The name of a runtime library routine.

Runtime library calls are generated for Cranelift IR instructions that don't have an equivalent ISA instruction or an easy macro expansion. A LibCall is used as a well-known name to refer to the runtime library routine. This way, Cranelift doesn't have to know about the naming convention in the embedding VM's runtime library.

This list is likely to grow over time.

Methods

impl LibCall[src]

pub fn for_inst(opcode: Opcode, ctrl_type: Type) -> Option<Self>[src]

Get the well-known library call name to use as a replacement for an instruction with the given opcode and controlling type variable.

Returns None if no well-known library routine name exists for that instruction.
