10a061ba99 vp9: Add AVX-512ICL asm for 8bpc subpel mc 2025-08-28 12:45:52 +00:00
Ronald S. Bultje
6e13c30a8f vp9: don't overread by 4 pixels in ff_vp9_avg4_mmxext(). 
If the block is at the end of the allocated buffer and there is no
padding, this will over-read, which may cause crashes. Reported by
Firefox.

8286c359ad Merge commit 'e99ecda550' 
* commit 'e99ecda550':
  checkasm: add vp9 MC tests.
  vp9mc/x86: sse2 MC assembly.
  vp9mc/x86: add AVX and AVX2 MC
  vp9mc/x86: rename ff_* to ff_vp9_*
  vp9mc/x86: rename ff_avg[48]_sse to ff_avg[48]_mmxext
  vp9mc/x86: simplify a few inits.
  vp9mc/x86: add 16px functions (64bit only).

Noop (aside from a formatting comment in vp9mc.asm). We already have all
of this. We should consider making a final diff between the two projects
when the dust comes down.

9790b44a89 vp9mc/x86: sse2 MC assembly. 
Also a slight change to the ssse3 code, which prevents a theoretical
overflow in the sharp filter.

8be8444d01 vp9mc/x86: rename ff_avg[48]_sse to ff_avg[48]_mmxext 
pavgb is an sse integer instruction, so the mmxext flag is enough

89466de4ae vp9/x86: rename vp9dsp to vp9mc 
It only contains the MC SIMD, other SIMD will go into different files.

8729964b99 vp9: split x86 assembly in two files. 
(And in future, loopfilter or intra pred could be put in their own
respective files also.)
