| | | | | | | | | | | | | | | | | | | | | | | | | 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
* Ignore DBG_VALUE machine instructions while constructing instruction ranges ↵Devang Patel2011-02-152-2/+6
| | | | | | | | | 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

* Move more fragments of spill weight calculation into CalcSpillWeights.hJakob Stoklund Olesen2011-02-144-16/+25
| | | | | | | | | | 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

* Enhance ComputeMaskedBits to know that aligned frameindexesChris Lattner2011-02-137-76/+106
| | | | | | | | | | | | | | | | | | | 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
