The empty squares in that table are stuff that hasn't been implemented in llvm-libc yet.  (llvm-libc is, in general, currently a work in progress.)  glibc also has a similar table in their documentation.

For "float" inputs, in some cases you can probably figure out the worst-case error across the whole range by brute force.  For wider inputs, you'd need some combination of random sampling, and brute-force of a few carefully chosen small intervals, yes.
