[PATCH] Fix PR 28684


:ADDPATCH middle-end (math optimizations):


Hello,

Following message http://gcc.gnu.org/ml/gcc-patches/2006-09/msg01075.html
attached are two patches that should answer PR 28684. The first patch
implements -fassociative-math flag which allow reordering of floating
points numbers. The second implements -freciprocal-math flag which allow
reciprocal operations on floats.  Both flags are drived from the
-funsafe-math-optimizations flag as described in PR 28684.

Bootstrap & regression passed on Linux Powerpc.

Comments are welcome.

Revital
