2013-02-03 Jan Kratochvil <jan.kratochvil@redhat.com>
+ * dwarf2read.c (dw2_expand_symtabs_matching): Add basenames parameter
+ to the file_matcher parameter. Pass 0 to it.
+ (dwarf2_create_include_psymtab): Copy also DIRNAME.
+ * psymtab.c (partial_map_symtabs_matching_filename): Drop handling of
+ NULL psymtab_to_fullname result.
+ (psymtab_to_fullname): Remove variable r. Never return NULL, assemble
+ an expected filename instead.
+ (expand_symtabs_matching_via_partial): Add basenames parameter to the
+ file_matcher parameter. Call also psymtab_to_fullname, after newly
+ considering BASENAMES_MAY_DIFFER.
+ * source.c (rewrite_source_path): Remove static.
+ * source.h (rewrite_source_path): New declaration.
+ * symfile.h (struct quick_symbol_functions): Add basenames parameter to
+ the expand_symtabs_matching field. Comment it.
+ * symtab.c (file_matches): New function comment. Add parameter
+ basenames, implement it.
+ (search_symbols_file_matches): Add basenames parameter. Update the
+ file_matches caller.
+ (search_symbols): Match FILES also against symtab_to_fullname.
+ Optimize it for BASENAMES_MAY_DIFFER.
+
+2013-02-03 Jan Kratochvil <jan.kratochvil@redhat.com>
+
* source.c (print_source_lines_base): Print for TUI also "fullname".
* tui/tui-data.c (init_content_element): Change tui_locator_element
field to full_name.
