https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91428 --- Comment #5 from Marc Glisse --- Would it make sense to add a fixit hint that removes "constexpr"? I think that might make the warning a bit clearer for some users. On the other hand, if is_constant_evaluated gets removed by P1938, there is no

2019-10-12 Thread pinskia at gcc dot gnu.org
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=92077 --- Comment #1 from Andrew Pinski --- Looks like the "independent" function changes inlining decisions. Operator+ is not inlined when G is defined. This might be a heuristic issue of the translational unit growing too big with the inlining.
