Pauli Oikkonen 8e60bbf6a6 Slightly tune 16x16 forward DCT 
Use an array of __m256i's to store temporary value, essentially letting
the compiler enforce alignment and use aligned loads and stores.

This reverts commit 1dd0619bd7.
 2019-09-05 18:21:55 +03:00
Pauli Oikkonen 55529decd5 Implement _mm256_insert_epi32 and extract pseudo-ops 
Visual Studio headers apparently lack these guys

Ari Lemmetti 1dd0619bd7 Revert to 6924d90052 due to broken visual studio build 2019-08-08 15:15:34 +03:00
Pauli Oikkonen 2852baa673 Separate sign3_diff_epu8 from calc_eo_cat

Pauli Oikkonen 9cc11976c0 Combine the delta accumulation from edge and band ddistortion into shared func 
This won't reduce object size, but there'll be less duplicate code
 2019-08-07 16:35:24 +03:00
Pauli Oikkonen 55d877bd66 Vectorize sao_edge_ddistortion 2019-08-07 16:35:24 +03:00
Pauli Oikkonen aef0f301d3 Fix function signatures 
Mark anything intended as read-only to be const, and fix alignment
 2019-08-07 16:35:24 +03:00
Pauli Oikkonen 997fd369b3 Redo calc_sao_edge_dir_avx2 
Do it wider, 32 pixels at once!
 2019-08-07 16:35:24 +03:00
Pauli Oikkonen db1e475e02 Use i32 instead of i8 for x/y offsets 
Doesn't matter too much, because this number isn't used in SIMD
computation, only as a memory reference offset.
 2019-08-07 16:35:24 +03:00
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
 2019-08-07 16:35:24 +03:00
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
 2019-08-07 16:35:24 +03:00
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.
