Consider this program: struct Base { typedef int value_type; }; struct Derived : public Base { value_type x; }; Derived d; Derived::value_type v; Compile this with '-g -c' and run gdb on the .o. Now some type lookups work, but some do not: (gdb) ptype Derived::value_type type = int (gdb) p (Derived::value_type *) 0 A syntax error in expression, near `) 0'. (gdb) p (Base::value_type *) 0 A syntax error in expression, near `) 0'. (gdb) python print gdb.lookup_type('Derived::value_type') Traceback (most recent call last): File "<string>", line 1, in <module> RuntimeError: No type named Derived::value_type. Error while executing Python code. (gdb) python print gdb.lookup_type('Base::value_type') Base::value_type
CVSROOT: /cvs/src Module name: src Changes by: kseitz@sourceware.org 2012-11-16 20:54:30 Modified files: gdb : ChangeLog cp-namespace.c gdb/testsuite : ChangeLog gdb/testsuite/gdb.cp: derivation.exp derivation.cc Added files: gdb/testsuite/gdb.cp: baseenum.cc baseenum.exp Log message: PR c++/13615 * cp-namespace.c (cp_lookup_symbol_in_namespace): Add SEARCH parameter and pass it to lookup_symbol_file. (cp_lookup_symbol_imports): Tell cp_lookup_symbol_in_namespace to search base classes. (cp_lookup_symbol_namespace): Likewise. (lookup_namespace_scope): Likewise. (lookup_symbol_file): Add SEARCH parameter. If SEARCH is non-zero and no symbol is found, lookup the class and call cp_lookup_nested_symbol. (find_symbol_in_baseclass): New function. (cp_lookup_nested_symbol): Do not let cp_lookup_symbol_in_namespace search through base classes. Do that later when there is no global symbol match. PR c++/13615 * gdb.cp/baseenum.cc: New file. * gdb.cp/baseenum.exp: New file. * gdb.cp/derivation.cc (A): Add copyright. Add a typedef. (B): Use A::value_type instead of int. Change all references. (D): Use value_type instead of int. Change all references. (E): Likewise. (F); Likewise. (Z): New class. (ZZ): New class. (N, Base, Derived): New namespace and classes. (main): Add instances of Z and ZZ. Make sure all symbols from N are kept. * gdb.cp/derivation.exp: Update typedef changes in tests. Add tests for class typedefs both before and after starting the inferior. Add tests for searching for a typedef while stopped in a method.
