Hmm, I've just been going over the ATPCS documentation again today. It
appears to me that GCC (even gcc-3.x) may not yet be doing the right thing
for ATPCS structure returns (the existing code is basically the old APCS
The ATPCS says that all single-word (or smaller) aggregates are returned
in r0. This is a much simpler (and efficient) definition than is
currently implemented in the compiler.
I'm continuing to work through the document, other issues may yet arrise.
