[llvm-commits] CVS: llvm/include/llvm/Target/TargetInstrInfo.h

[Brian Gaeke]

Changes in directory llvm/include/llvm/Target:

TargetInstrInfo.h updated: 1.57 -> 1.58

---
Log message:

As it happens, none of these TargetInstrInfo methods which are only
used in the SparcV9 backend really have anything to do with
TargetInstrInfo, so we're converting them into regular old global
functions and moving their declarations to SparcV9InstrSelectionSupport.h.
(They're mostly used as helper functions for SparcV9InstrSelection.)
