* Added a separate class (PBQPBuilder) for PBQP Problem construction. This ↵Lang Hames2010-09-188-174/+572
| | | | | | | | | | | | | | 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

* Invert the logic of reachesChainWithoutSideEffects(). What we want to check ↵Owen Anderson2010-09-182-7/+33
| | | | | | | | | | | 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
