Sure. So I would point you to the IPA ICF pass, which makes merging
of variables in WPA phase of LTO. Let's take a look at:
ipa-icf.c:1839 (sem_variable::equals) where
we do:
if (DECL_INITIAL (decl) == error_mark_node && in_lto_p)
dyn_cast <varpool_node *>(node)->get_constructor ();
That's the way how load DECL_INITIAL of variables.
Does it help you?
