[llvm-commits] CVS: llvm/utils/TableGen/CodeGenInstruction.h CodeGenTarget.cpp InstrInfoEmitter.cpp

[Dan Gohman]

Changes in directory llvm/utils/TableGen:

CodeGenInstruction.h updated: 1.29 -> 1.30
CodeGenTarget.cpp updated: 1.93 -> 1.94
InstrInfoEmitter.cpp updated: 1.61 -> 1.62
---
Log message:

Replace M_REMATERIALIZIBLE and the newly-added isOtherReMaterializableLoad
with a general target hook to identify rematerializable instructions. Some
instructions are only rematerializable with specific operands, such as loads
from constant pools, while others are always rematerializable. This hook
allows both to be identified as being rematerializable with the same
mechanism.
