Hey Luke,
I applied this patch, ran make realclean and rebuilt parrot.
All the parrot tests pass (except the two about numbers, and I
think they were failing before) but it doesn't like the code
that pirate's generating. I boiled the problem down to this:
#######
.sub __main__
newsub $P0, .Closure, _func
newsub $P1, .Continuation, done
.pcc_begin non_prototyped
.pcc_call $P0, $P1
done:
.local object result
.result result
.pcc_end
print result
print "\n"
end
.end
.pcc_sub _func non_prototyped
.local object res
res = new PerlString
res = "hello!"
.pcc_begin_return
.return res
.pcc_end_return
.end
########
When I run this, parrot says:
No more I register frames to pop!
I think the problem is coming from the .pcc_begin_return
line. This code works fine if I change the .Continuation to
a .Closure or .Coroutine... It also worked before the patch.
Do I have my calling conventions screwed up or is this a bug?
Sincerely,
