- Seems plausibly correct, or at least on the right track.
- It may depend on uarch - this approach avoids branches, but relies on fast multiplication and fast subnormals.
- Is that known statically?

#pragma STDC FENV_ACCESS onis known at translation time, yes. If that pragma is not specified a compiler is allowed to make transformations that assume round-to-nearest, set exception flags under different situations, or both.

These functions are no longer soft-float, and haven't been for a while. A different approach was used that has branches, but looks reasonable. If you still think these can be improved, I suggest you file a bugzilla against FSF glibc.
