            Bug ID: 24419
           Summary: stap -l 'process("p")statement ("func@file:N")
                    sometimes displays relative paths
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: translator
          Assignee: systemtap at sourceware dot org
          Reporter: scox at redhat dot com
  Target Milestone: ---

subdirectory paths are sometimes displayed as relative with
statement("function@file:line") probes.  e.g.

("tracing_backend_handle_arg@/work/scox/strace/scoxsrc/tracing_backend.h:159")
versus
("gdb_handle_arg@gdbserver/gdbserver.c:1280")

dwflpp.cxx::dwflpp::collect_srcfiles_matching needs to do something similar to
below to get pp() to return statement("func@/path/to/subdir/file.c:N") instead
of current "func@subdir/file.c:N"

      char const *fname = dwarf_diename (die);
      if (fname != NULL)
        {
          if (fname[0] != '/')
            {
              /* Relative path, get CU comp_dir.  This is really too generic,
                 because we know this is the CU die already... */
              const char *fdir;
              Dwarf_Die cudie;
              Dwarf_Attribute cdattr;
              fdir = dwarf_formstring (dwarf_attr (dwarf_diecu (die,
                                                                &cudie,
                                                                NULL,
                                                                NULL),
                                                   DW_AT_comp_dir,
                                                   &cdattr));
              check_it (fdir == NULL, "dwarf_formstring comp_dir");
              printf ("### %s/%s\n", fdir, fname);
            }
          else
            printf ("### %s\n", fname);
        }
        off = noff;
     }
