I am trying to create a new gcc frontend, preferably using my OS X box
and Apple's supplied gcc as the foundation, but having some
difficulties.
I first tried getting the "current" gcc from savannah, but that didn't
want to compile at all with the gcc4.0 I have on my machine. The
errors didn't look like I would be able to overcome them easily.
I then tried the gcc-1765 package. That compiled with a bit of
tweaking, though the resulting compilers weren't usable. Leaving that
"minor" issue for later, I pressed ahead. However, this gcc seems to
be quite different from the baseline gcc, as far as I can tell. It
took quite a bit of work to get the FLIM sample front-end (
http://people.csa.iisc.ernet.in/sreejith/frontends/flim/ ) to compile.
Creating a custom front-end based on that, but including the
C/Objective-C base required all sorts of symbols to be defined not
mentioned anywhere in the documentation.
I finally got that to compile/link after by providing stubs for the
various required and am now in the process of providing actual code so
it actually runs. However, before I go any further with this, I would
like to ask wether I am moving in the right direction.
- Is gcc-1765 really a good base? What would be a good/better base?
-
- Where could I get that?
- Any other recommendations?
Thanks,
Marcel
