(gimple_fold_call): Declare. (gimple_adjust_this_by_delta): Likewise. * cgraph.c (cgraph_make_edge_direct): New parameter delta. Updated all users. (cgraph_clone_edge): Create a copy of indirect_info also for direct edges. * cgraphunit.c (cgraph_redirect_edge_call_stmt_to_callee): Adjust this parameters. * gimple-fold.c (gimple_fold_obj_type_ref_known_binfo): Renamed to gimple_get_virt_mehtod_for_binfo, new parameter delta. Do not search through thunks, in fact bail out if we encounter one, check that BINFO_VIRTUALS is not NULL. (gimple_adjust_this_by_delta): New function. (gimple_fold_obj_type_ref): Removed. (gimple_fold_obj_type_ref_call): New function. (fold_gimple_call): Renamed to gimple_fold_call, made external. Updated users. Call gimple_fold_obj_type_ref_call instead of gimple_fold_obj_type_ref. * ipa-cp.c (ipcp_process_devirtualization_opportunities): Process thunk deltas. (ipcp_discover_new_direct_edges): Likewise. * ipa-prop.c (ipa_make_edge_direct_to_target): New parameter delta. Updated callers. (ipa_write_indirect_edge_info): Stream thunk_delta. (ipa_read_indirect_edge_info): Likewise. * tree-ssa-ccp.c (ccp_fold_stmt): Use gimple_fold_call instead of gimple_fold_obj_type_ref. * testsuite/g++.dg/ipa/pr46053.C: New test. * testsuite/g++.dg/ipa/pr46287-1.C: Likewise. * testsuite/g++.dg/ipa/pr46287-2.C: Likewise. * testsuite/g++.dg/ipa/pr46287-3.C: Likewise. * testsuite/g++.dg/torture/covariant-1.C: Likewise. * testsuite/g++.dg/torture/pr46287.C: Likewise.
