• Overview
• Either interpreter or compiler. Not both.
• Superblocks and executors
• Creating executors
• Exits from executors
• Linking executors
• Making progress
• Inter-superblock optimization
• Making "hot" exits fast and "cold" exits small
• The implementation
• Making "hot" exits fast
• Making "cold" exits small
• Minimizing memory use
• Each executor gets a table of exit data
• Fixed number of exit objects
• Exit data
• Representation changes
• Hotness counters
• EXIT_IF and UNLIKELY_EXIT_IF
• Guaranteeing progress
• Guaranteeing progress within an executor
• Exiting to invalid executors
• The mechanics of transferring execution between executors
• JIT compiler
• Interpreter
• Future optimizations
