------- Comment #14 from jakub at gcc dot gnu dot org 2006-04-20 12:04 -------
The reversal of the DECL_UID (x) = DECL_UID (t); assignment in name-lookup.c
causes
FAIL: g++.dg/opt/inline2.C (test for excess errors)
as well as
// { dg-do link }
// { dg-options "-O1" }
static int g;
void f()
{
extern int g;
g++;
}
int main () {
f ();
}
regression.
For some of the duplicate decls in different binding levels I'm pretty sure we
could just duplicate_decls instead of keeping two decls around, but as the
comment explains e.g. for
static int g (int x, int y = 8);
void f ()
{
int g (int x, int y = 12);
g (6);
}
int g (int x, int y)
{
return x + y;
}
int main ()
{
f ();
g (6);
}
we need two decls, at least throughout the frontend. On the other side, the
two
decls are really supposed to share all cgraph {,varpool} node properties,
except
the decl itself (and uid), so I wonder if we couldn't have indirect nodes in
cgraph_hash and cgraph_varpool_hash or something similar for this purpose.
