This is the FPU instruction sets for ppcrossarm -i (version 2.1.4)

===============================
Supported FPU instruction sets:
SOFT
LIBGCC
FPA
FPA10
FPA11
VFP
===============================

Which are implemented?
which meas LIBGCC? all floatpoint operation are executed in libgcc?

thanks,

Jose Pascual

Any comment?
Anyone know something about it?
Is only SOFT FPU instruction sets working?

nope, fpa must be working, since some people are using it. i don't know the intricacies of the different fpa implementations, though.

libgcc can do the floating point calculations for you, but this has never worked for me. presumably you need to link to a c library and pass the float operations on to it - can anyone comment if this is worth it or will ever be implemented?
