-// =================================================================================================
-// WIP - see http://b/177892522 for details
-//
-// The build support for boot images is currently being migrated away from singleton to modules so
-// the documentation may not be strictly accurate. Rather than update the documentation at every
-// step which will create a lot of churn the changes that have been made will be listed here and the
-// documentation will be updated once it is closer to the final result.
-//
-// Changes:
-// 1) dex_bootjars is now a singleton module and not a plain singleton.
-// 2) Boot images are now represented by the boot_image module type.
-// 3) The art boot image is called "art-boot-image", the framework boot image is called
-//    "framework-boot-image".
-// 4) They are defined in art/build/boot/Android.bp and frameworks/base/boot/Android.bp
-//    respectively.
-// 5) Each boot_image retrieves the appropriate boot image configuration from the map returned by
-//    genBootImageConfigs() using the image_name specified in the boot_image module.
-// =================================================================================================
-
-// This comment describes:
-//   1. ART boot images in general (their types, structure, file layout, etc.)
-//   2. build system support for boot images
-//
-// 1. ART boot images
-// ------------------
-//
-// A boot image in ART is a set of files that contain AOT-compiled native code and a heap snapshot
-// of AOT-initialized classes for the bootclasspath Java libraries. A boot image is compiled from a
-// set of DEX jars by the dex2oat compiler. A boot image is used for two purposes: 1) it is
-// installed on device and loaded at runtime, and 2) other Java libraries and apps are compiled
-// against it (compilation may take place either on host, known as "dexpreopt", or on device, known
-// as "dexopt").
-//
-// A boot image is not a single file, but a collection of interrelated files. Each boot image has a
-// number of components that correspond to the Java libraries that constitute it. For each component
-// there are multiple files:
-//   - *.oat or *.odex file with native code (architecture-specific, one per instruction set)
-//   - *.art file with pre-initialized Java classes (architecture-specific, one per instruction set)
-//   - *.vdex file with verification metadata for the DEX bytecode (architecture independent)
-//
-// *.vdex files for the boot images do not contain the DEX bytecode itself, because the
-// bootclasspath DEX files are stored on disk in uncompressed and aligned form. Consequently a boot
-// image is not self-contained and cannot be used without its DEX files. To simplify the management
-// of boot image files, ART uses a certain naming scheme and associates the following metadata with
-// each boot image:
-//   - A stem, which is a symbolic name that is prepended to boot image file names.
-//   - A location (on-device path to the boot image files).
-//   - A list of boot image locations (on-device paths to dependency boot images).
-//   - A set of DEX locations (on-device paths to the DEX files, one location for one DEX file used
-//     to compile the boot image).
-//
-// There are two kinds of boot images:
-//   - primary boot images
-//   - boot image extensions
-//
-// 1.1. Primary boot images
-// ------------------------
-//
-// A primary boot image is compiled for a core subset of bootclasspath Java libraries. It does not
-// depend on any other images, and other boot images may depend on it.
-//
-// For example, assuming that the stem is "boot", the location is /apex/com.android.art/javalib/,
-// the set of core bootclasspath libraries is A B C, and the boot image is compiled for ARM targets
-// (32 and 64 bits), it will have three components with the following files:
-//   - /apex/com.android.art/javalib/{arm,arm64}/boot.{art,oat,vdex}
-//   - /apex/com.android.art/javalib/{arm,arm64}/boot-B.{art,oat,vdex}
-//   - /apex/com.android.art/javalib/{arm,arm64}/boot-C.{art,oat,vdex}
-//
-// The files of the first component are special: they do not have the component name appended after
-// the stem. This naming convention dates back to the times when the boot image was not split into
-// components, and there were just boot.oat and boot.art. The decision to split was motivated by
-// licensing reasons for one of the bootclasspath libraries.
-//
-// As of November 2020 the only primary boot image in Android is the image in the ART APEX
-// com.android.art. The primary ART boot image contains the Core libraries that are part of the ART
-// module. When the ART module gets updated, the primary boot image will be updated with it, and all
-// dependent images will get invalidated (the checksum of the primary image stored in dependent
-// images will not match), unless they are updated in sync with the ART module.
-//
-// 1.2. Boot image extensions
-// --------------------------
-//
-// A boot image extension is compiled for a subset of bootclasspath Java libraries (in particular,
-// this subset does not include the Core bootclasspath libraries that go into the primary boot
-// image). A boot image extension depends on the primary boot image and optionally some other boot
-// image extensions. Other images may depend on it. In other words, boot image extensions can form
-// acyclic dependency graphs.
-//
-// The motivation for boot image extensions comes from the Mainline project. Consider a situation
-// when the list of bootclasspath libraries is A B C, and both A and B are parts of the Android
-// platform, but C is part of an updatable APEX com.android.C. When the APEX is updated, the Java
-// code for C might have changed compared to the code that was used to compile the boot image.
-// Consequently, the whole boot image is obsolete and invalidated (even though the code for A and B
-// that does not depend on C is up to date). To avoid this, the original monolithic boot image is
-// split in two parts: the primary boot image that contains A B, and the boot image extension that
-// contains C and depends on the primary boot image (extends it).
-//
-// For example, assuming that the stem is "boot", the location is /system/framework, the set of
-// bootclasspath libraries is D E (where D is part of the platform and is located in
-// /system/framework, and E is part of a non-updatable APEX com.android.E and is located in
-// /apex/com.android.E/javalib), and the boot image is compiled for ARM targets (32 and 64 bits),
-// it will have two components with the following files:
-//   - /system/framework/{arm,arm64}/boot-D.{art,oat,vdex}
-//   - /system/framework/{arm,arm64}/boot-E.{art,oat,vdex}
-//
-// As of November 2020 the only boot image extension in Android is the Framework boot image
-// extension. It extends the primary ART boot image and contains Framework libraries and other
-// bootclasspath libraries from the platform and non-updatable APEXes that are not included in the
-// ART image. The Framework boot image extension is updated together with the platform. In the
-// future other boot image extensions may be added for some updatable modules.
-//
-//
-// 2. Build system support for boot images
-// ---------------------------------------
-//
-// The primary ART boot image needs to be compiled with one dex2oat invocation that depends on DEX
-// jars for the core libraries. Framework boot image extension needs to be compiled with one dex2oat
-// invocation that depends on the primary ART boot image and all bootclasspath DEX jars except the
-// core libraries as they are already part of the primary ART boot image.
-//
-// 2.1. Libraries that go in the boot images
-// -----------------------------------------
-//
-// The contents of each boot image are determined by the PRODUCT variables. The primary ART APEX
-// boot image contains libraries listed in the ART_APEX_JARS variable in the AOSP makefiles. The
-// Framework boot image extension contains libraries specified in the PRODUCT_BOOT_JARS and
-// PRODUCT_BOOT_JARS_EXTRA variables. The AOSP makefiles specify some common Framework libraries,
-// but more product-specific libraries can be added in the product makefiles.
-//
-// Each component of the PRODUCT_BOOT_JARS and PRODUCT_BOOT_JARS_EXTRA variables is a
-// colon-separated pair <apex>:<library>, where <apex> is the variant name of a non-updatable APEX,
-// "platform" if the library is a part of the platform in the system partition, or "system_ext" if
-// it's in the system_ext partition.
-//
-// In these variables APEXes are identified by their "variant names", i.e. the names they get
-// mounted as in /apex on device. In Soong modules that is the name set in the "apex_name"
-// properties, which default to the "name" values. For example, many APEXes have both
-// com.android.xxx and com.google.android.xxx modules in Soong, but take the same place
-// /apex/com.android.xxx at runtime. In these cases the variant name is always com.android.xxx,
-// regardless which APEX goes into the product. See also android.ApexInfo.ApexVariationName and
-// apex.apexBundleProperties.Apex_name.
-//
-// A related variable PRODUCT_APEX_BOOT_JARS contains bootclasspath libraries that are in APEXes.
-// They are not included in the boot image. The only exception here are ART jars and core-icu4j.jar
-// that have been historically part of the boot image and are now in apexes; they are in boot images
-// and core-icu4j.jar is generally treated as being part of PRODUCT_BOOT_JARS.
-//
-// One exception to the above rules are "coverage" builds (a special build flavor which requires
-// setting environment variable EMMA_INSTRUMENT_FRAMEWORK=true). In coverage builds the Java code in
-// boot image libraries is instrumented, which means that the instrumentation library (jacocoagent)
-// needs to be added to the list of bootclasspath DEX jars.
-//
-// In general, there is a requirement that the source code for a boot image library must be
-// available at build time (e.g. it cannot be a stub that has a separate implementation library).
-//
-// 2.2. Static configs
-// -------------------
-//
-// Because boot images are used to dexpreopt other Java modules, the paths to boot image files must
-// be known by the time dexpreopt build rules for the dependent modules are generated. Boot image
-// configs are constructed very early during the build, before build rule generation. The configs
-// provide predefined paths to boot image files (these paths depend only on static build
-// configuration, such as PRODUCT variables, and use hard-coded directory names).
-//
-// 2.3. Singleton
-// --------------
-//
-// Build rules for the boot images are generated with a Soong singleton. Because a singleton has no
-// dependencies on other modules, it has to find the modules for the DEX jars using VisitAllModules.
-// Soong loops through all modules and compares each module against a list of bootclasspath library
-// names. Then it generates build rules that copy DEX jars from their intermediate module-specific
-// locations to the hard-coded locations predefined in the boot image configs.
-//
-// It would be possible to use a module with proper dependencies instead, but that would require
-// changes in the way Soong generates variables for Make: a singleton can use one MakeVars() method
-// that writes variables to out/soong/make_vars-*.mk, which is included early by the main makefile,
-// but module(s) would have to use out/soong/Android-*.mk which has a group of LOCAL_* variables
-// for each module, and is included later.
-//
-// 2.4. Install rules
-// ------------------
-//
-// The primary boot image and the Framework extension are installed in different ways. The primary
-// boot image is part of the ART APEX: it is copied into the APEX intermediate files, packaged
-// together with other APEX contents, extracted and mounted on device. The Framework boot image
-// extension is installed by the rules defined in makefiles (make/core/dex_preopt_libart.mk). Soong
-// writes out a few DEXPREOPT_IMAGE_* variables for Make; these variables contain boot image names,
-// paths and so on.
