[Bug rtl-optimization/323] optimized code gives strange floating point results

["bonzini at gnu dot org" <gcc-bugzilla@gcc.gnu.org>]

------- Comment #94 from bonzini at gnu dot org  2007-04-02 16:20 -------
I think that Uros' patch to add a -mpc switch for precision control would "fix"
this.

The real fix would be to automatically insert fldcw instructions before
float/double operations, in order to limit the precision of the operations. 
But I think that it would kill speed even more than -ffloat-store.
