* Fix pr3954. The register scavenger asserts for inline assembly withBob Wilson2009-04-091-2/+2
| | | | | | | | | | | | register destinations that are tied to source operands. The TargetInstrDescr::findTiedToSrcOperand method silently fails for inline assembly. The existing MachineInstr::isRegReDefinedByTwoAddr was very close to doing what is needed, so this revision makes a few changes to that method and also renames it to isRegTiedToUseOperand (for consistency with the very similar isRegTiedToDefOperand and because it handles both two-address instructions and inline assembly with tied registers). llvm-svn: 68714
* Oy! When reverting r68073, I added in experimental code. Sorry...Bill Wendling2009-03-311-62/+31
