##### 23.2.3.1 The `objfile-gdb.py` file

When a new object file is read, gdb looks for a file named `objfile-gdb.py`, where objfile is the object file's real name, formed by ensuring that the file name is absolute, following all symlinks, and resolving `.` and `..` components. If this file exists and is readable, gdb will evaluate it as a Python script.

If this file does not exist, and if the parameter `debug-file-directory` is set (see Separate Debug Files), then gdb will look for real-name in all of the directories mentioned in the value of `debug-file-directory`.

Finally, if this file does not exist, then gdb will look for a file named `data-directory/python/auto-load/real-name`, where data-directory is gdb's data directory (available via `show data-directory`, see Data Files), and real-name is the object file's real name, as described above.

gdb does not track which files it has already auto-loaded this way. gdb will load the associated script every time the corresponding objfile is opened. So your `-gdb.py` file should be careful to avoid errors if it is evaluated more than once.
