* ipa-devirt.c (odr_type_d): Add field all_derivations_known. (type_all_derivations_known_p): New predicate. (type_all_ctors_visible_p): New predicate. (type_possibly_instantiated_p): New predicate. (get_odr_type): Compute all_derivations_known. (dump_odr_type): Dump the flag. (maybe_record_type): Cleanup. (record_target_from_binfo): Add bases_to_consider array; record bases for types w/o instances and skip CXX destructor. (possible_polymorphic_call_targets_1): Add bases_to_consider and consider_construction parameters; check if type may have instance. (get_polymorphic_call_info): Set maybe_in_construction to true when we know nothing. (record_targets_from_bases): Skip CXX destructors; they are never called for types in construction. (possible_polymorphic_call_targets): Do not record target when type may not have instance. * g++.dg/ipa/devirt-31.C: New testcase. From-SVN: r209461
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
