Member Function Documentation
| unsigned TargetLowering::AsmOperandInfo::getMatchedOperand | ( | ) | const |
getMatchedOperand - If this is an input matching constraint, this method returns the output operand it matches.
Definition at line 2048 of file TargetLowering.cpp.
References llvm::LibFunc::atoi.
| bool TargetLowering::AsmOperandInfo::isMatchingInputConstraint | ( | ) | const |
isMatchingInputConstraint - Return true of this is an input operand that is a matching constraint like "4".
Definition at line 2041 of file TargetLowering.cpp.

Member Data Documentation
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.

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.

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