Thanks, -- Joel commit 3bd5c92a7f98feac47612559b60b64fae4e699d5 Author: Joel Brobecker Date: Tue Dec 13 15:24:53 2011 -0500 Use symbol search name in expand_symtabs_matching_via_partial... We are iterating over all symbols in a partial symtab that would match a given name, so we should match the partial symbols search name against the given name rather than using the natural name. In C++, that does not make a difference, but it does in Ada, because Ada searches using the symbol encoded name... We also update the generation of the .gdb_index file to match this change in the search. Although technically an incompatible change, we do not increment the gdb_index version number, because Ada is the only language where it would make a difference - except that this feature is not supported for Ada. gdb/ChangeLog: * psymtab.c (expand_symtabs_matching_via_partial): Match the partial symbols using their SYMBOL_SEARCH_NAME. * symfile.h (struct quick_symbol_functions): Udate the documentation of expand_symtabs_matching. * dwarf2read.c (write_psymbols): Use SYMBOL_SEARCH_NAME instead of SYMBOL_NATURAL_NAME in index entry. diff --git a/gdb/psymtab.c b/gdb/psymtab.c index 74185cc..861b302 100644 --- a/gdb/psymtab.c +++ b/gdb/psymtab.c @@ -1305,7 +1305,7 @@ expand_symtabs_matching_via_partial || (kind == TYPES_DOMAIN && SYMBOL_CLASS (*psym) == LOC_TYPEDEF)) && (*name_matcher) (current_language, - SYMBOL_NATURAL_NAME (*psym), data)) + SYMBOL_SEARCH_NAME (*psym), data)) { PSYMTAB_TO_SYMTAB (ps); keep_going = 0; diff --git a/gdb/symfile.h b/gdb/symfile.h index 44f0c01..91605a2 100644 --- a/gdb/symfile.h +++ b/gdb/symfile.h @@ -263,10 +263,9 @@ struct quick_symbol_functions If even KIND matches, then NAME_MATCHER is called for each symbol defined in the file.
