Andrew, this is not a duplicate of #323.
I know why floating point results differ. I know there are
architecture-specific options that result in a more consistent floating point
model. (As far as I know, -ffloat-store isn't one of them other than very
specific cases where intermediates are assigned to actual variables.) What I
want is a non-architecture-specific option that turns on features that give a
consistent floating point model, if they exist.
As I pointed out, such options exist in other compilers.
