For globals we could track this properly by using the varpool nodes instead of
the DECL_UID to do disambiguation.
Queued.

Hm, I only can see references to "symbol" not to either function or variable
declaration in the documentation. Can you cite the part that makes you think
it restricts the use to functions?

Whoever designed this feature should be beaten with a cluebat for not asking
people on how this will interact with aliasing.
IMHO the testcase should be declared invalid and it should be documented that
an aliased o

I looked up 'weakref' in the GCC documentation because I'd forgotten exactly
what it was supposed to do, and noticed that it's actually documented as
applying only to functions. So, maybe we could just say that this

A weak alias is still an alias and still not supported by Mac

Make it a weak alias, then.
Anyhow, the point is that the alias infrastructure in GCC is available for all
ports. If some port limits what kinds of aliases you can use, then, well, too
bad. But the smarts to get al
