2011-06-30Refact ARM Thumb1 tMOVr instruction family.Jim Grosbach
Merge the tMOVr, tMOVgpr2tgpr, tMOVtgpr2gpr, and tMOVgpr2gpr instructions into tMOVr. There's no need to keep them separate. Giving the tMOVr instruction the proper GPR register class for its operands is sufficient to give the register allocator enough information to do the right thing directly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134204 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-30Thumb1 register to register MOV instruction is predicable.Jim Grosbach
Fix a FIXME and allow predication (in Thumb2) for the T1 register to register MOV instructions. This allows some better codegen with if-conversion (as seen in the test updates), plus it lays the groundwork for pseudo-izing the tMOVCC instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134197 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-30Reapply r134047 now that the world is ready for it.Jakob Stoklund Olesen
This patch will sometimes choose live range split points next to interference instead of always splitting next to a register point. That means spill code can now appear almost anywhere, and it was necessary to fix code that didn't expect that. The difficult places were: - Between a CALL returning a value on the x87 stack and the corresponding FpPOP_RETVAL (was FpGET_ST0). Probably also near x87 inline assembly, but that didn't actually show up in testing. - Between a CALL popping arguments off the stack and the corresponding ADJCALLSTACKUP. Both are fixed now. The only place spill code can't appear is after terminators, see SplitAnalysis::getLastSplitPoint. Original commit message: Rewrite RAGreedy::splitAroundRegion, now with cool ASCII art. This function has to deal with a lot of special cases, and the old version got it wrong sometimes. In particular, it would sometimes leave multiple uses in the stack interval in a single block. That causes bad code with multiple reloads in the same basic block. The new version handles block entry and exit in a single pass. It first eliminates all the easy cases, and then goes on to create a local interval for the blocks with difficult interference. Previously, we would only create the local interval for completely isolated blocks. It can happen that the stack interval becomes completely empty because we could allocate a register in all edge bundles, and the new local intervals deal with the interference. The empty stack interval is harmless, but we need to remove a SplitKit assertion that checks for empty intervals. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134125 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-29Remove redundant Thumb2 ADD/SUB SP instruction definitions.Jim Grosbach
Unlike Thumb1, Thumb2 does not have dedicated encodings for adjusting the stack pointer. It can just use the normal add-register-immediate encoding since it can use all registers as a source, not just R0-R7. The extra instruction definitions are just duplicates of the normal instructions with the (not well enforced) constraint that the source register was SP. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134114 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-29Always adjust the stack pointer immediately after the call.Jakob Stoklund Olesen
Some x86-32 calls pop values off the stack, and we need to readjust the stack pointer after the call. This happens when ADJCALLSTACKUP is eliminated. It could happen that spill code was inserted between the CALL and ADJCALLSTACKUP instructions, and we would compute wrong stack pointer offsets for those frame index references. Fix this by inserting the stack pointer adjustment immediately after the call instead of where the ADJCALLSTACKUP instruction was erased. I don't have a test case since we don't currently insert code in that position. We will soon, though. I am testing a regalloc patch that didn't work on Linux because of this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134113 91177308-0d34-0410-b5e6-96231b3b80d8
