Sami Vaarala	de6d2e1f85	Update index page lowmem info	10 years ago
Sami Vaarala	530f6e7ff7	16-bit fields and heap pointer compression work Memory optimization work for very low memory devices (96 to 256kB system RAM). Overall changes are: - 16-bit fields for various internal structures to reduce their size - Heap pointer compression to reduce pointer size to 16 bits When DUK_OPT_LIGHTFUNC_BUILTINS and the new low memory options are enabled, Duktape initial heap memory usage is about 23kB (compared to baseline of about 45kB) on x86. Unless low memory feature options are enabled, there should be no visible changes to Duktape behavior. More detailed changes: - 16-bit changes for duk_heaphdr: pointer compression, refcount - 16-bit changes for duk_hstring: hash, blen, and clen can all be 16 bits, use 0xFFFF as string byte length limit (call sites ensure this limit is never exceeded) - 16-bit changes for duk_hbuffer, use 0xFFFF as buffer length limit - 16-bit fields for hobject size (entry part, array part), drop hash part since it's not usually needed for extremely low memory environments - 16-bit changes for duk_hcompiledfunction - Heap pointer packing for stringtable - Heap pointer packing for 'strs' built-in strings list (saves around 600 to 700 bytes but may not be a good tradeoff because call site size will increase) Other changes: - Heaphdr NULL init fix. The original macros were broken: the double/single linked macro variants were the wrong way around. Now sets through macro to work properly with compressed pointers. - Rename duk_hbuffer CURR_DATA_PTR -> DATA_PTR to reduce macro length (previous name was tediously long) - Rename buffer "usable_size" to "alloc_size" throughout as they have been the same for a while now (they used to differ when buffer had an extra NUL). - Add memory optimization markers to Duktape.env (pointer compression and individual 16-bit field options) - Rename a few internal fields for clarity: duk_hobject 'p' to 'props', heap->st to heap->strtable - Add a safety check for buffer alloc size (should not be triggered but prevents wrapping if call sites don't properly check for sizes) - Other minor cleanups	10 years ago
Sami Vaarala	5e56112176	Second round of lightfunc support improvements * Fix outstanding FIXME issues for lightfunc semantics. * Improve API and Ecmascript testcases to match. * Clarify lightfunc limitations, e.g. finalizer limitations. * Guide and API documentation changes for lightfuncs. * Fix compile warning: duk_str_not_object unused.	10 years ago
