[llvm-commits] CVS: llvm/lib/Target/Target.td TargetSelectionDAG.td

[Evan Cheng]

Changes in directory llvm/lib/Target:

Target.td updated: 1.65 -> 1.66
TargetSelectionDAG.td updated: 1.35 -> 1.36
---
Log message:

* Removed the use of FLAG. Now use hasFlagIn and hasFlagOut instead.
* Added a pseudo instruction (for each target) that represent "return void".
  This is a workaround for lack of optional flag operand (return void is not
  lowered so it does not have a flag operand.)
