Andreas Rheinhardt	a05f22eaf3	swscale/x86/swscale: Remove obsolete and harmful MMX(EXT) functions x64 always has MMX, MMXEXT, SSE and SSE2 and this means that some functions for MMX, MMXEXT, SSE and 3dnow are always overridden by other functions (unless one e.g. explicitly disables SSE2). So given that the only systems that benefit from these functions are truely ancient 32bit x86s they are removed. Moreover, some of the removed code was buggy/not bitexact and lead to failures involving the f32le and f32be versions of gray, gbrp and gbrap on x86-32 when SSE2 was not disabled. See e.g. https://fate.ffmpeg.org/report.cgi?time=20220609221253&slot=x86_32-debian-kfreebsd-gcc-4.4-cpuflags-mmx Notice that yuv2yuvX_mmx is not removed, because it is used by SSE3 and AVX2 as fallback in case of unaligned data and also for tail processing. I don't know why yuv2yuvX_mmxext isn't being used for this; an earlier version [1] of `554c2bc708` used it, but the version that was eventually applied does not.
