| 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. | |

| 51 | # To do this we must run gdb on the unstripped executable, list 'main' | |

| 53 | # 'info source') and then see if the debug info is stabs. If so, we | |

| 55 | # finds out the debug format using gdb itself, and in case of stabs we | |
| 56 | # get an error loading the program if it is already stripped. An | |
| 57 | # alternative would be to find out the debug info from the flags | |
| 58 | # passed to dejagnu when the test is run. | |
