 # TODO
 
-- Add tests for references of marks with all supported addressing modes.
+- Automatically export functions, i.e. all marks with CALL xref have to have the
+  following preamble:
+
+```
+
+  .global L000015de
+  .type	L000015de, @function
+```
+
 - Implement CLI option that can be used to specify regions of RAM and IO
   registers. Custom ROM location and size is still not the case, only 4MiB at
   the base `0x00000000` is supported and it remains.
