Re: [gccsdk] How to get hardware vfp with GCC?

Alas no. It gives:

error: sys.o uses FPA instructions, whereas so.riscos does not
error: sys.o uses hardware FP, whereas so.riscos uses software FP

Would gas be a better bet than asasm? Is there no way of making the
FPA flags of sys.o match those of so.riscos? After all, linking
stuff that is totally free of FP instructions must be quite
a common situation. It feels as if one is wrestling with some
bureaucracy out of Kafka.

Are there any docs on where Elf files keep their FPA flags?
Say it not in Gath, but stooping to the depths of bit-walloping
might be quicker - a bit like bribing an official ;) ?
