◆ AddProfilerFunc

Initial value:

ReOptimizeLayer &Parent, ReOptMaterializationUnitID MUID,

ReOptimizeLayer(ExecutionSession &ES, DataLayout &DL, IRLayer &BaseLayer, RedirectableSymbolManager &RM)

uint64_t ReOptMaterializationUnitID

An LLVM Module together with a shared ThreadSafeContext.

unique_function is a type-erasing functor similar to std::function.

AddProfilerFunc will be called when ReOptimizeLayer emits the first version of a materialization unit in order to inject profiling code and reoptimization request code.

◆ ReOptimizeFunc

Initial value:

ReOptimizeLayer &Parent, ReOptMaterializationUnitID MUID,

IntrusiveRefCntPtr< ResourceTracker > ResourceTrackerSP

ReOptimizeFunc will be called when ReOptimizeLayer reoptimization of a materialization unit was requested in order to reoptimize the IR module based on profile data.

OldRT is the ResourceTracker that tracks the old function definitions. The OldRT must be kept alive until it can be guaranteed that every invocation of the old function definitions has been terminated.

◆ reigsterRuntimeFunctions()

Error ReOptimizeLayer::reigsterRuntimeFunctions ( JITDylib & PlatformJD )

Registers reoptimize runtime dispatch handlers to given PlatformJD.

The reoptimization request will not be handled if dispatch handler is not registered by using this function.

◆ reoptimizeIfCallFrequent()

Basic AddProfilerFunc that reoptimizes the function when the call count exceeds CallCountThreshold.
