 296         Is_Read, Is_Write.  Add attribute Save_Invocation_Graph_Of_Body
 297         and update its occurrence in nodes.

1067         * lib-writ.adb (Write_With_Lines): Modfiy the generation
1068         of dependencies within ali files so that source unit
1069         bodies are properly listed even if said bodies are
1070         missing.  Perform legacy behavior in GNATprove mode.
1071         * lib-writ.ads: Modify documentation to reflect current
1072         behavior.

1077         * lib-writ.adb, lib-writ.ads (Write_With_Lines): Add
1078         documentation and an extra conditional check for RCI
1079         units so that generated ali files will list the spec
1080         only instead of a body when a body is not found.
