After messing with the lexer I took a deep breath and got the DMD parser hooked up and started transforming trees from DMD data structures to GCC data structures. I've done enough to get "hello world" back (for now that is my baseline - don't break things so much that "hello world" stops compiling).

Basically I got the OpenD code and updated it from DMD.36 to DMD .78 (yeah, I know, Walter released .79 today), hooked it up to the G++ front-end and started plugging in the pieces to translate back and forth. So the parsing and three semantic phases of the DMD src now run before it is turned over to GCC. It should be fairly possible to make good progress filling in these pieces until it gets hard again.

If anyone wants to try it out for themselves you can get the tarball from
the last link at
http://home.comcast.net/~benhinkle/index.html

I've only tried it on Linux and compiling "hello world".

ps. Walter, could you remove the extra closing parenthesis on line 175 of
dmd/src/dmd/module.c?

Simply amazing.  I took one look at the GCC documentation, and my brain exploded more or less instantly.

Well done!

Glad you like it, though I don't understand 3/4 of the GCC internals either. That's why the G++ code is so useful - I can just call their function "finish_expr_stmt", for instance, instead of writing one myself. Probably at some point finish_expr_stmt will have to change but for now I just want to have a compiler than runs. It's too demoralizing to work on something that doesn't actually run. The main file to fiddle around with, if you want to take a look, is d-parse.c since it has all the routines that take D things and calls the G++ equivalents.

Wooooohoooo!

Thanks a lot for your efforts! I will join you in about 3-4 weeks!

Awesome!  I'm compiling it now on my Mac OS X box.  We'll see how it turns out...

Only problem I've had thus far is that libstdc++ only seems to exist on OS X as
a static library.  Do
I need to change anything to get it to work as such?

Thanks again,

Owen

Well, no luck with that.  It failed with these errors.  Anything you can suggest to fix it?

Googling for the error gives these thread:

http://gcc.gnu.org/ml/gcc/2003-04/msg00102.html

http://gcc.gnu.org/ml/gcc-patches/2003-04/msg00175.html

It seems like the second one has a solution as a patch file. If you feel
like experimenting try using different C compilers for bootstrapping or
maybe strip out the -pendantic flag or something.
Good luck,
-Ben

Done.
