From: Shiyou Yin <yinshiyou...@loongson.cn>
loongson_asm.S is LoongArch asm optimization helper.
Add functions:
ff_h264_idct_add_8_lsx
ff_h264_idct8_add_8_lsx
ff_h264_idct_dc_add_8_lsx
ff_h264_idct8_dc_add_8_lsx
ff_h264_idct_add16_8_lsx
ff_h264_idct8_add4_8_lsx
ff_h264_idct_add8_8_lsx
ff_h264_idct_add8_422_8_lsx
ff_h264_idct_add16_intra_8_lsx
ff_h264_luma_dc_dequant_idct_8_lsx
Replaced function(LSX is sufficient for these functions):
ff_h264_idct_add_lasx
ff_h264_idct4x4_addblk_dc_lasx
ff_h264_idct_add16_lasx
ff_h264_idct8_add4_lasx
ff_h264_idct_add8_lasx
ff_h264_idct_add8_422_lasx
ff_h264_idct_add16_intra_lasx
ff_h264_deq_idct_luma_dc_lasx
Renamed functions:
ff_h264_idct8_addblk_lasx ==> ff_h264_idct8_add_8_lasx
ff_h264_idct8_dc_addblk_lasx ==> ff_h264_idct8_dc_add_8_lasx
./configure --disable-lasx
ffmpeg -i 1_h264_1080p_30fps_3Mbps.mp4 -f rawvideo -y /dev/null -an
before: 155fps
after: 161fps
