[RFC,PATCH] 2 new mode attributes to replace mode(word) uses in libgcc

Hi,

Ok I see. Of course that introduces a new ABI-relevant mode(word) use I've
to deal with :(

Does it make sense to use the mode(libgcc_cmp_return) attribute for the
soft-fp compares as well or should we have an additional attribute here?

Is my patch without the "prepare_float_lib_cmp" change ok for mainline?

Bye,
