Hi,

Here’s an AArch64 NEON-optimised version of memchr. It has been tested on a
Cortex-A53 and Cortex-A57 and is on these cores vastly faster than all other
C
implementations I’ve found when searching more than a few bytes.

	* libc/machine/aarch64/memchr.S: New file.
	* libc/machine/aarch64/memchr-stub.c: New file.
	* libc/machine/aarch64/Makefile.am: Add the new files.
	* libc/machine/aarch64/Makefile.in: Regenerated.

Regards,
Kévin
