[COMMIT] Jako gets real subroutines

All -- I Just committed the following changes. Enjoy. * New stack functions push_entry(), pop_entry() and swap_entry(). The first two exist for the support of the last one. These functions don't care what is in the stack entries. These exist to support the new 'swap' op (se

chr and ord, v0.2

Hey all. This is my first working version of chr(i, s|sc) and ord(s, i|ic). It's not nearly as clean as I'd like it. It's a lot more complicated and low-level then I'd like. It is tested only on my system with INTVAL being a long. I'd be very interested in better tests, or ideas for a better

[PATCH] Chr and ord, v0.2

This is a first run at a patch to support the ord and chr opcodes. It mainly, I'm afraid, serves as an example to show that we need to be able to transcode out of the native encoding; I have to special-case it several ways otherwise. Limitations - Ord only works on native strings if they have 8

Have I given the big "The Way Strings Should Work" talk?

I've given it a few places, but I don't know that I've sent it to perl6-internals. If not, or if I should do it again, let me know. I want to make sure we're all on the same page here. Dan --"it's like this"---

Calling conventions -- easier way?

Hey all. I just looked through the changes to jakoc, and I think the calling convention is mostly good... except for the return address. Originaly, I thought that perhaps it'd be good to put the return address after the args on the stack, so that once you've eaten the args, it's in the right pos

cvs commit: parrot/languages/jako jakoc (fwd)

All -- Dan asked me to remove the swap op, since what he really wants is rotate. So, I implemented an initial version of rotate. Here's the log entry: * core.ops: Replaced 'swap()' by 'rotate(i|ic)'. * stacks.c and stacks.h: Removed swap-related functions from my prior commit,

A new language targeted to the parrot assembler...

For a -very- primitive Scheme -> Parrot compiler, see http://216.254.0.2/~jgoff/Files/scheme.tar.gz This is purely proof-of-concept for a much more sophisticated implementation. The current tarball has support for only integer math operators and predicates, although there is minimal support for
