Create a RTDyldObjectLinkingLayer instance using MCJIT-memory-manager-like callbacks.
This is intended to simplify transitions for existing MCJIT clients. The callbacks used are similar (but not identical) to the callbacks for LLVMCreateSimpleMCJITMemoryManager: Unlike MCJIT, RTDyldObjectLinkingLayer will create a new memory manager for each object linked by calling the given CreateContext callback. This allows for code removal by destroying each allocator individually. Every allocator will be destroyed (if it has not been already) at RTDyldObjectLinkingLayer destruction time, and the NotifyTerminating callback will be called to indicate that no further allocation contexts will be created.
To implement MCJIT-like behavior clients can implement CreateContext, NotifyTerminating, and Destroy as:
void *CreateContext(void *CtxCtx) { return CtxCtx; } void NotifyTerminating(void *CtxCtx) { MyOriginalDestroy(CtxCtx); } void Destroy(void *Ctx) { }
This scheme simply reuses the CreateContextCtx pointer as the one-and-only allocation context.
