Using JIT Debug Info Readers - Debugging with GDB

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. reader 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.
jit-reader-unload: Unload the currently loaded JIT reader.
