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 uint32_t Constraints: The 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).

¶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.
