Yeah, I see this comment in print_attributes:
/* GNU style tags have either a uleb128 value,
when lowest bit is not set, or a string
when the lowest bit is set.
"compatibility" (32) is special. It has
both a string and a uleb128 value. For
non-gnu we assume 6 till 31 only take ints.

Maybe we need a flag in the backend to tell whether attributes follow
the "gnu_vendor" convention? So that could be checked at:
bool gnu_vendor = (q - name == sizeof "gnu"
&& !memcmp (name, "gnu", sizeof "gnu"));
gnu_vendor |= ebl->has_gnu_attributes;
Or something similar?
Cheers,
Mark
