What's the current state of AROS on 68K / PPC ?

68k port works, but only on the Palm (and 68k linux hosted), as no one has ported AROS to the Amiga hardware :lol:

Hit a stumbling bock on the PPC, though as it seems that the varargs function has different behaviour on different platforms (passing parameters in registers or on the stack)... the best option would be to remove it from the AROS core, but apparently that would take a huge amount of work :-(

Mmm. Since it's an AmigaOS compatible project, why weren't TagLists used for variable length argument calls? Admittedly they use more stack but the idea works well enough.

Are there a lot of varargs functions? Other than for formatted IO and wrapping Taglist calls in a more C compliant way, are they essential?

Buh...

If you have an array of tags on the stack, terminated with TAG_DONE, 0, why do you need to do any dodgy varargs stuff anyway? It's no different in many ways to a zero terminated C string :-/

[Karlos]

Since a TagList is an array of struct TagItem, I'd be amazed if it was not passed by reference on any platform. Still, when you have so many registers as PPC I can see it might occur for short taglits.

As for the driver thing, no chance - I get only a few hours a week to work on my own stuff as it is and thanks to work I generally can't be bothered even then :-(

[Karlos]

Hmm. I'm not about to attempt the reverse engineering of the OS4 bootloader if that is what you are hinting at :-P

Even if I lacked the requisite scruples, long lists of PPC asm does my nut in :lol:

[Karlos]

Ah. Oops :lol:

PPC asm isnt as evil as x86 though, IMHO, but the mnemonics are a {bleep}*

-edit-

*:lol: Ok, a "female dog" then ;-)

680x0 asm owns all. An asm you can actually enjoy using!

I used to think that too... but now I like MIPS more :-)

I don't know MIPS asm :-(
