This change make error handling simplier.
av_opt_freep_ranges may be called when some ranges are NULL,
for example after memory allocation fail.

We need the emulation to support the cases where the first
argument is the same as the fourth. To achieve this a fifth
argument working as a temporary may be needed.
Emulation that doesn't obey the original instruction semantics
can't be in x86inc.

aarch64: use EXTERN_ASM consistently for exported symbols
Merged-by: Michael Niedermayer <michaelni@gmx.at>
vector_fmul and vector_fmac_scalar are guaranteed that they can process in

Therefore, unroll them a bit.

arm: Add EXTERN_ASM to the .func and .type declarations for exported symbols
Merged-by: Michael Niedermayer <michaelni@gmx.at>
This makes the generated assembly more internally consistent,
avoiding declaring two labels for the same function (for cases
where EXTERN_ASM is empty) and not declaring a separate unprefixed
label in other cases.
This also makes sure the .func and .type delcarations have the same
prefix. They have previously not been used on the platforms
that have prefixed symbols on arm (iOS), but gas-preprocessor
has recently started using the .func declarations for adding
.thumb_func declarations for such functions.
