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");
...
