[PATCH] D30588: [LTO] Add module asm uses to the llvm.compiler.used before merging

[Peter Collingbourne via Phabricator via llvm-commits]

pcc added a comment.

Will your test case work without LTO? I'd expect the user to have to use `__attribute((used))` to prevent the `io_cancel_local_0_4` symbol from being DCE'd.
