--- Comment #1 from Vladimir Makarov <vmakarov at gcc dot gnu.org> ---
LRA does not update elimination offset on subsequent passes as insns for
previous elimination offset updates are more complicated on s390 than usual.
I guess we need a different elimination approach (without parsing already
generated offset elimination insn) independent on insns generated. It is
necessary not only for s390 but for better LRA portability in whole.
I hope to finish this until end of the week.
