Rafael Espindola 06c6791742 When gvn decides to replace an instruction with another, we have to patch the ... replacement to make it at least as generic as the instruction being replaced. This includes: * dropping nsw/nuw flags * getting the least restrictive tbaa and fpmath metadata * merging ranges Fixes PR12979. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157958 91177308-0d34-0410-b5e6-96231b3b80d8		2012-06-04 22:44:21 +00:00

2011-06-01-NonLocalMemdepMiscompile.ll	When marking a block as being unanalyzable, use "Clobber" on the terminator instead of the first instruction in the block. This is a bit of a hack; "Clobber" isn't really the right marking in the first place. memdep doesn't really have any way of properly expressing "unanalyzable" at the moment. Using it on the terminator is much less ambiguous than using it on an arbitrary instruction, though.	2011-06-02 00:08:52 +00:00
