Detailed Description

JITEventListener - Abstract interface for use by the JIT to notify clients about significant events during compilation.

For example, to notify profilers and debuggers that need to know where functions have been emitted.

The default implementation of each method does nothing.

◆ notifyObjectLoaded()

virtual void llvm::JITEventListener::notifyObjectLoaded ( ObjectKey  K,
const object::ObjectFile Obj,
const RuntimeDyld::LoadedObjectInfo L 
)
inlinevirtual

notifyObjectLoaded - Called after an object has had its sections allocated and addresses assigned to all symbols.

Note: Section memory will not have been relocated yet. notifyFunctionLoaded will not be called for individual functions in the object.

ELF-specific information The ObjectImage contains the generated object image with section headers updated to reflect the address at which sections were loaded and with relocations performed in-place on debug sections.
