gst2ascii - Filter and output Atari program symbol table as ASCII

       Written by Eero Tamminen <oak at helsinkinet fi>.

gst2ascii  reads symbol table from the given Atari program, and outputs it in the ASCII format understood
       by the Hatari debugger and its profiler data post-processor.  Symbol tables in the  traditional  DRI/GST,
       GNU a.out and new GCC PRGELF formats are supported.

       All  symbol  addresses output by the tool are TEXT relative, so when loading them in Hatari debugger, one
       needs to give just TEXT as offset for the 'symbols' command.

       There are some options for filtering the symbol table content, and the resulting ASCII output is easy  to
       edit  also  by  hand,  in  case  other  symbols (e.g. loop labels) need to be removed from it, or missing
       function symbols need to be added to it.

       Save 'program.prg' symbol table in ASCII format with local symbols filtered out:
            gst2ascii -l program.prg > program.sym

       Load generated ASCII symbols file in Hatari debugger:
            symbols program.sym TEXT DATA BSS

       If you have problems, try with 'nm -n <program>' instead (Atari native or cross-compiler version). If  nm
       works, but gst2ascii does not, please report a bug on it.

-a     Filter absolute (= value, not address) symbols out from the output.

       -b     Filter BSS symbols out from the output.

       -d     Filter DATA symbols out from the output.

       -f     Filter (object) file/path name symbols out from the output.

       -g     Filter GCC internal (object) symbols out from the output.

       -l     Filter local (.L*) symbols out.  Normally they are useless because they do not  have  names,  just
              numbers.

       -n     Sort symbol output by symbol names, not by their addresses.

       -s     Filter out symbols with duplicate addresses from the output.

       -t     Filter TEXT symbols out from the output.

       -w     Filter weak symbols out from the output.

       By  default,  same  filter  options  are enabled as in Hatari debugger.  Prefixing option letter with '+'
       instead of '-', keeps the indicated symbol type, if that type was disabled in the tool defaults (or by an
       option given earlier on the command line).
