Sure, I've attached the patch.
Wilco
Add a simple rawmemchr implementation. Use strlen for rawmemchr(s, '\0') as it is the
fastest way to search for '\0', and use memchr with an infinite size for other cases.
This is 3x faster for large sizes.
ChangeLog:
2016-04-22 Wilco Dijkstra <wdijkstr@arm.com>
* newlib/libc/machine/aarch64/Makefile.in: Add rawmemchr.S and
rawmemchr-stub.c.
* newlib/libc/machine/aarch64/Makefile.am: Likewise.
* newlib/libc/machine/aarch64/rawmemchr.S (rawmemchr): Add rawmemchr.
* newlib/libc/machine/aarch64/rawmemchr-stub.c (rawmemchr): Likewise.
