ctfconvert —
convert debug data to CTF data
  
    | ctfconvert | [ -gis]-llabel-Llabelenv [-ooutfile] object_file | 
The ctfconvert utility converts debug information from a
  binary file to CTF data and replaces the debug section of that file with a CTF
  section called SUNW_ctf. This new section is added to the input file, unless
  the -o option is present. You can also opt to keep the original debugging
  section with the -g option.
The following options are available:
  - -llabel
- Sets the label as label.
- -Llabelenv
- Instructs ctfconvertto read the label from the
      environment variable labelenv.
- -g
- Don't delete the original debugging section.
- -i
- Ignore object files built from other languages than C.
- -s
- Use the .dynsym ELF section instead of the .symtab ELF section.
- -ooutfile
- Write the output to file in outfile.
Thectfconvert utility exits 0 on success,
  and >0 if an error occurs.
The ctfconvert utility first appeared in
  FreeBSD 7.0.
The CTF utilities came from OpenSolaris.
