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

vpx_asm_stubs.c only references these sse2 functions. Combine the files similar to the way the ssse3/avx2 files are set up. Mark the intrinsics as static because they are only used within the macros here. It is unfortunate that the assembly functions can not be marked static as well.

2018-09-20sanitizer: fix unaligned load/storesMatthias Räncker
When built with -fsanitizer=address,undefined a number of tests, such as ByteAlignmentTest.SwitchByteAlignment or ByteAlignmentTest.SwitchByteAlignment produce runtime errors about unaligned 4-byte loads/stores. While normally not really a problem, this does technically violate the language and it is eays to fix in a standard conforming way using memcpy which does not produce inferior code.

2018-09-18Fix stack corruption with x86 and --enable-picMatthias Räncker
x86inc.asm's cglobal macro is frequently used to declare more arguments than the function actually has. Normally, this is done to aquire an alias to a register that would correspond to that positional function argument if it existed. This is safe when used in this manner. In the case fixed here, however, the alias is used to temporarily store adresses obtained through the GOT in memory. Because those extra arguments don't actually exist, those stores corrupt the callers stack frame. SSE2/VpxHBDSubpelVarianceTest.Ref is a test that may fail as a result. To simply fix the space allocated to actual arguments that have been loaded into registers already is reused. This avoids having to allocate extra space for local variables. Also removed duplicate code while at it. Signed-off-by: Matthias Räncker <theonetruecamper@gmx.de> Change-Id: I505281ecaa6be586185fe6a2d34d62bdf40c839f
