D.gnu - Porting GDC?

What's involved in getting gdc on a new platform?

Is there a "C" backend for GCC - such that we could have a GDC which 
compiles D into C?

Thanks,
Steve

Do see http://www.dsource.org/projects/tdc/wiki/WhatsSupported first.

Sorry for the late response, I don't have much time to chill on the 
newsgroup these days.

I'd say first get GCC running and producing valid executables on your 
PS3.  Then once you've done that and you are comfortable with the 
config/build process of GCC, then build GCC again with the GDC module 
installed.  It will probably throw errors and complain a lot.  Then the 
fixing/tweaking/pain happens.  Hopefully the PS3 has an OS that is 
similar to Windows, Linux, or MacOS.  Hopefully the PS3 has an OS ;) 
When your compiler compiles and starts working on the library (probably 
gphobos in this case), make sure it is passing version statements for 
the platform most similar to what you are working with (ex: Windows if 
the target OS is similar to Windows).  You will probably need to alter 
the make and configure files in the D add-on.  I can't help you much 
further than that because the porting I did with arm-wince-pe and the 
PS3 porting are probably quite different in the details.

A couple points I'd like to mention:
- If you can run GCC on the PS3, it makes things nicer.  I had to build 
a cross-compiler (as opposed to a normal compiler) for arm-wince-pe, 
which was time consuming.
- If GCC already targets the PS3, or some variant(s) does, and the build 
process is simple, life is easier.  I had some reference work to help me 
with arm-wince-pe, but no shrink wrapped build process; I had to figure 
that out, which was time consuming.

Good luck with your PS3 porting endeavor!
I would really like to see this happen.  Maybe I will write a game for 
PS3 in D someday :)

Thanks for the tips Chad.

Now I just need an extra few hours in the day, or to magically find an 
intern who understands how to work with gcc.  Seriously though, I do 
want to write my next game on PS3 in D and once we wrap up what we're 
doing now, I plan on taking a strong look at this.

BTW - gcc does already work on PS3.. PS3 Linux (which anyone can install 
on their own PS3) includes it.  They have compilers for both SPE and 
PPE.  That will be my starting point.

I tried building GDC on my PS3.  I got to a certain point and gave
up.

I am running YDL on my PS3.  I downloaded the SDK 2.1 source RPMs
from the Barcelona site (http://www.bsc.es/plantillaH.php?
cat_id=304). I installed GDC 0.23 on top of the ppu-gcc code and
tried to build natively on the PS3.

First is that the cell version modifies floating point macros that
break code in in d-gcc-real.cc.  I don't know exacly what I am
doing.  To get past the errors, I changed lines like:

 REAL_ARITHMETIC(x.rv(), MINUS_EXPR, rv(), r.rv());

to
 REAL_ARITHMETIC(x.rv(), MINUS_EXPR, rv(), r.rv(), max_float_mode
());

Note, there are more macros that changed than just this one, but I
modified all the same way to give them the required machine_mode
parameter they wanted.

The compiler built after that, but then phobos failed compiling.  I
don't remember the exact error, but the error message mentioned
some floating point function like sqrt.

It seems to me that there will need to be some work to get the
floating point capabilities provided by the cell processors to work
correctly with GDC.  My real interest is getting it to run on the
spu-gcc version of the compiler which I think will be harder
still.  I did enough to realize I am a little over my head and the
build doesn't work "straight out of the box". I'd be willing to try
some experiments if people have suggestions.
