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.

2009-07-30-PEICrash.ll When fp is not eliminated, instructions with T2_i12 modes will be changed to T2_i8 ones. Take that into consideration when determining stack size limit for reserving register scavenging slot. 2009-07-30 23:29:25 +00:00

2009-08-02-CoalescerBug.ll Fix a coaelescer bug. If a copy val# is extended to eliminate a non-trivially coalesced copy, and the copy kills its source register. Trim the source register's live range to the last use if possible. This fixes up kill marker to make the scavenger happy. 2009-08-03 08:41:59 +00:00
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

2009-08-06-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
