2019-11-23Disable -ftrivial-auto-var-init= for hot codeVitaly Buka
This helps to improve some benchmarks by 10%, e.g. decode_time PCFullStackTest.VP9SVC_3SL_Low Bug: 1020220, 977230 Change-Id: Ic992f1eec369f46a08e19eb33bc3a7c15c1e7c87
2019-01-15Remove unnecessary calculation in 4-tap interpolation filterchiyotsai
Reduces the number of rows calculated for 2D 4-tap interpolation filter from h+7 rows to h+3 rows. Also fixes a bug in the avx2 function for 4-tap filters where the last row is computed incorrectly. Performance: | Baseline | Result | Pct Gain | bitdepth lo| 4.00 fps | 4.02 fps | 0.5% | bitdepth 10| 1.90 fps | 1.91 fps | 0.5% | The performance is evaluated on speed 1 on jets.y4m br 500 over 100 frames. No BDBR loss is observed. Change-Id: I90b0d4d697319b7bba599f03c5dc01abd85d13b1

Horizontal filter on 64x64 block: 1.59 times as fast as baseline. Vertical filter on 64x64 block: 2.5 times as fast as baseline. 2D filter on 64x64 block: 1.96 times as fast as baseline. Change-Id: I12e46679f3108616d5b3475319dd38b514c6cb3c
2018-09-15cosmetics: normalize include guardsJames Zern
use the recommended format [1] of: <PROJECT>_<PATH>_<FILE>_H_ [1] https://google.github.io/styleguide/cppguide.html#The__define_Guard "All header files should have #define guards to prevent multiple inclusion. The format of the symbol name should be <PROJECT>_<PATH>_<FILE>_H_." Change-Id: I2e8ab0b32fb23c30fa43cff5fec12d043c0d2037
2017-09-05Remove get_filter_base() and get_filter_offset() in convolveLinfeng Zhang
so that the convolve functions are independent of table alignment. Change-Id: Ieab132a30d72c6e75bbe9473544fbe2cf51541ee

2017-04-19Clean CONVERT_TO_BYTEPTR/SHORTPTR in convolveLinfeng Zhang
Replace by CAST_TO_BYTEPTR/SHORTPTR. The rule is: if a short ptr is casted to a byte ptr, any offset operation on the byte ptr must be doubled. We do this by casting to short ptr first, adding offset, then casting back to byte ptr. BUG=webm:1388 Change-Id: I9e18a73ba45ddae58fc9dae470c0ff34951fe248
2016-09-27Add compiler warning flag -Wextra and fix related warnings.Urvang Joshi
Note: some of these warnings are enabled by a combination of -Wunused (added earlier) and -Wextra. Cherry-picked from AOM 4790a69faaec8f03d65f64ff070f6ab4307dbb16 Expands use of (void)x; on unused variables. AOM only supports one codec in codec_factory.h Does not include changes to HandleDecodeResult. AOM removed invalid_file_test.cc which does use the video parameter. Does not enable -Wextra yet. There are more issues to fix. BUG=webm:1069 Change-Id: I322a1366bd4fd6c0dec9e758c2d5e88e003b1cbf

2015-08-10VPX: remove step == 16 and filter[3] != 128 checksScott LaVarnway
from FUN_CONV_1D and FUN_CONV_2D macros. The functions will not be called with these inputs. Change-Id: I67ec75e4edafc0acee70190521a80ea85dfa521b
2015-08-05VPX: remove scaled calls from FUN_CONV_1DScott LaVarnway
and FUN_CONV_2D macros. The predict lut now handles this case. The encoder now calls vpx_scaled_2d() instead of vpx_convolve8() for scaling. Change-Id: Ia1c8af8a31e4cb4887a587143108cb45835f7df7

2015-07-31Code refactor on InterpKernelZoe Liu
It in essence refactors the code for both the interpolation filtering and the convolution. This change includes the moving of all the files as well as the changing of the code from vp9_ prefix to vpx_ prefix accordingly, for underneath architectures: (1) x86; (2) arm/neon; and (3) mips/msa. The work on mips/drsp2 will be done in a separate change list. Change-Id: Ic3ce7fb7f81210db7628b373c73553db68793c46
