2 * Heap object representation.
3 *
4 * Heap objects are used for Ecmascript objects, arrays, and functions,
5 * but also for internal control like declarative and object environment
6 * records. Compiled functions, native functions, and threads are also
7 * objects but with an extended C struct.
8 *
9 * Objects provide the required Ecmascript semantics and exotic behaviors
10 * especially for property access.
11 *
12 * Properties are stored in three conceptual parts:
13 *
14 * 1. A linear 'entry part' contains ordered key-value-attributes triples
15 * and is the main method of string properties.
16 *
17 * 2. An optional linear 'array part' is used for array objects to store a
18 * (dense) range of [0,N[ array indexed entries with default attributes
19 * (writable, enumerable, configurable). If the array part would become
20 * sparse or non-default attributes are required, the array part is
21 * abandoned and moved to the 'entry part'.
22 *
23 * 3. An optional 'hash part' is used to optimize lookups of the entry
24 * part; it is used only for objects with sufficiently many properties
25 * and can be abandoned without loss of information.
26 *
27 * These three conceptual parts are stored in a single memory allocated area.
28 * This minimizes memory allocation overhead but also means that all three
29 * parts are resized together, and makes property access a bit complicated.

732 * h_size * sizeof(duk_uint32_t) bytes of (opt) hash indexes to entries (e_size),
733 * 0xffffffffUL = unused, 0xfffffffeUL = deleted
734 *
735 * Layout 2 (DUK_USE_HOBJECT_LAYOUT_2):
736 *
737 * e_size * sizeof(duk_propvalue) bytes of entry values (e_next gc reachable)
738 * e_size * sizeof(duk_hstring *) bytes of entry keys (e_next gc reachable)
739 * e_size * sizeof(duk_uint8_t) + pad bytes of entry flags (e_next gc reachable)
740 * a_size * sizeof(duk_tval) bytes of (opt) array values (plain only) (all gc reachable)
741 * h_size * sizeof(duk_uint32_t) bytes of (opt) hash indexes to entries (e_size),
742 * 0xffffffffUL = unused, 0xfffffffeUL = deleted
743 *
744 * Layout 3 (DUK_USE_HOBJECT_LAYOUT_3):
745 *
746 * e_size * sizeof(duk_propvalue) bytes of entry values (e_next gc reachable)
747 * a_size * sizeof(duk_tval) bytes of (opt) array values (plain only) (all gc reachable)
748 * e_size * sizeof(duk_hstring *) bytes of entry keys (e_next gc reachable)
749 * h_size * sizeof(duk_uint32_t) bytes of (opt) hash indexes to entries (e_size),
750 * 0xffffffffUL = unused, 0xfffffffeUL = deleted
751 * e_size * sizeof(duk_uint8_t) bytes of entry flags (e_next gc reachable)
752 *
753 * In layout 1, the 'e_next' count is rounded to 4 or 8 on platforms
754 * requiring 4 or 8 byte alignment. This ensures proper alignment
755 * for the entries, at the cost of memory footprint. However, it's
756 * probably preferable to use another layout on such platforms instead.
757 *
758 * In layout 2, the key and value parts are swapped to avoid padding
759 * the key array on platforms requiring alignment by 8. The flags part
760 * is padded to get alignment for array entries. The 'e_next' count does
761 * not need to be rounded as in layout 1.
762 *
763 * In layout 3, entry values and array values are always aligned properly,
764 * and assuming pointers are at most 8 bytes, so are the entry keys. Hash
765 * indices will be properly aligned (assuming pointers are at least 4 bytes).
766 * Finally, flags don't need additional alignment. This layout provides
767 * compact allocations without padding (even on platforms with alignment
768 * requirements) at the cost of a bit slower lookups.
769 *
770 * Objects with few keys don't have a hash index; keys are looked up linearly,
771 * which is cache efficient because the keys are consecutive. Larger objects
772 * have a hash index part which contains integer indexes to the entries part.
773 *
774 * A single allocation reduces memory allocation overhead but requires more
775 * work when any part needs to be resized. A sliced allocation for entries
776 * makes linear key matching faster on most platforms (more locality) and
777 * skimps on flags size (which would be followed by 3 bytes of padding in
778 * most architectures if entries were placed in a struct).
779 *
780 * 'props' also contains internal properties distinguished with a non-BMP
781 * prefix. Often used properties should be placed early in 'props' whenever
782 * possible to make accessing them as fast a possible.
