[PATCH] D154364: [LTO] Allow library calls to be internalized in freestanding mode

[Steven Wu via Phabricator via llvm-commits]

steven_wu added a comment.

If we can maintain a map from some compiler builtin intrinsics to possible libcall functions that codegen can emit from them, it is possible that those functions can just be emitted as Undef in the LTO object symbol table. We can drop all the hacks that mark them as `used` to prevent them from dead stripped.
