--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> --- (In reply to Denis Khalikov from comment #3) > The fix was accepted to llvm https://reviews.llvm.org/D50180. I hope the > patch will be applied soon. The fix was approved but never was applied upstream and then it was closed as "Since no users anymore for this patch, closing it :)". I have no idea why they did that.
