2015-02-03Use correct buffer size in vp8 subpixel varianceJohann
In vp8_sub_pixel_variance8x8_neon the temp2 buffer is only initialized to kHeight8 * kWidth8. However, in the case that xoffset != 0 and yoffset == 0, var_filter_block2d_bil_w8 is called with output_width kHeight8PlusOne. Thanks to cmugurel for diagnosing and yulius for the patch.

2014-11-06Remove asm offset dependenciesJohann
The obj_int_extract code is no longer worth maintaining. It creates significant issues when adapting for different build systems and no longer offers as significant of a performance benefit due to improvements in intrinsics. Source files will remain until the various third-party builds are updated. The neon fast quantizer has been moved to intrinsics. The armv6 version has been removed because so few remaining targets require it. Compilers and processors have improved significantly since the pack_tokens code was written. The assembly is no longer faster than the C code. pack_tokens were the only optimizations for the armv5te targets so the targets will be removed after the test infrastructure has been updated.

2014-10-31vp8 quantization -> intrinsicsJohann
Use intrinsics for neon quantization. Slight loss (<5%) of performance compared to the assembly. Roughly 10x faster on arm64 because that was running C code before. Change-Id: I7cf5242d8f29b7eab5bca6a1c20c89c9fc9ca66d
