+Author: H.J. Lu

+x86: Add x86_64 to x86-64 HWCAP [BZ #22093]
+
+Before glibc 2.26, ld.so set dl_platform to "x86_64" and searched the
+"x86_64" subdirectory when loading a shared library.  ld.so in glibc
+2.26 was changed to set dl_platform to "haswell" or "xeon_phi", based
+on supported ISAs.  This led to shared library loading failure for
+shared libraries placed under the "x86_64" subdirectory.
+
+This patch adds "x86_64" to x86-64 dl_hwcap so that ld.so will always
+search the "x86_64" subdirectory when loading a shared library.
+
+NB: We can't set x86-64 dl_platform to "x86-64" since ld.so will skip
+the "haswell" and "xeon_phi" subdirectories on "haswell" and "xeon_phi"
+machines.
+
+Tested on i686 and x86-64.
+
+[BZ #22093]
+* sysdeps/x86/cpu-features.c (init_cpu_features): Initialize
+GLRO(dl_hwcap) to HWCAP_X86_64 for x86-64.

+commit 922369032c604b4dcfd535e1bcddd4687e7126a5

+
+[AArch64] Optimized memcmp.
+
+This is an optimized memcmp for AArch64.  This is a complete rewrite
+using a different algorithm.  The previous version split into cases
+where both inputs were aligned, the inputs were mutually aligned and
+unaligned using a byte loop.  The new version combines all these cases,
+while small inputs of less than 8 bytes are handled separately.
+
+This allows the main code to be sped up using unaligned loads since
+there are now at least 8 bytes to be compared.  After the first 8 bytes,
+align the first input.  This ensures each iteration does at most one
+unaligned access and mutually aligned inputs behave as aligned.
+After the main loop, process the last 8 bytes using unaligned accesses.
+
+This improves performance of (mutually) aligned cases by 25% and
+unaligned by >500% (yes >6 times faster) on large inputs.
