--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> --- (In reply to Pali Rohár from comment #3) > Hello Andrew, have you checked if this is really duplicate? That is a different issue all together. The original issue is definitely a dup. The secondary issue looks more like a limitation in LTO on mingw.
