Peter Collingbourne a2ab4a5c5d LTO: Mark undefined module asm symbols as used. ... Marking them as used causes them to be considered visible outside of LTO. This prevents the symbols from being internalized or discarded, either by GlobalDCE or by summary-based dead stripping in ThinLTO. This change makes it unnecessary to add these symbols to llvm.compiler.used in the backend, as the symbols are kept alive by virtue of being external, so remove the backend code that handles that. Fixes PR32798. Differential Revision: https://reviews.llvm.org/D32544 llvm-svn: 301438		2017-04-26 17:53:39 +00:00
