* Use const qualifiers with TargetLowering. This eliminates severalDan Gohman2010-04-1770-692/+757
| | | | | | | | | | | | | | const_casts, and it reinforces the design of the Target classes being immutable. SelectionDAGISel::IsLegalToFold is now a static member function, because PIC16 uses it in an unconventional way. There is more room for API cleanup here. And PIC16's AsmPrinter no longer uses TargetLowering. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101635 91177308-0d34-0410-b5e6-96231b3b80d8

* reenable r101565, removing a problematic assertion.Chris Lattner2010-04-172-5/+2
| | | | | | | | | | | | CGSCC can delete nodes in regions of the callgraph that have already been visited. If new CG nodes are allocated to the same pointer, we shouldn't abort, just handle it correctly by assigning a new number. This should restore stability by removing invalidated pointers that *will* be reused from the densemap in the iterator. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101628 91177308-0d34-0410-b5e6-96231b3b80d8

* Re-commit my previous SSAUpdater changes. The previous version naively triedBob Wilson2010-04-173-188/+501
| | | | | | | | | | | | to determine where to place PHIs by iteratively comparing reaching definitions at each block. That was just plain wrong. This version now computes the dominator tree within the subset of the CFG where PHIs may need to be placed, and then places the PHIs in the iterated dominance frontier of each definition. The rest of the patch is mostly the same, with a few more performance improvements added in. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101612 91177308-0d34-0410-b5e6-96231b3b80d8
