Quick, non-optimizing JIT (fullcode)

■

Inline caching, type feedback

NOT: Control Flow Graph (CFG)

Fully-specified evaluation order; e.g. pure operations like integer addition

INSPIRATION: Sea of Nodes

Relax evaluation order for most operations

Effect edges order stateful operations

Relax Sea of Nodes control flow subgraph even further

Disconnected “floating control” islands offer more scheduling freedom

Why? Lowering of language levels, even more code motion
