Some notes for using the profiling macros
|
|
|
|
1. Define _PROFILE_ before including "sgx_profile.h" will enable the profiling,
|
|
also need to include sgx_profile.cpp in the compiling process
|
|
2. When use it in multi-threaded application, please don't trigger profiling in multiple threads at the same time.
|
|
The implementation is not thread-safe now, to avoid additional latency introduced by locks
|
|
3. PROFILE_OUTPUT macro should only be used once before application exits
|
|
4. PROFILE_START and PROFILE_END should be paired, otherwise PROFILE_OUTPUT will abort the program when detects the mismatch
|
|
|
|
A simple example to use PROFILE macro
|
|
|
|
#define _PROFILE_
|
|
#include "sgx_profile.h"
|
|
|
|
...
|
|
PROFILE_INIT();
|
|
...
|
|
|
|
PROFILE_START("func1");
|
|
func1();
|
|
PROFILE_END("func1");
|
|
|
|
...
|
|
|
|
PROFILE_START("func2");
|
|
func2();
|
|
PROFILE_END("func2");
|
|
|
|
...
|
|
|
|
PROFILE_OUTPUT("C:\\work\\output.csv");
|
|
...
|
