[PATCH] D88335: [BuildLibCalls] Add noalias for strcat and stpcpy

[Johannes Doerfert via Phabricator via llvm-commits]

jdoerfert added a comment.

FWIW, `noalias` on these arguments is, by itself, not doing anything. It does something if you know how much memory is accessed by the function through such an argument *for sure* and what other memory is accessed for sure. Such memory regions are not overlapping. (This is way too vague actually but I guess it doesn't matter for the gist.)
