Expand description

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.

Implementations

impl LibCall[src]

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

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

pub fn all_libcalls() -> &'static [LibCall][src]

Get a list of all known LibCall’s.
