Status update: * Get the gcc trunk patch into F27 gcc. * Patch committed to trunk [Done -- IBM] * Rebuild gcc and libgcc [In progress -- Red Hat] * Blocked on several header issues and changes which make gcc FTBS. Working on fixing the issues. * Fedora backport [Not started] * Rebuild gcc and libgcc [Not started] * Rebuild glibc * Patch committed to trunk [In progress -- IBM] * Second round review complete, and final patch in progress. * Sync to Fedora [Waiting -- Red Hat] * Rebuild [Waiting -- Red Hat] If we're lucky we can get everything ready for the 12th, but we might need another day or two given how long it takes to build gcc on all the arches. -- Cheers, Carlos. _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx
