41 // sent through the various VS code DAP set*Breakpoint packets, and these
42 // breakpoints will be labeled with this name so if breakpoint update events
43 // come in for breakpoints that the IDE doesn't know about, like if a
44 // breakpoint is set manually using the debugger console, we won't report any
45 // updates on them and confused the IDE. This function gets called by all of
46 // the breakpoint classes after they set breakpoints to mark a breakpoint as
47 // a UI breakpoint. We can later check a lldb::SBBreakpoint object that comes
48 // in via LLDB breakpoint changed events and check the breakpoint by calling
49 // "bool lldb::SBBreakpoint::MatchesName(const char *)" to check if a
50 // breakpoint in one of the UI breakpoints that we should report changes for.
