Modified files:
sys/lib/libkern/arch/amd64: strchr.S strcmp.S strrchr.S
Added files:
sys/lib/libkern/arch/amd64: strlen.S
Log message:
Like libc, also for the kernel: Import new amd64 assembly versions of
strchr/index, strrchr/rindex, and strlen that provide a significantly
faster performance than our previous .c or .S implementations. Based
on NetBSD's code.
Tested with different amd64 CPUs.
