From the gnu (.dvi :-) manual:

	`-gg' Produce debugging information in GDB's own format. This requires
the GNUassembler and linker in order to work.

   `sym-ld.ttp' is a special version of the linker. Its sole purpose is to
create a special symbol file used by the GNUdebugger. The following example
shows the usage.(`$' is the prompt of a CLI, `*' is the GDB prompt, `#' marks
a comment)
 
     $ gcc -c -gg foo.c    # compile `foo.c'
     $ gcc -o foo.prg foo.o # linkwith normal `gcc-ld.ttp'
     $ sym-ld  -r -o foo.sym $(GNULIB)"crt0.o foo.o -lgnugdb  (or -lgdb)
                           # link with `sym-ld.ttp' to get symbol file
     $ gdb
     * exec-file foo.prg   # executable (`gcc-ld.ttp' linked Atari
                             executable)
     * symbol-file foo.sym  # symbols file (`sym-ld.ttp' `-r -o' linked)
     * run
     * <start doing gdb commands here>
      : : :
     * q
     $                     # back
 
 
   Note the line in the example, where `sym-ld.ttp'is invoked. A library
`gnugdb.olb' is used to create the symbol file. This is just like the normal
library `gnu.olb' except that is was compiled.
