lowerAsmOperandForConstraint()

bool InlineAsmLowering::lowerAsmOperandForConstraint ( Value *  Val, StringRef  Constraint, std::vector< MachineOperand > &  Ops, MachineIRBuilder &  MIRBuilder  ) const

virtual

Lower the specified operand into the Ops vector.

Val is the IR input value to be lowered Constraint is the user supplied constraint string Ops is the vector to be filled with the lowered operands

Returns

True if the lowering succeeds, false otherwise.
