       1)

       2) Equivalent to print_ustack(ubacktrace), except that deeper stack nesting may be supported. Returns
       nothing. See print_backtrace for kernel backtrace.

       Equivalent to print_ubacktrace, but it performs the backtrace using the pc, sp, and fp provided. Useful

NOTE

       To get (full) backtraces for user space applications and shared shared libraries not mentioned in the
       current script run stap with -d /path/to/exe-or-so and/or add --ldd to load all needed unwind data.
