Fix Sparc, s390 and AArch64 targets so that they can handle relocs against ifunc symbols found in note sections. Following on from PR 22929, I have found the same problem exists with other ifunc supporting targets too. Plus see this link for the bug being reported against the s390x binutils for Fedora rawhide: https://bugzilla.redhat.com/show_bug.cgi?id=1553705 So I am going to check in the patch below which applies the same change that H.J. made for the x86_64 target to the other affected targets. (Specifically: S390, AArch64 and Sparc). Plus it adds a new test to the linker testsuite to make sure that this problem stays fixed. bfd * elf64-s390.c (elf_s390_relocate_section): Move check for relocations against non-allocated sections to before the code that handles ifunc relocations. * elf32-s390.c (elf_s390_relocate_section): Likewise. * elfnn-aarch64.c (elfNN_aarch64_final_link_relocate): Treat relocs against IFUNC symbols in non-allocated sections as relocs against FUNC symbols. * elfxx-sparc.c (_bfd_sparc_elf_relocate_section): Likewise. ld * testsuite/ld-ifunc/ifuncmod5.s: New test. Checks that targets that support IFUNC symbols can handle relocations against those symbols in NOTE sections. * testsuite/ld-ifunc/ifuncmod5.d: New file: Driver for the new test. * testsuite/ld-ifunc/ifunc.exp: Run the new test. 2018-03-09 22:37:36 +08:00			`# name: Reloc against IFUNC symbol in NOTE section`
