[llvm-commits] CVS: llvm/lib/CodeGen/MachineInstr.cpp

[Evan Cheng]

Changes in directory llvm/lib/CodeGen:

MachineInstr.cpp updated: 1.123 -> 1.124
---
Log message:

Instructions with variable operands (variable_ops) can have a number required
operands. e.g.
def CALL32r : I<0xFF, MRM2r, (ops GR32:$dst, variable_ops),
                "call {*}$dst", [(X86call GR32:$dst)]>;
TableGen should emit operand informations for the "required" operands.

Added a target instruction info flag M_VARIABLE_OPS to indicate the target
instruction may have more operands in addition to the minimum required
operands.
