* Fix PR7096. When a block containing multiple defs is tail duplicated, theBob Wilson2010-05-101-1/+1
| | | | | | | SSAUpdater for the value from the first def may see uses of undefined values, because the later defs will not have been updated yet. llvm-svn: 103407
* Combine the implementations of the core part of the SSAUpdater andBob Wilson2010-05-041-437/+109
| | | | | | MachineSSAUpdater to avoid duplicating all the code. llvm-svn: 103060
* Update MachineSSAUpdater with the same changes I made for the IR-levelBob Wilson2010-04-261-122/+428
| | | | | | | SSAUpdater. I'm going to try to refactor this to share most of the code between them. llvm-svn: 102353

* move target-independent opcodes out of TargetInstrInfoChris Lattner2010-02-091-8/+8
| | | | | | | | | into TargetOpcodes.h. #include the new TargetOpcodes.h into MachineInstr. Add new inline accessors (like isPHI()) to MachineInstr, and start using them throughout the codebase. llvm-svn: 95687
