Duncan Sands 33756f96d7 Reduce the number of dom queries made by GVN's conditional propagation ... logic by half: isOnlyReachableViaThisEdge was trying to be clever and handle the case of a branch to a basic block which is contained in a loop. This costs a domtree lookup and is completely useless due to GVN's position in the pass pipeline: all loops have preheaders at this point, which means it is enough for isOnlyReachableViaThisEdge to check that Dst has only one predecessor. (I checked this theoretical argument by running over the entire nightly testsuite, and indeed it is so!). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149838 91177308-0d34-0410-b5e6-96231b3b80d8		2012-02-05 18:25:50 +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
