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.
