Calling Conventions

The native calling convention is designed for fast non-generic calls. It usually uses a specialized signature.

• LLVM ghosts (zero-length types) are omitted.
• LLVM scalars and vectors are passed by value.

An argument or return values that is a homogeneous tuple is sometimes represented as an LLVM vector instead of an LLVM array.

• - Julia representation of function that is being applied
• args - pointer to array of pointers to boxes

The return value is a pointer to a box.

Tuples are always represented as C arrays.
