class MCOperandInfo

Declaration

class MCOperandInfo { /* full declaration omitted */ };

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

public int16_t 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.
public uint8_t Flags: These are flags from the MCOI::OperandFlags enum.
public uint8_t OperandType: Information about the type of the operand.
public uint16_t Constraints: Operand constraints (see OperandConstraint enum).

¶unsigned int getGenericImmIndex() const

¶unsigned int getGenericTypeIndex() const

¶bool isBranchTarget() const

Set if this operand is a branch target.

¶bool isGenericImm() const

¶bool isGenericType() const

¶bool isLookupPtrRegClass() const

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

¶bool isOptionalDef() const

Set if this operand is a optional def.

¶bool isPredicate() const

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