Pauli Oikkonen 91b30c7064 Tidy up kvz_image_calc_sad 2019-02-04 20:41:40 +02:00
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.

version using SSE4.1

Pauli Oikkonen f186455619 Move encode_last_significant_xy out of strategy modules 
It's the exact same in both AVX2 and generic, and does not seem to
be worth even trying to vectorize

Pauli Oikkonen 3f7340c932 Fine-tune pack_16x16b_to_16x2b

one bit-shift operation from another instead. Thanks Intel for
3-operand instruction encoding!

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

simplifies the code. Also improves execution speed

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.

Pauli Oikkonen c5cd03497e Require BMI and ABM instruction sets for AVX2 build 
AVX2 support on a processor should always imply BMI and ABM support.
The lzcnt and tzcnt instructions have more suitable semantics in the
corner case that source word is 0, and allow us to even handle that
scenario without a branch. Apparently Visual Studio will already
include this support when building with AVX2 enabled, so only the
automake files need to be tweaked.
