I know that the upgrade to GCC 2.95.2 for CM3 was pretty difficult. I guess I can try the code generator from CM3 and see if it works any better. I kind of doubt its compatible with ezm3, though. If it comes down to hacking gcc or upgrading the code generator beyond what is already in CM3, I'm not going to have time for it in the forseeable future. > > ../gcc/configure --host=i486-unknown-freebsdelf --target=sparc64-sun-elf > > I assume you know the "sun" in your configure string is a NOOP.

I don't see anything in the config file that pays attention to what follows the "elf" part. John -- John Polstra John D. Polstra & Co., Inc.
