Yes, exactly. Silently giving any handling to reserved values will never end well; just a warning would help a lot already (making it non-silent :-) ) FWIW, calling this "POWER10 ABI" is very inexact; it is just part of the ELFv2 ABI (a reserved value in older ABI versions, and with a specific meaning in newer versions), not only for Power10. Of course it was created to make code that uses pcrel addressing faster, but :-)
