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.
