Pauli Oikkonen 87a9208db8 Eliminate cvtsi64_si128 intrinsic

instruction or something..

Pauli Oikkonen f218cecb38 Remove offending hor_sad_avx2_w32 function 
Consider possibly creating a non-offending AVX2 version instead, the
way hor_sad_sse41_w32 works. Or maybe there's more essential work to
do.
 2019-03-05 22:51:41 +02:00
Pauli Oikkonen df2e6c54fd 4-unroll hor_sad_sse41_arbitrary 
This may not increase perf though because it's so rarely used
function, so keeping icache footprint may be more essential...
 2019-03-05 22:45:23 +02:00

Pauli Oikkonen 2d05ca8520 Remove width from constant-width hor_sad func params

Pauli Oikkonen 57db234d95 Move 32-wide SSE4.1 hor_sad to picture-sse41.c 
It's not used by picture-avx2.c that also includes the header, so
it should not be in the header

Pauli Oikkonen 768203a2de First version of arbitrary-width SSE4.1 hor_sad 2019-02-04 20:41:40 +02:00
Pauli Oikkonen ccf683b9b6 Start work on left and right border aware hor_sad 
Comes with 4, 8, 16 and 32 pixel wide implementations now, at some point
investigate if this can start to thrash icache
 2019-02-04 20:41:40 +02:00
Pauli Oikkonen 760bd0397d Pad the image buffer by 64 bytes from both ends 
This will be necessary for an efficient and straightforward
implementation of hor_sad for blocks over 16 pixels wide, because they
cannot use the shuffle trick because inter-lane shuffling is so hard to
do

Pauli Oikkonen 9db0a1bcda Create get_optimized_sad func for SSE4.1 2019-02-04 20:41:40 +02:00
Pauli Oikkonen 91380729b1 Add generic get_optimized_sad implementation 
NOTE: To force generic SAD implementation on devices supporting
vectorized variants, you now have to override both get_optimized_sad
and reg_sad to generic (only overriding get_optimized_sad on AVX2
hardware would just run all SAD blocks through reg_sad_avx2). Let's
see if there's a more sensible way to do it, but it's not trivial.

Pauli Oikkonen 3f7340c932 Fine-tune pack_16x16b_to_16x2b

Pauli Oikkonen 3a1f2eb752 Prefer SSE4.1 implementation of SAD over AVX2 
It seems that the 128-bit wide version consistently outperforms the
256-bit one
 2019-01-10 13:48:55 +02:00
Pauli Oikkonen 9b24d81c6a Use SSE instead of AVX for small widths 
Highly dubious if this will help performance at all
 2019-01-07 20:12:13 +02:00
Pauli Oikkonen b2176bf72a Optimize SSE4.1 version of SAD 
Make it use the same vblend trick as AVX2. Interestingly, on my test

vectors.
 2019-01-07 19:40:57 +02:00
Pauli Oikkonen 887d7700a8 Modify AVX2 SAD to mask data by byte granularity in AVX registers

Sergei Trofimovich 68a70e45a1 x86 asm: mark stack as non-executable 
Gentoo's `scanelf` QA tool detects writable/executable stack
of assembly-writtent files as:

```
$ scanelf -qRa  .
 0644 LE !WX --- ---     ./src/strategies/x86_asm/.libs/picture-x86-asm-sad.o
 0644 LE !WX --- ---     ./src/strategies/x86_asm/.libs/picture-x86-asm-satd.o
 0644 LE !WX --- ---     ./src/strategies/x86_asm/picture-x86-asm-sad.o
 0644 LE !WX --- ---     ./src/strategies/x86_asm/picture-x86-asm-satd.o
```

Normally C compiler emits non-executable stack marking (or GNU assembler
via `-Wa,--noexecstack`).

The change adds non-executable stack marking for yasm-based assmbly files.
