* avcodec/mips: Use MMI marcos to replace Loongson3 instructionsJiaxun Yang2021-07-28
| | | | | | | | | | | | | | | 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.

* libavcodec/mips: Fix build errors reported by clangJin Bo2021-06-03
| | | | | | | | | | 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'.

* libavcodec/mips: Fix specification of instruction nameJin Bo2021-05-28
| | | | | | | | | | | 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.

* avcodec/mips: [loongson] refine optimization in h264_chroma.Shiyou Yin2018-12-01
| | | | | | | 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>
