Thanks for the reply Tom (and in reply to your message, I am modifying the interpreter)!
Yes, I think that's probably going to be the easiest way forward, all the loading code etc is quite fiddly and there's no need to duplicate it :-)
Aha, seems I threw something of a red herring with the 0x24, it was in fact decimal 24.
Ah, I'd wondered if that might be the case :-)
Judging from my current output (Warning, assembly): http://modseven.de/pastebin.php?id=1802 something went wrong around the NEED_HEAP_32 / UNPACK area.
Indeed, you seem to have lost a few instructions, some of the earlier ones seem to be out of order as well, though that could be deliberate :-) Looking at the assembly is interesting, looking good so far. There are some definite possibilities for optimization such as keeping the stack pointer in a register, and not using CALL to do MK_AP, NEED_HEAP, EVAL etc. Though you may well have these things in mind already :-) One thing to be careful of is RETURN_EVAL, this is because it should implement tail call optimisation, which can be fiddly. Of course your example doesn't include any assembly for it, so it might be correct already :-) Anyway, good luck, I'll be interested to hear how it goes :-) Tom
