addArchive - Add an Archive to the execution engine.
This method is only supported by MCJIT. MCJIT will use the archive to resolve external symbols in objects it is loading. If a symbol is found in the Archive the contained object file will be extracted (in memory) and loaded for possible execution.

addObjectFile - Add an ObjectFile to the execution engine.
This method is only supported by MCJIT. MCJIT will immediately load the object into memory and adds its symbols to the list used to resolve external symbols while preparing other objects for execution.
Objects added using this function will not be made executable until needed by another object.
MCJIT will take ownership of the ObjectFile.

finalizeObject - ensure the module is fully processed and is usable.
It is the user-level function for completing the process of making the object usable for execution. It should be called after sections within an object have been relocated using mapSectionAddress. When this method is called the MCJIT execution engine will reapply relocations for a loaded object. This method has no effect for the interpeter.

getPointerToFunction - The different EE's represent function bodies in different ways.
They should each implement this to say what a function pointer should look like. When F is destroyed, the ExecutionEngine will remove its global mapping and free any machine code. Be sure no threads are running inside F when that happens.
This function is deprecated for the MCJIT execution engine. Use getFunctionAddress instead.

getPointerToNamedFunction - This method returns the address of the specified function by using the dlsym function call.
As such it is only useful for resolving library symbols, not code generated symbols.
If AbortOnFailure is false and no function with the given name is found, this function silently returns a null pointer. Otherwise, it prints a message to stderr and aborts.
This function is deprecated for the MCJIT execution engine.

mapSectionAddress - map a section to its target address space value.
Map the address of a JIT section as returned from the memory manager to the address in the target process as the running code will see it. This is the address which will be used for relocation resolution.

runFunction - Execute the specified function with the specified arguments, and return the result.
For MCJIT execution engines, clients are encouraged to use the "GetFunctionAddress" method (rather than runFunction) and cast the returned uint64_t to the desired function pointer type. However, for backwards compatibility MCJIT's implementation can execute 'main-like' function (i.e. those returning void or int, and taking either no arguments or (int, char*[])).

setProcessAllSections (MCJIT Only): By default, only sections that are "required for execution" are passed to the RTDyldMemoryManager, and other sections are discarded.
Passing 'true' to this method will cause RuntimeDyld to pass all sections to its RTDyldMemoryManager regardless of whether they are "required to execute" in the usual sense.
Rationale: Some MCJIT clients want to be able to inspect metadata sections (e.g. Dwarf, Stack-maps) to enable functionality or analyze performance. Passing these sections to the memory manager allows the client to make policy about the relevant sections, rather than having MCJIT do it.
