     on [man7.org](https://man7.org/linux/man-pages/dir_section_2.html).
+     (If there's no header file given, see the points above about whether we
+     should really be adding this or not!)
+  3. Add constants (and perhaps types) to the appropriate header file.
      Note that you should check to see whether the constants are already in
      kernel uapi header files, in which case you just need to make sure that
-     the appropriate POSIX header file in libc/include/ includes the
-     relevant file or files.
-  3. Add function declarations to the appropriate header file. Don't forget
-     to include the appropriate `__INTRODUCED_IN()`. If you need to create a new
-     header file, libc/include/sys/sysinfo.h is a good short example to copy and
-     paste from.
-  4. Add basic documentation to the header file. libc/include/sys/sysinfo.h is a
-     good short example that shows the expected style. Most of the detail
-     should actually be left to the man7.org page, with only a brief
-     one-sentence explanation in our documentation. Alway include the return
-     value/error reporting details. Explicitly say which version of Android the
-     function was added to. Explicitly call out any Android-specific
-     changes/additions/limitations because they won't be on the man7.org page.
-  5. Add the function name to the correct section in libc/libc.map.txt.
-  6. Add a basic test. Don't try to test everything; concentrate on just testing
+     the appropriate header file in libc/include/ `#include`s the relevant
+     `linux/` file or files.
+  4. Add function declarations to the appropriate header file. Don't forget
+     to include the appropriate `__INTRODUCED_IN()`, with the right API level
+     for the first release your system call wrapper will be in. See
+     libc/include/android/api_level.h for the API levels.
+     If the header file doesn't exist, copy all of libc/include/sys/sysinfo.h
+     into your new file --- it's a good short example to start from.
+
+     Note also our style for naming arguments: always use two leading
+     underscores (so developers are free to use any of the unadorned names as
+     macros without breaking things), avoid abbreviations, and ideally try to
+     use the same name as an existing system call (to reduce the amount of
+     English vocabulary required by people who just want to use the function
+     signatures). If there's a similar function already in the C library,
+     check what names it's used. Finally, prefer the `void*` orthography we
+     use over the `void *` you'll see on man7.org.)
+  5. Add basic documentation to the header file. Again, the existing
+     libc/include/sys/sysinfo.h is a good short example that shows the
+     expected style.
+
+     Most of the detail should actually be left to the man7.org page, with
+     only a brief one-sentence explanation (usually based on the description
+     in the NAME section of the man page) in our documentation. Always
+     include the return value/error reporting details (you can find out
+     what the system call returns from the RETURN VALUE of the man page),
+     but try to match the wording and style wording from _our_ existing
+     documentation; we're trying to minimize the amount of English readers
+     need to understand by using the exact same wording where possible).
+     Explicitly say which version of Android the function was added to in
+     the documentation because the documentation generation tool doesn't yet
+     understand `__INTRODUCED_IN()`.
+
+     Explicitly call out any Android-specific changes/additions/limitations
+     because they won't be on the man7.org page.
+  6. Add the function name to the correct section in libc/libc.map.txt; it'll
+     be near the end of the file. You may need to add a new section if you're
+     the first to add a system call to this version of Android.
+  7. Add a basic test. Don't try to test everything; concentrate on just testing
      the code that's actually in *bionic*, not all the functionality that's
      implemented in the kernel. For simple syscalls, that's just the
      auto-generated argument and return value marshalling.
 
+     Add a test in the right file in tests/. We have one file per header, so if
+     your system call is exposed in <unistd.h>, for example, your test would go
+     in tests/unistd_test.cpp.
+

+
+# The Anatomy of Clang FORTIFY
+
+## Objective
+
+The intent of this document is to run through the minutiae of how Clang FORTIFY
+actually works in Bionic at the time of writing. Other FORTIFY implementations
+that target Clang should use very similar mechanics. This document exists in part
+because many Clang-specific features serve multiple purposes simultaneously, so
+getting up-to-speed on how things function can be quite difficult.
+
+## Background
+
+FORTIFY is a broad suite of extensions to libc aimed at catching misuses of
+common library functions. Textually, these extensions exist purely in libc, but
+all implementations of FORTIFY rely heavily on C language extensions in order
+to function at all.
+
+Broadly, FORTIFY implementations try to guard against many misuses of C
+standard(-ish) libraries:
+- Buffer overruns in functions where pointers+sizes are passed (e.g., `memcpy`,
+  `poll`), or where sizes exist implicitly (e.g., `strcpy`).
+- Arguments with incorrect values passed to libc functions (e.g.,
+  out-of-bounds bits in `umask`).
+- Missing arguments to functions (e.g., `open()` with `O_CREAT`, but no mode
+  bits).
+
+FORTIFY is traditionally enabled by passing `-D_FORTIFY_SOURCE=N` to your
+compiler. `N==0` disables FORTIFY, whereas `N==1`, `N==2`, and `N==3` enable
+increasingly strict versions of it. In general, FORTIFY doesn't require user
+code changes; that said, some code patterns
+are [incompatible with stricter versions of FORTIFY checking]. This is largely
+because FORTIFY has significant flexibility in what it considers to be an
+"out-of-bounds" access.
+
+FORTIFY implementations use a mix of compiler diagnostics and runtime checks to
+flag and/or mitigate the impacts of the misuses mentioned above.
+
+Further, given FORTIFY's design, the effectiveness of FORTIFY is a function of
+-- among other things -- the optimization level you're compiling your code at.
+Many FORTIFY implementations are implicitly disabled when building with `-O0`,
+since FORTIFY's design for both Clang and GCC relies on optimizations in order
+to provide useful run-time checks. For the purpose of this document, all
+analysis of FORTIFY functions and commentary on builtins assume that code is
+being built with some optimization level > `-O0`.
+
+### A note on GCC
+
+This document talks specifically about Bionic's FORTIFY implementation targeted
+at Clang. While GCC also provides a set of language extensions necessary to
+implement FORTIFY, these tools are different from what Clang offers. This
+divergence is an artifact of Clang and GCC's differing architecture as
+compilers.
+
+Textually, quite a bit can be shared between a FORTIFY implementation for GCC
+and one for Clang (e.g., see [ChromeOS' Glibc patch]), but this kind of sharing
+requires things like macros that expand to unbalanced braces depending on your
+compiler:
+
+```c
+/*
+ * Highly simplified; if you're interested in FORTIFY's actual implementation,
+ * please see the patch linked above.
+ */
+#ifdef __clang__
+# define FORTIFY_PRECONDITIONS
+# define FORTIFY_FUNCTION_END
+#else
+# define FORTIFY_PRECONDITIONS {
+# define FORTIFY_FUNCTION_END }
+#endif
+
+/*
+ * FORTIFY_WARNING_ONLY_IF_SIZE_OF_BUF_LESS_THAN is not defined, due to its
+ * complexity and irrelevance. It turns into a compile-time warning if the
+ * compiler can determine `*buf` has fewer than `size` bytes available.
+ */
+

+FORTIFY_PRECONDITIONS
+  FORTIFY_WARNING_ONLY_IF_SIZE_OF_BUF_LESS_THAN(buf, size, "`buf` is too smol.")

+
+## The Life of a Clang FORTIFY Function
+
+As referenced in the Background section, FORTIFY performs many different checks
+for many functions. This section intends to go through real-world examples of
+FORTIFY functions in Bionic, breaking down how each part of these functions
+work, and how the pieces fit together to provide FORTIFY-like functionality.
+
+While FORTIFY implementations may differ between stdlibs, they broadly follow
+the same patterns when implementing their checks for Clang, and they try to
+make similar promises with respect to FORTIFY compiling to be zero-overhead in
+some cases, etc. Moreover, while this document specifically examines Bionic,
+many stdlibs will operate _very similarly_ to Bionic in their Clang FORTIFY
+implementations.
+
+**In general, when reading the below, be prepared for exceptions, subtlety, and
+corner cases. The individual function breakdowns below try to not offer
+redundant information. Each one focuses on different aspects of FORTIFY.**
+
+### Terminology
+
+Because FORTIFY should be mostly transparent to developers, there are inherent
+naming collisions here: `memcpy(x, y, z)` turns into fundamentally different
+generated code depending on the value of `_FORTIFY_SOURCE`. Further, said
+`memcpy` call with `_FORTIFY_SOURCE` enabled needs to be able to refer to the
+`memcpy` that would have been called, had `_FORTIFY_SOURCE` been disabled.
+Hence, the following convention is followed in the subsections below for all
+prose (namely, multiline code blocks are exempted from this):
+
+- Standard library function names preceded by `__builtin_` refer to the use of
+  the function with `_FORTIFY_SOURCE` disabled.
+- Standard library function names without a prefix refer to the use of the
+  function with `_FORTIFY_SOURCE` enabled.
+
+This convention also applies in `clang`. `__builtin_memcpy` will always call
+`memcpy` as though `_FORTIFY_SOURCE` were disabled.
+
+## Breakdown of `mempcpy`
+
+The [FORTIFY'ed version of `mempcpy`] is a full, featureful example of a
+FORTIFY'ed function from Bionic. From the user's perspective, it supports a few
+things:
+- Producing a compile-time error if the number of bytes to copy trivially
+  exceeds the number of bytes available at the destination pointer.
+- If the `mempcpy` has the potential to write to more bytes than what is
+  available at the destination, a run-time check is inserted to crash the
+  program if more bytes are written than what is allowed.
+- Compiling away to be zero overhead when none of the buffer sizes can be
+  determined at compile-time[^1].
+
+The declaration in Bionic's headers for `__builtin_mempcpy` is:
+```c
+void* mempcpy(void* __dst, const void* __src, size_t __n) __INTRODUCED_IN(23);
+```
+
+Which is annotated with nothing special, except for Bionic's versioner, which
+is Android-specific (and orthogonal to FORTIFY anyway), so it will be ignored.
+
+The [source for `mempcpy`] in Bionic's headers for is:
+```c
+__BIONIC_FORTIFY_INLINE
+void* mempcpy(void* const dst __pass_object_size0, const void* src, size_t copy_amount)
+        __overloadable
+        __clang_error_if(__bos_unevaluated_lt(__bos0(dst), copy_amount),
+                         "'mempcpy' called with size bigger than buffer") {
+#if __BIONIC_FORTIFY_RUNTIME_CHECKS_ENABLED
+    size_t bos_dst = __bos0(dst);
+    if (!__bos_trivially_ge(bos_dst, copy_amount)) {
+        return __builtin___mempcpy_chk(dst, src, copy_amount, bos_dst);
+    }
+#endif
+    return __builtin_mempcpy(dst, src, copy_amount);
+}
+```
+
+Expanding some of the important macros here, this function expands to roughly:
+```c
+static
+__inline__
+__attribute__((no_stack_protector))
+__attribute__((always_inline))
+void* mempcpy(
+        void* const dst __attribute__((pass_object_size(0))),
+        const void* src,
+        size_t copy_amount)
+        __attribute__((overloadable))
+        __attribute__((diagnose_if(
+            __builtin_object_size(dst, 0) != -1 && __builtin_object_size(dst, 0) <= copy_amount),
+            "'mempcpy' called with size bigger than buffer"))) {
+#if __BIONIC_FORTIFY_RUNTIME_CHECKS_ENABLED
+    size_t bos_dst = __builtin_object_size(dst, 0);
+    if (!(__bos_trivially_ge(bos_dst, copy_amount))) {
+        return __builtin___mempcpy_chk(dst, src, copy_amount, bos_dst);
+    }
+#endif
+    return __builtin_mempcpy(dst, src, copy_amount);
+}
+```
+
+So let's walk through this step by step, to see how FORTIFY does what it says on
+the tin here.
+
+[^1]: "Zero overhead" in a way [similar to C++11's `std::unique_ptr`]: this will
+turn into a direct call `__builtin_mempcpy` (or an optimized form thereof) with
+no other surrounding checks at runtime. However, the additional complexity may
+hinder optimizations that are performed before the optimizer can prove that the
+`if (...) { ... }` can be optimized out. Depending on how late this happens,
+the additional complexity may skew inlining costs, hide opportunities for e.g.,
+`memcpy` coalescing, etc etc.
+
+### How does Clang select `mempcpy`?
+
+First, it's critical to notice that `mempcpy` is marked `overloadable`. This
+function is a `static inline __attribute__((always_inline))` overload of
+`__builtin_mempcpy`:
+- `__attribute__((overloadable))` allows us to perform overloading in C.
+- `__attribute__((overloadable))` mangles all calls to functions marked with
+  `__attribute__((overloadable))`.
+- `__attribute__((overloadable))` allows exactly one function signature with a
+  given name to not be marked with `__attribute__((overloadable))`. Calls to
+  this overload will not be mangled.
+
+Second, one might note that this `mempcpy` implementation has the same C-level
+signature as `__builtin_mempcpy`. `pass_object_size` is a Clang attribute that
+is generally needed by FORTIFY, but it carries the side-effect that functions
+may be overloaded simply on the presence (or lack of presence) of
+`pass_object_size` attributes. Given two overloads of a function that only
+differ on the presence of `pass_object_size` attributes, the candidate with
+`pass_object_size` attributes is preferred.
+
+Finally, the prior paragraph gets thrown out if one tries to take the address of
+`mempcpy`. It is impossible to take the address of a function with one or more
+parameters that are annotated with `pass_object_size`. Hence,
+`&__builtin_mempcpy == &mempcpy`. Further, because this is an issue of overload
+resolution, `(&mempcpy)(x, y, z);` is functionally identical to
+`__builtin_mempcpy(x, y, z);`.
+
+All of this accomplishes the following:
+- Direct calls to `mempcpy` should call the FORTIFY-protected `mempcpy`.
+- Indirect calls to `&mempcpy` should call `__builtin_mempcpy`.
+
+### How does Clang offer compile-time diagnostics?
+
+Once one is convinced that the FORTIFY-enabled overload of `mempcpy` will be
+selected for direct calls, Clang's `diagnose_if` and `__builtin_object_size` do
+all of the work from there.
+
+Subtleties here primarily fall out of the discussion in the above section about
+`&__builtin_mempcpy == &mempcpy`:
+```c
+#define _FORTIFY_SOURCE 2
+#include <string.h>
+void example_code() {
+  char buf[4]; // ...Assume sizeof(char) == 1.
+  const char input_buf[] = "Hello, World";
+  mempcpy(buf, input_buf, 4); // Valid, no diagnostic issued.
+
+  mempcpy(buf, input_buf, 5); // Emits a compile-time error since sizeof(buf) < 5.
+  __builtin_mempcpy(buf, input_buf, 5); // No compile-time error.
+  (&mempcpy)(buf, input_buf, 5); // No compile-time error, since __builtin_mempcpy is selected.
+}
+```
+
+Otherwise, the rest of this subsection is dedicated to preliminary discussion
+about `__builtin_object_size`.
+
+Clang's frontend can do one of two things with `__builtin_object_size(p, n)`:
+- Evaluate it as a constant.
+  - This can either mean declaring that the number of bytes at `p` is definitely
+    impossible to know, so the default value is used, or the number of bytes at
+    `p` can be known without optimizations.
+- Declare that the expression cannot form a constant, and lower it to
+  `@llvm.objectsize`, which is discussed in depth later.
+
+In the examples above, since `diagnose_if` is evaluated with context from the
+caller, Clang should be able to trivially determine that `buf` refers to a
+`char` array with 4 elements.
+
+The primary consequence of the above is that diagnostics can only be emitted if
+no optimizations are required to detect a broken code pattern. To be specific,
+clang's constexpr evaluator must be able to determine the logical object that
+any given pointer points to in order to fold `__builtin_object_size` to a
+constant, non-default answer:
+
+```c
+#define _FORTIFY_SOURCE 2
+#include <string.h>
+void example_code() {
+  char buf[4]; // ...Assume sizeof(char) == 1.
+  const char input_buf[] = "Hello, World";
+  mempcpy(buf, input_buf, 4); // Valid, no diagnostic issued.
+  mempcpy(buf, input_buf, 5); // Emits a compile-time error since sizeof(buf) < 5.
+  char *buf_ptr = buf;
+  mempcpy(buf_ptr, input_buf, 5); // No compile-time error; `buf_ptr`'s target can't be determined.
+}
+```
+
+### How does Clang insert run-time checks?
+
+This section expands on the following statement: FORTIFY has zero runtime cost
+in instances where there is no chance of catching a bug at run-time. Otherwise,
+it introduces a tiny additional run-time cost to ensure that functions aren't
+misused.
+
+In prior sections, the following was established:
+- `overloadable` and `pass_object_size` prompt Clang to always select this
+  overload of `mempcpy` over `__builtin_mempcpy` for direct calls.
+- If a call to `mempcpy` was trivially broken, Clang would produce a
+  compile-time error, rather than producing a binary.
+
+Hence, the case we're interested in here is one where Clang's frontend selected
+a FORTIFY'ed function's implementation for a function call, but was unable to
+find anything seriously wrong with said function call. Since the frontend is
+powerless to detect bugs at this point, our focus shifts to the mechanisms that
+LLVM uses to support FORTIFY.
+
+Going back to Bionic's `mempcpy` implementation, we have the following (ignoring
+diagnose_if and assuming run-time checks are enabled):
+```c
+static
+__inline__
+__attribute__((no_stack_protector))
+__attribute__((always_inline))
+void* mempcpy(
+        void* const dst __attribute__((pass_object_size(0))),
+        const void* src,
+        size_t copy_amount)
+        __attribute__((overloadable)) {
+    size_t bos_dst = __builtin_object_size(dst, 0);
+    if (bos_dst != -1 &&
+        !(__builtin_constant_p(copy_amount) && bos_dst >= copy_amount)) {
+        return __builtin___mempcpy_chk(dst, src, copy_amount, bos_dst);
+    }
+    return __builtin_mempcpy(dst, src, copy_amount);
+}
+```
+
+In other words, we have a `static`, `always_inline` function which:
+- If `__builtin_object_size(dst, 0)` cannot be determined (in which case, it
+  returns -1), calls `__builtin_mempcpy`.
+- Otherwise, if `copy_amount` can be folded to a constant, and if
+  `__builtin_object_size(dst, 0) >= copy_amount`, calls `__builtin_mempcpy`.
+- Otherwise, calls `__builtin___mempcpy_chk`.
+
+
+How can this be "zero overhead"? Let's focus on the following part of the
+function:
+
+```c
+    size_t bos_dst = __builtin_object_size(dst, 0);
+    if (bos_dst != -1 &&
+        !(__builtin_constant_p(copy_amount) && bos_dst >= copy_amount)) {
+```
+
+If Clang's frontend cannot determine a value for `__builtin_object_size`, Clang
+lowers it to LLVM's `@llvm.objectsize` intrinsic. The `@llvm.objectsize`
+invocation corresponding to `__builtin_object_size(p, 0)` is guaranteed to
+always fold to a constant value by the time LLVM emits machine code.
+
+Hence, `bos_dst` is guaranteed to be a constant; if it's -1, the above branch
+can be eliminated entirely, since it folds to `if (false && ...)`. Further, the
+RHS of the `&&` in this branch has us call `__builtin_mempcpy` if `copy_amount`
+is a known value less than `bos_dst` (yet another constant value). Therefore,
+the entire condition is always knowable when LLVM is done with LLVM IR-level
+optimizations, so no condition is ever emitted to machine code in practice.
+
+#### Why is "zero overhead" in quotes? Why is `unique_ptr` relevant?
+
+`__builtin_object_size` and `__builtin_constant_p` are forced to be constants
+after most optimizations take place. Until LLVM replaces both of these with
+constants and optimizes them out, we have additional branches and function calls
+in our IR. This can have negative effects, such as distorting inlining costs and
+inhibiting optimizations that are conservative around branches in control-flow.
+
+So FORTIFY is free in these cases _in isolation of any of the code around it_.
+Due to its implementation, it may impact the optimizations that occur on code
+around the literal call to the FORTIFY-hardened libc function.
+
+`unique_ptr` was just the first thing that came to the author's mind for "the
+type should be zero cost with any level of optimization enabled, but edge-cases
+might make it only-mostly-free to use."
+
+### How is checking actually performed?
+
+In cases where checking can be performed (e.g., where we call
+`__builtin___mempcpy_chk(dst, src, copy_amount, bos_dst);`), Bionic provides [an
+implementation for `__mempcpy_chk`]. This is:
+
+```c
+extern "C" void* __mempcpy_chk(void* dst, const void* src, size_t count, size_t dst_len) {
+  __check_count("mempcpy", "count", count);
+  __check_buffer_access("mempcpy", "write into", count, dst_len);
+  return mempcpy(dst, src, count);
+}
+```
+This function itself boils down to a few small branches which abort the program
+if they fail, and a direct call to `__builtin_mempcpy`.
+
+### Wrapping up
+
+In the above breakdown, it was shown how Clang and Bionic work together to:
+- represent FORTIFY-hardened overloads of functions,
+- report misuses of stdlib functions at compile-time, and
+- insert run-time checks for uses of functions that might be incorrect, but only
+  if we have the potential of proving the incorrectness of these.
+
+## Breakdown of open
+
+In Bionic, the [FORTIFY'ed implementation of `open`] is quite large. Much like
+`mempcpy`, the `__builtin_open` declaration is simple:
+
+```c
+int open(const char* __path, int __flags, ...);
+```
+
+With some macros expanded, the FORTIFY-hardened header implementation is:
+```c
+int __open_2(const char*, int);
+int __open_real(const char*, int, ...) __asm__(open);
+
+#define __open_modes_useful(flags) (((flags) & O_CREAT) || ((flags) & O_TMPFILE) == O_TMPFILE)
+
+static
+int open(const char* pathname, int flags, mode_t modes, ...) __overloadable
+        __attribute__((diagnose_if(1, "error", "too many arguments")));
+
+static
+__inline__
+__attribute__((no_stack_protector))
+__attribute__((always_inline))
+int open(const char* const __attribute__((pass_object_size(1))) pathname, int flags)
+        __attribute__((overloadable))
+        __attribute__((diagnose_if(
+            __open_modes_useful(flags),
+            "error",
+            "'open' called with O_CREAT or O_TMPFILE, but missing mode"))) {
+#if __ANDROID_API__ >= 17 && __BIONIC_FORTIFY_RUNTIME_CHECKS_ENABLED
+    return __open_2(pathname, flags);
+#else
+    return __open_real(pathname, flags);
+#endif
+}
+static
+__inline__
+__attribute__((no_stack_protector))
+__attribute__((always_inline))
+int open(const char* const __attribute__((pass_object_size(1))) pathname, int flags, mode_t modes)
+        __attribute__((overloadable))
+        __clang_warning_if(!__open_modes_useful(flags) && modes,
+                           "'open' has superfluous mode bits; missing O_CREAT?") {
+    return __open_real(pathname, flags, modes);
+}
+```
+
+Which may be a lot to take in.
+
+Before diving too deeply, please note that the remainder of these subsections
+assume that the programmer didn't make any egregious typos. Moreover, there's no
+real way that Bionic tries to prevent calls to `open` like
+`open("foo", 0, "how do you convert a const char[N] to mode_t?");`. The only
+real C-compatible solution the author can think of is "stamp out many overloads
+to catch sort-of-common instances of this very uncommon typo." This isn't great.
+
+More directly, no effort is made below to recognize calls that, due to
+incompatible argument types, cannot go to any `open` implementation other than
+`__builtin_open`, since it's recognized right here. :)
+
+### Implementation breakdown
+
+This `open` implementation does a few things:
+- Turns calls to `open` with too many arguments into a compile-time error.
+- Diagnoses calls to `open` with missing modes at compile-time and run-time
+  (both cases turn into errors).
+- Emits warnings on calls to `open` with useless mode bits, unless the mode bits
+  are all 0.
+
+One common bit of code not explained below is the `__open_real` declaration above:
+```c
+int __open_real(const char*, int, ...) __asm__(open);
+```
+
+This exists as a way for us to call `__builtin_open` without needing clang to
+have a pre-defined `__builtin_open` function.
+
+#### Compile-time error on too many arguments
+
+```c
+static
+int open(const char* pathname, int flags, mode_t modes, ...) __overloadable
+        __attribute__((diagnose_if(1, "error", "too many arguments")));
+```
+
+Which matches most calls to open that supply too many arguments, since
+`int(const char *, int, ...)` matches less strongly than
+`int(const char *, int, mode_t, ...)` for calls where the 3rd arg can be
+converted to `mode_t` without too much effort. Because of the `diagnose_if`
+attribute, all of these calls turn into compile-time errors.
+
+#### Compile-time or run-time error on missing arguments
+The following overload handles all two-argument calls to `open`.
+```c
+static
+__inline__
+__attribute__((no_stack_protector))
+__attribute__((always_inline))
+int open(const char* const __attribute__((pass_object_size(1))) pathname, int flags)
+        __attribute__((overloadable))
+        __attribute__((diagnose_if(
+            __open_modes_useful(flags),
+            "error",
+            "'open' called with O_CREAT or O_TMPFILE, but missing mode"))) {
+#if __ANDROID_API__ >= 17 && __BIONIC_FORTIFY_RUNTIME_CHECKS_ENABLED
+    return __open_2(pathname, flags);
+#else
+    return __open_real(pathname, flags);
+#endif
+}
+```
+
+Like `mempcpy`, `diagnose_if` handles emitting a compile-time error if the call
+to `open` is broken in a way that's visible to Clang's frontend. This
+essentially boils down to "`open` is being called with a `flags` value that
+requires mode bits to be set."
+
+If that fails to catch a bug, we [unconditionally call `__open_2`], which
+performs a run-time check:
+```c
+int __open_2(const char* pathname, int flags) {
+  if (needs_mode(flags)) __fortify_fatal("open: called with O_CREAT/O_TMPFILE but no mode");
+  return FDTRACK_CREATE_NAME("open", __openat(AT_FDCWD, pathname, force_O_LARGEFILE(flags), 0));
+}
+```
+
+#### Compile-time warning if modes are pointless
+
+Finally, we have the following `open` call:
+```c
+static
+__inline__
+__attribute__((no_stack_protector))
+__attribute__((always_inline))
+int open(const char* const __attribute__((pass_object_size(1))) pathname, int flags, mode_t modes)
+        __attribute__((overloadable))
+        __clang_warning_if(!__open_modes_useful(flags) && modes,
+                           "'open' has superfluous mode bits; missing O_CREAT?") {
+    return __open_real(pathname, flags, modes);
+}
+```
+
+This simply issues a warning if Clang's frontend can determine that `flags`
+isn't necessary. Due to conventions in existing code, a `modes` value of `0` is
+not diagnosed.
+
+#### What about `&open`?
+One yet-unaddressed aspect of the above is how `&open` works. This is thankfully
+a short answer:
+- It happens that `open` takes a parameter of type `const char*`.
+- It happens that `pass_object_size` -- an attribute only applicable to
+  parameters of type `T*` --  makes it impossible to take the address of a
+  function.
+
+Since clang doesn't support a "this function should never have its address
+taken," attribute, Bionic uses the next best thing: `pass_object_size`. :)
+
+## Breakdown of poll
+
+(Preemptively: at the time of writing, Clang has no literal `__builtin_poll`
+builtin. `__builtin_poll` is referenced below to remain consistent with the
+convention established in the Terminology section.)
+
+Bionic's `poll` implementation is closest to `mempcpy` above, though it has a
+few interesting aspects worth examining.
+
+The [full header implementation of `poll`] is, with some macros expanded:
+```c
+#define __bos_fd_count_trivially_safe(bos_val, fds, fd_count) \
+  ((bos_val) == -1) || \
+    (__builtin_constant_p(fd_count) && \
+    (bos_val) >= sizeof(*fds) * (fd_count)))
+
+static
+__inline__
+__attribute__((no_stack_protector))
+__attribute__((always_inline))
+int poll(struct pollfd* const fds __attribute__((pass_object_size(1))), nfds_t fd_count, int timeout)
+    __attribute__((overloadable))
+    __attriubte__((diagnose_if(
+       __builtin_object_size(fds, 1) != -1 && __builtin_object_size(fds, 1) < sizeof(*fds) * fd_count,
+        "error",
+        "in call to 'poll', fd_count is larger than the given buffer"))) {
+  size_t bos_fds = __builtin_object_size(fds, 1);
+  if (!__bos_fd_count_trivially_safe(bos_fds, fds, fd_count)) {
+    return __poll_chk(fds, fd_count, timeout, bos_fds);
+  }
+  return (&poll)(fds, fd_count, timeout);
+}
+```
+
+To get the commonality with `mempcpy` and `open` out of the way:
+- This function is an overload with `__builtin_poll`.
+- The signature is the same, modulo the presence of a `pass_object_size`
+  attribute. Hence, for direct calls, overload resolution will always prefer it
+  over `__builtin_poll`. Taking the address of `poll` is forbidden, so all
+  references to `&poll` actually reference `__builtin_poll`.
+- When `fds` is too small to hold `fd_count` `pollfd`s, Clang will emit a
+  compile-time error if possible using `diagnose_if`.
+- If this can't be observed until run-time, `__poll_chk` verifies this.
+- When `fds` is a constant according to `__builtin_constant_p`, this always
+  compiles into `__poll_chk` for always-broken calls to `poll`, or
+  `__builtin_poll` for always-safe calls to `poll`.
+
+The critical bits to highlight here are on this line:
+```c
+int poll(struct pollfd* const fds __attribute__((pass_object_size(1))), nfds_t fd_count, int timeout)
+```
+
+And this line:
+```c
+  return (&poll)(fds, fd_count, timeout);
+```
+
+Starting with the simplest, we call `__builtin_poll` with `(&poll)(...);`. As
+referenced above, taking the address of an overloaded function where all but one
+overload has a `pass_object_size` attribute on one or more parameters always
+resolves to the function without any `pass_object_size` attributes.
+
+The other line deserves a section. The subtlety of it is almost entirely in the
+use of `pass_object_size(1)` instead of `pass_object_size(0)`. on the `fds`
+parameter, and the corresponding use of `__builtin_object_size(fds, 1);` in the
+body of `poll`.
+
+### Subtleties of __builtin_object_size(p, N)
+
+Earlier in this document, it was said that a full description of each
+attribute/builtin necessary to power FORTIFY was out of scope. This is... only
+somewhat the case when we talk about `__builtin_object_size` and
+`pass_object_size`, especially when their second argument is `1`.
+
+#### tl;dr
+`__builtin_object_size(p, N)` and `pass_object_size(N)`, where `(N & 1) == 1`,
+can only be accurately determined by Clang. LLVM's `@llvm.objectsize` intrinsic
+ignores the value of `N & 1`, since handling `(N & 1) == 1` accurately requires
+data that's currently entirely inaccessible to LLVM, and that is difficult to
+preserve through LLVM's optimization passes.
+
+`pass_object_size`'s "lifting" of the evaluation of
+`__builtin_object_size(p, N)` to the caller is critical, since it allows Clang
+full visibility into the expression passed to e.g., `poll(&foo->bar, baz, qux)`.
+It's not a perfect solution, but it allows `N == 1` to be fully accurate in at
+least some cases.
+
+#### Background
+Clang's implementation of `__builtin_object_size` aims to be compatible with
+GCC's, which has [a decent bit of documentation]. Put simply,
+`__builtin_object_size(p, N)` is intended to evaluate at compile-time how many
+bytes can be accessed after `p` in a well-defined way. Straightforward examples
+of this are:
+```c
+char buf[8];
+assert(__builtin_object_size(buf, N) == 8);
+assert(__builtin_object_size(buf + 1, N) == 7);
+```
+
+This should hold for all values of N that are valid to pass to
+`__builtin_object_size`. The `N` value of `__builtin_object_size` is a mask of
+settings.
+
+##### (N & 2) == ?
+
+This is mostly for completeness sake; in Bionic's FORTIFY implementation, N is
+always either 0 or 1.
+
+If there are multiple possible values of `p` in a call to
+`__builtin_object_size(p, N)`, the second bit in `N` determines the behavior of
+the compiler. If `(N & 2) == 0`, `__builtin_object_size` should return the
+greatest possible size for each possible value of `p`. Otherwise, it should
+return the least possible value. For example:
+
+```c
+char smol_buf[7];
+char buf[8];
+char *p = rand() ? smol_buf : buf;
+assert(__builtin_object_size(p, 0) == 8);
+assert(__builtin_object_size(p, 2) == 7);
+```
+
+##### (N & 1) == 0
+
+`__builtin_object_size(p, 0)` is more or less as simple as the example in the
+Background section directly above. When Clang attempts to evaluate
+`__builtin_object_size(p, 0);` and when LLVM tries to determine the result of a
+corresponding `@llvm.objectsize` call to, they search for the storage underlying
+the pointer in question. If that can be determined, Clang or LLVM can provide an
+answer; otherwise, they cannot.
+
+##### (N & 1) == 1, and the true magic of pass_object_size
+
+`__builtin_object_size(p, 1)` has a less uniform implementation between LLVM and
+Clang. According to GCC's documentation, "If the least significant bit [of
+__builtin_object_size's second argument] is clear, objects are whole variables,
+if it is set, a closest surrounding subobject is considered the object a pointer
+points to."
+
+The "closest surrounding subobject," means that `(N & 1) == 1` depends on type
+information in order to operate in many cases. Consider the following examples:
+```c
+struct Foo {
+  int a;
+  int b;
+};
+
+struct Foo foo;
+assert(__builtin_object_size(&foo, 0) == sizeof(foo));
+assert(__builtin_object_size(&foo, 1) == sizeof(foo));
+assert(__builtin_object_size(&foo->a, 0) == sizeof(foo));
+assert(__builtin_object_size(&foo->a, 1) == sizeof(int));
+
+struct Foo foos[2];
+assert(__builtin_object_size(&foos[0], 0) == 2 * sizeof(foo));
+assert(__builtin_object_size(&foos[0], 1) == sizeof(foo));
+assert(__builtin_object_size(&foos[0]->a, 0) == 2 * sizeof(foo));
+assert(__builtin_object_size(&foos[0]->a, 1) == sizeof(int));
+```
+
+...And perhaps somewhat surprisingly:
+```c
+void example(struct Foo *foo) {
+  // (As a reminder, `-1` is "I don't know" when `(N & 2) == 0`.)
+  assert(__builtin_object_size(foo, 0) == -1);
+  assert(__builtin_object_size(foo, 1) == -1);
+  assert(__builtin_object_size(foo->a, 0) == -1);
+  assert(__builtin_object_size(foo->a, 1) == sizeof(int));
+}
+```
+
+In Clang, [this type-aware requirement poses problems for us]: Clang's frontend
+knows everything we could possibly want about the types of variables, but
+optimizations are only performed by LLVM. LLVM has no reliable source for C or
+C++ data types, so calls to `__builtin_object_size(p, N)` that cannot be
+resolved by clang are lowered to the equivalent of
+`__builtin_object_size(p, N & ~1)` in LLVM IR.
+
+Moreover, Clang's frontend is the best-equipped part of the compiler to
+accurately determine the answer for `__builtin_object_size(p, N)`, given we know
+what `p` is. LLVM is the best-equipped part of the compiler to determine the
+value of `p`. This ordering issue is unfortunate.
+
+This is where `pass_object_size(N)` comes in. To summarize [the docs for
+`pass_object_size`], it evaluates `__builtin_object_size(p, N)` within the
+context of the caller of the function annotated with `pass_object_size`, and
+passes the value of that into the callee as an invisible parameter. All calls to
+`__builtin_object_size(parameter, N)` are substituted with references to this
+invisible parameter.
+
+Putting this plainly, Clang's frontend struggles to evaluate the following:
+```c
+int foo(void *p) {
+  return __builtin_object_size(p, 1);
+}
+
+void bar() {
+  struct { int i, j } k;
+  // The frontend can't figure this interprocedural objectsize out, so it gets lowered to
+  // LLVM, which determines that the answer here is sizeof(k).
+  int baz = foo(&k.i);
+}
+```
+
+However, with the magic of `pass_object_size`, we get one level of inlining to
+look through:
+```c
+int foo(void *const __attribute__((pass_object_size(1))) p) {
+  return __builtin_object_size(p, 1);
+}
+
+void bar() {
+  struct { int i, j } k;
+  // Due to pass_object_size, this is equivalent to:
+  // int baz = foo(&k.i, __builtin_object_size(&k.i, 1));
+  // ...and `int foo(void *)` is actually equivalent to:
+  // int foo(void *const, size_t size) {
+  //   return size;
+  // }
+  int baz = foo(&k.i);
+}
+```
+
+So we can obtain an accurate result in this case.
+
+##### What about pass_object_size(0)?
+It's sort of tangential, but if you find yourself wondering about the utility of
+`pass_object_size(0)` ... it's somewhat split. `pass_object_size(0)` in Bionic's
+FORTIFY exists mostly for visual consistency, simplicity, and as a useful way to
+have e.g., `&mempcpy` == `&__builtin_mempcpy`.
+
+Outside of these fringe benefits, all of the functions with
+`pass_object_size(0)` on parameters are marked with `always_inline`, so
+"lifting" the `__builtin_object_size` call isn't ultimately very helpful. In
+theory, users can always have something like:
+
+```c
+// In some_header.h
+// This function does cool and interesting things with the `__builtin_object_size` of its parameter,
+// and is able to work with that as though the function were defined inline.
+void out_of_line_function(void *__attribute__((pass_object_size(0))));
+```
+
+Though the author isn't aware of uses like this in practice, beyond a few folks
+on LLVM's mailing list seeming interested in trying it someday.
+
+#### Wrapping up
+In the (long) section above, two things were covered:
+- The use of `(&poll)(...);` is a convenient shorthand for calling
+  `__builtin_poll`.
+- `__builtin_object_size(p, N)` with `(N & 1) == 1` is not easy for Clang to
+  answer accurately, since it relies on type info only available in the
+  frontend, and it sometimes relies on optimizations only available in the
+  middle-end. `pass_object_size` helps mitigate this.
+
+## Miscellaneous Notes
+The above should be a roughly comprehensive view of how FORTIFY works in the
+real world. The main thing it fails to mention is the use of [the `diagnose_as_builtin` attribute] in Clang.
+
+As time has moved on, Clang has increasingly gained support for emitting
+warnings that were previously emitted by FORTIFY machinery.
+`diagnose_as_builtin` allows us to remove the `diagnose_if`s from some of the
+`static inline` overloads of stdlib functions above, so Clang may diagnose them
+instead.
+
+Clang's built-in diagnostics are often better than `diagnose_if` diagnostics,
+since Clang can format its diagnostics to include e.g., information about the
+sizes of buffers in a suspect call to a function. `diagnose_if` can only have
+the compiler output constant strings.

- * Return correctly rounded sqrt.
- *           ------------------------------------------
- *	     |  Use the hardware sqrt if you have one |
- *           ------------------------------------------
- * Method: 
- *   Bit by bit method using integer arithmetic. (Slow, but portable) 
- *   1. Normalization
- *	Scale x to y in [1,4) with even powers of 2: 
- *	find an integer k such that  1 <= (y=x*2^(2k)) < 4, then
- *		sqrt(x) = 2^k * sqrt(y)
- *   2. Bit by bit computation
- *	Let q  = sqrt(y) truncated to i bit after binary point (q = 1),
- *	     i							 0
- *                                     i+1         2
- *	    s  = 2*q , and	y  =  2   * ( y - q  ).		(1)
- *	     i      i            i                 i
- *                                                        
- *	To compute q    from q , one checks whether 
- *		    i+1       i                       
- *
- *			      -(i+1) 2
- *			(q + 2      ) <= y.			(2)
- *     			  i
- *							      -(i+1)
- *	If (2) is false, then q   = q ; otherwise q   = q  + 2      .
- *		 	       i+1   i             i+1   i
- *
- *	With some algebric manipulation, it is not difficult to see
- *	that (2) is equivalent to 
- *                             -(i+1)
- *			s  +  2       <= y			(3)
- *			 i                i
- *
- *	The advantage of (3) is that s  and y  can be computed by 
- *				      i      i
- *	the following recurrence formula:
- *	    if (3) is false
- *
- *	    s     =  s  ,	y    = y   ;			(4)
- *	     i+1      i		 i+1    i
- *
- *	    otherwise,
- *                         -i                     -(i+1)
- *	    s	  =  s  + 2  ,  y    = y  -  s  - 2  		(5)
- *           i+1      i          i+1    i     i
- *				
- *	One may easily use induction to prove (4) and (5). 
- *	Note. Since the left hand side of (3) contain only i+2 bits,
- *	      it does not necessary to do a full (53-bit) comparison 
- *	      in (3).
- *   3. Final rounding
- *	After generating the 53 bits result, we compute one more bit.
- *	Together with the remainder, we can decide whether the
- *	result is exact, bigger than 1/2ulp, or less than 1/2ulp
- *	(it will never equal to 1/2ulp).
- *	The rounding mode can be detected by checking whether
- *	huge + tiny is equal to huge, and whether huge - tiny is
- *	equal to huge for some floating point number "huge" and "tiny".
- *		
- * Special cases:
- *	sqrt(+-0) = +-0 	... exact
- *	sqrt(inf) = inf
- *	sqrt(-ve) = NaN		... with invalid signal
- *	sqrt(NaN) = NaN		... with invalid signal for signaling NaN
- *
- * Other methods : see the appended file at the end of the program below.

--------------
-(This is a copy of a drafted paper by Prof W. Kahan 
-and K.C. Ng, written in May, 1986)
-
-	Two algorithms are given here to implement sqrt(x) 
-	(IEEE double precision arithmetic) in software.
-	Both supply sqrt(x) correctly rounded. The first algorithm (in
-	Section A) uses newton iterations and involves four divisions.
-	The second one uses reciproot iterations to avoid division, but
-	requires more multiplications. Both algorithms need the ability
-	to chop results of arithmetic operations instead of round them, 
-	and the INEXACT flag to indicate when an arithmetic operation
-	is executed exactly with no roundoff error, all part of the 
-	standard (IEEE 754-1985). The ability to perform shift, add,
-	subtract and logical AND operations upon 32-bit words is needed
-	too, though not part of the standard.
-
-A.  sqrt(x) by Newton Iteration
-
-   (1)	Initial approximation
-
-	Let x0 and x1 be the leading and the trailing 32-bit words of
-	a floating point number x (in IEEE double format) respectively 
-
-	    1    11		     52				  ...widths
-	   ------------------------------------------------------
-	x: |s|	  e     |	      f				|
-	   ------------------------------------------------------
-	      msb    lsb  msb				      lsb ...order
-
- 
-	     ------------------------  	     ------------------------
-	x0:  |s|   e    |    f1     |	 x1: |          f2           |
-	     ------------------------  	     ------------------------
-
-	By performing shifts and subtracts on x0 and x1 (both regarded
-	as integers), we obtain an 8-bit approximation of sqrt(x) as
-	follows.
-
-		k  := (x0>>1) + 0x1ff80000;
-		y0 := k - T1[31&(k>>15)].	... y ~ sqrt(x) to 8 bits
-	Here k is a 32-bit integer and T1[] is an integer array containing
-	correction terms. Now magically the floating value of y (y's
-	leading 32-bit word is y0, the value of its trailing word is 0)
-	approximates sqrt(x) to almost 8-bit.
-
-	Value of T1:
-	static int T1[32]= {
-	0,	1024,	3062,	5746,	9193,	13348,	18162,	23592,
-	29598,	36145,	43202,	50740,	58733,	67158,	75992,	85215,
-	83599,	71378,	60428,	50647,	41945,	34246,	27478,	21581,
-	16499,	12183,	8588,	5674,	3403,	1742,	661,	130,};
-
-    (2)	Iterative refinement
-
-	Apply Heron's rule three times to y, we have y approximates 
-	sqrt(x) to within 1 ulp (Unit in the Last Place):
-
-		y := (y+x/y)/2		... almost 17 sig. bits
-		y := (y+x/y)/2		... almost 35 sig. bits
-		y := y-(y-x/y)/2	... within 1 ulp
-
-
-	Remark 1.
-	    Another way to improve y to within 1 ulp is:
-
-		y := (y+x/y)		... almost 17 sig. bits to 2*sqrt(x)
-		y := y - 0x00100006	... almost 18 sig. bits to sqrt(x)
-
-				2
-			    (x-y )*y
-		y := y + 2* ----------	...within 1 ulp
-			       2
-			     3y  + x
-
-
-	This formula has one division fewer than the one above; however,
-	it requires more multiplications and additions. Also x must be
-	scaled in advance to avoid spurious overflow in evaluating the
-	expression 3y*y+x. Hence it is not recommended uless division
-	is slow. If division is very slow, then one should use the 
-	reciproot algorithm given in section B.
-
-    (3) Final adjustment
-
-	By twiddling y's last bit it is possible to force y to be 
-	correctly rounded according to the prevailing rounding mode
-	as follows. Let r and i be copies of the rounding mode and
-	inexact flag before entering the square root program. Also we
-	use the expression y+-ulp for the next representable floating
-	numbers (up and down) of y. Note that y+-ulp = either fixed
-	point y+-1, or multiply y by nextafter(1,+-inf) in chopped
-	mode.
-
-		I := FALSE;	... reset INEXACT flag I
-		R := RZ;	... set rounding mode to round-toward-zero
-		z := x/y;	... chopped quotient, possibly inexact
-		If(not I) then {	... if the quotient is exact
-		    if(z=y) {
-		        I := i;	 ... restore inexact flag
-		        R := r;  ... restore rounded mode
-		        return sqrt(x):=y.
-		    } else {
-			z := z - ulp;	... special rounding
-		    }
-		}
-		i := TRUE;		... sqrt(x) is inexact
-		If (r=RN) then z=z+ulp	... rounded-to-nearest
-		If (r=RP) then {	... round-toward-+inf
-		    y = y+ulp; z=z+ulp;
-		}
-		y := y+z;		... chopped sum
-		y0:=y0-0x00100000;	... y := y/2 is correctly rounded.
-	        I := i;	 		... restore inexact flag
-	        R := r;  		... restore rounded mode
-	        return sqrt(x):=y.
-		    
-    (4)	Special cases
-
-	Square root of +inf, +-0, or NaN is itself;
-	Square root of a negative number is NaN with invalid signal.
-
-
-B.  sqrt(x) by Reciproot Iteration
-
-   (1)	Initial approximation
-
-	Let x0 and x1 be the leading and the trailing 32-bit words of
-	a floating point number x (in IEEE double format) respectively
-	(see section A). By performing shifs and subtracts on x0 and y0,
-	we obtain a 7.8-bit approximation of 1/sqrt(x) as follows.
-
-	    k := 0x5fe80000 - (x0>>1);
-	    y0:= k - T2[63&(k>>14)].	... y ~ 1/sqrt(x) to 7.8 bits
-
-	Here k is a 32-bit integer and T2[] is an integer array 
-	containing correction terms. Now magically the floating
-	value of y (y's leading 32-bit word is y0, the value of
-	its trailing word y1 is set to zero) approximates 1/sqrt(x)
-	to almost 7.8-bit.
-
-	Value of T2:
-	static int T2[64]= {
-	0x1500,	0x2ef8,	0x4d67,	0x6b02,	0x87be,	0xa395,	0xbe7a,	0xd866,
-	0xf14a,	0x1091b,0x11fcd,0x13552,0x14999,0x15c98,0x16e34,0x17e5f,
-	0x18d03,0x19a01,0x1a545,0x1ae8a,0x1b5c4,0x1bb01,0x1bfde,0x1c28d,
-	0x1c2de,0x1c0db,0x1ba73,0x1b11c,0x1a4b5,0x1953d,0x18266,0x16be0,
-	0x1683e,0x179d8,0x18a4d,0x19992,0x1a789,0x1b445,0x1bf61,0x1c989,
-	0x1d16d,0x1d77b,0x1dddf,0x1e2ad,0x1e5bf,0x1e6e8,0x1e654,0x1e3cd,
-	0x1df2a,0x1d635,0x1cb16,0x1be2c,0x1ae4e,0x19bde,0x1868e,0x16e2e,
-	0x1527f,0x1334a,0x11051,0xe951,	0xbe01,	0x8e0d,	0x5924,	0x1edd,};
-
-    (2)	Iterative refinement
-
-	Apply Reciproot iteration three times to y and multiply the
-	result by x to get an approximation z that matches sqrt(x)
-	to about 1 ulp. To be exact, we will have 
-		-1ulp < sqrt(x)-z<1.0625ulp.
-	
-	... set rounding mode to Round-to-nearest
-	   y := y*(1.5-0.5*x*y*y)	... almost 15 sig. bits to 1/sqrt(x)
-	   y := y*((1.5-2^-30)+0.5*x*y*y)... about 29 sig. bits to 1/sqrt(x)
-	... special arrangement for better accuracy
-	   z := x*y			... 29 bits to sqrt(x), with z*y<1
-	   z := z + 0.5*z*(1-z*y)	... about 1 ulp to sqrt(x)
-
-	Remark 2. The constant 1.5-2^-30 is chosen to bias the error so that
-	(a) the term z*y in the final iteration is always less than 1; 
-	(b) the error in the final result is biased upward so that
-		-1 ulp < sqrt(x) - z < 1.0625 ulp
-	    instead of |sqrt(x)-z|<1.03125ulp.
-
-    (3)	Final adjustment
-
-	By twiddling y's last bit it is possible to force y to be 
-	correctly rounded according to the prevailing rounding mode
-	as follows. Let r and i be copies of the rounding mode and
-	inexact flag before entering the square root program. Also we
-	use the expression y+-ulp for the next representable floating
-	numbers (up and down) of y. Note that y+-ulp = either fixed
-	point y+-1, or multiply y by nextafter(1,+-inf) in chopped

-	R := RZ;		... set rounding mode to round-toward-zero
-	switch(r) {
-	    case RN:		... round-to-nearest
-	       if(x<= z*(z-ulp)...chopped) z = z - ulp; else
-	       if(x<= z*(z+ulp)...chopped) z = z; else z = z+ulp;

-
-	Remark 3. The above comparisons can be done in fixed point. For
-	example, to compare x and w=z*z chopped, it suffices to compare
-	x1 and w1 (the trailing parts of x and w), regarding them as
-	two's complement integers.
-
-	...Is z an exact square root?
-	To determine whether z is an exact square root of x, let z1 be the
-	trailing part of z, and also let x0 and x1 be the leading and
-	trailing parts of x.
-
-	If ((z1&0x03ffffff)!=0)	... not exact if trailing 26 bits of z!=0
-	    I := 1;		... Raise Inexact flag: z is not exact
-	else {
-	    j := 1 - [(x0>>20)&1]	... j = logb(x) mod 2
-	    k := z1 >> 26;		... get z's 25-th and 26-th 
-					    fraction bits
-	    I := i or (k&j) or ((k&(j+j+1))!=(x1&3));
-	}
-	R:= r		... restore rounded mode
-	return sqrt(x):=z.
-
-	If multiplication is cheaper then the foregoing red tape, the 
-	Inexact flag can be evaluated by
-
-	    I := i;
-	    I := (z*z!=x) or I.
-
-	Note that z*z can overwrite I; this value must be sensed if it is 
-	True.
-
-	Remark 4. If z*z = x exactly, then bit 25 to bit 0 of z1 must be
-	zero.
-
-		    --------------------
-		z1: |        f2        | 
-		    --------------------
-		bit 31		   bit 0
-
-	Further more, bit 27 and 26 of z1, bit 0 and 1 of x1, and the odd
-	or even of logb(x) have the following relations:
-
-	-------------------------------------------------
-	bit 27,26 of z1		bit 1,0 of x1	logb(x)

-	00			00		odd and even
-	01			01		even
-	10			10		odd

-//                     ALGORITHM DESCRIPTION
-//                     ---------------------
-//
-//  To compute acos(s), separate schemes are used when s is in different
-//  intervals.
-//
-//  |s| in [2^{-4}, sqrt(3)/2):
-//       Let t=2^k*1.b1 b2..b6 1, where s=2^k*1.b1 b2 .. b52
-//       acos(s)=pi/2-asin(t)-asin(r), where r=s*sqrt(1-t^2)-t*sqrt(1-s^2)
-//       asin(r)-r evaluated as 7-degree polynomial (c3*r^3+c5*r^5+c7*r^7)
-//       For the first degree term, r is evaluated as
-//                R=(s^2-t^2)/(sqrt(1-t^2)*s+sqrt(1-s^2)*t)
-//       (sqrt(1-t^2) read from table)
-//  The main source of error is still R (may still be affected by up to 3 ulps
-//  of rounding error). The table size must be sufficiently large, to minimize
-//  this effect.
-//
-//  |s| in [sqrt(3)/2, 255/256):
-//       Let t=2^k*1.b1 b2..b6 1, where sqrt(1-s^2)=2^k*1.b1 b2 .. b52 (rounded)
-//       acos(|s|)=asin(t)-asin(r), r=s*t-sqrt(1-s^2)*sqrt(1-t^2)
-//   acos(-|s|)=pi-acos(|s|)
-//       (The -PI constant, or 0, is added to the result. The sign is set at
-//        the end)
-//       asin(r) evaluated as a polynomial (same as above)
-//       The first degree term is evaluated as
-//                        r=(s^2+t^2-1)/(s*t+sqrt(1-s^2)*sqrt(1-t^2))
-//
-//  |s|<2^{-4}: acos(s)=pi/2-asin(s)
-//              evaluate asin(s) as 13-degree polynomial
-//
-//  |s| in [255/256,1): acos(|s|)=2*asin(q), where q=sqrt((1-|s|)/2)
-//  asin(q) is evaluated as 13-degree polynomial
-//      q^2=(1-|s|)/2 is obtained in advance
-//         2*q*eps ~ ((1-|s|)/2-q^2)/q used for first term
-//   acos(-|s|)=pi-acos(|s|)
-//       (The -PI constant, or 0, is added to the result. The sign is set at
-//        the end)
-//
-// Special cases:
-//  acos(NaN) = quiet NaN, and raise invalid exception
-//  acos(INF) = QNaN and raise invalid exception
-//  acos(x) = QNaN and raise invalid exception, for |x|>1.0
-//  acos(1) = +0
-//

-//                     ALGORITHM DESCRIPTION
-//                     ---------------------
-//
-//  To compute asin(s), separate schemes are used when s is in different
-//  intervals.
-//
-//  |s| in [2^{-4}, sqrt(3)/2):
-//       Let t=2^k*1.b1 b2..b6 1, where s=2^k*1.b1 b2 .. b52
-//       asin(s)=asin(t)+asin(r), where r=s*sqrt(1-t^2)-t*sqrt(1-s^2)
-//       asin(r)-r evaluated as 7-degree polynomial (c3*r^3+c5*r^5+c7*r^7)
-//       For the first degree term, r is evaluated as
-//                R=(s^2-t^2)/(sqrt(1-t^2)*s+sqrt(1-s^2)*t)
-//       (sqrt(1-t^2) read from table)
-//  The main source of error is still R (may still be affected by up to 3 ulps
-//  of rounding error). The table size must be sufficiently large, to minimize
-//  this effect.
-//
-//  |s| in [sqrt(3)/2, 255/256):
-//       Let t=2^k*1.b1 b2..b6 1, where sqrt(1-s^2)=2^k*1.b1 b2 .. b52 (rounded)
-//       asin(|s|)=pi/2-asin(t)+asin(r), r=s*t-sqrt(1-s^2)*sqrt(1-t^2)
-//       asin(r) evaluated as polynomial (same as above)
-//       The first degree term is evaluated as
-//                        r=(s^2+t^2-1)/(s*t+sqrt(1-s^2)*sqrt(1-t^2))
-//
-//  |s|<2^{-4}: evaluate as 13-degree polynomial
-//
-//  |s| in [255/256,1): asin(|s|)=pi/2-asin(sqrt(1-s^2))
-//         use 17-degree polynomial, get error term
-//         Q*eps ~ (1-s^2-Q^2)/(2*Q) for first term
-//                 ( Q(1+eps)=sqrt(1-s^2) )
-//
-// Special cases:
-//  asin(NaN) = quiet NaN, and raise invalid exception
-//  asin(INF) = QNaN and raise invalid exception
-//  asin(x) = QNaN and raise invalid exception, for |x|>1.0
-//  asin(+/-0) = +/-0

-//                     ALGORITHM DESCRIPTION
-//                     ---------------------
-//
-//
-//1. The method is based on the relationship of atan2(Y,X) to atan(|Y/X|)
-//   as follows.
-//                   /  sign(Y) atan(|Y/X|)                if X > 0
-//       atan2(Y,X) =
-//                   \  sign(Y)*pi  - sign(Y)*atan(|Y/X|)  if X < 0
-//
-//   Thus, atan2(Y,X) is of the form  atan2(Y,X) = PI + sgn*atan(|Y/X|)
-//   where PI and sgn can be determined by the four possible combinations of
-//   of the pair (sign(X),sign(Y)). We concentrate on the numerical method
-//   for atan(|Y/X|).
-//
-//2. For |Y/X| < 2^(-64), atan(|Y/X|) ~=~ |Y/X|. Hence, atan2(Y,X) is  Y/X
-//   if X > 0, and sign(Y)*pi otherwise.
-//3. For |Y/X| >= 2^(65), atan(|Y/X|) ~=~ pi/2. Hence atan2(Y,X) is sign(Y)pi/2.
-//4. For 2^(-64) <= |Y/X| < 2^(-5), atan(|Y/X|) is approximated by a polynomial
-//   of the form  Z + Z*E*polynomial(E), where Z = |Y/X| and E = Z*Z.
-//5. For |Y/X| > 2^(5), atan(|Y/X|) = pi/2 + atan(-|X/Y|), and atan(-|X/Y|) is
-//   calculated using the polynomial in 4 above.
-//6. For 2^(-5) <= |Y/X| <= 2^(5), we employ a table lookup method. First,
-//   we obtain B = 2^k * 1.b1 b2 b3 b4 = 2^k * (1+k/16) that approximate
-//   |Y/X| to approximately 5 significant bits. Hence, atan(|Y/X|) is
-//
-//      atan(|Y/X|)  =  atan(B) + atan(Z), where  Z = (|Y|-B|X|)/(|X|+B|Y|).
-//                  ~=~   tau   + Z + Z*E*polynomial(E), where E = Z*Z.
-//
-//   B has the range from 2^(-6)*(1+14/16) to 2^5 = 2^(5)*(1+0/16), totally
-//   163 possible values. These values are calculated beforehand and stored
-//   in a table. The polynomial is the one used in 4.
-//
-// Special cases:
-//  atan2(+-0, +0) = +-0
-//  atan2(+-0, -0) = +-pi
-//  atan2(+-0, x) = +-0, for x > 0, and +-pi, for x < 0
-//  atan2(y, +-0) = +pi/2 for y > 0, and -pi/2 for y < 0
-//  atan2(+-y, +INF) = +-0, for finite y > 0
-//  atan2(+-y, -INF) = +-pi, for finite y > 0
-//  atan2(+-INF, x) = +-pi/2, for finite x
-//  atan2(+-INF, +INF) = +-pi/4
-//  atan2(+-INF, -INF) = +-3*pi/4

-//                     ALGORITHM DESCRIPTION
-//                     ---------------------
-//
-//  cosh(x)=(exp(x)+exp(-x))/2
-//
-//  Let |x|=xH+xL (upper 26 bits, lower 27 bits)
-//  log2(e) rounded to 26 bits (high part) plus a double precision low part is
-//          L2EH+L2EL (upper 26, lower 53 bits)
-//
-//  Let xH*L2EH=k+f+r`, where (k+f)*2^7=int(xH*L2EH*2^7),
-//                              f=0.b1 b2 ... b7, k integer
-//  2^f is approximated as Tp[f]+Dp[f], and 2^{-f} as Tn[f]+Dn[f]
-//  Tp stores higher 53 bits, Dp stores (2^f-Tp[f]) rounded to double precision
-//
-//  e^|x|=2^{k+f}*2^r, r=r`+xL*L2EH+|x|*L2EL, |r|<2^{-8}+2^{-14},
-//                       for |x| in [1/8,3*2^8)
-//  e^{-|x|}=2^{-k-f}*2^{-r}
-//
-//  e^|x| is approximated as 2^k*Tp+2^k*Tp*c1*r(1+c2*r+..+c5*r^4)+2^k*Dp=
-//                           =2^k*Tp+2^k*Tp*P15+2^k*Dp
-//  e^{-|x|} approximated as 2^{-k}*Tn-2^{-k}*Tn*c1*r(1-c2*r+..+c5*r^4)
-//
-//  For |x| in [1/8, 3*2^7), cosh(x) is formed as
-//   RN(2^k*Tp+2^{-k}*Tn)+2^k*Tp*P15+2^{-k}*Tn*P`15+2^{-k}*TnL+2^{-k}*Dn+2^k*Dp
-//
-//  For |x| in [3*2^7, 3*2^8), (e^|x|)/2 is returned, and
-//  the result is checked for overflow.
-//
-//  For |x|<1/8, a Taylor polynomial expansion is used (degree 10)
-//  (error bound for polynomial expansion is below 0.501 ulp)
-//
-// Special cases:
-//  cosh(NaN) = quiet NaN, and raise invalid exception
-//  cosh(INF) = that INF
-//  cosh(0)=1
-//  for finite argument, only cosh(0)=1 is exact
-//  For IEEE double
-//  cosh(x) overflows
-//  for x > 710.47586007394386342639336362481117248535156250 = MAXLOG+log(2)

-//                     ALGORITHM DESCRIPTION
-//                     ---------------------
-//
-// X87 version:
-// Use 80-bit FPU precision fmul, fsqrt to compute square and sqrt.
-//
-// SSE version:
-// Swap x, y if |x|<|y|
-// For x=2^k*x, get y=y*2^(-k)
-// Get S ~ sqrt(x^2+y^2)  (leading 1 + leading 25 mantissa bits)
-//
-// Get D = ( RN(x^2+y^2) - S^2 ) + ( x^2 - RN(x^2) ) +
-//                               + ( y^2 - ((RN(x^2+y^2)-RN(x^2)) )

-//                     ALGORITHM DESCRIPTION
-//                     ---------------------
-//
-//    Let x=2^k * mx, mx in [1,2)
-//
-//    Get B~1/mx based on the output of rcpss instruction (B0)
-//    B = int((B0*LH*2^7+0.5))/2^7
-//    LH is a short approximation for log10(e)
-//
-//    Reduced argument: r=B*mx-LH (computed accurately in high and low parts)
-//
-//    Result:  k*log10(2) - log(B) + p(r)
-//             p(r) is a degree 7 polynomial
-//             -log(B) read from data table (high, low parts)
-//             Result is formed from high and low parts
-//
-// Special cases:
-//  log10(0) = -INF with divide-by-zero exception raised                                           
-//  log10(1) = +0
-//  log10(x) = NaN with invalid exception raised if x < -0, including -INF
-//  log10(+INF) = +INF

-//                     ALGORITHM DESCRIPTION
-//                     ---------------------
-//
-//  sinh(x)=(exp(x)-exp(-x))/2
-//
-//  Let |x|=xH+xL (upper 26 bits, lower 27 bits)
-//  log2(e) rounded to 26 bits (high part) plus a double precision low part is
-//          L2EH+L2EL (upper 26, lower 53 bits)
-//
-//  Let xH*L2EH=k+f+r`, where (k+f)*2^7=int(xH*L2EH*2^7),
-//                              f=0.b1 b2 ... b7, k integer
-//  2^f is approximated as Tp[f]+Dp[f], and 2^{-f} as Tn[f]+Dn[f]
-//  Tp stores the high 53 bits, Dp stores (2^f-Tp[f]) rounded to double precision
-//
-//  e^|x|=2^{k+f}*2^r, r=r`+xL*L2EH+|x|*L2EL, |r|<2^{-8}+2^{-14},
-//                       for |x| in [23/64,3*2^7)
-//  e^{-|x|}=2^{-k-f}*2^{-r}
-//
-//  e^|x| is approximated as 2^k*Tp+2^k*Tp*c1*r(1+c2*r+..+c5*r^4)+2^k*Dp=
-//                           =2^k*Tp+2^k*Tp*P15+2^k*Dp
-//  e^{-|x|} approximated as 2^{-k}*Tn-2^{-k}*Tn*c1*r(1-c2*r+..+c5*r^4)+2^{-k}*Dn
-//
-//  For |x| in [1/8, 3*2^7), sinh(x) is formed as
-//      RN(2^k*Tp-2^{-k}*Tn)+2^k*Tp*P15-2^{-k}*Tn*P`15-2^{-k}*TnL-2^{-k}*Dn+2^k*Dp
-//
-//  For x in (3*2^7, 3*2^8), sign(x)*(e^|x|)/2 is returned, and
-//  the result is checked for overflow.
-//
-//  For |x|<23/64, a Taylor polynomial expansion is used (degree 13)
-//  To reduce rounding errors, the p3*x^3 term is computed as
-//     (p3*xh^3)_high+[(p3*xl*(3*x*xh+xl^2))+(p3*xh^3)_low],
-//  where x=xh+xl, (xh are the leading 17 bits of x), and
-//     (p3*xh^3)_high=RN(x+p3*xh^3)-x
-//  (error bound for polynomial expansion is below 0.51 ulp)
-//
-// Special cases:
-//  sinh(NaN) = quiet NaN, and raise invalid exception
-//  sinh(+/-INF) = +/-INF
-//  sinh(x) = x for subnormals
-//  for finite argument, only sinh(0)=0 is exact
-//  For IEEE double
-//    sinh(x) overflows  for x > 
-//    710.47586007394386342639336362481117248535156250 = MAXLOG+log(2)

-//                     ALGORITHM DESCRIPTION
-//                     ---------------------
-//
-// This implementation uses the main path for |x| in [2^{-5},2^65).
-// For |x| in [2^{-64},2^{-5}), a secondary path is used.
-// For the biased exponent of X within 3FFH-64 and 3FF+64, we use one branch.
-// We use the following definition of B and X` so that the formula
-// atan(X) = Tau + atan( (X`-B) / (One + BX) ) is correct
-//
-// X = (-1)^s * 2^k * 1. x1 x2 ... x52
-//
-// Define X`  = 0 if k >= 5; and X`  = |X| otherwise
-// Define One = 0 if k >= 5; and One = 1 otherwise
-// Define B  = 0 if k <= -6; B =  2^k * 1.x1 x2 x3 x4 1  if -5 <= k <= 4
-// Define B  =  2^5 * 1.0 0 ... 0   if  k >= 5
-//
-// Tau is 0 if k <= -6;
-// Tau is atan( B )  if -5 <= k <= 4
-// Tau is pi/2 if k >= 5
-//
-// Special cases:
-//  atan(NaN) = quiet NaN
-//  atan(+/-INF) = +/-Pi/2
-//  atan(+/-0) = +/-0
-//

-//                     ALGORITHM DESCRIPTION
-//                     ---------------------
-//
-//   Assume x=2^{3*k+j} * 1.b1 b2 ... b5 b6 ... b52, where j = 0,1,2.
-//   Let r=(x*2^{-3k-j} - 1.b1 b2 ... b5 1)* rcp[b1 b2 ..b5],
-//   where rcp[b1 b2 .. b5]=1/(1.b1 b2 b3 b4 b5 1) in double precision
-//   cbrt(2^j * 1. b1 b2 .. b5 1) is approximated as T[j][b1..b5]+D[j][b1..b5]
-//   (T stores the high 53 bits, D stores the low order bits)
-//   Result=2^k*T+(2^k*T*r)*P+2^k*D
-//   where P=p1+p2*r+..+p8*r^7
-//
-// Special cases:
-//  cbrt(NaN) = quiet NaN, and raise invalid exception
-//  cbrt(INF) = that INF
-//  cbrt(+/-0) = +/-0
-//

-//                     ALGORITHM DESCRIPTION
-//                     ---------------------
-//
-//     1. RANGE REDUCTION
-//
-//     We perform an initial range reduction from X to r with
-//
-//          X =~= N * pi/32 + r
-//
-//     so that |r| <= pi/64 + epsilon. We restrict inputs to those
-//     where |N| <= 932560. Beyond this, the range reduction is
-//     insufficiently accurate. For extremely small inputs, 
-//     denormalization can occur internally, impacting performance.
-//     This means that the main path is actually only taken for
-//     2^-252 <= |X| < 90112.
-//
-//     To avoid branches, we perform the range reduction to full
-//     accuracy each time.
-//
-//          X - N * (P_1 + P_2 + P_3)
-//
-//     where P_1 and P_2 are 32-bit numbers (so multiplication by N
-//     is exact) and P_3 is a 53-bit number. Together, these
-//     approximate pi well enough for all cases in the restricted
-//     range.
-//
-//     The main reduction sequence is:
-//
-//             y = 32/pi * x
-//             N = integer(y)
-//     (computed by adding and subtracting off SHIFTER)
-//
-//             m_1 = N * P_1
-//             m_2 = N * P_2
-//             r_1 = x - m_1
-//             r = r_1 - m_2
-//     (this r can be used for most of the calculation)
-//
-//             c_1 = r_1 - r
-//             m_3 = N * P_3
-//             c_2 = c_1 - m_2
-//             c = c_2 - m_3
-//
-//     2. MAIN ALGORITHM
-//
-//     The algorithm uses a table lookup based on B = M * pi / 32
-//     where M = N mod 64. The stored values are:
-//       sigma             closest power of 2 to cos(B)
-//       C_hl              53-bit cos(B) - sigma
-//       S_hi + S_lo       2 * 53-bit sin(B)
-//
-//     The computation is organized as follows:
-//
-//          sin(B + r + c) = [sin(B) + sigma * r] +
-//                           r * (cos(B) - sigma) +
-//                           sin(B) * [cos(r + c) - 1] +
-//                           cos(B) * [sin(r + c) - r]
-//
-//     which is approximately:
-//
-//          [S_hi + sigma * r] +
-//          C_hl * r +
-//          S_lo + S_hi * [(cos(r) - 1) - r * c] +
-//          (C_hl + sigma) * [(sin(r) - r) + c]
-//
-//     and this is what is actually computed. We separate this sum
-//     into four parts:
-//
-//          hi + med + pols + corr
-//
-//     where
-//
-//          hi       = S_hi + sigma r
-//          med      = C_hl * r
-//          pols     = S_hi * (cos(r) - 1) + (C_hl + sigma) * (sin(r) - r)
-//          corr     = S_lo + c * ((C_hl + sigma) - S_hi * r)
-//
-//     3. POLYNOMIAL
-//
-//     The polynomial S_hi * (cos(r) - 1) + (C_hl + sigma) *
-//     (sin(r) - r) can be rearranged freely, since it is quite
-//     small, so we exploit parallelism to the fullest.
-//
-//          psc4       =   SC_4 * r_1
-//          msc4       =   psc4 * r
-//          r2         =   r * r
-//          msc2       =   SC_2 * r2
-//          r4         =   r2 * r2
-//          psc3       =   SC_3 + msc4
-//          psc1       =   SC_1 + msc2
-//          msc3       =   r4 * psc3
-//          sincospols =   psc1 + msc3
-//          pols       =   sincospols *
-//                         <S_hi * r^2 | (C_hl + sigma) * r^3>
-//
-//     4. CORRECTION TERM
-//
-//     This is where the "c" component of the range reduction is
-//     taken into account; recall that just "r" is used for most of
-//     the calculation.
-//
-//          -c   = m_3 - c_2
-//          -d   = S_hi * r - (C_hl + sigma)
-//          corr = -c * -d + S_lo
-//
-//     5. COMPENSATED SUMMATIONS
-//
-//     The two successive compensated summations add up the high
-//     and medium parts, leaving just the low parts to add up at
-//     the end.
-//
-//          rs        =  sigma * r
-//          res_int   =  S_hi + rs
-//          k_0       =  S_hi - res_int
-//          k_2       =  k_0 + rs
-//          med       =  C_hl * r
-//          res_hi    =  res_int + med
-//          k_1       =  res_int - res_hi
-//          k_3       =  k_1 + med
-//
-//     6. FINAL SUMMATION
-//
-//     We now add up all the small parts:
-//
-//          res_lo = pols(hi) + pols(lo) + corr + k_1 + k_3
-//
-//     Now the overall result is just:
-//
-//          res_hi + res_lo
-//
-//     7. SMALL ARGUMENTS
-//
-//     Inputs with |X| < 2^-252 are treated specially as
-//     1 - |x|.
-//
-// Special cases:
-//  cos(NaN) = quiet NaN, and raise invalid exception
-//  cos(INF) = NaN and raise invalid exception
-//  cos(0) = 1
-//

-//                     ALGORITHM DESCRIPTION
-//                     ---------------------
-//
-// Description:
-//  Let K = 64 (table size).
-//
-//  Four sub-domains:
-//    1. |x| < 1/(2*K)
-//      expm1(x) ~ P(x)
-//    2. 1/(2*K) <= |x| <= 56*log(2)
-//       x       x/log(2)    n
-//      e - 1 = 2         = 2 * T[j] * (1 + P(y)) - 1
-//    3. 56*log(2) < x < MAX_LOG
-//       x       x   x/log(2)    n
-//      e - 1 ~ e = 2         = 2 * T[j] * (1 + P(y))
-//    4. x < -56*log(2)
-//       x            x
-//      e - 1 = -1 + e ~ -1
-//    where
-//       x = m*log(2)/K + y,    y in [-log(2)/K..log(2)/K]
-//       m = n*K + j,           m,n,j - signed integer, j in [-K/2..K/2]
-//                  j/K
-//       values of 2   are tabulated as T[j] = T_hi[j] ( 1 + T_lo[j]).
-//
-//       P(y) is a minimax polynomial approximation of exp(x)-1
-//       on small interval [-log(2)/K..log(2)/K] (were calculated by Maple V).
-//
-//    In case 3, to avoid problems with arithmetic overflow and underflow,
-//              n                        n1  n2
-//    value of 2  is safely computed as 2 * 2 where n1 in [-BIAS/2..BIAS/2]
-//    and BIAS is a value of exponent bias.
-//
-// Special cases:
-//  expm1(NaN) is NaN
-//  expm1(+INF) is +INF
-//  expm1(-INF) is -1
-//  expm1(x) is x for subnormals
-//  for finite argument, only expm1(0)=0 is exact.
-//  For IEEE double
-//    if x > 709.782712893383973096 then expm1(x) overflow
-//

-//                     ALGORITHM DESCRIPTION
-//                     ---------------------
-//
-//    Let x=2^k * mx, mx in [1,2)
-//
-//    Get B~1/mx based on the output of rcpps instruction (B0)
-//    B = int((B0*2^7+0.5))/2^7
-//
-//    Reduced argument: r=B*mx-1.0 (computed accurately in high and low parts)
-//
-//    Result:  k*log(2) - log(B) + p(r)
-//             p(r) is a degree 7 polynomial
-//             -log(B) read from data table (high, low parts)
-//             Result is formed from high and low parts
-//
-// Special cases:
-//   log1p(NaN) = quiet NaN, and raise invalid exception
-//   log1p(+INF) = that INF
-//   log1p(x) = NaN if x < -1 or x = -INF, and raises invalid exception
-//   log1p(-1) = -INF, and raises divide-by-zero exception
-//   log1p(+/-0) = +/-0
-//

-//                     ALGORITHM DESCRIPTION
-//                     ---------------------
-//
-//     1. RANGE REDUCTION
-//
-//     We perform an initial range reduction from X to r with
-//
-//          X =~= N * pi/32 + r
-//
-//     so that |r| <= pi/64 + epsilon. We restrict inputs to those
-//     where |N| <= 932560. Beyond this, the range reduction is
-//     insufficiently accurate. For extremely small inputs, 
-//     denormalization can occur internally, impacting performance.
-//     This means that the main path is actually only taken for
-//     2^-252 <= |X| < 90112.
-//
-//     To avoid branches, we perform the range reduction to full
-//     accuracy each time.
-//
-//          X - N * (P_1 + P_2 + P_3)
-//
-//     where P_1 and P_2 are 32-bit numbers (so multiplication by N
-//     is exact) and P_3 is a 53-bit number. Together, these
-//     approximate pi well enough for all cases in the restricted
-//     range.
-//
-//     The main reduction sequence is:
-//
-//             y = 32/pi * x
-//             N = integer(y)
-//     (computed by adding and subtracting off SHIFTER)
-//
-//             m_1 = N * P_1
-//             m_2 = N * P_2
-//             r_1 = x - m_1
-//             r = r_1 - m_2
-//     (this r can be used for most of the calculation)
-//
-//             c_1 = r_1 - r
-//             m_3 = N * P_3
-//             c_2 = c_1 - m_2
-//             c = c_2 - m_3
-//
-//     2. MAIN ALGORITHM
-//
-//     The algorithm uses a table lookup based on B = M * pi / 32
-//     where M = N mod 64. The stored values are:
-//       sigma             closest power of 2 to cos(B)
-//       C_hl              53-bit cos(B) - sigma
-//       S_hi + S_lo       2 * 53-bit sin(B)
-//
-//     The computation is organized as follows:
-//
-//          sin(B + r + c) = [sin(B) + sigma * r] +
-//                           r * (cos(B) - sigma) +
-//                           sin(B) * [cos(r + c) - 1] +
-//                           cos(B) * [sin(r + c) - r]
-//
-//     which is approximately:
-//
-//          [S_hi + sigma * r] +
-//          C_hl * r +
-//          S_lo + S_hi * [(cos(r) - 1) - r * c] +
-//          (C_hl + sigma) * [(sin(r) - r) + c]
-//
-//     and this is what is actually computed. We separate this sum
-//     into four parts:
-//
-//          hi + med + pols + corr
-//
-//     where
-//
-//          hi       = S_hi + sigma r
-//          med      = C_hl * r
-//          pols     = S_hi * (cos(r) - 1) + (C_hl + sigma) * (sin(r) - r)
-//          corr     = S_lo + c * ((C_hl + sigma) - S_hi * r)
-//
-//     3. POLYNOMIAL
-//
-//     The polynomial S_hi * (cos(r) - 1) + (C_hl + sigma) *
-//     (sin(r) - r) can be rearranged freely, since it is quite
-//     small, so we exploit parallelism to the fullest.
-//
-//          psc4       =   SC_4 * r_1
-//          msc4       =   psc4 * r
-//          r2         =   r * r
-//          msc2       =   SC_2 * r2
-//          r4         =   r2 * r2
-//          psc3       =   SC_3 + msc4
-//          psc1       =   SC_1 + msc2
-//          msc3       =   r4 * psc3
-//          sincospols =   psc1 + msc3
-//          pols       =   sincospols *
-//                         <S_hi * r^2 | (C_hl + sigma) * r^3>
-//
-//     4. CORRECTION TERM
-//
-//     This is where the "c" component of the range reduction is
-//     taken into account; recall that just "r" is used for most of
-//     the calculation.
-//
-//          -c   = m_3 - c_2
-//          -d   = S_hi * r - (C_hl + sigma)
-//          corr = -c * -d + S_lo
-//
-//     5. COMPENSATED SUMMATIONS
-//
-//     The two successive compensated summations add up the high
-//     and medium parts, leaving just the low parts to add up at
-//     the end.
-//
-//          rs        =  sigma * r
-//          res_int   =  S_hi + rs
-//          k_0       =  S_hi - res_int
-//          k_2       =  k_0 + rs
-//          med       =  C_hl * r
-//          res_hi    =  res_int + med
-//          k_1       =  res_int - res_hi
-//          k_3       =  k_1 + med
-//
-//     6. FINAL SUMMATION
-//
-//     We now add up all the small parts:
-//
-//          res_lo = pols(hi) + pols(lo) + corr + k_1 + k_3
-//
-//     Now the overall result is just:
-//
-//          res_hi + res_lo
-//
-//     7. SMALL ARGUMENTS
-//
-//     If |x| < SNN (SNN meaning the smallest normal number), we
-//     simply perform 0.1111111 cdots 1111 * x. For SNN <= |x|, we
-//     do 2^-55 * (2^55 * x - x).
-//
-// Special cases:
-//  sin(NaN) = quiet NaN, and raise invalid exception
-//  sin(INF) = NaN and raise invalid exception
-//  sin(+/-0) = +/-0
-//

-//                     ALGORITHM DESCRIPTION
-//                     ---------------------
-//
-// Polynomials coefficients and other constants.
-//
-// Note that in this algorithm, there is a different polynomial for
-// each breakpoint, so there are 32 sets of polynomial coefficients
-// as well as 32 instances of the other constants.
-//
-// The polynomial coefficients and constants are offset from the start
-// of the main block as follows:
-//
-//   0:  c8 | c0
-//  16:  c9 | c1
-//  32: c10 | c2
-//  48: c11 | c3
-//  64: c12 | c4
-//  80: c13 | c5
-//  96: c14 | c6
-// 112: c15 | c7
-// 128: T_hi
-// 136: T_lo
-// 144: Sigma
-// 152: T_hl
-// 160: Tau
-// 168: Mask
-// 176: (end of block)
-//
-// The total table size is therefore 5632 bytes.
-//
-// Note that c0 and c1 are always zero. We could try storing
-// other constants here, and just loading the low part of the
-// SIMD register in these cases, after ensuring the high part
-// is zero.
-//
-// The higher terms of the polynomial are computed in the *low*
-// part of the SIMD register. This is so we can overlap the
-// multiplication by r^8 and the unpacking of the other part.
-//
-// The constants are:
-// T_hi + T_lo = accurate constant term in power series
-// Sigma + T_hl = accurate coefficient of r in power series (Sigma=1 bit)
-// Tau = multiplier for the reciprocal, always -1 or 0
-//
-// The basic reconstruction formula using these constants is:
-//
-// High = tau * recip_hi + t_hi
-// Med = (sgn * r + t_hl * r)_hi
-// Low = (sgn * r + t_hl * r)_lo +
-//       tau * recip_lo + T_lo + (T_hl + sigma) * c + pol
-//
-// where pol = c0 + c1 * r + c2 * r^2 + ... + c15 * r^15
-//
-// (c0 = c1 = 0, but using them keeps SIMD regularity)
-//
-// We then do a compensated sum High + Med, add the low parts together

-//                     ALGORITHM DESCRIPTION
-//                     ---------------------
-//
-// tanh(x)=(exp(x)-exp(-x))/(exp(x)+exp(-x))=(1-exp(-2*x))/(1+exp(-2*x))
-//
-// Let |x|=xH+xL (upper 26 bits, lower 27 bits)
-// log2(e) rounded to 26 bits (high part) plus a double precision low part is
-//         L2EH+L2EL (upper 26, lower 53 bits)
-//
-// Let xH*L2EH=k+f+r`, where (k+f)*2^8*2=int(xH*L2EH*2^9),
-//                             f=0.b1 b2 ... b8, k integer
-// 2^{-f} is approximated as Tn[f]+Dn[f]
-// Tn stores the high 53 bits, Dn stores (2^{-f}-Tn[f]) rounded to double precision
-//
-//  r=r`+xL*L2EH+|x|*L2EL, |r|<2^{-9}+2^{-14},
-//                      for |x| in [23/64,3*2^7)
-// e^{-2*|x|}=2^{-k-f}*2^{-r} ~ 2^{-k}*(Tn+Dn)*(1+p)=(T0+D0)*(1+p)
-//
-// For |x| in [2^{-4},2^5):
-//         2^{-r}-1 ~ p=c1*r+c2*r^2+..+c5*r^5
-//      Let R=1/(1+T0+p*T0), truncated to 35 significant bits
-//  R=1/(1+T0+D0+p*(T0+D0))*(1+eps), |eps|<2^{-33}
-//  1+T0+D0+p*(T0+D0)=KH+KL, where
-//       KH=(1+T0+c1*r*T0)_high (leading 17 bits)
-//       KL=T0_low+D0+(c1*r*T0)_low+c1*r*D0+(c2*r^2+..c5*r^5)*T0
-//  eps ~ (R*KH-1)+R*KL
-//  1/(1+T0+D0+p*(T0+D0)) ~ R-R*eps
-//  The result is approximated as (1-T0-D0-(T0+D0)*p)*(R-R*eps)
-//  1-T0-D0-(T0+D0)*p=-((KH-2)+KL)
-//    The result is formed as
-//    (KH-2)*R+(-(KH-2)*R*eps+(KL*R-KL*R*eps)), with the correct sign
-//                                                  set at the end
-//
-// For |x| in [2^{-64},2^{-4}):
-//  A Taylor series expansion is used  (x+p3*x^3+..+p13*x^{13})
-//
-// For |x|<2^{-64}:  x is returned
-//
-// For |x|>=2^32: return +/-1
-//
-// Special cases:
-//  tanh(NaN) = quiet NaN, and raise invalid exception
-//  tanh(INF) = that INF
-//  tanh(+/-0) = +/-0

-//                     ALGORITHM DESCRIPTION
-//                     ---------------------
-//
-//  To compute acos(s), separate schemes are used when s is in different
-//  intervals.
-//
-//  |s| in [2^{-4}, sqrt(3)/2):
-//       Let t=2^k*1.b1 b2..b6 1, where s=2^k*1.b1 b2 .. b52
-//       acos(s)=pi/2-asin(t)-asin(r), where r=s*sqrt(1-t^2)-t*sqrt(1-s^2)
-//       asin(r)-r evaluated as 7-degree polynomial (c3*r^3+c5*r^5+c7*r^7)
-//       For the first degree term, r is evaluated as
-//                R=(s^2-t^2)/(sqrt(1-t^2)*s+sqrt(1-s^2)*t)
-//       (sqrt(1-t^2) read from table)
-//  The main source of error is still R (may still be affected by up to 3 ulps
-//  of rounding error). The table size must be sufficiently large, to minimize
-//  this effect.
-//
-//  |s| in [sqrt(3)/2, 255/256):
-//       Let t=2^k*1.b1 b2..b6 1, where sqrt(1-s^2)=2^k*1.b1 b2 .. b52 (rounded)
-//       acos(|s|)=asin(t)-asin(r), r=s*t-sqrt(1-s^2)*sqrt(1-t^2)
-//   acos(-|s|)=pi-acos(|s|)
-//       (The -PI constant, or 0, is added to the result. The sign is set at
-//        the end)
-//       asin(r) evaluated as a polynomial (same as above)
-//       The first degree term is evaluated as
-//                        r=(s^2+t^2-1)/(s*t+sqrt(1-s^2)*sqrt(1-t^2))
-//
-//  |s|<2^{-4}: acos(s)=pi/2-asin(s)
-//              evaluate asin(s) as 13-degree polynomial
-//
-//  |s| in [255/256,1): acos(|s|)=2*asin(q), where q=sqrt((1-|s|)/2)
-//  asin(q) is evaluated as 13-degree polynomial
-//      q^2=(1-|s|)/2 is obtained in advance
-//         2*q*eps ~ ((1-|s|)/2-q^2)/q used for first term
-//   acos(-|s|)=pi-acos(|s|)
-//       (The -PI constant, or 0, is added to the result. The sign is set at
-//        the end)
-//
-// Special cases:
-//  acos(NaN) = quiet NaN, and raise invalid exception
-//  acos(INF) = QNaN and raise invalid exception
-//  acos(x) = QNaN and raise invalid exception, for |x|>1.0
-//  acos(1) = +0

-//                     ALGORITHM DESCRIPTION
-//                     ---------------------
-//
-//  To compute asin(s), separate schemes are used when s is in different
-//  intervals.
-//
-//  |s| in [2^{-4}, sqrt(3)/2):
-//       Let t=2^k*1.b1 b2..b6 1, where s=2^k*1.b1 b2 .. b52
-//       asin(s)=asin(t)+asin(r), where r=s*sqrt(1-t^2)-t*sqrt(1-s^2)
-//       asin(r)-r evaluated as 7-degree polynomial (c3*r^3+c5*r^5+c7*r^7)
-//       For the first degree term, r is evaluated as
-//                R=(s^2-t^2)/(sqrt(1-t^2)*s+sqrt(1-s^2)*t)
-//       (sqrt(1-t^2) read from table)
-//  The main source of error is still R (may still be affected by up to 3 ulps
-//  of rounding error). The table size must be sufficiently large, to minimize
-//  this effect.
-//
-//  |s| in [sqrt(3)/2, 255/256):
-//       Let t=2^k*1.b1 b2..b6 1, where sqrt(1-s^2)=2^k*1.b1 b2 .. b52 (rounded)
-//       asin(|s|)=pi/2-asin(t)+asin(r), r=s*t-sqrt(1-s^2)*sqrt(1-t^2)
-//       asin(r) evaluated as polynomial (same as above)
-//       The first degree term is evaluated as
-//                        r=(s^2+t^2-1)/(s*t+sqrt(1-s^2)*sqrt(1-t^2))
-//
-//  |s|<2^{-4}: evaluate as 13-degree polynomial
-//
-//  |s| in [255/256,1): asin(|s|)=pi/2-asin(sqrt(1-s^2))
-//         use 17-degree polynomial, get error term
-//         Q*eps ~ (1-s^2-Q^2)/(2*Q) for first term
-//                 ( Q(1+eps)=sqrt(1-s^2) )
-//
-// Special cases:
-//  asin(NaN) = quiet NaN, and raise invalid exception
-//  asin(INF) = QNaN and raise invalid exception
-//  asin(x) = QNaN and raise invalid exception, for |x|>1.0
-//  asin(+/-0) = +/-0

-//                     ---------------------
-//
-//
-//1. The method is based on the relationship of atan2(Y,X) to atan(|Y/X|)
-//   as follows.
-//                   /  sign(Y) atan(|Y/X|)                if X > 0
-//       atan2(Y,X) =
-//                   \  sign(Y)*pi  - sign(Y)*atan(|Y/X|)  if X < 0
-//
-//   Thus, atan2(Y,X) is of the form  atan2(Y,X) = PI + sgn*atan(|Y/X|)
-//   where PI and sgn can be determined by the four possible combinations of
-//   of the pair (sign(X),sign(Y)). We concentrate on the numerical method
-//   for atan(|Y/X|).
-//
-//2. For |Y/X| < 2^(-64), atan(|Y/X|) ~=~ |Y/X|. Hence, atan2(Y,X) is  Y/X
-//   if X > 0, and sign(Y)*pi otherwise.
-//3. For |Y/X| >= 2^(65), atan(|Y/X|) ~=~ pi/2. Hence atan2(Y,X) is sign(Y)pi/2.
-//4. For 2^(-64) <= |Y/X| < 2^(-5), atan(|Y/X|) is approximated by a polynomial
-//   of the form  Z + Z*E*polynomial(E), where Z = |Y/X| and E = Z*Z.
-//5. For |Y/X| > 2^(5), atan(|Y/X|) = pi/2 + atan(-|X/Y|), and atan(-|X/Y|) is
-//   calculated using the polynomial in 4 above.
-//6. For 2^(-5) <= |Y/X| <= 2^(5), we employ a table lookup method. First,
-//   we obtain B = 2^k * 1.b1 b2 b3 b4 = 2^k * (1+k/16) that approximate
-//   |Y/X| to approximately 5 significant bits. Hence, atan(|Y/X|) is
-//
-//      atan(|Y/X|)  =  atan(B) + atan(Z), where  Z = (|Y|-B|X|)/(|X|+B|Y|).
-//                  ~=~   tau   + Z + Z*E*polynomial(E), where E = Z*Z.
-//
-//   B has the range from 2^(-6)*(1+14/16) to 2^5 = 2^(5)*(1+0/16), totally
-//   163 possible values. These values are calculated beforehand and stored
-//   in a table. The polynomial is the one used in 4.
-//
-// Special cases:
-//  atan2(+-0, +0) = +-0
-//  atan2(+-0, -0) = +-pi
-//  atan2(+-0, x) = +-0, for x > 0, and +-pi, for x < 0
-//  atan2(y, +-0) = +pi/2 for y > 0, and -pi/2 for y < 0
-//  atan2(+-y, +INF) = +-0, for finite y > 0
-//  atan2(+-y, -INF) = +-pi, for finite y > 0
-//  atan2(+-INF, x) = +-pi/2, for finite x
-//  atan2(+-INF, +INF) = +-pi/4
-//  atan2(+-INF, -INF) = +-3*pi/4

-//                     ALGORITHM DESCRIPTION
-//                     ---------------------
-//
-//  cosh(x)=(exp(x)+exp(-x))/2
-//
-//  Let |x|=xH+xL (upper 26 bits, lower 27 bits)
-//  log2(e) rounded to 26 bits (high part) plus a double precision low part is
-//          L2EH+L2EL (upper 26, lower 53 bits)
-//
-//  Let xH*L2EH=k+f+r`, where (k+f)*2^7=int(xH*L2EH*2^7),
-//                              f=0.b1 b2 ... b7, k integer
-//  2^f is approximated as Tp[f]+Dp[f], and 2^{-f} as Tn[f]+Dn[f]
-//  Tp stores higher 53 bits, Dp stores (2^f-Tp[f]) rounded to double precision
-//
-//  e^|x|=2^{k+f}*2^r, r=r`+xL*L2EH+|x|*L2EL, |r|<2^{-8}+2^{-14},
-//                       for |x| in [1/8,3*2^8)
-//  e^{-|x|}=2^{-k-f}*2^{-r}
-//
-//  e^|x| is approximated as 2^k*Tp+2^k*Tp*c1*r(1+c2*r+..+c5*r^4)+2^k*Dp=
-//                           =2^k*Tp+2^k*Tp*P15+2^k*Dp
-//  e^{-|x|} approximated as 2^{-k}*Tn-2^{-k}*Tn*c1*r(1-c2*r+..+c5*r^4)
-//
-//  For |x| in [1/8, 3*2^7), cosh(x) is formed as
-//   RN(2^k*Tp+2^{-k}*Tn)+2^k*Tp*P15+2^{-k}*Tn*P`15+2^{-k}*TnL+2^{-k}*Dn+2^k*Dp
-//
-//  For |x| in [3*2^7, 3*2^8), (e^|x|)/2 is returned, and
-//  the result is checked for overflow.
-//
-//  For |x|<1/8, a Taylor polynomial expansion is used (degree 10)
-//  (error bound for polynomial expansion is below 0.501 ulp)
-//
-// Special cases:
-//  cosh(NaN) = quiet NaN, and raise invalid exception
-//  cosh(INF) = that INF
-//  cosh(0)=1
-//  for finite argument, only cosh(0)=1 is exact
-//  For IEEE double
-//  cosh(x) overflows
-//  for x > 710.47586007394386342639336362481117248535156250 = MAXLOG+log(2)

-//                     ALGORITHM DESCRIPTION
-//                     ---------------------
-//
-// X87 version:
-// Use 80-bit FPU precision fmul, fsqrt to compute square and sqrt.
-//
-// SSE version:
-// Swap x, y if |x|<|y|
-// For x=2^k*x, get y=y*2^(-k)
-// Get S ~ sqrt(x^2+y^2)  (leading 1 + leading 25 mantissa bits)
-//
-// Get D = ( RN(x^2+y^2) - S^2 ) + ( x^2 - RN(x^2) ) +
-//                               + ( y^2 - ((RN(x^2+y^2)-RN(x^2)) )
-//
-// Result is 2^k*(S + Se),  where Se = S*e
-//        S*e is approximated as (D/2S)*( 1 - (D/2S)^2*1.0/S )
-//
-// Return 2^k*(S+Se)
-//
-// For |y/x|<2^(-64), return x
-//
-// For cases where maximum biased exponent is either greater than 7fdh or
-// below 32, take a special path to check for special cases (0, NaN, Inf),
-// possible overflow, and more accurate computation for denormal results
-//
-// Special cases:
-//  hypot(x,y), hypot(y,x), and hypot(x,-y) are equivalent
-//  hypot(x,+-0) is equivalent to fabs(x)
-//  hypot(x,y) = y if (x==NaN or x==INF) and y==INF
-//  hypot(x,y) = x if (x==NaN or x==INF) and y!=INF (even if y==NaN!)
-//  hypot(x,y) = y if (x!=NaN and x!=INF) and (y==NaN or y==INF)
-//

-//                     ALGORITHM DESCRIPTION
-//                     ---------------------
-//
-//    Let x=2^k * mx, mx in [1,2)
-//
-//    Get B~1/mx based on the output of rcpss instruction (B0)
-//    B = int((B0*LH*2^7+0.5))/2^7
-//    LH is a short approximation for log10(e)
-//
-//    Reduced argument: r=B*mx-LH (computed accurately in high and low parts)
-//
-//    Result:  k*log10(2) - log(B) + p(r)
-//             p(r) is a degree 7 polynomial
-//             -log(B) read from data table (high, low parts)
-//             Result is formed from high and low parts
-//
-// Special cases:
-//  log10(0) = -INF with divide-by-zero exception raised                                           
-//  log10(1) = +0
-//  log10(x) = NaN with invalid exception raised if x < -0, including -INF
-//  log10(+INF) = +INF
-//

-//                     ALGORITHM DESCRIPTION
-//                     ---------------------
-//
-//  sinh(x)=(exp(x)-exp(-x))/2
-//
-//  Let |x|=xH+xL (upper 26 bits, lower 27 bits)
-//  log2(e) rounded to 26 bits (high part) plus a double precision low part is
-//          L2EH+L2EL (upper 26, lower 53 bits)
-//
-//  Let xH*L2EH=k+f+r`, where (k+f)*2^7=int(xH*L2EH*2^7),
-//                              f=0.b1 b2 ... b7, k integer
-//  2^f is approximated as Tp[f]+Dp[f], and 2^{-f} as Tn[f]+Dn[f]
-//  Tp stores the high 53 bits, Dp stores (2^f-Tp[f]) rounded to double precision
-//
-//  e^|x|=2^{k+f}*2^r, r=r`+xL*L2EH+|x|*L2EL, |r|<2^{-8}+2^{-14},
-//                       for |x| in [23/64,3*2^7)
-//  e^{-|x|}=2^{-k-f}*2^{-r}
-//
-//  e^|x| is approximated as 2^k*Tp+2^k*Tp*c1*r(1+c2*r+..+c5*r^4)+2^k*Dp=
-//                           =2^k*Tp+2^k*Tp*P15+2^k*Dp
-//  e^{-|x|} approximated as 2^{-k}*Tn-2^{-k}*Tn*c1*r(1-c2*r+..+c5*r^4)+2^{-k}*Dn
-//
-//  For |x| in [1/8, 3*2^7), sinh(x) is formed as
-//      RN(2^k*Tp-2^{-k}*Tn)+2^k*Tp*P15-2^{-k}*Tn*P`15-2^{-k}*TnL-2^{-k}*Dn+2^k*Dp
-//
-//  For x in (3*2^7, 3*2^8), sign(x)*(e^|x|)/2 is returned, and
-//  the result is checked for overflow.
-//
-//  For |x|<23/64, a Taylor polynomial expansion is used (degree 13)
-//  To reduce rounding errors, the p3*x^3 term is computed as
-//     (p3*xh^3)_high+[(p3*xl*(3*x*xh+xl^2))+(p3*xh^3)_low],
-//  where x=xh+xl, (xh are the leading 17 bits of x), and
-//     (p3*xh^3)_high=RN(x+p3*xh^3)-x
-//  (error bound for polynomial expansion is below 0.51 ulp)
-//
-// Special cases:
-//  sinh(NaN) = quiet NaN, and raise invalid exception
-//  sinh(+/-INF) = +/-INF
-//  sinh(x) = x for subnormals
-//  for finite argument, only sinh(0)=0 is exact
-//  For IEEE double
-//    sinh(x) overflows  for x > 
-//    710.47586007394386342639336362481117248535156250 = MAXLOG+log(2)

-//                     ALGORITHM DESCRIPTION
-//                     ---------------------
-//
-// This implementation uses the main path for |x| in [2^{-5},2^65).
-// For |x| in [2^{-64},2^{-5}), a secondary path is used.
-// For the biased exponent of X within 3FFH-64 and 3FF+64, we use one branch.
-// We use the following definition of B and X` so that the formula
-// atan(X) = Tau + atan( (X`-B) / (One + BX) ) is correct
-//
-// X = (-1)^s * 2^k * 1. x1 x2 ... x52
-//
-// Define X`  = 0 if k >= 5; and X`  = |X| otherwise
-// Define One = 0 if k >= 5; and One = 1 otherwise
-// Define B  = 0 if k <= -6; B =  2^k * 1.x1 x2 x3 x4 1  if -5 <= k <= 4
-// Define B  =  2^5 * 1.0 0 ... 0   if  k >= 5
-//
-// Tau is 0 if k <= -6;
-// Tau is atan( B )  if -5 <= k <= 4
-// Tau is pi/2 if k >= 5
-//
-// Special cases:
-//  atan(NaN) = quiet NaN
-//  atan(+/-INF) = +/-Pi/2
-//  atan(+/-0) = +/-0
-//

-//                     ALGORITHM DESCRIPTION
-//                     ---------------------
-//
-//   Assume x=2^{3*k+j} * 1.b1 b2 ... b5 b6 ... b52, where j = 0,1,2.
-//   Let r=(x*2^{-3k-j} - 1.b1 b2 ... b5 1)* rcp[b1 b2 ..b5],
-//   where rcp[b1 b2 .. b5]=1/(1.b1 b2 b3 b4 b5 1) in double precision
-//   cbrt(2^j * 1. b1 b2 .. b5 1) is approximated as T[j][b1..b5]+D[j][b1..b5]
-//   (T stores the high 53 bits, D stores the low order bits)
-//   Result=2^k*T+(2^k*T*r)*P+2^k*D
-//   where P=p1+p2*r+..+p8*r^7
-//
-// Special cases:
-//  cbrt(NaN) = quiet NaN, and raise invalid exception
-//  cbrt(INF) = that INF
-//  cbrt(+/-0) = +/-0
-//

-//                     ALGORITHM DESCRIPTION
-//                     ---------------------
-//
-//     1. RANGE REDUCTION
-//
-//     We perform an initial range reduction from X to r with
-//
-//          X =~= N * pi/32 + r
-//
-//     so that |r| <= pi/64 + epsilon. We restrict inputs to those
-//     where |N| <= 932560. Beyond this, the range reduction is
-//     insufficiently accurate. For extremely small inputs, 
-//     denormalization can occur internally, impacting performance.
-//     This means that the main path is actually only taken for
-//     2^-252 <= |X| < 90112.
-//
-//     To avoid branches, we perform the range reduction to full
-//     accuracy each time.
-//
-//          X - N * (P_1 + P_2 + P_3)
-//
-//     where P_1 and P_2 are 32-bit numbers (so multiplication by N
-//     is exact) and P_3 is a 53-bit number. Together, these
-//     approximate pi well enough for all cases in the restricted
-//     range.
-//
-//     The main reduction sequence is:
-//
-//             y = 32/pi * x
-//             N = integer(y)
-//     (computed by adding and subtracting off SHIFTER)
-//
-//             m_1 = N * P_1
-//             m_2 = N * P_2
-//             r_1 = x - m_1
-//             r = r_1 - m_2
-//     (this r can be used for most of the calculation)
-//
-//             c_1 = r_1 - r
-//             m_3 = N * P_3
-//             c_2 = c_1 - m_2
-//             c = c_2 - m_3
-//
-//     2. MAIN ALGORITHM
-//
-//     The algorithm uses a table lookup based on B = M * pi / 32
-//     where M = N mod 64. The stored values are:
-//       sigma             closest power of 2 to cos(B)
-//       C_hl              53-bit cos(B) - sigma
-//       S_hi + S_lo       2 * 53-bit sin(B)
-//
-//     The computation is organized as follows:
-//
-//          sin(B + r + c) = [sin(B) + sigma * r] +
-//                           r * (cos(B) - sigma) +
-//                           sin(B) * [cos(r + c) - 1] +
-//                           cos(B) * [sin(r + c) - r]
-//
-//     which is approximately:
-//
-//          [S_hi + sigma * r] +
-//          C_hl * r +
-//          S_lo + S_hi * [(cos(r) - 1) - r * c] +
-//          (C_hl + sigma) * [(sin(r) - r) + c]
-//
-//     and this is what is actually computed. We separate this sum
-//     into four parts:
-//
-//          hi + med + pols + corr
-//
-//     where
-//
-//          hi       = S_hi + sigma r
-//          med      = C_hl * r
-//          pols     = S_hi * (cos(r) - 1) + (C_hl + sigma) * (sin(r) - r)
-//          corr     = S_lo + c * ((C_hl + sigma) - S_hi * r)
-//
-//     3. POLYNOMIAL
-//
-//     The polynomial S_hi * (cos(r) - 1) + (C_hl + sigma) *
-//     (sin(r) - r) can be rearranged freely, since it is quite
-//     small, so we exploit parallelism to the fullest.
-//
-//          psc4       =   SC_4 * r_1
-//          msc4       =   psc4 * r
-//          r2         =   r * r
-//          msc2       =   SC_2 * r2
-//          r4         =   r2 * r2
-//          psc3       =   SC_3 + msc4
-//          psc1       =   SC_1 + msc2
-//          msc3       =   r4 * psc3
-//          sincospols =   psc1 + msc3
-//          pols       =   sincospols *
-//                         <S_hi * r^2 | (C_hl + sigma) * r^3>
-//
-//     4. CORRECTION TERM
-//
-//     This is where the "c" component of the range reduction is
-//     taken into account; recall that just "r" is used for most of
-//     the calculation.
-//
-//          -c   = m_3 - c_2
-//          -d   = S_hi * r - (C_hl + sigma)
-//          corr = -c * -d + S_lo
-//
-//     5. COMPENSATED SUMMATIONS
-//
-//     The two successive compensated summations add up the high
-//     and medium parts, leaving just the low parts to add up at
-//     the end.
-//
-//          rs        =  sigma * r
-//          res_int   =  S_hi + rs
-//          k_0       =  S_hi - res_int
-//          k_2       =  k_0 + rs
-//          med       =  C_hl * r
-//          res_hi    =  res_int + med
-//          k_1       =  res_int - res_hi
-//          k_3       =  k_1 + med
-//
-//     6. FINAL SUMMATION
-//
-//     We now add up all the small parts:
-//
-//          res_lo = pols(hi) + pols(lo) + corr + k_1 + k_3
-//
-//     Now the overall result is just:
-//
-//          res_hi + res_lo
-//
-//     7. SMALL ARGUMENTS
-//
-//     Inputs with |X| < 2^-252 are treated specially as
-//     1 - |x|.
-//
-// Special cases:
-//  cos(NaN) = quiet NaN, and raise invalid exception
-//  cos(INF) = NaN and raise invalid exception
-//  cos(0) = 1
-//

-//                     ALGORITHM DESCRIPTION
-//                     ---------------------
-//
-// Description:
-//  Let K = 64 (table size).
-//
-//  Four sub-domains:
-//    1. |x| < 1/(2*K)
-//      expm1(x) ~ P(x)
-//    2. 1/(2*K) <= |x| <= 56*log(2)
-//       x       x/log(2)    n
-//      e - 1 = 2         = 2 * T[j] * (1 + P(y)) - 1
-//    3. 56*log(2) < x < MAX_LOG
-//       x       x   x/log(2)    n
-//      e - 1 ~ e = 2         = 2 * T[j] * (1 + P(y))
-//    4. x < -56*log(2)
-//       x            x
-//      e - 1 = -1 + e ~ -1
-//    where
-//       x = m*log(2)/K + y,    y in [-log(2)/K..log(2)/K]
-//       m = n*K + j,           m,n,j - signed integer, j in [-K/2..K/2]
-//                  j/K
-//       values of 2   are tabulated as T[j] = T_hi[j] ( 1 + T_lo[j]).
-//
-//       P(y) is a minimax polynomial approximation of exp(x)-1
-//       on small interval [-log(2)/K..log(2)/K] (were calculated by Maple V).
-//
-//    In case 3, to avoid problems with arithmetic overflow and underflow,
-//              n                        n1  n2
-//    value of 2  is safely computed as 2 * 2 where n1 in [-BIAS/2..BIAS/2]
-//    and BIAS is a value of exponent bias.
-//
-// Special cases:
-//  expm1(NaN) is NaN
-//  expm1(+INF) is +INF
-//  expm1(-INF) is -1
-//  expm1(x) is x for subnormals
-//  for finite argument, only expm1(0)=0 is exact.
-//  For IEEE double
-//    if x > 709.782712893383973096 then expm1(x) overflow
-//

-//                     ALGORITHM DESCRIPTION
-//                     ---------------------
-//
-//    Let x=2^k * mx, mx in [1,2)
-//
-//    Get B~1/mx based on the output of rcpps instruction (B0)
-//    B = int((B0*2^7+0.5))/2^7
-//
-//    Reduced argument: r=B*mx-1.0 (computed accurately in high and low parts)
-//
-//    Result:  k*log(2) - log(B) + p(r)
-//             p(r) is a degree 7 polynomial
-//             -log(B) read from data table (high, low parts)
-//             Result is formed from high and low parts
-//
-// Special cases:
-//   log1p(NaN) = quiet NaN, and raise invalid exception
-//   log1p(+INF) = that INF
-//   log1p(x) = NaN if x < -1 or x = -INF, and raises invalid exception
-//   log1p(-1) = -INF, and raises divide-by-zero exception
-//   log1p(+/-0) = +/-0
-//

-//                     ALGORITHM DESCRIPTION
-//                     ---------------------
-//
-//     1. RANGE REDUCTION
-//
-//     We perform an initial range reduction from X to r with
-//
-//          X =~= N * pi/32 + r
-//
-//     so that |r| <= pi/64 + epsilon. We restrict inputs to those
-//     where |N| <= 932560. Beyond this, the range reduction is
-//     insufficiently accurate. For extremely small inputs, 
-//     denormalization can occur internally, impacting performance.
-//     This means that the main path is actually only taken for
-//     2^-252 <= |X| < 90112.
-//
-//     To avoid branches, we perform the range reduction to full
-//     accuracy each time.
-//
-//          X - N * (P_1 + P_2 + P_3)
-//
-//     where P_1 and P_2 are 32-bit numbers (so multiplication by N
-//     is exact) and P_3 is a 53-bit number. Together, these
-//     approximate pi well enough for all cases in the restricted
-//     range.
-//
-//     The main reduction sequence is:
-//
-//             y = 32/pi * x
-//             N = integer(y)
-//     (computed by adding and subtracting off SHIFTER)
-//
-//             m_1 = N * P_1
-//             m_2 = N * P_2
-//             r_1 = x - m_1
-//             r = r_1 - m_2
-//     (this r can be used for most of the calculation)
-//
-//             c_1 = r_1 - r
-//             m_3 = N * P_3
-//             c_2 = c_1 - m_2
-//             c = c_2 - m_3
-//
-//     2. MAIN ALGORITHM
-//
-//     The algorithm uses a table lookup based on B = M * pi / 32
-//     where M = N mod 64. The stored values are:
-//       sigma             closest power of 2 to cos(B)
-//       C_hl              53-bit cos(B) - sigma
-//       S_hi + S_lo       2 * 53-bit sin(B)
-//
-//     The computation is organized as follows:
-//
-//          sin(B + r + c) = [sin(B) + sigma * r] +
-//                           r * (cos(B) - sigma) +
-//                           sin(B) * [cos(r + c) - 1] +
-//                           cos(B) * [sin(r + c) - r]
-//
-//     which is approximately:
-//
-//          [S_hi + sigma * r] +
-//          C_hl * r +
-//          S_lo + S_hi * [(cos(r) - 1) - r * c] +
-//          (C_hl + sigma) * [(sin(r) - r) + c]
-//
-//     and this is what is actually computed. We separate this sum
-//     into four parts:
-//
-//          hi + med + pols + corr
-//
-//     where
-//
-//          hi       = S_hi + sigma r
-//          med      = C_hl * r
-//          pols     = S_hi * (cos(r) - 1) + (C_hl + sigma) * (sin(r) - r)
-//          corr     = S_lo + c * ((C_hl + sigma) - S_hi * r)
-//
-//     3. POLYNOMIAL
-//
-//     The polynomial S_hi * (cos(r) - 1) + (C_hl + sigma) *
-//     (sin(r) - r) can be rearranged freely, since it is quite
-//     small, so we exploit parallelism to the fullest.
-//
-//          psc4       =   SC_4 * r_1
-//          msc4       =   psc4 * r
-//          r2         =   r * r
-//          msc2       =   SC_2 * r2
-//          r4         =   r2 * r2
-//          psc3       =   SC_3 + msc4
-//          psc1       =   SC_1 + msc2
-//          msc3       =   r4 * psc3
-//          sincospols =   psc1 + msc3
-//          pols       =   sincospols *
-//                         <S_hi * r^2 | (C_hl + sigma) * r^3>
-//
-//     4. CORRECTION TERM
-//
-//     This is where the "c" component of the range reduction is
-//     taken into account; recall that just "r" is used for most of
-//     the calculation.
-//
-//          -c   = m_3 - c_2
-//          -d   = S_hi * r - (C_hl + sigma)
-//          corr = -c * -d + S_lo
-//
-//     5. COMPENSATED SUMMATIONS
-//
-//     The two successive compensated summations add up the high
-//     and medium parts, leaving just the low parts to add up at
-//     the end.
-//
-//          rs        =  sigma * r
-//          res_int   =  S_hi + rs
-//          k_0       =  S_hi - res_int
-//          k_2       =  k_0 + rs
-//          med       =  C_hl * r
-//          res_hi    =  res_int + med
-//          k_1       =  res_int - res_hi
-//          k_3       =  k_1 + med
-//
-//     6. FINAL SUMMATION
-//
-//     We now add up all the small parts:
-//
-//          res_lo = pols(hi) + pols(lo) + corr + k_1 + k_3
-//
-//     Now the overall result is just:
-//
-//          res_hi + res_lo
-//
-//     7. SMALL ARGUMENTS
-//
-//     If |x| < SNN (SNN meaning the smallest normal number), we
-//     simply perform 0.1111111 cdots 1111 * x. For SNN <= |x|, we
-//     do 2^-55 * (2^55 * x - x).
-//
-// Special cases:
-//  sin(NaN) = quiet NaN, and raise invalid exception
-//  sin(INF) = NaN and raise invalid exception
-//  sin(+/-0) = +/-0
-//

-//                     ALGORITHM DESCRIPTION
-//                     ---------------------
-//
-// Polynomials coefficients and other constants.
-//
-// Note that in this algorithm, there is a different polynomial for
-// each breakpoint, so there are 32 sets of polynomial coefficients
-// as well as 32 instances of the other constants.
-//
-// The polynomial coefficients and constants are offset from the start
-// of the main block as follows:
-//
-//   0:  c8 | c0
-//  16:  c9 | c1
-//  32: c10 | c2
-//  48: c11 | c3
-//  64: c12 | c4
-//  80: c13 | c5
-//  96: c14 | c6
-// 112: c15 | c7
-// 128: T_hi
-// 136: T_lo
-// 144: Sigma
-// 152: T_hl
-// 160: Tau
-// 168: Mask
-// 176: (end of block)
-//
-// The total table size is therefore 5632 bytes.
-//
-// Note that c0 and c1 are always zero. We could try storing
-// other constants here, and just loading the low part of the
-// SIMD register in these cases, after ensuring the high part
-// is zero.
-//
-// The higher terms of the polynomial are computed in the *low*
-// part of the SIMD register. This is so we can overlap the
-// multiplication by r^8 and the unpacking of the other part.
-//
-// The constants are:
-// T_hi + T_lo = accurate constant term in power series
-// Sigma + T_hl = accurate coefficient of r in power series (Sigma=1 bit)
-// Tau = multiplier for the reciprocal, always -1 or 0
-//
-// The basic reconstruction formula using these constants is:
-//
-// High = tau * recip_hi + t_hi
-// Med = (sgn * r + t_hl * r)_hi
-// Low = (sgn * r + t_hl * r)_lo +
-//       tau * recip_lo + T_lo + (T_hl + sigma) * c + pol
-//
-// where pol = c0 + c1 * r + c2 * r^2 + ... + c15 * r^15
-//
-// (c0 = c1 = 0, but using them keeps SIMD regularity)
-//
-// We then do a compensated sum High + Med, add the low parts together
-// and then do the final sum.
-//
-// Here recip_hi + recip_lo is an accurate reciprocal of the remainder
-// modulo pi/2
-//
-// Special cases:
-//  tan(NaN) = quiet NaN, and raise invalid exception
-//  tan(INF) = NaN and raise invalid exception
-//  tan(+/-0) = +/-0
-//

-//                     ALGORITHM DESCRIPTION
-//                     ---------------------
-//
-// tanh(x)=(exp(x)-exp(-x))/(exp(x)+exp(-x))=(1-exp(-2*x))/(1+exp(-2*x))
-//
-// Let |x|=xH+xL (upper 26 bits, lower 27 bits)
-// log2(e) rounded to 26 bits (high part) plus a double precision low part is
-//         L2EH+L2EL (upper 26, lower 53 bits)
-//
-// Let xH*L2EH=k+f+r`, where (k+f)*2^8*2=int(xH*L2EH*2^9),
-//                             f=0.b1 b2 ... b8, k integer
-// 2^{-f} is approximated as Tn[f]+Dn[f]
-// Tn stores the high 53 bits, Dn stores (2^{-f}-Tn[f]) rounded to double precision
-//
-//  r=r`+xL*L2EH+|x|*L2EL, |r|<2^{-9}+2^{-14},
-//                      for |x| in [23/64,3*2^7)
-// e^{-2*|x|}=2^{-k-f}*2^{-r} ~ 2^{-k}*(Tn+Dn)*(1+p)=(T0+D0)*(1+p)
-//
-// For |x| in [2^{-4},2^5):
-//         2^{-r}-1 ~ p=c1*r+c2*r^2+..+c5*r^5
-//      Let R=1/(1+T0+p*T0), truncated to 35 significant bits
-//  R=1/(1+T0+D0+p*(T0+D0))*(1+eps), |eps|<2^{-33}
-//  1+T0+D0+p*(T0+D0)=KH+KL, where
-//       KH=(1+T0+c1*r*T0)_high (leading 17 bits)
-//       KL=T0_low+D0+(c1*r*T0)_low+c1*r*D0+(c2*r^2+..c5*r^5)*T0
-//  eps ~ (R*KH-1)+R*KL
-//  1/(1+T0+D0+p*(T0+D0)) ~ R-R*eps
-//  The result is approximated as (1-T0-D0-(T0+D0)*p)*(R-R*eps)
-//  1-T0-D0-(T0+D0)*p=-((KH-2)+KL)
-//    The result is formed as
-//    (KH-2)*R+(-(KH-2)*R*eps+(KL*R-KL*R*eps)), with the correct sign
-//                                                  set at the end
-//
-// For |x| in [2^{-64},2^{-4}):
-//  A Taylor series expansion is used  (x+p3*x^3+..+p13*x^{13})
-//
-// For |x|<2^{-64}:  x is returned
-//
-// For |x|>=2^32: return +/-1
-//
-// Special cases:
-//  tanh(NaN) = quiet NaN, and raise invalid exception
-//  tanh(INF) = that INF
-//  tanh(+/-0) = +/-0
