| <h5 class="subsubsection">23.2.3.2 The <code>.debug_gdb_scripts</code> section</h5> |
| |
| <p><a name="index-g_t_0040code_007b_002edebug_005fgdb_005fscripts_007d-section-1948"></a> |
| For systems using file formats like ELF and COFF, |
| when <span class="sc">gdb</span> loads a new object file |
| it will look for a special section named ‘<samp><span class="samp">.debug_gdb_scripts</span></samp>’. |
| If this section exists, its contents is a list of names of scripts to load. |
| |
| <p><span class="sc">gdb</span> will look for each specified script file first in the |
| current directory and then along the source search path |
| (see <a href="Source-Path.html#Source-Path">Specifying Source Directories</a>), |
| except that <samp><span class="file">$cdir</span></samp> is not searched, since the compilation |
| directory is not relevant to scripts. |
| |
| <p>Entries can be placed in section <code>.debug_gdb_scripts</code> with, |
| for example, this GCC macro: |
| |
| <pre class="example"> /* Note: The "MS" section flags are to remove duplicates. */ |
| #define DEFINE_GDB_SCRIPT(script_name) \ |
| asm("\ |
| .pushsection \".debug_gdb_scripts\", \"MS\",@progbits,1\n\ |
| .byte 1\n\ |
| .asciz \"" script_name "\"\n\ |
| .popsection \n\ |
| "); |
| </pre> |
| <p class="noindent">Then one can reference the macro in a header or source file like this: |
| |
| <pre class="example"> DEFINE_GDB_SCRIPT ("my-app-scripts.py") |
| </pre> |
| <p>The script name may include directories if desired. |
| |
| <p>If the macro is put in a header, any application or library |
| using this header will get a reference to the specified script. |
