//
// Here are a few examples of using the value-profiling utility:
//
// _vprof (e);
// at the end of program execution, you'll get a dump of the source location of this probe,
// its min, max, average, the total sum of all instances of e, and the total number of times this probe was called.
//
// _vprof (x > 0);
// shows how many times and what percentage of the cases x was > 0,
// that is the probablitiy that x > 0.
//
// _vprof (n % 2 == 0);
// shows how many times n was an even number
// as well as th probablitiy of n being an even number.
//
// _hprof (n, 4, 1000, 5000, 5001, 10000);
// gives you the histogram of n over the given 4 bucket boundaries:
// # cases < 1000
// # cases >= 1000 and < 5000
// # cases >= 5000 and < 5001
// # cases >= 5001 and < 10000
// # cases >= 10000
//
// _nvprof ("event name", value);
// all instances with the same name are merged
// so, you can call _vprof with the same event name at difference places
//
// _vprof (e, myProbe);
// value profile e and call myProbe (void* vprofID) at the profiling point.
// inside the probe, the client has the predefined variables:
// _VAL, _COUNT, _SUM, _MIN, _MAX, and the general purpose registers
// _IVAR1, ..., IVAR4 general integer registrs
// _I64VAR1, ..., I64VAR4 general integer64 registrs
// _DVAR1, ..., _DVAR4 general double registers
// _GENPTR a generic pointer that can be used by the client
// the number of registers can be changed in vprof.h
//
