We backported fixes for GCC PR63304 (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63304) in our 2015.12 snapshot.
By default, GCC now uses adrp / ldr or adrp / add instructions to address the literal pools under the use of a command line option, and this mode is on by default. OTOH, CONFIG_ARM64_ERRATUM_843419 removes support for the related relocations from the kernel, hence the error you are seeing. Modifying arch/arm64/Makefile in the kernel sources to have: ifeq ($(CONFIG_ARM64_ERRATUM_843419), y) KBUILD_CFLAGS_MODULE += -mcmodel=large -mpc-relative-literal-loads endif makes the problem disappear. However, the -mpc-relative-literal-loads option is not recognized by GCC if it doesn't include the patch for GCC PR 63304, so it may not be easy to patch the Makefile. ** Bug watch added: GCC Bugzilla #63304 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63304 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1533009 Title: arm64: "unsupported RELA relocation" To manage notifications about this bug go to: https://bugs.launchpad.net/gcc-linaro/+bug/1533009/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
