command line:
m5.* <config file> <args> --server.system:bin=true to track function calls in the server
m5.* <config file> <args> --client.system:bin=true to track function calls in the client
base/statistics.cc:
make an adjustment to the way stats are printed for FS_MEASURE
base/statistics.hh:
add a name() virtual function to GenBin. add a debug printf for activate().
add amake MainBin the default bin when FS_MEASURE.
cpu/exec_context.cc:
initialize swCtx to null upon creation of an xc
cpu/exec_context.hh:
add a SWContext pointer to every execution context.
cpu/simple_cpu/simple_cpu.cc:
process calls and returns for FS_MEASURE
cpu/simple_cpu/simple_cpu.hh:
add this so idleCycles will not be accessed before all stats are constructed
kern/tru64/tru64_events.cc:
add a FnEvent that fires whenever a function we're tracking is called. implement the process() virtual function for it.
kern/tru64/tru64_events.hh:
add FnEvent
kern/tru64/tru64_system.cc:
send bin parameter to System constructor. add bin parameter to Tru64System object. initialize all the FnEvent and MainBin members of Tru64system. also, populate the calling map that indicates whether a function call is on the path we're tracking.
kern/tru64/tru64_system.hh:
modify the Tru64System class to support FS_MEASURE
sim/system.cc:
add a bin parameter to System class. initialize a MainBin to hold the stats for nonPath.
sim/system.hh:
add a map of to match bins to function names. add a swCtx map to map pcb addresses to SWContext *s. Add some supporting functions.
