Deleting things often left measurements behind. Fixed these bugs, enhanced %del
to also delete frames and items in other frames than the current one, and added the corresponding regression tests. - fpd.y, README: %del can now also delete frames - test/del_frame: regression test for frame deletion - fpd.y: moved all debug items into debug_item, so that they can be invoked after defining measurements - README: clarified that object labels aren't entirely hidden in the GUI - delete.c (delete_references): also delete measurements referencing the frame (test/del_frame) - fpd.y (dbg_link_frame): described why we need base_frame in addition to base_vec - fpd.y, README: %del can now also reach into frames other than the current one - delete.c (do_delete_vec): also delete references in the root frame, i.e., measurements (tests/del_vec) git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5947 99fdad57-331a-0410-800a-d7fa5415bdb3

For debugging and regression tests, fped supports the following commands,

most of which mimick the effect of GUI operations:

%del <identifier>

%del <qualified-identifier>

|

%del and %move take as their first argument the name of the vector or
|
||||
object to manipulate. For this purpose, also objects can be labeled.
|
||||
%del removes the specified item. This can be a vector, an object, or
|
||||
a frame. If the vector or object is in a different frame than the
|
||||
current, its name is qualified with the frame name, e.g., "foo.obj".

Object labels behave like vector labels and share the same name space.
|

They are not shown anywhere in the GUI.
|
||||
For this purpose, also objects can be labeled. Object labels behave like
|
||||
vector labels and share the same name space. They are not normally
|
||||
accessible in the GUI. (You can see them in the code view.)
|
||||
|
||||
%move sets an anchor point to the vector named as its last argument.

The anchor point is identified by index as follows:
