Pauli Oikkonen 12de466ef5 Reimplement non-band SAO color reconstruction in AVX2
Streamline things to work on 32 pixels at once instead of 8
2019-08-07 16:35:24 +03:00
Pauli Oikkonen e8bff99329 Redo the SAO_TYPE_BAND subsection of AVX2 SAO color reconstruction
Vectorize it all, hope this helps with perf

Pauli Oikkonen 7b5dffa855 Implement calc_sao_offset_array in AVX2
To be efficient, the AVX2 color reconstruction algorithm will need
offsets in byte, not dword, arrays. This is completely specific to 8-bit
pixels and the function signature is fundamentally distinct from the
generic algorithm, so it's better to not strategize SAO offset array
calculation.

Pauli Oikkonen 08881f5e9b (TEMP) (TODO) (whatever) Avoid compiler warnings
I want the CI to not crash on its -Wall -Werror, but instead to actually
build the thing and report me about actual memory errors etc

Pauli Oikkonen c18adc5ee0 Redo sao_band_ddistortion_avx2
Avoid branching and do the entire thing on 32 pixels at once in YMMs.
Also make the sao_bands function parameter const.
