2009-06-18On Darwin, ams printer should output a second label before a jump table so ↵Evan Cheng
the linker knows it's a new atom. But this is only needed if the jump table is put in a separate section from the function body. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73720 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-18- Update register allocation hint after coalescing. This is done by the ↵Evan Cheng
target since the hint is target dependent. This is important for ARM register pair hints. - Register allocator should resolve the second part of the hint (register number) before passing it to the target since it knows virtual register to physical register mapping. - More fixes to get ARM load / store double word working. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73671 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-16Rename RemoveCopiesFromValNo to TurnCopiesFromValNoToImpDefs.Evan Cheng
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73479 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-16If a val# is defined by an implicit_def and it is being removed, all of the ↵Evan Cheng
copies off the val# were removed. This causes problem later since the scavenger will see uses of registers without defs. The proper solution is to change the copies into implicit_def's instead. TurnCopyIntoImpDef turns a copy into implicit_def and remove the val# defined by it. This causes an scavenger assertion later if the def reaches other blocks. Disable the transformation if the value live interval extends beyond its def block. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73478 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-15CheckTailCallReturnConstraints is missing a check on theArnold Schwaighofer
incomming chain of the RETURN node. The incomming chain must be the outgoing chain of the CALL node. This causes the backend to identify tail calls that are not tail calls. This patch fixes this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73387 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-15Part 1.Evan Cheng
- Change register allocation hint to a pair of unsigned integers. The hint type is zero (which means prefer the register specified as second part of the pair) or entirely target dependent. - Allow targets to specify alternative register allocation orders based on allocation hint. Part 2. - Use the register allocation hint system to implement more aggressive load / store multiple formation. - Aggressively form LDRD / STRD. These are formed *before* register allocation. It has to be done this way to shorten live interval of base and offset registers. e.g. v1025 = LDR v1024, 0 v1026 = LDR v1024, 0 => v1025,v1026 = LDRD v1024, 0 If this transformation isn't done before allocation, v1024 will overlap v1025 which means it more difficult to allocate a register pair. - Even with the register allocation hint, it may not be possible to get the desired allocation. In that case, the post-allocation load / store multiple pass must fix the ldrd / strd instructions. They can either become ldm / stm instructions or back to a pair of ldr / str instructions. This is work in progress, not yet enabled. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73381 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-14Move register allocation preference (or hint) from LiveInterval to ↵Evan Cheng
MachineRegisterInfo. This allows more passes to set them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73346 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-13Add a ARM specific pre-allocation pass that re-schedule loads / stores fromEvan Cheng
consecutive addresses togther. This makes it easier for the post-allocation pass to form ldm / stm. This is step 1. We are still missing a lot of ldm / stm opportunities because of register allocation are not done in the desired order. More enhancements coming. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73291 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-13llvm.dbg.region.end() intrinsic is not required to be in _last_ basic block ↵Devang Patel
in a function. If that happens then any basic block that follows (lexically) the block with regin.end will not have scope info available. LexicalScopeStack relies on processing basic block in CFG order, but this processing order is not guaranteed. Things get complicated when the optimizer gets a chance to optimizer IR with dbg intrinsics. Apply defensive patch to preserve at least one lexical scope till the end of function. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73282 91177308-0d34-0410-b5e6-96231b3b80d8
