Andreas Rheinhardt	6265b155bc	avcodec/hevcpred: Pass HEVCLocalContext when slice-threading The HEVC decoder has both HEVCContext and HEVCLocalContext structures. The latter is supposed to be the structure containing the per-slicethread state. Yet that is not how it is handled in practice: Each HEVCLocalContext has a unique HEVCContext allocated for it and each of these coincides except in exactly one field: The corresponding HEVCLocalContext. This makes it possible to pass the HEVCContext everywhere where logically a HEVCLocalContext should be used. This commit stops doing this for lavc/hevcpred as well as the corresponding mips code; the latter is untested. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	3 years ago
gxw	92fc0bfa54	avutil/mips: refactor msa SLDI_Bn_0 and SLDI_Bn macros. Changing details as following: 1. The previous order of parameters are irregular and difficult to understand. Adjust the order of the parameters according to the rule: (RTYPE, input registers, input mask/input index/..., output registers). Most of the existing msa macros follow the rule. 2. Remove the redundant macro SLDI_Bn_0 and use SLDI_Bn instead. Reviewed-by: Shiyou Yin <yinshiyou-hf@loongson.cn> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	6 years ago
gxw	a3e572d96f	avutil/mips: refine msa macros CLIP_*. Changing details as following: 1. Remove the local variable 'out_m' in 'CLIP_SH' and store the result in source vector. 2. Refine the implementation of macro 'CLIP_SH_0_255' and 'CLIP_SW_0_255'. Performance of VP8 decoding has speed up about 1.1%(from 7.03x to 7.11x). Performance of H264 decoding has speed up about 0.5%(from 4.35x to 4.37x). Performance of Theora decoding has speed up about 0.7%(from 5.79x to 5.83x). 3. Remove redundant macro 'CLIP_SH/Wn_0_255_MAX_SATU' and use 'CLIP_SH/Wn_0_255' instead, because there are no difference in the effect of this two macros.

Shiyou Yin	153c607525	avutil/mips: refactor msa load and store macros. Replace STnxm_UB and LDnxm_SH with new macros ST_{H/W/D}{1/2/4/8}. The old macros are difficult to use because they don't follow the same parameter passing rules. Changing details as following: 1. remove LD4x4_SH. 2. replace ST2x4_UB with ST_H4. 3. replace ST4x2_UB with ST_W2. 4. replace ST4x4_UB with ST_W4. 5. replace ST4x8_UB with ST_W8. 6. replace ST6x4_UB with ST_W2 and ST_H2. 7. replace ST8x1_UB with ST_D1. 8. replace ST8x2_UB with ST_D2. 9. replace ST8x4_UB with ST_D4. 10. replace ST8x8_UB with ST_D8. 11. replace ST12x4_UB with ST_D4 and ST_W4. Examples of new macro: ST_H4(in, idx0, idx1, idx2, idx3, pdst, stride) ST_H4 store four half-word elements in vector 'in' to pdst with stride. About the macro name: 1) 'ST' means store operation. 2) 'H/W/D' means type of vector element is 'half-word/word/double-word'. 3) Number '1/2/4/8' means how many elements will be stored. About the macro parameter: 1) 'in0, in1...' 128-bits vector. 2) 'idx0, idx1...' elements index. 3) 'pdst' destination pointer to store to 4) 'stride' stride of each store operation.
