get_results opcode before call

The get_results opcode will no longer be called before the invoke instruction in the Parrot calling conventions. Instead, call and return will work the same: caller will setup a list of args and callee will fetch them, returner will set up a list of returns and returnee will fetch them.

This change has no effect on the PIR syntactic sugar for subroutine and method calls.

Change History

I have a general question about this change. Some languages require knowledge about the output arguments inside a function call. Perl5 and M come to mind immediately. If get_results is called after the call has returned, how does the function get information about the expected return arguments? Will these languages have to do some kind of manual specification of these values?
