Chandler Carruth f1a60c734c Fix updateTerminator to be resiliant to degenerate terminators where ... both fallthrough and a conditional branch target the same successor. Gracefully delete the conditional branch and introduce any unconditional branch needed to reach the actual successor. This fixes memory corruption in 2009-06-15-RegScavengerAssert.ll and possibly other tests. Also, while I'm here fix a latent bug I spotted by inspection. I never applied the same fundamental fix to this fallthrough successor finding logic that I did to the logic used when there are no conditional branches. As a consequence it would have selected landing pads had they be aligned in just the right way here. I don't have a test case as I spotted this by inspection, and the previous time I found this required have of TableGen's source code to produce it. =/ I hate backend bugs. ;] Thanks to Jim Grosbach for helping me reason through this and reviewing the fix. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154867 91177308-0d34-0410-b5e6-96231b3b80d8		2012-04-16 22:03:00 +00:00
