Struct cranelift_codegen::ir::entities::Immediate

source · [−]

pub struct Immediate(_);

Expand description

An opaque reference to an immediate.

Some immediates (e.g. SIMD shuffle masks) are too large to store in the InstructionData struct and therefore must be tracked separately in DataFlowGraph::immediates. Immediate provides a way to reference values stored there.

While the order is stable, it is arbitrary.
