Control the behavior of the C/C++ debugger when debugging with GDB, specifically when using a GDB (DSF) launcher.

Force thread list update on suspend

This checkbox controls whether the CDT debugger will ask gdb for the target program's thread list on each suspend event (breakpoint-hit, step, etc). Normally, this isn't necessary, as GDB sends notifications in realtime when a thread is created or destroyed. However, some lightweight GDB remote stubs won't send these notifications. As such, the CDT debugger doesn't find out about new or destroyed threads unless it polls gdb. Turn on this option if you are debugging such a target (typically an embedded one).
