* Use getSCEV instead of getUnknown to create a SCEV for aDan Gohman2009-06-291-3/+3
| | | | | | | | | | | Constant. This lets ConstantInts be handled as SCEVConstant instead of SCEVUnknown, as getUnknown no longer has special-case code for ConstantInt and friends. This usually doesn't affect the final output, since the constants end up getting folded later, but it does make intermediate expressions more obvious in many cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74459 91177308-0d34-0410-b5e6-96231b3b80d8

* Implement Thumb2 ldr.Evan Cheng2009-06-2911-156/+387
| | | | | | | After much back and forth, I decided to deviate from ARM design and split LDR into 4 instructions (r + imm12, r + imm8, r + r << imm12, constantpool). The advantage of this is 1) it follows the latest ARM technical manual, and 2) makes it easier to reduce the width of the instruction later. The down side is this creates more inconsistency between the two sub-targets. We should split ARM LDR instruction in a similar fashion later. I've added a README entry for this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74420 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove the block from the LoopInfo, rather than just the Loop.Dan Gohman2009-06-271-1/+1
| | | | | | | | LoopInfo will handle removing it from the Loop, as well as updating its own tables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74398 91177308-0d34-0410-b5e6-96231b3b80d8
* Teach LoopSimplify how to merge multiple loop exits into a single exit,Dan Gohman2009-06-272-1/+76
| | | | | | | | | | | | | | | | | when one of them can be converted to a trivial icmp and conditional branch. This addresses what is essentially a phase ordering problem. SimplifyCFG knows how to do this transformation, but it doesn't do so if the primary block has any instructions in it other than an icmp and a branch. In the given testcase, the block contains other instructions, however they are loop-invariant and can be hoisted. SimplifyCFG doesn't have LoopInfo though, so it can't hoist them. And, it's important that the blocks be merged before LoopRotation, as it doesn't support multiple-exit loops. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74396 91177308-0d34-0410-b5e6-96231b3b80d8
