struct OptimizationInfo<'tcx> {
    bb_idx: BasicBlock,
    bin_op_stmt_idx: usize,
    can_remove_bin_op_stmt: bool,
    to_switch_on: Place<'tcx>,

}

Fields§

§bb_idx: BasicBlock

Basic block to apply the optimization

§bin_op_stmt_idx: usize

Statement index of Eq/Ne assignment that can be removed. None if the assignment can not be removed - i.e the statement is used later on

§can_remove_bin_op_stmt: bool

Can remove Eq/Ne assignment

§to_switch_on: Place<'tcx>

Place that needs to be switched on. This place is of type integral

§branch_value_scalar: Scalar

Constant to use in switch target value

§branch_value_ty: Ty<'tcx>

Type of the constant value

§op: BinOp

Either Eq or Ne

§targets: SwitchTargets

Current targets used in the switch
