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 :-) Segher
