	)

Create an MCJIT execution engine for a module, with the given options.

It is the responsibility of the caller to ensure that all fields in Options up to the given SizeOfOptions are initialized. It is correct to pass a smaller value of SizeOfOptions that omits some fields. The canonical way of using this is:

LLVMMCJITCompilerOptions options; LLVMInitializeMCJITCompilerOptions(&options, sizeof(options)); ... fill in those options you care about LLVMCreateMCJITCompilerForModule(&jit, mod, &options, sizeof(options), &error);

Note that this is also correct, though possibly suboptimal:

LLVMCreateMCJITCompilerForModule(&jit, mod, 0, 0, &error);

		LLVMMemoryManagerAllocateCodeSectionCallback	AllocateCodeSection,
		LLVMMemoryManagerAllocateDataSectionCallback	AllocateDataSection,
		LLVMMemoryManagerFinalizeMemoryCallback	FinalizeMemory,
		LLVMMemoryManagerDestroyCallback	Destroy
	)

Create a simple custom MCJIT memory manager.

This memory manager can intercept allocations in a module-oblivious way. This will return NULL if any of the passed functions are NULL.

Parameters

Opaque	An opaque client object to pass back to the callbacks.
AllocateCodeSection	Allocate a block of memory for executable code.
AllocateDataSection	Allocate a block of memory for data.
FinalizeMemory	Set page permissions and flush cache. Return 0 on success, 1 on error.
