Shiyou Yin	776909e42e	avcodec/mips: [loongson] reoptimize put and add pixels clamped functions. ... Simplify the usage of intermediate variable addr and remove unused variable all64 in following functions: 1. ff_put_pixels_clamped_mmi 2. ff_put_signed_pixels_clamped_mmi 3. ff_add_pixels_clamped_mmi This optimization speed up mpeg4 decode about 2% on loongson platform(tested with 3A3000).

Zhou Xiaoyong	89ec4adad6	avcodec/mips: loongson optimize mmi load and store operators ... 1.MMI_ load/store macros are defined in libavutil/mips/mmiutils.h 2.Replace some unnecessary unaligned access with aligned operator 3.The MMI_ load/store is compatible with cpu loongson2e/2f which not support instructions start with gs Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	8 years ago
ZhouXiaoyong	8392794c92	avcodec/mips/idctdsp_mmi: Version 2 of the optimizations for loongson mmi ... 1. no longer use the register names directly and optimized code format 2. to be compatible with O32, specify type of address variable with mips_reg and handle the address variable with PTR_ operator Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
