Dan Gohman	5022dd9cc9	Make tail merging handle blocks with repeated predecessors correctly, and ... remove RemoveDuplicateSuccessor, as it is no longer necessary, and because it breaks assumptions made in MachineBasicBlock::isOnlyReachableByFallthrough. Convert test/CodeGen/X86/omit-label.ll to FileCheck and add a testcase for PR4732. test/CodeGen/Thumb2/thumb2-ifcvt2.ll sees a diff with this commit due to it being bugpoint-reduced to the point where it doesn't matter what the condition for the branch is. Add some more interesting code to test/CodeGen/X86/2009-08-06-branchfolder-crash.ll, which is the testcase that originally motivated the RemoveDuplicateSuccessor code, to help verify that the original problem isn't being re-broken. llvm-svn: 79338	2009-08-18 15:18:18 +00:00
Dan Gohman	5e839321f2	If a MachineBasicBlock has multiple ways of reaching another block, ... allow it to have multiple CFG edges to that block. This is needed to allow MachineBasicBlock::isOnlyReachableByFallthrough to work correctly. This fixes PR4126. llvm-svn: 71018	2009-05-05 21:10:19 +00:00
