Detailed Description

MCOperandInfo - This holds information about one operand of a machine instruction, indicating the register class for register operands, etc.

Member Function Documentation

bool llvm::MCOperandInfo::isLookupPtrRegClass ( ) const

inline

Currently no other information.

isLookupPtrRegClass - Set if this operand is a pointer value and it requires a callback to look up its register class.

Definition at line 79 of file MCInstrDesc.h.

References Flags, and llvm::MCOI::LookupPtrRegClass.

Referenced by llvm::TargetInstrInfo::getRegClass().

bool llvm::MCOperandInfo::isOptionalDef ( ) const

inline

isOptionalDef - Set if this operand is a optional def.

Definition at line 87 of file MCInstrDesc.h.

References Flags, and llvm::MCOI::OptionalDef.

Referenced by llvm::ARMTargetLowering::AdjustInstrPostInstrSelection(), llvm::TargetSchedModel::computeOperandLatency(), and llvm::MachineInstr::print().

bool llvm::MCOperandInfo::isPredicate ( ) const

inline

isPredicate - Set if this is one of the operands that made up of the predicate operand that controls an isPredicable() instruction.

Member Data Documentation

uint32_t llvm::MCOperandInfo::Constraints

Lower 16 bits are used to specify which constraints are set. The higher 16 bits are used to specify the value of constraints (4 bits each).

Definition at line 74 of file MCInstrDesc.h.

Referenced by llvm::MCInstrDesc::getOperandConstraint().

uint8_t llvm::MCOperandInfo::Flags

Flags - These are flags from the MCOI::OperandFlags enum.

Definition at line 67 of file MCInstrDesc.h.

Referenced by isLookupPtrRegClass(), isOptionalDef(), and isPredicate().

uint8_t llvm::MCOperandInfo::OperandType

OperandType - Information about the type of the operand.

Definition at line 70 of file MCInstrDesc.h.

int16_t llvm::MCOperandInfo::RegClass

RegClass - This specifies the register class enumeration of the operand if the operand is a register. If isLookupPtrRegClass is set, then this is an index that is passed to TargetRegisterInfo::getPointerRegClass(x) to get a dynamic register class.
