* doc/invoke.texi (Optimize Options): Document the new behavior
of -funsafe-math-optimizations, that -fassociative-math requires
both -fno-signed-zeros and -fno-trapping-math and make it clear
- that -fno-trapping-math requires -fno-signaling-nans.
+ that -fno-trapping-math requires -fno-signaling-nans. Refactor
+ documentation of -ffast-math.
