* all: Replace if (ARCH_FOO) checks by #if ARCH_FOOAndreas Rheinhardt2022-06-151-2/+3
| | | | | | | | | | | | | | | | | | This is more spec-compliant because it does not rely on dead-code elimination by the compiler. Especially MSVC has problems with this, as can be seen in https://ffmpeg.org/pipermail/ffmpeg-devel/2022-May/296373.html or https://ffmpeg.org/pipermail/ffmpeg-devel/2022-May/297022.html This commit does not eliminate every instance where we rely on dead code elimination: It only tackles branching to the initialization of arch-specific dsp code, not e.g. all uses of CONFIG_ and HAVE_ checks. But maybe it is already enough to compile FFmpeg with MSVC with whole-programm-optimizations enabled (if one does not disable too many components).

* avfilter/af_afir: Move ff_afir_init() to headerAndreas Rheinhardt2022-05-061-1/+28
| | | | | | | | This allows to inline it in af_afir.c (regardless of interposing); moreover it removes a dependency of the checkasm test on lavfi/af_afir.o. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avfilter/af_afir: Only keep DSP stuff in headerAndreas Rheinhardt2022-05-061-0/+34
Only the AudioFIRDSPContext and the functions for its initialization are needed outside of lavfi/af_afir.c. Also rename the header to af_afirdsp.h to reflect the change. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
