Struct cranelift_codegen::machinst::lower::LowerInput[−][src]

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

A representation of all of the ways in which an instruction input is available: as a producing instruction (in the same color-partition), as a constant, and/or in an existing register. See LowerCtx::get_input for more details.

Fields

reg: Reg

The value is live in a register. This option is always available. Call LowerCtx::use_input_reg() if the register is used.

inst: Option<(Inst, usize)>

An instruction produces this value; the instruction’s result index that produces this value is given.

constant: Option<u64>

The value is a known constant.
