/**
* @brief JIT Profiling APIs
*
* The JIT Profiling API is used to report information about just-in-time
* generated code that can be used by performance tools. The user inserts
* calls in the code generator to report information before JIT-compiled
* code goes to execution. This information is collected at runtime and used
* by tools like Intel(R) VTune(TM) Amplifier to display performance metrics
* associated with JIT-compiled code.
*
* These APIs can be used to\n
* **Profile trace-based and method-based JIT-compiled
* code**. Some examples of environments that you can profile with this APIs:
* dynamic JIT compilation of JavaScript code traces, OpenCL JIT execution,
* Java/.NET managed execution environments, and custom ISV JIT engines.
*
* @code
* #include <jitprofiling.h>
*
* if (iJIT_IsProfilingActive != iJIT_SAMPLING_ON) {
* return;
* }
*
* iJIT_Method_Load jmethod = {0};
* jmethod.method_id = iJIT_GetNewMethodID();
* jmethod.method_name = "method_name";
* jmethod.class_file_name = "class_name";
* jmethod.source_file_name = "source_file_name";
* jmethod.method_load_address = code_addr;
* jmethod.method_size = code_size;
*
* iJIT_NotifyEvent(iJVM_EVENT_TYPE_METHOD_LOAD_FINISHED, (void*)&jmethod);
* iJIT_NotifyEvent(iJVM_EVENT_TYPE_SHUTDOWN, NULL);
* @endcode
*
* * Expected behaviour:
* * If any iJVM_EVENT_TYPE_METHOD_LOAD_FINISHED event overwrites
* already reported method, then such a method becomes invalid and its
* memory region is treated as unloaded. VTune Amplifier displays the metrics
* collected by the method until it is overwritten.
* * If supplied line number information contains multiple source lines for
* the same assembly instruction (code location), then VTune Amplifier picks up
* the first line number.
* * Dynamically generated code can be associated with a module name.
* Use the iJIT_Method_Load_V2 structure.\n
* Clarification of some cases:\n
* * If you register a function with the same method ID multiple times
* specifying different module names, then the VTune Amplifier picks up
* the module name registered first. If you want to distinguish the same
* function between different JIT engines, supply different method IDs for
* each function. Other symbolic information (for example, source file)
* can be identical.
*
* **Analyze split functions** (multiple joint or disjoint code regions
* belonging to the same function) **including re-JIT**
* with potential overlapping of code regions in time, which is common in
* resource-limited environments.
* @code
* #include <jitprofiling.h>
*
* unsigned int method_id = iJIT_GetNewMethodID();
*
* iJIT_Method_Load a = {0};
* a.method_id = method_id;
* a.method_load_address = acode_addr;
* a.method_size = acode_size;
*
* iJIT_Method_Load b = {0};
* b.method_id = method_id;
* b.method_load_address = baddr_second;
* b.method_size = bsize_second;
*
* iJIT_NotifyEvent(iJVM_EVENT_TYPE_METHOD_LOAD_FINISHED, (void*)&a);
* iJIT_NotifyEvent(iJVM_EVENT_TYPE_METHOD_LOAD_FINISHED, (void*)&b);
* @endcode
*
* * Expected behaviour:
* * If a iJVM_EVENT_TYPE_METHOD_LOAD_FINISHED event overwrites
* already reported method, then such a method becomes invalid and
* its memory region is treated as unloaded.
* * All code regions reported with the same method ID are considered as
* belonging to the same method. Symbolic information (method name,
* source file name) will be taken from the first notification, all
* subsequent notifications with the same method ID will be processed
* only for line number table information. So, the VTune Amplifier will map
* samples to a source line using the line number table from the current
* notification while taking source file name from the very first one.\n
* Clarification of some cases:\n
* * If you register a second code region with a different source file
* name and the same method ID, then this information will be saved and
* will not be considered as an extension of the first code region, but
* VTune Amplifier will use source file of the first code region and map
* performance metrics incorrectly.
* * If you register a second code region with the same source file as
* for the first region and the same method ID, then source file will be
* discarded but VTune Amplifier will map metrics to the source file correctly.
* * If you register a second code region with a null source file and
* the same method ID, then provided line number info will be associated
* with the source file of the first code region.
*
* **Explore inline functions** including multi-level hierarchy of
* nested inlines to see how performance metrics are distributed through them.
*
* @code
* #include <jitprofiling.h>

* * Requirements:
* * Each inline (iJIT_Method_Inline_Load) method should be associated
* with two method IDs: one for itself, one for its immediate parent.
* * Address regions of inline methods of the same parent method cannot
* overlap each other.
* * Execution of the parent method must not be started until it and all
* its inlines are reported.
* * Expected behaviour:
* * In case of nested inlines an order of
* iJVM_EVENT_TYPE_METHOD_INLINE_LOAD_FINISHED events is not important.
* * If any event overwrites either inline method or top parent method,
* then the parent including inlines becomes invalid and its memory
* region is treated as unloaded.
*
* **Life time of allocated data**\n
* The client sends an event notification to the agent with event-specific
* data, which is a structure. The pointers in the structure refers to memory
* allocated by the client, which responsible for releasing it. The pointers are
* used by the iJIT_NotifyEvent method to copy client's data in a trace file
* and they are not used after the iJIT_NotifyEvent method returns.
