-
-/* The main thing to look out for when comparing large blocks is that
-   the loads do not cross a page boundary when loading past the index
-   of the byte with the first difference or the first string-terminator.
-
-   For example, if the strings are identical and the string-terminator
-   is at index k, byte by byte comparison will not load beyond address
-   s1+k and s2+k; word by word comparison may load up to 3 bytes beyond
-   k; double word - up to 7 bytes.  If the load of these bytes crosses
-   a page boundary, it might cause a memory fault (if the page is not mapped)
-   that would not have happened in byte by byte comparison.
-
-   If an address is (double) word aligned, then a load of a (double) word
-   from that address will not cross a page boundary.
-   Therefore, the algorithm below considers word and double-word alignment
-   of strings separately.  */
-
-/* High-level description of the algorithm.
-
-   * The fast path: if both strings are double-word aligned,
-     use LDRD to load two words from each string in every loop iteration.
-   * If the strings have the same offset from a word boundary,
-     use LDRB to load and compare byte by byte until
-     the first string is aligned to a word boundary (at most 3 bytes).
-     This is optimized for quick return on short unaligned strings.
-   * If the strings have the same offset from a double-word boundary,
-     use LDRD to load two words from each string in every loop iteration, as in the fast path.
-   * If the strings do not have the same offset from a double-word boundary,
-     load a word from the second string before the loop to initialize the queue.
-     Use LDRD to load two words from every string in every loop iteration.
-     Inside the loop, load the second word from the second string only after comparing
-     the first word, using the queued value, to guarantee safety across page boundaries.
-   * If the strings do not have the same offset from a word boundary,
-     use LDR and a shift queue. Order of loads and comparisons matters,
-     similarly to the previous case.
-
-   * Use UADD8 and SEL to compare words, and use REV and CLZ to compute the return value.
-   * The only difference between ARM and Thumb modes is the use of CBZ instruction.
-   * The only difference between big and little endian is the use of REV in little endian
-     to compute the return value, instead of MOV.

-   s1+k and s2+k; word by word comparison may load up to 3 bytes beyond
-   k; double word - up to 7 bytes.  If the load of these bytes crosses
-   a page boundary, it might cause a memory fault (if the page is not mapped)
-   that would not have happened in byte by byte comparison.
-
-   If an address is (double) word aligned, then a load of a (double) word
-   from that address will not cross a page boundary.
-   Therefore, the algorithm below considers word and double-word alignment
-   of strings separately.  */
-
-/* High-level description of the algorithm.
-
-   * The fast path: if both strings are double-word aligned,
-     use LDRD to load two words from each string in every loop iteration.
-   * If the strings have the same offset from a word boundary,
-     use LDRB to load and compare byte by byte until
-     the first string is aligned to a word boundary (at most 3 bytes).
-     This is optimized for quick return on short unaligned strings.
-   * If the strings have the same offset from a double-word boundary,
-     use LDRD to load two words from each string in every loop iteration, as in the fast path.
-   * If the strings do not have the same offset from a double-word boundary,
-     load a word from the second string before the loop to initialize the queue.
-     Use LDRD to load two words from every string in every loop iteration.
-     Inside the loop, load the second word from the second string only after comparing
-     the first word, using the queued value, to guarantee safety across page boundaries.
-   * If the strings do not have the same offset from a word boundary,
-     use LDR and a shift queue. Order of loads and comparisons matters,
-     similarly to the previous case.
-
-   * Use UADD8 and SEL to compare words, and use REV and CLZ to compute the return value.
-   * The only difference between ARM and Thumb modes is the use of CBZ instruction.
-   * The only difference between big and little endian is the use of REV in little endian
-     to compute the return value, instead of MOV.
