| |
| <p><small>GDB</small> provides two mechanisms for automatically loading extensions |
| when a new object file is read (for example, due to the <code>file</code> |
| command, or because the inferior has loaded a shared library): |
| <samp><var>objfile</var>-gdb.<var>ext</var></samp> and the <code>.debug_gdb_scripts</code> |
| section of modern file formats like ELF. |

| <p>The auto-loading feature is useful for supplying application-specific |
| debugging commands and features. |
| </p> |
| <p>Auto-loading can be enabled or disabled, |
| and the list of auto-loaded scripts can be printed. |
| See the ‘<samp>auto-loading</samp>’ section of each extension language |
| for more information. |
| For <small>GDB</small> command files see <a href="Auto_002dloading-sequences.html#Auto_002dloading-sequences">Auto-loading sequences</a>. |
| For Python files see <a href="Python-Auto_002dloading.html#Python-Auto_002dloading">Python Auto-loading</a>. |
| </p> |
| <p>Note that loading of this script file also requires accordingly configured |
| <code>auto-load safe-path</code> (see <a href="Auto_002dloading-safe-path.html#Auto_002dloading-safe-path">Auto-loading safe path</a>). |
