Next: Writing JIT Debug Info Readers, Up: Custom Debug Info [Contents][Index]
Readers can be loaded and unloaded using the
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
Unload the currently loaded JIT reader.
