             Bug #: 13615
           Summary: inherited typedefs not found properly
           Product: gdb
           Version: unknown
            Status: NEW
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned@sourceware.org
        ReportedBy: tromey@redhat.com
    Classification: Unclassified


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

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.
