programmers working on compilers and debuggers (and any one

developed by a committee (known as the PLSIG at the time)

starting around 1991. Starting around 1991 SGI developed the

libdwarf and dwarfdump tools for internal use and as part of

SGI IRIX developer tools. Since that time dwarfdump and

libdwarf have been shipped (as an executable and archive

respectively, not source) with every release of the SGI
