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

[Dan Gohman]

Changes in directory llvm/lib/Target:

Target.td updated: 1.105 -> 1.106
---
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).
