This is a repost of the series at https://sourceware.org/pipermail/libc-alpha/2022-January/135598.html incorporating review comments. Changes are: - subject lines changed to comply with glibc commit log standards - patch 1/4 log now mentions making a couple of symbols hidden - patch 2/4 makes at_platform available to early ifunc resolvers as well as hwcap. - patch 3/4 log mentions stinfo->init and stinfo->fini being unused - patch 4/4 PI_STATIC_AND_HIDDEN comment explains what is going on patch 2/4 is the only code change from the previous series. Testsuite results now show no regressions on powerpc64le-linux. I haven't reposted the old patch 4/5 as it was just a side-issue I noticed when looking over relative relocations. https://sourceware.org/pipermail/libc-alpha/2022-January/135603.html I think it qualifies as an obvious patch so will commit it separately from this series.
