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

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

It's conceivable that we might not want to mark strcpy/stpcpy etc. noalias for the same reason llvm.memcpy isn't noalias: standard implementation tolerate exact overlap, and the benefit from forbidding that is small.  (Actually, I'm not sure any optimizations benefit at the moment.)  Maybe that's being overconservative, though.

(This doesn't apply to strcat.)
