--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
So in C++, it is required that forward process happens so GCC (due to the
-ffinite-loops option which is only enabled for -O2 and above) will remove
infinite loops for C++.
Now your goldbolt link is using the C++ front-end while your comment says using
C front-end.
Once I change goldbolt to using C sources, the infinite loop is NOT removed as
expected (as -ffinite-loops is only enabled for C++).
