I think it is the new:
3384 if (TREE_STATIC (var) && !TREE_ASM_WRITTEN (var))
3385 {
3386 if (var_ann (var) && referenced_var_check_and_insert (var))
3387 cfun->local_decls = tree_cons (NULL_TREE, var,
3388 cfun->local_decls);
3389 }
that causes this. Compared to add_referenced_var this doesn't do the:
/* Scan DECL_INITIAL for pointer variables as they may contain
address arithmetic referencing the address of other
variables.
Even non-constant initializers need to be walked, because
IPA passes might prove that their are invariant later on. */
if (DECL_INITIAL (var)
/* Initializers of external variables are not useful to the
optimizers. */
&& !DECL_EXTERNAL (var))
walk_tree (&DECL_INITIAL (var), find_vars_r, NULL, 0);
part. So, either tree-inline.c needs to do the same, or it can't use
referenced_vars bit as a test whether it has been queued already onto
local_decls or not. Honza?
