Yes, PGI Fortran.

I wonder about that too. Time will tell!
- renox 8y agoI think that rust doesn't have (doesn't want to have) -ffast-math.
- steveklabnik 8y agoWe tend to shy away from flags like this that change behavior globally. I wonder if it could be done similar to Wrapping, where you opt into the semantics on a specific basis. I know there’s been some discussion about fast-math but I don’t remember the details.
