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

[Dan Gohman]

Changes in directory llvm/utils/TableGen:

CodeGenInstruction.h updated: 1.30 -> 1.31
CodeGenTarget.cpp updated: 1.94 -> 1.95
InstrInfoEmitter.cpp updated: 1.62 -> 1.63
---
Log message:

Revert the earlier change that removed the M_REMATERIALIZABLE machine
instruction flag, and use the flag along with a virtual member function
hook for targets to override if there are instructions that are only
trivially rematerializable with specific operands (i.e. constant pool
loads).
