#### 30.4.1 Using JIT Debug Info Readers ¶

Readers can be loaded and unloaded using the `jit-reader-load` and `jit-reader-unload` commands.

`jit-reader-load reader`

  Load the JIT reader named reader, which is a shared object specified as either an absolute or a relative file name. In the latter case, GDB will try to load the reader from a pre-configured directory, usually `libdir/gdb/` on a UNIX system (here libdir is the system library directory, often `/usr/local/lib`).

  Only one reader can be active at a time; trying to load a second reader when one is already loaded will result in GDB reporting an error. A new JIT reader can be loaded by first unloading the current one using `jit-reader-unload` and then invoking `jit-reader-load`.

`show jit-reader-directory`

  This command will show the directory that is used by `jit-reader-load` when a relative file name is specified.

`jit-reader-unload`

  Unload the currently loaded JIT reader.
