Jiaxun Yang	1042039ccd	avcodec/mips: Use MMI marcos to replace Loongson3 instructions Loongson3's extention instructions (prefixed with gs) are widely used in our MMI codebase. However, these instructions are not avilable on Loongson-2E/F while MMI code should work on these processors. Previously we introduced mmiutils marcos to provide backward compactbility but newly commited code didn't follow that. In this patch I revised the codebase and converted all these instructions into MMI marcos to get Loongson2 supproted again.

Jin Bo	fd5fd48659	libavcodec/mips: Fix build errors reported by clang Clang is more strict on the type of asm operands, float or double type variable should use constraint 'f', integer variable should use constraint 'r'.

Jin Bo	ebedd26eef	libavcodec/mips: Fix specification of instruction name 1.'xor,or,and' to 'pxor,por,pand'. In the case of operating FPR, gcc supports both of them, clang only supports the second type. 2.'dsrl,srl' to 'ssrld,ssrlw'. In the case of operating FPR, gcc supports both of them, clang only supports the second type.

Shiyou Yin	5982614af1	avcodec/mips: [loongson] refine optimization in h264_chroma. Remove invalid operation in the case x and y all equal 0, this refine made about 2% speedup for H264 decode on loongson platform. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	6 years ago
Shiyou Yin	f91237baf6	avcodec/mips: [loongson] reoptimize h264_chroma_mc8_mmi v2. Reoptimize function ff_put_h264_chroma_mc8_mmi and ff_avg_h264_chroma_mc8_mmi. Performance of h264 decoding improved about 5%(from 69fps to 73fps, tested on loongson 3A3000). Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	6 years ago
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	a3eb5a3cdd	avcodec/mips/h264chroma_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 3. use uld and mtc1 to workaround cpu 3A2000 gslwlc1 bug (gslwlc1 instruction extension bug in O32 ABI) Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
