Sanjay Patel fe346f9f5b [BDCE] clear poison generators after turning a value into zero (PR33695, PR34037) ... nsw, nuw, and exact carry implicit assumptions about their operands, so we need to clear those after trivializing a value. We decided there was no danger for llvm.assume or metadata, so there's just a comment about that. This fixes miscompiles as shown in: https://bugs.llvm.org/show_bug.cgi?id=33695 https://bugs.llvm.org/show_bug.cgi?id=34037 Differential Revision: https://reviews.llvm.org/D36592 llvm-svn: 310779		2017-08-12 16:41:08 +00:00
