RFC: Inline expansion of memcmp vs call to standard library
...unctions like memcpy,
memmove, etc. This patch (https://reviews.llvm.org/D28163) is an initial
implementation for PowerPC to expand memcmp when the size is an 8 byte
multiple.
The approach currently added for this expansion tries to use the existing
infrastructure by overriding the virtual function EmitTargetCodeForMemcmp.
This function works on the SelectionDAG, but the expansion requires control
flow for early exit. So, instead of implementing the expansion within
EmitTargetCodeForMemcmp, a new pseudo instruction is added for memcmp and a
SelectionDAG node for this new pseudo is created in
EmitTargetCodeForMemcmp....
