and @code{jit-reader-unload} commands.
@table @code
@item jit-reader-load @var{reader-name}
Load the JIT reader named @var{reader-name}. On a UNIX system, this
will usually load @file{@var{libdir}/gdb/@var{reader-name}}, where
@var{libdir} is the system library directory, usually
@file{/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 @value{GDBN} reporting an error. A new JIT reader can be loaded by
first unloading the current one using @code{jit-reader-load} and then
invoking @code{jit-reader-load}.
@item jit-reader-load @var{reader}
Load the JIT reader named @var{reader}. @var{reader} is a shared
object specified as either an absolute or a relative file name. In
the latter case, @value{GDBN} will try to load the reader from a
pre-configured directory, usually @file{@var{libdir}/gdb/} on a UNIX
system (here @var{libdir} is the system library directory, often
@file{/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 @value{GDBN}
reporting an error. A new JIT reader can be loaded by first unloading
the current one using @code{jit-reader-unload} and then invoking
@code{jit-reader-load}.
@item jit-reader-unload
Unload the currently loaded JIT reader.
