This is important because 64-bit PowerPC implementation have an expanded instruction set for 32-bit mode. I think I have my hands full with that project. If you have a Freescale implementations of the PowerPC64 Archecture I would like to hear more. You can propose additional targets for specific PowerPC32 processor targets. Also e500 etc. is not PowerPC architecture complient and requires a different ABI and a separate port in GLIBC. e500 is not covery by this proposal. Steven J.
