Go is a general-purpose language designed with systems programming
in mind. It is strongly typed and garbage-collected and has explicit
support for concurrent programming.  Programs are constructed from

}

// AbiForBodylessFuncStackMap returns the ABI for a bodyless function's stack map.
// This is not necessarily the ABI used to call it.
// Currently (1.17 dev) such a stack map is always ABI0;
// any ABI wrapper that is present is nosplit, hence a precise
// stack map is not needed there (the parameters survive only long
// enough to call the wrapped assembly function).
