I don’t think so?

Gotcha! They are all R_390_RELATIVE except for:
00045ff0 00110016 R_390_64 00042c58 u_ops + 70

Hi,
in static-pie, relocations get processed in _start, before main() is

instead of crt1.o. And that file processes all relative relocations. You
can check with readelf -r what the relocation types are. If they are not
relative,
