RFC: Inline expansion of memcmp vs call to standard library
Currently on PowerPC, calls to memcmp are not expanded and are left as
library calls. In certain conditions, expansion can improve performance
rather than calling the library function as done for functions 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 expan...
