241 | Breakpoints to set at the beginning of the execution | |
242 | (each breakpoint demands its own -b option, e.g. -b foo -b bar) | |

244 | Environment variables to be set with 'exec-wrapper env' in GDB | |
245 | (each environment variable demands its own -e option, e.g. | |

250 | -c, --in-container | |
251 | Run the test case inside a container and automatically attach | |
252 | GDB to it. | |
253 | -i, --no-direct | |
254 | Selects whether to pass the --direct flag to the program. | |
255 | --direct is useful when debugging glibc test cases. It inhibits the | |
256 | tests from forking and executing in a subprocess. | |
257 | Default behaviour is to pass the --direct flag, except when the | |
258 | program is run with user specified arguments using the "--" separator. | |
259 | -s, --no-symbols-file | |
260 | Do not tell GDB to load debug symbols from the program. | |
