History
Dan Gohman da65822cfc 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.

2009-08-02-CoalescerBug.ll
2009-08-04-CoalescerAssert.ll In thumb mode, r7 is used as frame register. This fixes pr4681. 2009-08-04 18:46:17 +00:00
2009-08-04-CoalescerBug.ll Another nasty coalescer bug (is there another kind): 2009-08-05 07:05:41 +00:00

2009-08-06-SpDecBug.ll It turns out most of the thumb2 instructions are not allowed to touch SP. The semantics of such instructions are unpredictable. We have just been lucky that tests have been passing. 2009-08-07 00:34:42 +00:00
2009-08-07-CoalescerBug.ll Another coalescer bug. When a dead copy is eliminated, transfer the kill to a def of the exact register rather than a super-register. 2009-08-07 07:14:14 +00:00
