  23 # Modified to test gdb's handling of separate debug info files.

  25 # This file has two parts. The first is testing that gdb behaves
  26 # normally after reading in an executable and its corresponding
  27 # separate debug file. The second moves the .debug file to a different
  28 # location and tests the "set debug-file-directory" command.

  52 # 'info source') and then see if the debug info is stabs. If so, we

  54 # finds out the debug format using gdb itself, and in case of stabs we
  55 # get an error loading the program if it is already stripped.  An
  56 # alternative would be to find out the debug info from the flags
