[PATCH] D25456: [InstrProf] Add support for dead_strip+live_support functionality

[Vedant Kumar via Phabricator via llvm-commits]

vsk added a comment.

If llvm stopped appending __profd_foo to llvm.compiler.used, there might not be anything left to prevent the optimizer from discarding it. The current scheme of having the linker ignore N_NO_DEAD_STRIP if S_ATTR_LIVE_SUPPORT is in effect seems like a neat way to solve the issue. Is there a tidy alternative?
