2022-06-15all: Replace if (ARCH_FOO) checks by #if ARCH_FOOAndreas Rheinhardt
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).

2021-09-26swscale/yuv2rgb: fix conversion to X2RGB10Manuel Stoeckl
This resolves a problem where conversions from YUV to X2RGB10LE would produce color values a factor 4 too small, because an 8-bit value was placed in a 10-bit channel. Signed-off-by: Manuel Stoeckl <code@mstoeckl.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
2021-07-22avutil/internal, swresample/audioconvert: Remove cpu.h inclusionsAndreas Rheinhardt
These inclusions are not necessary, as cpu.h is already included wherever it is needed (via direct inclusion or via the arch-specific headers). Also remove other unnecessary cpu.h inclusions from ordinary non-headers. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

Blackfin is a painful platform to work with, no test machines are available and the range of multimedia applications is dubious. Thus it only represents a maintenance burden.
