Just simply out of curiosity, why keep the back-end for dmd closed source?  It would make life dev'ing on PowerPC linux so much nicer if I could just compile dmd myself instead of having to use an outdated version of gdc (no offense to the great job being done with gdc, it's just a bit dated at this point.

You wouldn't find the dmd backend very useful for PowerPC unless you are intent on using it as an x86 cross compiler.

As JJR said, this won't help you, since the backend doesn't do PPC code.

Walter keeps it closed since he also uses it for dmc and dmc++.  His backend contains some very powerful tools, such as the optimizer, which he has been developing for a very long time.  I don't expect him (or ask of him) to open it up.  It's great that the front-end is open, though, so we have GDC.

It would be nice, however, if a compiled version of the backend could be supplied in a statis library so that one can compile the front-end and link it with the backend.  This way, one can experiment with the front end.  I don't know how much more this would reveal of the back-end, however.

Perhaps we could port it to : http://llvm.org/

Good idea ~ that would quite possibly get D onto ARM and H8S (phones, etc), since llvm can emit plain C code too ...

Doesn't GDC work with GCC 3.4?
