I found a temporary workaround for this via https://bugs.launchpad.net/bugs/1533009, which refers to https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63304; given that set of clues, I've confirmed that TARGET_CFLAGS='-Os -mpc-relative-literal-loads' fixes my build for the time being. This isn't necessarily a good solution for upstream, because only certain versions of GCC support it (although perhaps we could detect it in configure.ac until such time as appropriate relocation support is added?), but I'm mentioning it here in case any other distributors have the same problem. -- Colin Watson [cjwat...@ubuntu.com] _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org https://lists.gnu.org/mailman/listinfo/grub-devel
