2011-02-15Teach ARMLoadStoreOptimizer to remove kill flags from merged instructions as ↵Jakob Stoklund Olesen
well. This is necessary to avoid a crash in certain tangled situations where a kill flag is first correctly moved to a merged instruction, and then needs to be moved again: STR %R0, a... STR %R0<kill>, b... First becomes: STR %R0, b... STM a, %R0<kill>, ... and then: STM a, %R0, ... STM b, %R0<kill>, ... We can now remove the kill flag from the merged STM when needed. 8960050. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125591 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-15Ignore DBG_VALUE machine instructions while constructing instruction ranges ↵Devang Patel
based on location info. Machine instruction range consisting of only DBG_VALUE MIs only contributes consecutive labels in assembly output, which is harmless, and empty scope entry in DebugInfo, which confuses debugger tools. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125577 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-14Move more fragments of spill weight calculation into CalcSpillWeights.hJakob Stoklund Olesen
Simplify the spill weight calculation a bit by bypassing getApproximateInstructionCount() and using LiveInterval::getSize() directly. This changes the computed spill weights, but only by a constant factor in each function. It should not affect how spill weights compare against each other, and so it shouldn't affect code generation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125530 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-14Fix encoding and add parsing support for the arm/thumb CPS instruction:Bruno Cardoso Lopes
- Add custom operand matching for imod and iflags. - Rename SplitMnemonicAndCC to SplitMnemonic since it splits more than CC from mnemonic. - While adding ".w" as an operand, don't change "Head" to avoid passing the wrong mnemonic to ParseOperand. - Add asm parser tests. - Add disassembler tests just to make sure it can catch all cps versions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125489 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-14add a new ArrayRef class. This is intended to replace the idiom weChris Lattner
use in many places where we pass a pointer and size to abstract APIs that can take C arrays, std::vector, SmallVector, etc. It is to arrays what StringRef is to strings. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125486 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-13Enhance ComputeMaskedBits to know that aligned frameindexesChris Lattner
have their low bits set to zero. This allows us to optimize out explicit stack alignment code like in stack-align.ll:test4 when it is redundant. Doing this causes the code generator to start turning FI+cst into FI|cst all over the place, which is general goodness (that is the canonical form) except that various pieces of the code generator don't handle OR aggressively. Fix this by introducing a new SelectionDAG::isBaseWithConstantOffset predicate, and using it in places that are looking for ADD(X,CST). The ARM backend in particular was missing a lot of addressing mode folding opportunities around OR. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125470 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-13Teach instsimplify that X+Y>=X+Z is the same as Y>=Z if neither side overflows,Duncan Sands
plus some variations of this. According to my auto-simplifier this occurs a lot but usually in combination with max/min idioms. Because max/min aren't handled yet this unfortunately doesn't have much effect in the testsuite. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125462 91177308-0d34-0410-b5e6-96231b3b80d8

It caused a crash in MultiSource/Benchmarks/Bullet. Opt hit an assertion with "opt -std-compile-opts" because Constant::getAllOnesValue doesn't know how to handle floats.
