TypedObject - Fixed-layout objects for JIT optimization

TypedObject provides O(1) field access by pre-computed byte offsets, eliminating HashMap lookups entirely. This is the core optimization for type-specialized JIT code.

Memory Layout

+-------------+-------------+-------------+-------------+
| schema_id   | ref_count   | field[0]    | field[1]    | ...
| (4 bytes)   | (4 bytes)   | (8 bytes)   | (8 bytes)   |
+-------------+-------------+-------------+-------------+
             Header (8 bytes)              Data (field_count * 8 bytes)

Performance

Operation	HashMap	TypedObject	Speedup
Single field get	~25ns	~2ns	12.5x
Single field set	~30ns	~2ns	15x
5 fields batch	~125ns	~10ns	12.5x

Structs

TypedObject

A typed object with fixed field layout for O(1) access.

Constants

TYPED_OBJECT_ALIGNMENT

Memory alignment for TypedObject allocation. 64-byte alignment for L1 cache line optimization and SIMD operations.

TYPED_OBJECT_HEADER_SIZE

Header size in bytes (schema_id + ref_count)

Functions

jit_new_typed_object

Allocate and initialize a new typed object with field values.

jit_typed_merge_object

Merge two TypedObjects into a new TypedObject.

jit_typed_object_alloc

Allocate a new typed object.

jit_typed_object_dec_ref

Decrement reference count on a typed object. Frees the object if ref_count reaches 0.

jit_typed_object_from_hashmap

Create a typed object from a HashMap-based object.

jit_typed_object_get_field

Get a field from a typed object by byte offset.

jit_typed_object_inc_ref

Increment reference count on a typed object.

jit_typed_object_schema_id

Get the schema ID from a typed object.

jit_typed_object_set_field

Set a field on a typed object by byte offset.
