--- Comment #25 from Markus Trippelsdorf <trippels at gcc dot gnu.org> --- Created attachment 40956 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=40956&action=edit estat warning Even gcc-5.4 warns about estat with -O3, so this is not a 7 regression. If anything, lets track it elsewhere. So please commit your reshape patch and then we can close this bug. Thanks.
