ipa.c (symbol_table::remove_unreachable_nodes): Mark all inline clones as having abstract origin used.
* ipa.c (symbol_table::remove_unreachable_nodes): Mark all inline clones
as having abstract origin used.
* ipa-inline-transform.c (can_remove_node_now_p_1): Drop abstract origin check.
(clone_inlined_nodes): Copy abstract originflag.
* lto-cgraph.c (compute_ltrans_boundary): Use get_create to get abstract origin node.
