| 22 | # This file used to have two copies of the tests with different |
| 23 | # compiler flags for hp-ux. Instead, the user should set CXXOPTS |
| 24 | # or run runtest with --target_board unix/gdb:debug_flags="..." |
| 25 | # to choose the compiler flags. |
| 26 | # |
| 27 | # The interesting compiler flags are: "aCC +A -Wl,-a,-archive" . |

| 29 | # address of the notification hook in the C++ support library. |
