Struct cretonne_codegen::isa::OperandConstraint

pub struct OperandConstraint {
    pub kind: ConstraintKind,
    pub regclass: RegClass,
}

Register constraint for a single value operand or instruction result.

Fields

kind: ConstraintKind

The kind of constraint.

regclass: RegClass

The register class of the operand.

This applies to all kinds of constraints, but with slightly different meaning.

Methods

impl OperandConstraint

pub fn satisfied(&self, loc: ValueLoc) -> bool

Check if this operand constraint is satisfied by the given value location. For tied constraints, this only checks the register class, not that the counterpart operand has the same value location.

Trait Implementations

impl PartialEq for OperandConstraint

fn eq(&self, __arg_0: &OperandConstraint) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &OperandConstraint) -> bool

This method tests for !=.

impl Debug for OperandConstraint

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.
