Member Data Documentation

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

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.

Definition at line 1259 of file TargetLowering.h.

Referenced by ChooseConstraint(), llvm::TargetLowering::ComputeConstraintToUse(), getMatchedOperand(), llvm::SelectionDAGLowering::GetRegistersForValue(), and isMatchingInputConstraint().

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

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

Definition at line 1263 of file TargetLowering.h.

Referenced by ChooseConstraint(), llvm::TargetLowering::ComputeConstraintToUse(), and IsOperandAMemoryOperand().

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

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.

Definition at line 1268 of file TargetLowering.h.

Referenced by llvm::TargetLowering::ComputeConstraintToUse(), and IsOperandAMemoryOperand().

MVT llvm::TargetLowering::AsmOperandInfo::ConstraintVT

ConstraintVT - The ValueType for the operand value.
