Re: [Steven Woody] M16C development using GCC, Is It Possible?

Yes.  The target you want to use to build gcc et al is "m32c-elf".

To compile for the m16c specifically, use "m32c-elf-gcc -mcpu=m16c ..."

It means that Red Hat Inc has modified gcc (and binutils and newlib)
to support the r8c/m16c/m32c family of processors from Renesas, and
given those changes to the FSF to be integrated into their official
sources.

gdb and a simulator are still in progress.

That's a different attempt to port gcc to m16c, and has nothing to do
with what I did.

Note that I haven't gotten around to supporting C++ yet.  You can try
to build it if you want, but I had deferred it due to other more
important issues, and haven't had a chance to work on it.  It might
"just work", you never know ;-)
