--- Comment #18 from Alan Modra <amodra at gmail dot com> ---
Isn't this a bug in the assembly?  We've changed the ABI, there is no way
anyone can expect all old asm to work with power10 pcrel.  To support pcrel you
need new asm.

#ifdef __PCREL__
__asm__ (pcrel version);
#else
__asm__ (non-pcrel version);
#endif

No need for special constraints, I think.  (And not sufficient if we had them.)
