binutils-gdb/gdb/wrapper.h
Jim Ingham 73a93a3251 2000-03-13 James Ingham <jingham@leda.cygnus.com>
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.
