(varobj_get_frozen): New.
(varobj_update): New parameter explicit.
* varobj.c (struct varobj): New fields frozen
and not_fetched.
(varobj_set_frozen, varobj_get_frozen): New.
(install_new_value): Don't fetch values for
frozen variable object, or children thereof. Allow
a frozen variable object to have non-fetched value.
(varobj_update): Allow updating child variables.
Don't traverse frozen children.
(new_variable): Initialize the frozen field.
(c_value_of_variable): Return NULL for frozen
variable without any value yet.
* mi/mi-cmd-var.c (varobj_update_one): New parameter
'explicit'.
(mi_cmd_var_create): Output the 'frozen' field,
as soon as testsuite is adjusted to expect that field.
(mi_cmd_var_set_frozen): New.
(mi_cmd_var_update): Pass the 'explicit' parameter to
varobj_update_one.
* mi/mi-cmds.c (mi_cmds): Register '-var-set-frozen'.
* mi/mi-cmds.h (mi_cmd_var_set_frozen): Declare.
* varobj.h (enum varobj_update_error): New enum.
* varobj.c (struct varobj_root): Add is_valid member.
(varobj_get_type): Check for invalid varobj.
(varobj_get_attributes): Likewise.
(variable_editable):Likewise.
(varobj_update): Likewise. Use varobj_update_error.
(new_root_variable): Set root varobj as valid by default.
(varobj_invalidate): New function.
* symfile.c (clear_symtab_users): Use varobj_invalidate.
* mi/mi-cmd-var.c (varobj_update_one): Change return type to void.
Use varobj_update_error.

* mi/mi-cmds.h (mi_no_values, mi_simple_values, mi_all_values): New
declarations.
* mi/mi-cmd-stack.c (mi_cmd_stack_list_locals): Use string
constants instead of literals for MI command options.
* mi/mi-cmd-var.c (mi_no_values, mi_simple_values, mi_all_values):
New variables.
(mi_parse_values_option, mi_print_value_p): New functions.
(mi_cmd_var_list_children): Use mi_parse_values_option and
mi_print_value_p.
(mi_cmd_var_update): Support a PRINT_VALUES option. Update calls
to varobj_update_one.
(varobj_update_one): Take a print_values argument. Call
mi_print_value_p.
* varobj.c (varobj_get_gdb_type): New function.
* varobj.h (varobj_get_gdb_type): New prototype.
pointer to struct varobj*. This function can delete
varobjs, so we need to give callers the new varobj
when this happens.
(value_of_root): Update "var", too, if "var_handle"
changes.
* varobj.h (varobj_update): Likewise.
Add support for a variable object that tries to evaluate itself in
the currently selected frame, rather than in a fixed frame.
* wrapper.c,h (gdb_parse_exp_1): Added a wrapper for
gdb_parse_exp_1.
* varobj.h: Added USE_CURRENT_FRAME to varobj_type & changed def'n
of varobj_create.
* varobj.c (varobj_list): Return type indicates whether the
variable's type has changed (for current frame variables).
(varobj_update): Handle the case where the variable's type has
changed.
(delete_variable_1): Allow for deletion of variables that have not
been installed yet.
(new_root_variable): Initialize use_selected_frame variable.
(value_of_root): This is where most of the work to handle "current
frame" variables was added. Most of the complexity involves
handling the case where the type of the variable has changed.
(varobj_create): Add a "type" argument, to tell if the
variable is one of these "current frame" variables. Also protect
call to parse_exp_1 from long jumping.
* mi-var-block.exp: The error report from varobj_create changed
since I am now trapping parse_exp_1 errors. Change the tests to
match the new error message.
* mi-var-child.exp: Ditto.
* mi-var-cmd.exp: Ditto.
* lib/gdb.exp: Fix the gdbtk_start routine to correctly find all
the library directories.
* gdbtk-varobj.c (variable_create): Pass the correct
"how_specified" flag to the varobj_create routine.
