Hello, Yes. Those instructions are unimplemented, so you would have to implement them. There are some cases where unimplemented instructions can be ignored (e.g., hints to caches). However, if your application is using fdivr, it seems important. I wish I could give you a good pointer on how to implement an instruction. This homework from a few years ago may help http://pages.cs.wisc.edu/~david/courses/cs752/Fall2015/wiki/index.php?n=Main.Homework2 .
PS: The git describe is not very useful. Keeping up to date with the HEAD at gem5.googlesource.com is your best bet.
