[GD-Consoles] GCC on Dreamcast and PS2

[brian h. <bri...@py...>]

Okay, a little bit of an odd one here, but does anyone know what 
predefined symbols GCC sets when targeting DreamCast or a PS2?

For a Dreamcast I know it sets the processor target to _SH4 (and the 
various permuations), but I don't know if it sets a target for the 
operating system (presumably Linux these days?).  I haven't hunted down 
a cross-compiler just yet.

For the PS2, the GCC for EE targets the MIPS R5900(?) in, I believe, 
little-endian mode, but I can't figure out if it actually has an OS 
target -- I don't think it does.  So I'm not sure how to build a header 
file that targets MIPSLE but that can also identify whether it will be 
on a PS2 vs. some other (?) MIPS little-endia device like the 5900.  
I'm looking at the stuff on ps2dev.sourceforge.net (ee-gcc) and I've 
tried sorting through the huge amount of crap in ee-gcc -dumpspecs.

Thanks,

Hook

Becareful with all PS2 issues, as this toolchain is not the main release 
from GNU, it was modified by cygnus for sony with the R5900 stuff and is 
rarther old now.

./configure --prefix=$EE --target=mips64r5900-sf-elf

So I'm not sure how to build a header

Not sure if I follow what you are trying to achive. There is no OS 
beyond the most basic stuff in the PS2 kernel.

Brian,
You probably know this already, but the PS2 Linux Kit
(http://playstation2-linux.com) has all the build tools and doc and you
could get what you want from there I think.  Meanwhile, in case it
helps, CodeWarrior defines all of these in the prefix file presumably
indicating you need to set these in the configuration file.

/* MIPSEL */
#define MIPSEL
#define _MIPSEL
#define __MIPSEL__

/* R5900 */
#define R5900
#define _R5900
#define __R5900__
/* ee */
#define	__ee__

Cheers,
Brett
