I'm guessing it's in C with the Moto extensions, rather than assembly, then? The current assembler is perfectly happy with altivec (might need to pass -m7400). GCC does not support altivec in any way, won't for the forseeable future, and will almost certainly never support the (badly designed - no flames, please, not again...) Motorola extensions. You're pretty much out of luck. Someone could theoretically package the Altivec-ized GCC they put together - but there may be licensing issues (not sure) and there are definitely major bugs. I don't recommend it at all. -- Daniel Jacobowitz Carnegie Mellon University MontaVista Software Debian GNU/Linux Developer
