Chandler Carruth a2deea1dcf When adding blocks to the list of those which no longer have any CFG ... conflicts, we should only be adding the first block of the chain to the list, lest we try to merge into the middle of that chain. Most of the places we were doing this we already happened to be looking at the first block, but there is no reason to assume that, and in some cases it was clearly wrong. I've added a couple of tests here. One already worked, but I like having an explicit test for it. The other is reduced from a test case Duncan reduced for me and used to crash. Now it is handled correctly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145119 91177308-0d34-0410-b5e6-96231b3b80d8		2011-11-24 08:46:04 +00:00
