I've become a little rusty on the x86 target code but it looks OK to me. The simple approach that HJ has taken is quite suited to a release branch, as compared to redesigning x86_64 ifunc support.. (The latter might be preferable on mainline to avoid the reloc scanning, if possible, but I leave that decision to HJ.) -- Alan Modra Australia Development Lab, IBM
