Let's declare it fixed. It will pop up sooner or later if it is still latent.

Does it make sense to commit the patch from comment 17 (or comment 18)
nonetheless?

Huh, yes - I assumed that had been fixed. Segher? Can you please fix that GTY

Let me clarify: I cannot reproduce that ICE from comment 5 as well, but
probably because of the same underlying reason that "fixed" the ICE from
comment 0.

I'll look at it. It's over three years old, will need some testing etc.

The issue is that the decls are inside
#ifdef RS6000_GLIBC_ATOMIC_FENV
...
#endif
but gengtype will unconditionally register the root, refering to the variables.
I suggest to remove the #ifdef guard and instead wrap the decls inside
#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wunused"
..
#pragma GCC idagnostic pop
The C++ FE doesn't seem to allow ATTRIBUTE_UNUSED anywhere here and I guess
"fixing" gengtype isn't a thing you want to do ;)

rs6000: Fix GC on rs6000.c decls for atomic handling (PR88134)
In PR88134 it is pointed out that we do not have GTY markup for some
variables we use for atomic. So, let's add that.

PR target/88134
* config/rs6000/rs6000.cc (atomic_hold_decl, atomic_clear_decl,
atomic_update_decl): Add GTY markup.
