- The bytecode translator is responsible for converting incoming bytecode instructions into
a high-level intermediate representation. This IR is of a lower level than the bytecode and
breaks complex bytecode operations into several simple instructions to expose more opportunities
to later high-level optimization phases. For example, loading an object field is broken up
into operations that perform a null check of the object reference, load the base address of
the object, compute the address of the field, and load the value at that computed address.
