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. | |
