[FFmpeg-devel] 回复: Re: [PATCH 1/7] configure: loongson disable mipsfpu and mipsdsp optimizations

[周晓勇]

Hi,
1.The optimizations of mipsdsp are not supported by all loongson cpu.
2.The optimizations of mipsfpu and mipsdspr2 maybe supported by 3A2000/3A3000/3A4000 but not tested yet. 3.Loongson only support mmi (loongSIMD) optimizations now.
