Re: [PATCH] add strncmp to PowerPC

Do we have any indication that it performs better than the C one ?
I would expect it to, given that the assembler one has two branches in
the per-byte loop compared to 3 in the C version.
But really, does it matter for strncmp() in the kernel?
Anyway, this asm code has bugs, as do both the current C version in the
kernel, and the code I posted. We need to do better :-)
