* finish pushing MachinePointerInfo through selectiondags. At this point,Chris Lattner2010-09-211-10/+0
| | | | | | | | I think I've audited all uses, so it should be dependable for address spaces, and the pointer+offset info should also be accurate when there. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114464 91177308-0d34-0410-b5e6-96231b3b80d8

* Invert the logic of reachesChainWithoutSideEffects(). What we want to check ↵Owen Anderson2010-09-181-7/+7
| | | | | | | | | | | 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

* Eliminate the first have of the optimization which eliminates BRCONDDan Gohman2010-06-241-3/+1
| | | | | | | | | | | | | | when the condition is constant. This optimization shouldn't be necessary, because codegen shouldn't be able to find dead control paths that the IR-level optimizer can't find. And it's undesirable, because it encourages bugpoint to leave "br i1 false" branches in its output. And it wasn't updating the CFG. I updated all the tests I could, but some tests are too reduced and I wasn't able to meaningfully preserve them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@106748 91177308-0d34-0410-b5e6-96231b3b80d8
