/*
|
||||
* Prof
|
||||
* ====
|
||||
*
|
||||
* Self-contained C/C++ profiler library for Linux.
|
||||
*
|
||||
* Prof offers a quick way to measure performance events (CPU clock cycles,
|
||||
* cache misses, branch mispredictions, etc.) of C/C++ code snippets. Prof is
|
||||
* just a wrapper around the `perf_event_open` system call, its main goal is to
|
||||
* be easy to setup and painless to use for targeted optimizations, namely, when
|
||||
* the hot spot has already been identified. In no way Prof is a replacement for
|
||||
* a fully-fledged profiler like perf, gprof, callgrind, etc.
|
||||
*
|
||||
* Please be aware that Prof uses `__attribute__((constructor))` to be as more
|
||||
* straightforward to setup as possible, so it cannot be included more than
|
||||
* once.
|
||||
*
|
||||
* Examples
|
||||
* --------
|
||||
*
|
||||
* ### Minimal
|
||||
*
|
||||
* The following snippet prints the rough number of CPU clock cycles spent in
|
||||
* executing the code between the two Prof calls:
|
||||
*
|
||||
* ```c
|
||||
* #include "prof.h"
|
||||
*
|
||||
* int main()
|
||||
* {
|
||||
* PROF_START();
|
||||
* // slow code goes here...
|
||||
* PROF_STDOUT();
|
||||
* }
|
||||
* ```
|
||||
*
|
||||
* ### Custom options
|
||||
*
|
||||
* The following snippet instead counts both read and write faults of the level
|
||||
* 1 data cache that occur in the userland code between the two Prof calls:
|
||||
*
|
||||
* ```c
|
||||
* #include <stdio.h>
|
||||
*
|
||||
* #define PROF_USER_EVENTS_ONLY
|
||||
* #define PROF_EVENT_LIST \
|
||||
* PROF_EVENT_CACHE(L1D, READ, MISS) \
|
||||
* PROF_EVENT_CACHE(L1D, WRITE, MISS)
|
||||
* #include "prof.h"
|
||||
*
|
||||
* int main()
|
||||
* {
|
||||
* uint64_t faults[2] = { 0 };
|
||||
*
|
||||
* PROF_START();
|
||||
* // slow code goes here...
|
||||
* PROF_DO(faults[index] += counter);
|
||||
*
|
||||
* // fast or uninteresting code goes here...
|
||||
*
|
||||
* PROF_START();
|
||||
* // slow code goes here...
|
||||
* PROF_DO(faults[index] += counter);
|
||||
*
|
||||
* printf("Total L1 faults: R = %lu; W = %lu\n", faults[0], faults[1]);
|
||||
* }
|
||||
* ```
|
||||
*
|
||||
* Installation
|
||||
* ------------
|
||||
*
|
||||
* Just include `prof.h`. Here is a quick way to fetch the latest version:
|
||||
*
|
||||
* wget -q https://raw.githubusercontent.com/cyrus-and/prof/master/prof.h
