[PATCH] D104801: [MemCpyOpt] Enable memcpy optimization for NVPTX back-end.

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added a comment.

I've always hated how TLI acts as if the llvm intrinsics and libc/libm functions are interchangeable. TLI should have no bearing on the introduction of an intrinsic call which can be easily lowered without relying on a host library call. We should just always canonicalize to llvm.memcpy and let the backend expand it if the target needs to later
