This is true, but I'd wager that an altivec capable binutils is most
likely already the default for ppc, whereas the patched gcc may never
be available as an option for the distribution.
To get the assembler, just do your mmutstcase, look for the line where
your C file is compiled, copy this, changing -c to -S and -o ... to -o
I'm looking into the patched gcc. There may be a Debian developer who
would be willing to package it for the ppc. If this can be done,
would be far preferable to dealing with the assembly, so you might
want to hold off until I hear from him.
