It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody
is helped by having libavutil and libavcore split. In order to ease
maintenance inside and around FFmpeg and to reduce confusion where to
put common code, avcore's functionality is merged (back) to avutil.

(cherry picked from commit c2dd0e9eba)
Recent gcc versions define __ARM_PCS or __ARM_PCS_VFP to indicate the
VFP ABI in use, and ARM RVCT defines __SOFTFP__ when using this ABI.
If none of these are defined, check $cross_prefix and $cc for the
substring "hardfloat", and finally fall back to a linker test. This
gives the correct result in most configurations.
Some linkers fail if this flag is used when creating an executable file.
Since the flag is meaningful only for shared libraries, dropping it from
the main link flags is correct.
Fixed-point AC-3 encoder renamed to ac3_fixed.

This macro is disabled if --enable-small or --disable-optimizations are set.
Currently, this leads to warnings about functions being defined but not used,
for functions in header files.
By defining av_always_inline as inline or as av_unused, we avoid these
warnings.
This doesn't make a normal build with --enable-small any larger,
since the compiler probably chooses not to inline these functions even
if they're marked as inline.

On OS X, this struct is only available if _DARWIN_C_SOURCE is defined,
when we have _POSIX_C_SOURCE defined. This allows the struct to be found,
enabling proper IPv6 multicast functionality on OS X.
The define is already set within the file that uses the struct. Setting it
only for this test in configure avoids having to keep it defined for the
whole build.

without value when the target library is disabled.
If it does not explicitly return 0, when the last library is disabled
(swscale), the final "configure" exit value is 1, even if the

This test verifies the pixdesc code by comparing the output with and
without a filter which should have no effect on the image. Since the
available pixel formats depend on the byte order of the machine, a
simple reference checksum is not possible.
The test originally tried to solve this by generating a reference file
on the fly. The problem with this is that the test framework expects
the reference file in the source tree, and writing to the source tree
is not allowed.
To avoid complicating the test framework, we instead provide two
reference files and select which to use based on the byte order.
