[PATCH] [ARM] Handle conflicts between -mfpu and -mfloat-abi options

[Asiri Rathnayake]

Hi Renato,

I've been away and only now managed to pull this back. I've addressed your comment on the code but I don't understand what you mean by:

"but I think that this change will also change other ARM architectures (v4~v7) and would be good to add the same login on the prev8 side of things"

AFAICS, this code gets executed for all ARM architectures. Can you kindly explain what you meant by "add the same login"?

Cheers!
