Module feedback 

Feedback vectors for inline cache (IC) type profiling.

Each function gets an optional FeedbackVector that records observed types at IC-eligible sites (calls, property accesses, arithmetic, method dispatch). The JIT compiler reads this feedback to generate speculative optimizations.

Structs

ArithmeticFeedback

Arithmetic feedback: which operand type pairs observed.

ArithmeticTypePair

CallFeedback

Call site feedback: which function targets have been called.

CallTarget

FeedbackVector

Per-function feedback vector: maps bytecode offsets to IC slots.

MethodCacheEntry

MethodFeedback

Method dispatch feedback: which receiver kinds and method handlers observed.

PropertyCacheEntry

PropertyFeedback

Property access feedback: which schemas and field indices observed.

Enums

FeedbackSlot

A feedback slot records type observations at a single IC site.

ICState

IC state machine: tracks how polymorphic a site has become.

Constants

RECEIVER_HASHMAP

RECEIVER_TYPED_OBJECT

Receiver kind discriminator for property feedback. Tells the JIT whether to emit a TypedObject schema guard or a HashMap shape guard.
