Mandeep Singh Grang	da99e33ae3	[llvm] Remove redundant --check-prefix=CHECK from tests ... Reviewers: MatzeB, mcrosier, rengolin Differential Revision: https://reviews.llvm.org/D25894 llvm-svn: 285003	2016-10-24 18:57:55 +00:00
Teresa Johnson	b35cc691ea	[ThinLTO] Prevent importing of "llvm.used" values ... Summary: This patch prevents importing from (and therefore exporting from) any module with a "llvm.used" local value. Local values need to be promoted and renamed when importing, and their presense on the llvm.used variable indicates that there are opaque uses that won't see the rename. One such example is a use in inline assembly. See also the discussion at: http://lists.llvm.org/pipermail/llvm-dev/2016-April/098047.html As part of this, move collectUsedGlobalVariables out of Transforms/Utils and into IR/Module so that it can be used more widely. There are several other places in LLVM that used copies of this code that can be cleaned up as a follow on NFC patch.
