Code should not be moved to evaluate a floating-point expression when it
would not be evaluated in the abstract machine, if that expression could
raise an exception. Whether this should be

No, -ftrapping-math does not change the outcome.
I'm building x86_64 on RHEL 6.6.

--- Comment #7 from Andrew Pinski ---
Does adding -ftrapping-math allow it to work?
Also what target are you running on?

--- Comment #6 from Mike Liang ---
Oh, I see. You're saying this can be a problem for both QNaN and SNaN because
an ordered comparison instruction could be generated. Does this mean floating
point expressions should never be combined?

--- Comment #5 from joseph at codesourcery dot com ---
Maybe you're encountering one of the known bugs where on some
architectures GCC wrongly generated unordered comparison instructions for
ordered comparisons.

--- Comment #4 from Mike Liang ---
The test case passes both a signaling NaN and a quiet NaN through the
expression and FPE is only triggered by the signaling NaN.
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=69308
--- Comment #3 from joseph at codesourcery dot com ---
This has nothing to do with signaling NaNs; ordered comparisons raise
exceptions for quiet NaNs as well.
