Both -ffast-math and -funsafe-math-optimizations violate IEEE math specs so
this is an invalid bug. At one point -funsafe-math-optimizations used to not
honor signed zero but recently you have:
-flag_signed_zeros with
2007-01-19 Roger Sayle <[EMAIL PROTECTED]>
* common.opt (fsigned-zeros): New command line option.
* flags.h (HONOR_SIGNED_ZEROS): Control via flag_signed_zeros instead
of flag_unsafe_math_optimizations.
* opts.c (set_fast_math_flags): The -ffast-math command line option
implies -fno-signed-zeros.
(fast_math_flags_set_p): Likewise.
But -funsafe-math-optimizations still says you can reassiocate so maybe this is
just the case where we want a flag for reassiocating.
