#### 29.4.1 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-name
  Load the JIT reader named reader-name. On a UNIX system, this will usually load `libdir/gdb/reader-name`, where libdir is the system library directory, usually `/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-load` and then invoking `jit-reader-load`.
`jit-reader-unload`
  Unload the currently loaded JIT reader.
