2009-07-23Fix frame index elimination to correctly handle thumb-2 addressing modes ↵David Goodwin
that don't allow negative offsets. During frame elimination convert *i12 opcode to a *i8 when necessary due to a negative offset. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76883 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-16Emit cross regclass register moves for thumb2.Anton Korobeynikov
Minor code duplication cleanup. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76124 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-11Major changes to Thumb (not Thumb2). Many 16-bit instructions either ↵Evan Cheng
modifies CPSR when they are outside the IT blocks, or they can predicated when in Thumb2. Move the implicit def of CPSR to an optional def which defaults CPSR. This allows the 's' bit to be toggled dynamically. A side-effect of this change is asm printer is now using unified assembly. There are some minor clean ups and fixes as well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75359 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-08Checkpoint Thumb2 Instr info work. Generalized base code so that it can be ↵David Goodwin
shared between ARM and Thumb2. Not yet activated because register information must be generalized first. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75010 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-02Checkpoint refactoring of ThumbInstrInfo and ThumbRegisterInfo into ↵David Goodwin
Thumb1InstrInfo, Thumb2InstrInfo, Thumb1RegisterInfo and Thumb2RegisterInfo. Move methods from ARMInstrInfo to ARMBaseInstrInfo to prepare for sharing with Thumb2. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74731 91177308-0d34-0410-b5e6-96231b3b80d8
