+commit bc7b765ab71f967eb2a9c3da111d7529eec46fbe
+Author: John Baldwin <jhb@FreeBSD.org>
+Date:   Sun Jul 3 11:56:21 2016 -0700
+
+    Pass SIGLIBRT directly to child processes.
+    
+    FreeBSD's librt uses SIGLIBRT as an internal signal to implement
+    SIGEV_THREAD sigevent notifications.  Similar to SIGLWP or SIGCANCEL
+    this signal should be passed through to child processes by default.
+    
+    include/ChangeLog:
+    
+    	* signals.def: Add GDB_SIGNAL_LIBRT.
+    
+    gdb/ChangeLog:
+    
+    	* common/signals.c (gdb_signal_from_host): Handle SIGLIBRT.
+    	(do_gdb_signal_to_host): Likewise.
+    	* infrun.c (_initialize_infrun): Pass GDB_SIGNAL_LIBRT through to
+    	programs.
+    	* proc-events.c (signal_table): Add entry for SIGLIBRT.
