2009-10-02Forgot about ARM::tPUSH. It also has a new writeback operand.Evan Cheng

2009-08-13It's ok to spill a tGPR register as long as it's still allocated a low register.Evan Cheng
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78893 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-28tADDrSPI doesn't have a predicate operand, but tADDhirr and tADDi3 have.Evan Cheng
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77305 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-20Re-apply 75490, 75806 and 76177 with fixes and tests. Efficiency comesDavid Greene
next. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76486 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-20Use TII->findCommutedOpIndices to find the commute operands (rather than ↵Evan Cheng
guessing). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76472 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-20Fix some sub-reg coalescing bugs where the coalescer wasn't updating the ↵Evan Cheng
resulting interval's register class. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76458 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-20Restore AsmWriterEmitter.cpp back to 74742. The recent changes broke Thumb.Evan Cheng
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76398 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-11Smarter isel of ldrsb / ldrsh. Only make use of these when [r,r] address is ↵Evan Cheng
feasible. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75360 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

2009-06-24We should run these tests as well.Evan Cheng
