21# Based on break.exp, written by Rob Savoye. (rob@cygnus.com)
22# Modified to test gdb's handling of separate debug info files.
23
24# This file has two parts. The first is testing that gdb behaves
25# normally after reading in an executable and its corresponding
26# separate debug file. The second moves the .debug file to a different
27# location and tests the "set debug-file-directory" command.
