14 // All Maps have a field instance_type containing a InstanceType.
15 // It describes the type of the instances.
16 //
17 // As an example, a JavaScript object is a heap object and its map
18 // instance_type is JS_OBJECT_TYPE.
19 //
20 // The names of the string instance types are intended to systematically
21 // mirror their encoding in the instance_type field of the map. The default
22 // encoding is considered TWO_BYTE. It is not mentioned in the name. ONE_BYTE
23 // encoding is mentioned explicitly in the name. Likewise, the default
24 // representation is considered sequential. It is not mentioned in the
25 // name. The other representations (e.g. CONS, EXTERNAL) are explicitly
26 // mentioned. Finally, the string is either a STRING_TYPE (if it is a normal
27 // string) or a INTERNALIZED_STRING_TYPE (if it is a internalized string).
28 //
29 // NOTE: The following things are some that depend on the string types having
30 // instance_types that are less than those of all other types:
31 // HeapObject::Size, HeapObject::IterateBody, the typeof operator, and
32 // Object::IsString.
33 //
34 // NOTE: Everything following JS_VALUE_TYPE is considered a
35 // JSObject for GC purposes. The first four entries here have typeof
36 // 'object', whereas JS_FUNCTION_TYPE has typeof 'function'.
37 //
38 // NOTE: List had to be split into two, because of conditional item(s) from
39 // INTL namespace. They can't just be appended to the end, because of the
40 // checks we do in tests (expecting JS_FUNCTION_TYPE to be last).
