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'. Signed-off-by: Jin Bo <jinbo@loongson.cn> Reviewed-by: yinshiyou-hf@loongson.cn Signed-off-by: Michael Niedermayer <michael@niedermayer.cc> |

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.

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).

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> |

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
