  18 # This test was added to test GDB's ability to backtrace over a large
  19 # stack frame for which there is no debug information.  This should
  20 # test the non-DWARF stack unwinder.
  21 #
  22 # The test was originally added for Risc-V where this case caused a
  23 # problem at one point, however, there's nothing Risc-V specific in
  24 # the test.
