Vtune profiling support in SGX enclave

Hi, as I know, "SGX Hotspots" is supproted in vtune since 2016.
I noticed that there is a piece of code of function ` __create_enclave` in psw (urts/urts_com.h), so what is the propose of this code below? Is it helpful for vtune profiling in sgx enclave? How can I enable the `isVTuneProfiling` flag?

` if(debug || !(get_enclave_creator()->use_se_hw()))
{
SE_TRACE(SE_TRACE_DEBUG, "Debug enclave. Checking if VTune is profiling or SGX_DBG_OPTIN is set\n");

__itt_init_ittlib(NULL, __itt_group_none);
bool isVTuneProfiling;
if(__itt_get_ittapi_global()->api_initialized && __itt_get_ittapi_global()->lib)
isVTuneProfiling = true;
else
isVTuneProfiling = false;

bool is_SGX_DBG_OPTIN_set = false;
is_SGX_DBG_OPTIN_set = is_SGX_DBG_OPTIN_variable_set();
if (isVTuneProfiling || is_SGX_DBG_OPTIN_set)
{
SE_TRACE(SE_TRACE_DEBUG, "VTune is profiling or SGX_DBG_OPTIN is set\n");

bool thread_updated;
thread_updated = enclave->update_debug_flag(1);

if(thread_updated == false)
{
SE_TRACE(SE_TRACE_DEBUG, "Failed to update debug OPTIN bit\n");
}
else
{
SE_TRACE(SE_TRACE_DEBUG, "Updated debug OPTIN bit\n");
}

if (isVTuneProfiling)
{
uint64_t enclave_start_addr;
uint64_t enclave_end_addr;
const char* enclave_path;
enclave_start_addr = (uint64_t) loader.get_start_addr();
enclave_end_addr = enclave_start_addr + (uint64_t) metadata->enclave_size -1;

SE_TRACE(SE_TRACE_DEBUG, "Invoking VTune's module mapping API __itt_module_load \n");
SE_TRACE(SE_TRACE_DEBUG, "Enclave_start_addr==0x%llx\n", enclave_start_addr);
SE_TRACE(SE_TRACE_DEBUG, "Enclave_end_addr==0x%llx\n", enclave_end_addr);

enclave_path = (const char*)file.name;
SE_TRACE(SE_TRACE_DEBUG, "Enclave_path==%s\n", enclave_path);
__itt_module_load((void*)enclave_start_addr, (void*) enclave_end_addr, enclave_path);
}
}`

Start in psw/urts/urts_com.h at __create_enclave and trace the __itt_init_ittlib, isVTuneProfiling, and __itt_module_load calls. Check how SGX_DBG_OPTIN is detected and how the loader obtains enclave addresses and paths. Done means documenting whether this code enables VTune profiling and the supported way to activate it.
