So I'd like to use this with gcc-4.7 or later, specifically to use a
mips24k and mips74k targeting cross compiler. Apparently the later gcc
compilers generate much tighter mips assembly and I'd like to test
this theory out.
Since i haven't had to this manually in a long, long time, does
someone have a howto/example for how to install a cross-compiler from
ports, then make this patch use it for building?
I think (?) that generating mips74k code requires a new set of
binutils (for any added instructions) but I'm not 100% on that. Again,
this is uncharted territory.
I'll give this more of a whirl (and test the resulting built
components!) if I can get a little hand-holding here.
