--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
            __asm__("fmul add %0, %2, %0\nfmul add %1, %3, %1" :"=f"
(a[j]),"=f" (b[j]) : "f" (b[j]), "f" (a[j]));


is invalid inline-asm for x86:

From

Output operands must specifically indicate which register an output appears in
after an asm. ‘=f’ is not allowed: the operand constraints must select a class
with a single register.
