GCC port to cross compile for 8-bit platforms

Z80/Z180. Is this a stupid idea or what? Has anyone done this before?

system. We did a port to an accumulator based micro and
GCC did not like it at all. LCC was much easier to get to
generate code for accumulator models.
You can still use GCC for the back end to fit with all the
cool tools.

Been Done. Look at the following page. It is a Gameboy C compiler
for a psudo Z80 like CPU. It was derived from the normal Z80
compiler (GCC). So it exist. Ask Pascal Felber were the original
Z80 GCC compiler is or change the GB compiler. Well, looking at
the web page now, it states the way GBDK (compiler) is set up
that it can target the pure Z80.

Somebody has ported GCC to the atmel avr
microcontroller architecture
look at http://medo.fov.uni-mb.si/mapp/

While we're at it, has anybody got gcc targeting Microchip PIC?
Thanks...

While I absolutely agree in the case of general C, there are
situations where I need GCC. Unfortunately only GCC support a number
of Really Nice extension, some of which are essential for decent
performance in certain applications (eg, the computed goto).
On the other hand, my experience with the GCC port for 68HC11
(http://www.irisa.fr/prive/thorn/ante.html) have definitely convinced
me that LCC is better suited for this purpose. BTW, has anyone done a
68HC11 port of LCC?

conclusion was that GCC just isn't suited to the PIC's architecture (e.g.
next to no stack) and that getting it to work is going to be more work than
writting one from scratch. A guy from HiTech said that of all the cross
compilers they sell, the PIC complier was by far the most complex, due to
the many variants with slightly different memory maps etc.
