--- Comment #5 from Jiong Wang <jiwang at gcc dot gnu.org> ---
Looks to me ARM target has two issues on IFUNC support.
1 Sometimes STT_GNU_IFUNC symbols haven't gone through PLT.
We force STT_GNU_IFUNC to go through PLT to workaround the relocation
order issue by utilizing lazy relocation.
This is the issue caused the segment fault in this PR.
2 IRELATIVE should be put in the last in .rel.plt.
This is a further improvement we should done after issue 1 addressed.
Simliar improvement has been done on x86 by PR13302.
To fix this PR, we need to fix issue 1 first. So this PR is not purely a
duplicate of PR13302 which only caused by issue 2.
