Jakob Stoklund Olesen dffb051c21 Simplify RegScavenger::forward a bit more. ... Verify that early clobber registers and their aliases are not used. All changes to RegsAvailable are now done as a transaction so the order of operands makes no difference. The included test case is from PR4686. It has behaviour that was dependent on the order of operands. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78465 91177308-0d34-0410-b5e6-96231b3b80d8		2009-08-08 13:18:47 +00:00

2009-07-17-CrossRegClassCopy.ll	Emit cross regclass register moves for thumb2.	2009-07-16 23:26:06 +00:00

2009-07-23-CPIslandBug.ll	Fix up ARM constant island pass for Thumb2.	2009-07-23 18:27:47 +00:00
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
2009-08-01-WrongLDRBOpc.ll	Use the i12 variant of load / store opcodes if offset is zero. Now we pass all of multisource as well.	2009-08-03 02:38:06 +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

2009-08-04-SubregLoweringBug.ll	If the insert_subreg source is <undef>, insert an implicit_def instead of a copy.	2009-08-05 01:29:24 +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
