Hi,
this patch solves the actual ICE in PR59831 by using ipa-devirt instead of
gimple_extract_devirt_binfo_from_cst as discussed in the first post.

PR ipa/59831
* ipa-cp.c (ipa_get_indirect_edge_target_1): Use ipa-devirt
to figure out targets of polymorphic calls with known decl.
* ipa-prop.c (try_make_edge_direct_virtual_call): Likewise.
* ipa-utils.h (get_polymorphic_call_info_from_invariant): Declare.
* ipa-devirt.c (get_polymorphic_call_info_for_decl): Break out from ...
(get_polymorphic_call_info): ... here.
(get_polymorphic_call_info_from_invariant): New function.
* g++.dg/ipa/devirt-22.C: New testcase.
Today I'm seeing regressions in the libstdc++-v3 testsuite in the form
of ICEs exactly in ipa_get_indirect_edge_target_1:

Can you please have a look?
Thanks,
