--- Comment #4 from Mario Hros <k3x-devel at outlook dot com> --- I already reported the problem in the code using MMX without EMMS - it was FFMPEG (https://patchwork.ffmpeg.org/project/ffmpeg/patch/am9p193mb194004554ecf79f43679cfb2af...@am9p193mb1940.eurp193.prod.outlook.com/). This bug report is about the strange behavior where GCC doesn't seem to be using result of the fmod@plt at all. Or am I missing something?
