Overall gist of this is to 'dynamicize' the tracking of functions so you can choose them at the .ini stage rather than at compile time.
to do it:
in .ini file set binned_fns=foo null bar foo
what this says is, track foo when it is called by null (i.e. anything). bin bar only when it is called by foo.
essentially, if you have a path of functions to track, the 0th, 2nd, 4th fn listed are the fns to track, and the 1st, 3rd, 5th are their respective callers.
base/statistics.hh:
turn it back to FS_MEASURE since we already have a build in place
kern/tru64/tru64_events.cc:
remove FS_MEASURE #defs. add more DPRINTF's. manage an anomaly that happens when tracking idle_thread.
kern/tru64/tru64_events.hh:
remove FS_MEASURE #defs
kern/tru64/tru64_system.cc:
make DumpState print all the time, but only with DPRINTF. add a new parameter to tru64System a vector<string> binned_fns, to read in from .ini file. now all this binning stuff is dynamically generated.
kern/tru64/tru64_system.hh:
remove all static binning stuff, add support for dynamic
sim/system.cc:
change nonPath bin name to Kernel, remove FS_MEASURE
sim/system.hh:
change nonPath to Kernel
