Martin Storsjö	a78f136f3f	configure: Use a separate config_components.h header for $ALL_COMPONENTS ... This avoids unnecessary rebuilds of most source files if only the list of enabled components has changed, but not the other properties of the build, set in config.h.

Mark Reid	716b396740	avfilter/vf_lut3d: add x86-optimized tetrahedral interpolation ... I spotted an interesting pattern that I didn't see before that leads to the implementation being faster. The bit shifting table I was using before is no longer needed, and was able to remove quite a few lines.  I also add use of FMA on the AVX2 version. f32 1920x1080 1 thread with prelut c impl 1434012700 UNITS in lut3d->interp,       1 runs,      0 skips 1434035335 UNITS in lut3d->interp,       2 runs,      0 skips 1423615347 UNITS in lut3d->interp,       4 runs,      0 skips 1426268863 UNITS in lut3d->interp,       8 runs,      0 skips sse2 905484420 UNITS in lut3d->interp,       1 runs,      0 skips 905659010 UNITS in lut3d->interp,       2 runs,      0 skips 915167140 UNITS in lut3d->interp,       4 runs,      0 skips 915834222 UNITS in lut3d->interp,       8 runs,      0 skips avx 574794860 UNITS in lut3d->interp,       1 runs,      0 skips 581035090 UNITS in lut3d->interp,       2 runs,      0 skips 584116720 UNITS in lut3d->interp,       4 runs,      0 skips 581460290 UNITS in lut3d->interp,       8 runs,      0 skips avx2 301698880 UNITS in lut3d->interp,       1 runs,      0 skips 301982880 UNITS in lut3d->interp,       2 runs,      0 skips 306962430 UNITS in lut3d->interp,       4 runs,      0 skips 305472025 UNITS in lut3d->interp,       8 runs,      0 skips gbrap16 1920x1080 1 thread with prelut c impl 1480894840 UNITS in lut3d->interp,       1 runs,      0 skips 1502922990 UNITS in lut3d->interp,       2 runs,      0 skips 1496114307 UNITS in lut3d->interp,       4 runs,      0 skips 1492554551 UNITS in lut3d->interp,       8 runs,      0 skips sse2 980777180 UNITS in lut3d->interp,       1 runs,      0 skips 986121520 UNITS in lut3d->interp,       2 runs,      0 skips 986489840 UNITS in lut3d->interp,       4 runs,      0 skips 998832248 UNITS in lut3d->interp,       8 runs,      0 skips avx 622212360 UNITS in lut3d->interp,       1 runs,      0 skips 622981160 UNITS in lut3d->interp,       2 runs,      0 skips 645396315 UNITS in lut3d->interp,       4 runs,      0 skips 641057075 UNITS in lut3d->interp,       8 runs,      0 skips avx2 321336400 UNITS in lut3d->interp,       1 runs,      0 skips 321268920 UNITS in lut3d->interp,       2 runs,      0 skips 323459895 UNITS in lut3d->interp,       4 runs,      0 skips 324949967 UNITS in lut3d->interp,       8 runs,      0 skips	2021-10-10 22:23:48 +02:00
