Ok, I tried to translate it to :
define mad_f_mul(x, y) \
({ mad_fixed64hi_t __hi; \
mad_fixed64lo_t __lo; \
mad_fixed_t __result; \
smull (__lo), (__hi), (__result), (x); \
movs (__lo), (__lo), lsr (MAD_F_SCALEBITS); \
adc (__result), (__lo), (__hi), lsl (32 - MAD_F_SCALEBITS); } \
__result; \
})
But doesn't seems to works.
Any idea ?
Thanks
