The following page has been changed by Mikhail Fursov: http://wiki.apache.org/harmony/Jitrino_OPT/translator ------------------------------------------------------------------------------ + ''' 'translator' ''' - translates Java language bytecode into High-level Intermediate representation (aka HIR) + [[BR]][[BR]] The bytecode translator is responsible for converting incoming bytecode instructions into a [:../opcodes: 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.
