By the way Jason, is there any reason we previously called
equate_decl_number_to_die() only for abstract instances?:


So that multiple concrete instances can find the abstract instance.


Ah, I see.


Why isn't DECL_ABSTRACT_P set the first time you get here for the label
in question?

Oh, that part was working fine. The testcase that prompted this wholething had nothing to do with DECL_ABSTRACT_P. I was just curious if Icould remove the call to equate_decl_number_to_die, but I see it's needed.

I don't see anything else in dwarf2out.c doing a
lookup_decl_die() on a LABEL_DECL, so I don't even know why the
equate_decl_number_to_die() is even there.


add_abstract_origin_attribute uses lookup_decl_die.


Thanks.
