** Description changed: To mitigate Spectre Variant 2, gcc needs to have retpoline support (-mindirect-branch and -mfunction-return arguments on amd64 and i386). Packages with this will go into the proposed pockets but need to be published in the -security pockets for their respective releases. + + Patches for gcc-4.8 were pulled from H.J. Lu's backport branch to 4.9, + available at https://github.com/hjl-tools/gcc/tree/hjl/indirect/gcc- + 4_9-branch/master . Upstream GCC does not seem to be applying patches to + anything older than the gcc-6-branch. H.J. Lu is the author of the + upstream retpoline commits as well.
