Shiyou Yin 62e6b634a8 avcodec/mips: [loongson] refine process of setting block as 0 in h264dsp_mmi. In function ff_h264_add_pixels4_8_mmi, there is no need to reset '%[ftmp0]' to 0, because it's value has never changed since the start of the asm block. This patch remove the redundant 'xor' and set src to zero once it was loaded. In function ff_h264_idct_add_8_mmi, 'block' is seted to zero twice. This patch removed the first setting zero operation and move the second one after the load operation of block. In function ff_h264_idct8_add_8_mmi, 'block' is seted to zero twice too. This patch just removed the second setting zero operation. This patch mainly simplifies the implementation of functions above, the effect on the performance of whole h264 decoding process is not obvious. According to the perf data, proportion of ff_h264_idct_add_8_mmi decreased from 0.29% to 0.26% and ff_h264_idct8_add_8_mmi decreased from 0.62% to 0.59% when decoding H264 format on loongson 3A3000(For reference only , not very stable.).
