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. 在2016年10月10日 19:20 ，Michael Niedermayer写道： On Mon, Oct 10, 2016 at 04:07:20PM +0800, 周晓勇 wrote: > From efccaec2b5b543eb98f0400fdaef88d9147d08c1 Mon Sep 17 00:00:00 2001 > From: Zhou Xiaoyong <zhouxiaoyong@loongson.cn> > Date: Mon, 10 Oct 2016 14:19:58 +0800 > Subject: [PATCH 1/7] configure: loongson disable mipsfpu and mipsdsp > optimizations the commit message is missing an explanation for "why?"
