[libc-commits] [PATCH] D152507: Directly return 0 in memcmp/bcmp when input pointers point to same memory location

Hi @xiongji90 !
We explicitly don't handle this use case because it is in the critical path and we care more about latency in general than rarely occurring calls.
If `p1 == p2` is expected to occur it should be handled on the client side.

Thx for the patch though.
