21 | # This file has two parts. The first is testing that gdb behaves | |
22 | # normally after reading in an executable and its corresponding | |
23 | # separate debug file. The second moves the .debug file to a different | |
24 | # location and tests the "set debug-file-directory" command. | |
4935890f JK |
25 | # The third is for testing build-id retrievel by finding the separate |
26 | # ".debug-id/ab/cdef.debug" file. | |
