/* A major contribution to object and executable size is debug

   information size.  A major contribution to debug information size

   is struct descriptions replicated in several object files. The

   following flags attempt to reduce this information.  The basic

   idea is to not emit struct debugging information in the current

   compilation unit when that information will be generated by

   another compilation unit.

   Debug information for a struct defined in the current source

   file should be generated in the object file.  Likewise the

   debug information for a struct defined in a header should be

   generated in the object file of the corresponding source file.

   Both of these case are handled when the base name of the file of

   the struct definition matches the base name of the source file

   of the current compilation unit.  This matching emits minimal

   struct debugging information.

   The base file name matching rule above will fail to emit debug

   information for structs defined in system headers.  So a second

   category of files includes system headers in addition to files

   with matching bases.

   The remaining types of files are library headers and application

   headers.  We cannot currently distinguish these two types.  */
