2010-08-05 Martin Jambor <mjambor@suse.cz> * ipa-prop.h (enum ipa_lattice_type): Changed comments. (struct ipa_param_descriptor): New fields types and cannot_devirtualize. (ipa_param_cannot_devirtualize_p): New function. (ipa_param_types_vec_empty): Likewise. (ipa_make_edge_direct_to_target): Declare. * ipa-cp.c: Fixed first stage driver name in initial comment, described devirtualization there too. (ipcp_analyze_node): Call ipa_analyze_params_uses. (ipcp_print_all_lattices): Print devirtualization info. (ipa_set_param_cannot_devirtualize): New function. (ipcp_initialize_node_lattices): Set cannot_devirtualize when setting lattice to BOTTOM. (ipcp_init_stage): Merged into... (ipcp_generate_summary): ...its caller. (ipcp_change_tops_to_bottom): Also process type lists. (ipcp_add_param_type): New function. (ipcp_copy_types): Likewise. (ipcp_propagate_types): Likewise. (ipcp_propagate_stage): Also propagate types. (ipcp_need_redirect_p): Variable jump_func moved to its scope block. Also return true if propagated types require it. (ipcp_update_callgraph): Dump redirection info. (ipcp_process_devirtualization_opportunities): New function. (ipcp_const_param_count): Include known type information. (ipcp_insert_stage): Call ipcp_process_devirtualization_opportunities on new node. Fixed formatting. * ipa-prop.c (make_edge_direct_to_target): Renamed to ipa_make_edge_direct_to_target and changed all callers. Made externally visible. (ipa_node_duplication_hook): Duplicate types vector. * cgraphunit.c (cgraph_redirect_edge_call_stmt_to_callee): Also try to redirect outgoing calls for which we can't get a decl from the statement. Check that we can get a decl from the call statement. * ipa-inline.c (inline_indirect_intraprocedural_analysis): Call ipa_analyze_params_uses only when ipa-cp is disabled. * tree-inline.c (get_indirect_callee_fndecl): Removed. (expand_call_inline): Do not call get_indirect_callee_fndecl. * params.def (PARAM_DEVIRT_TYPE_LIST_SIZE): New parameter. * Makefile.in (ipa-cp.o): Add gimple.h to dependencies. * testsuite/g++.dg/ipa/devirt-1.C: New test. * testsuite/g++.dg/ipa/devirt-2.C: Likewise. * testsuite/g++.dg/ipa/devirt-3.C: Likewise. * testsuite/g++.dg/ipa/devirt-4.C: Likewise. * testsuite/g++.dg/ipa/devirt-5.C: Likewise. * testsuite/gcc.dg/ipa/iinline-3.c: Likewise.

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.
