* avcodec/x86/h264dsp_init: Remove obsolete MMX(EXT) functionsAndreas Rheinhardt2022-06-22
| | | | | | | | | | | x64 always has MMX, MMXEXT, SSE and SSE2 and this means that some functions for MMX, MMXEXT and 3dnow are always overridden by other functions (unless one e.g. explicitly disables SSE2) for x64. So given that the only systems that benefit from these functions are truely ancient 32bit x86s they are removed. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/vlc: Use structure instead of VLC_TYPE array as VLC elementAndreas Rheinhardt2022-06-17
| | | | | | | | | | | | | | | | | | In C, qualifiers for arrays are broken: const VLC_TYPE (*foo)[2] is a pointer to an array of two const VLC_TYPE elements and unfortunately this is not compatible with a pointer to a const array of two VLC_TYPE, because the latter does not exist as array types are never qualified (the qualifier applies to the base type instead). This is the reason why get_vlc2() doesn't accept a const VLC table despite not modifying the table at all, as there is no automatic conversion from VLC_TYPE (*)[2] to const VLC_TYPE (*)[2]. Fix this by using a structure VLCElem for the VLC table. This also has the advantage of making it clear which element is which. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* all: Replace if (ARCH_FOO) checks by #if ARCH_FOOAndreas Rheinhardt2022-06-15
| | | | | | | | | | | | | | | | | | 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).

* avcodec/libx264: Set min build version to 158 for msvcMatt Oliver2022-06-11
| | | | | | | | | | | | | | | | | | | | | | | Was "[PATCH] libx264: Do not explicitly set X264_API_IMPORTS" Setting X264_API_IMPORTS only affects msvc builds and it breaks linking to static builds (although is required for shared builds). This flag is set by x264 in its pkgconfig as required since build 158 (a615f027ed172e2dd5380e736d487aa858a0c4ff) from July 2019. So this patch updates configure to require a newer x264 build that correctly sets the imports flag. The min version requirement of 158 is applied for msvc builds only. This is also removing the check for 'libx264 without pkg-config' which was left for compatibility reasons about 7 years ago when the pkg-config check was introduced by commit e06263ef1e0e172b2c76070b3dc739411af08e82.
