Method Summary

Modifier and TypeMethod and Description
public default void
callback(long
a pointer to the memory used for the function's return value.

If the function is declared as returning void, then this value is garbage and should not be used.

Otherwise, the callback must fill the object to which this points, following the same special promotion behavior as LibFFI#ffi_call. That is, in most cases, ret points to an object of exactly the size of the type specified when CIF was constructed. However, integral types narrower than the system register size are widened. In these cases your program may assume that ret points to an ffi_arg object.

a vector of pointers to memory holding the arguments to the function

public long invoke(long Ctx, long ES, long Triple)

A function for constructing an ObjectLinkingLayer instance to be used by an LLJIT instance.

Clients can call OrcLLJITBuilderSetObjectLinkingLayerCreator to set the creator function to use when constructing an LLJIT instance. This can be used to override the default linking layer implementation that would otherwise be chosen by LLJITBuilder.

Object linking layers returned by this function will become owned by the LLJIT instance. The client is not responsible for managing their lifetimes after the function returns.
