Struct InstructionAllocationFacts

pub struct InstructionAllocationFacts<V, R> {
    pub uses: Vec<V>,
    pub defs: Vec<V>,
    pub constraints: InstructionConstraints<V, R>,
    pub is_copy: bool,
}

Expand description

Register-allocation facts for one target-owned machine instruction.

This deliberately contains no opcode. Backends lower their own MIR into these facts so allocation algorithms do not need a common machine IR or a target instruction enum.

Fields§

§uses: Vec<V>§defs: Vec<V>§constraints: InstructionConstraints<V, R>§is_copy: bool

Hint used by allocators which perform copy coalescing.
