ipa-cp: Avoid ICEs when looking at expanded thunks and unoptimized functions
2019-11-29 Martin Jambor <mjambor@suse.cz>
PR ipa/92476
* ipa-cp.c (set_single_call_flag): Set node_calling_single_call in
the summary only if the summary exists.
(find_more_scalar_values_for_callers_subset): Check node_dead in
the summary only if the summary exists.
(ipcp_store_bits_results): Ignore nodes without lattices.
(ipcp_store_vr_results): Likewise.
* cgraphclones.c: Include ipa-fnsummary.h and ipa-prop.h and the
header files required by them.
(cgraph_node::expand_all_artificial_thunks): Analyze expanded thunks.
