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.

2014-04-29Remove VP8 save_reg_neon functionYunqing Wang
This patch did a cleanup following the commit "Save NEON registers in VP8 NEON functions". The pushing/poping of callee-saved NEON registers was moved into individual NEON functions. Therefore, we don't need to save those registers at the beginning of codec. The related code was removed. Change-Id: I5648166514fc9beffb780aa138495597731f49ea
2014-04-28Save NEON registers in VP8 NEON functionsYunqing Wang
The recent compiler can generate optimized code that uses NEON registers for various operations besides floating-point operations. Therefore, only saving callee-saved registers d8 - d15 at the beginning of the encoder/decoder is not enough anymore. This patch added register saving code in VP8 NEON functions that use those registers. Change-Id: Ie9e44f5188cf410990c8aaaac68faceee9dffd31
