# Modified to test gdb's handling of a debug-id retrieval.

# This file has two parts. The first is testing that gdb behaves
# normally after reading in an executable and its corresponding
# separate debug file. The second moves the .debug file to a different
# location and tests the "set debug-file-directory" command.
# The third is for testing build-id retrievel by finding the separate
# ".debug-id/ab/cdef.debug" file.
