Struct cranelift_codegen::machinst::lower::NonRegInput

source · [−]

pub struct NonRegInput {
    pub inst: Option<(Inst, usize)>,
    pub constant: Option<u64>,
}

Expand description

A representation of all of the ways in which a value is available, aside from as a direct register.

An instruction, if it would be allowed to occur at the current location instead (see LowerCtx::get_input_as_source_or_const() for more details).
A constant, if the value is known to be a constant.

Fields

inst: Option<(Inst, usize)>

An instruction produces this value (as the given output), and its computation (and side-effect if applicable) could occur at the current instruction’s location instead.

If this instruction’s operation is merged into the current instruction, the backend must call LowerCtx::sink_inst().

constant: Option<u64>

The value is a known constant.
