unsigned TargetLowering::AsmOperandInfo::getMatchedOperand

(

)

const

If this is an input matching constraint, this method returns the output operand it matches.

getMatchedOperand - If this is an input matching constraint, this method returns the output operand it matches.

bool TargetLowering::AsmOperandInfo::isMatchingInputConstraint

(

)

const

Return true of this is an input operand that is a matching constraint like "4".

isMatchingInputConstraint - Return true of this is an input operand that is a matching constraint like "4".

Member Data Documentation

Value* llvm::TargetLowering::AsmOperandInfo::CallOperandVal

If this is the result output operand or a clobber, this is null, otherwise it is the incoming operand to the CallInst. This gets modified as the asm is processed.

std::string llvm::TargetLowering::AsmOperandInfo::ConstraintCode

This contains the actual string for the code, like "m". TargetLowering picks the 'best' code from ConstraintInfo::Codes that most closely matches the operand.

TargetLowering::ConstraintType llvm::TargetLowering::AsmOperandInfo::ConstraintType

Information about the constraint code, e.g. Register, RegisterClass, Memory, Other, Unknown.
