Vocabulary
compiler.cfg.instructions

Class description
Instruction that unboxes a pointer in a register so that it can be fed to a C FFI function. For example, if 'src' points to a byte-array, then in 'dst' will be put a pointer to the first byte of that byte array.

dst	Destination register.
src	Source register.
