Pauli Oikkonen 26e1b2c783 Use (u)int32_t instead of (unsigned) int in reg_sad_sse41 2019-01-10 14:37:04 +02:00
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
setup this seems to be faster than the same code using 256-bit AVX
vectors.

Pauli Oikkonen 887d7700a8 Modify AVX2 SAD to mask data by byte granularity in AVX registers 
Avoids using any SAD calculations narrower than 256 bits, and
simplifies the code. Also improves execution speed
 2019-01-07 18:53:15 +02:00
Pauli Oikkonen 7585f79a71 AVX2-ize SAD calculation 
Performance is no better than SSE though
 2019-01-07 16:26:24 +02:00
Pauli Oikkonen ab3dc58df6 Copy SAD SSE4.1 impl to AVX2 2019-01-03 18:31:57 +02:00
Ari Lemmetti b234897e8a Fix smp and amp blocks in fme and revert previous change. 
Filter 8x8 (sub)blocks even with 8x4, 4x8, 16x4, 4x16 etc.
Calculate SATD on the 8x4, ... part

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.
