I was going to poke at it.  If I understand correctly, the three
existing powerpc attributes are all about parameter passing and
function return values.  Tag_GNU_Power_ABI_FP says how floating point
parameters are passed and returned, Tag_GNU_Power_ABI_Vector does the
same for vectors, and Tag_GNU_Power_ABI_Struct_Return says how <= 8
byte structures are returned.  Am I missing anything, Joseph?
