Frank Barchard	8cab2e31d7	I422ToRGB565 fix for odd widths I422ToRGB565Row_Any_AVX2 uses 2 step row conversion that calls I422ToARGBRow_AVX2 and then ARGBToRGB565. I422ToARGBRow_AVX2 expects multiple of 16 pixels. Adjust the I422ToRGB565Row_Any_AVX2 to do multiple of 16 with AVX2 and then remainder in a buffer.

With fpic and debug using stackframes, 2 registers are unavailable. So a total of 8 registers are used. Although fpic and stack frame dont apply to assembly, the compiler reserves 2 registers. The optimized version builds, so its likely freeing up the registers once it knows they are not used. These functions used to build, so compile options and/or compiler may have updated.. likely fpic was turned on. An attribute can be done to disable each, and will avoid using the 2 GPR registers, but they are still reserved and unavailable in debug builds on current compilers (gcc 4.9 and clang 3.8).

Frank Barchard	e2611a7349	document cpuid command line behavior cpu_info_ is zero for uninitialized state and all bits are off, disabling all cpu optimizations. the 1 bit indicates cpu_info_ is initialized avoiding calling the detection code again for performance. MaskCpuFlags initializes the cpu ignoring existing flags, then masks with the supplied flags and stores to cpu_info_. As a mask, -1 has no effect, enabling all cpu features that were detected, but nothing that wasnt detected. Setting to 0 will cause the next call to re-initialize the cpu, which is same as enabling all features. Setting mask to 1 will turn off all cpu features but keep the initialized bit on, so the next detection call wont reinitialize and the cpu features are all disabled. So normal behavior for command line and programatic masking is: 1 = C -1 = SIMD TBR=harryjin@google.com BUG=libyuv:600 TESTED=out64/Release/bin/run_libyuv_unittest -s libyuv_unittest --verbose --release --gtest_filter=ARGBExtractAlpha -a "--libyuv_width=1280 --libyuv_height=720 --libyuv_repeat=9999 --libyuv_flags=1 --libyuv_cpu_info=1" Review URL: https://codereview.chromium.org/2042933002 .	2016-06-08 10:38:09 -07:00

Frank Barchard	cf160cdbaa	implement I444ToABGR by swapping uv and transpose matrix U contributes to B and G. V contributes to R and G. By swapping U and V, they contribute to the opposite channels. Adjust the matrix so the U contribution is in the matrix location such that it till contribute to the new B channel and vice versa. This allows ABGR versions of YUV conversion to use the same low level code as ARGB, just using a different matrix and swapping U and V pointers. As a result the existing I444ToABGRRow functions are no longer needed and are removed. Previously this function was only Intel AVX2 optimized for Windwos. Now it is also optimized for Arm and GCC. ARMv7 Neon Was LibYUVConvertTest.I444ToABGR_Opt (75971 ms) Now LibYUVConvertTest.I444ToABGR_Opt (3672 ms) 20.6 times faster.

Frank Barchard	03da5420bc	use SIMD for I420ToARGB odd widths in a temporary buffer instead of using C for remainder. Enter a description of the change. use SIMD for I420ToARGB odd widths in a temporary buffer instead of using C for remainder. Currently the C code does not exactly match the SIMD code, so an odd width produces different pixels than an even width, causing a subtle artifact. By using SIMD consistently, there is no difference in even and odd widths. Also the SIMD performance is faster, so even with overhead of memcpy, performance improves.
