be more easily re-used. This currently uses some cooked up matching function that I wrote a while ago, but should probably be changed to use regular expressions in the future. add doDebugBreak to control breakpoints on a per SimObject basis SConscript: add match base/stats/events.cc: base/trace.cc: Move the object matching code into a separate file so it can be more easily shared base/trace.hh: the object matching code was wrapped up and moved. adapt. sim/sim_object.cc: add the doDebugBreak flag that can be set on a per-SimObject basis. This will be used in the future to control whether or not debug_break() will actually break for a given object. provide a function interface that can be called from the debugger. sim/sim_object.hh: add the doDebugBreak flag that can be set on a per-SimObject basis. This will be used in the future to control whether or not debug_break() will actually break for a given object. --HG-- extra : convert_revision : 6bf7924de63d41f5ba6b80d579efdf26ba265a8f
