2010-09-18Fixed non-const iterator error.Lang Hames
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114273 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-18Added a separate class (PBQPBuilder) for PBQP Problem construction. This ↵Lang Hames
class can be extended to support custom constraints. For now the allocator still uses the old (internal) construction mechanism by default. This will be phased out soon assuming no issues with the builder system come up. To invoke the new construction mechanism just pass '-regalloc=pbqp -pbqp-builder' to llc. To provide custom constraints a Target just needs to extend PBQPBuilder and pass an instance of their derived builder to the RegAllocPBQP constructor. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114272 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-18Invert the logic of reachesChainWithoutSideEffects(). What we want to check ↵Owen Anderson
is that there is NO path to the destination containing side effects, not that SOME path contains no side effects. In practice, this only manifests with CombinerAA enabled, because otherwise the chain has little to no branching, so "any" is effectively equivalent to "all". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114268 91177308-0d34-0410-b5e6-96231b3b80d8

value should be in GPRs when it's going to be used as a scalar, and we use VMOVRRD to make that happen, but if the value is converted back to a vector we need to fold to a simple bit_convert.

2010-09-17Update tests to handle MC-inst instruction printing of shift operations. TheJim Grosbach
legacy asm printer uses instructions of the form, "mov r0, r0, lsl #3", while the MC-instruction printer uses the form "lsl r0, r0, #3". The latter mnemonic is correct and preferred according the ARM documentation (A8.6.98). The former are pseudo-instructions for the latter. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114221 91177308-0d34-0410-b5e6-96231b3b80d8
