 *** Changes since GDB 6.8
 
+* GDB now has an interface for JIT compilation.  Applications that
+dynamically generate code can create symbol files in memory and register
+them with GDB.  For users, the feature should work transparently, and
+for JIT developers, the interface is documented in the GDB manual in the
+"JIT Compilation Interface" chapter.

 * Tracepoints may now be conditional.  The syntax is as for
 breakpoints; either an "if" clause appended to the "trace" command,
 or the "condition" command is available.  GDB sends the condition to

 with the `remote:' prefix, either via the `set sysroot' command or via

+* "info sharedlibrary" now takes an optional regex of libraries to show,
+and it now reports if a shared library has no debugging information.

 * Commands `set debug-file-directory', `set solib-search-path' and `set args'

+catch syscall [NAME(S) | NUMBER(S)]
+  Catch system calls.  Arguments, which should be names of system
+  calls or their numbers, mean catch only those syscalls.  Without
+  arguments, every syscall will be caught.  When the inferior issues
+  any of the specified syscalls, GDB will stop and announce the system
