Hi!
The early-debug changes moved warnings about unused functions into cgraph.
The problem is that if we have just unused declarations, they aren't
sometimes even registered with cgraph and therefore we no longer warn.
Here is an attempt to register those with cgraph anyway to get the warning,
for C FE only (no idea where to do that in C++ FE). Or anyone has better
suggestions what to do?
Bootstrapped/regtested on x86_64-linux and i686-linux.

You mean check if it has a cgraph node (i.e. get instead of get_create) and
if it doesn't, warn? What I'm worried in that case is that it might have a
cgraph node created later on for whatever reason and that we'll get double
warning (from here and from cgraphunit.c (check_global_declaration)).
I can try it though.

No, simply warn and set TREE_NO_WARNING so cgraph doesn't warn again.

Do we need to check both DECL_INITIAL and DECL_EXTERNAL?

Dunno, but that is what cgraphunit.c does, c-decl.c too,
what the old toplev.c (check_global_declaration_1) did (back to at least
r26593 from ~ 1999), so I think we want some consistency.
Either it is needed, or if it is not needed, then all the spots should
change, not just this one.
I can try to stick there an assert whether for FUNCTION_DECL
(DECL_INITIAL (decl) == 0) == DECL_EXTERNAL (decl).

Tried that, but cancelled that quickly, I see lots of cases where
DECL_INITIAL is non-NULL, but DECL_EXTERNAL is set, and some
where DECL_INITIAL is NULL, and DECL_EXTERNAL is not set,
at least in the other two spots (check_global_declaration in cgraphunit.c
and c-decl.c). Haven't waited long enough to find out if the C++ FE is some
exception.
