--- Comment #11 from Sam James <sjames at gcc dot gnu.org> ---
Coming back to this: have you actually seen unexpected results from runtime
execution? (If so, please share what they were & what options you used to get
them).
The warning is a problem but it doesn't necessarily imply bad codegen. Some
warnings have FPs based on the IR that gets generated.
i.e. I think this is a FP warning bug instead.
