... because GCC now has -mpc to limit precision for float/double operations.
Even as far as x86 is concerned, this is a "special case" of PR323, and thus
I'm closing it as fixed.

There is no way to get all the same fp arithmetic model on all targets as some
don't even support IEEE float, SPU comes to mind.
Please read: http://gcc.gnu.org/bugs.html#nonbugs
Also read the paper which is linked

I think the feature request is too vague and possibly x86 centric. But there
is ongoing discussion on making all the options that control FP optimization
and
conformance to language and IEEE standards less confusing

It seems the "x86 is stupid, see bug 323" blinkers have come down.
I'm not asking for anyone to alter any gcc code generation. I specifically
don't want the FP in software mentioned by kargl. The fact that gcc suppor

GCC supports many many many more CPU architectures than ifort. This
isn't going to happen unless you

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-stor
