  22 #         with OS/glibc/gdb dep
  23 #       then have a general way to delete uninteresting and vayring
  24 #         lines.
  25 #       suppress lines telling file _exit.c does not exist
  26 #       initial tty control character sent by gdb 7.0
  27 #       remove missing debuginfos
  28 #       vgdb message
  29 #       pid numbers

  34 #       delete Loaded symbols file lines
  35 #       delete language switch messages.
  36 #       remove gdb prompts.
  37 #       remove gdb continuation prompts.

  50 #       SIGFPE backtrace is varying so much that we just remove all lines
  51 #       after the signal trapping using an expr in this sed, followed by another sed.
  52 #       transform info thread of 7.3 into the layout of 7.2 and before.
  53 #       delete lines telling that some memory can't be accessed: this is
  54 #         a.o. produced by gdb 7.2 on arm (same with standard gdbserver)
  55 #       delete empty lines (the last line (only made of prompts) sometimes
  56 #           finishes with a new line, sometimes not ???).
  57 #       'exited with code' and 'exited normally' are printed slightly
  58 #       differently between gdb versions, normalize to "Program exited...".
