- accept many more alternative date/time formats
- add test cases in tests/test_builtin.js
- match month and timezone names case insensitively
- accept AM and PM markers
- recognize US timezone names
- skip parenthesized stuff
- fix almost all v8 test cases
- fix the conversions for integers and exact fractions
- approximate approach for other cases.
- bypass floating point conversions for JS_TAG_INT values
- avoid divisions for base 10 integer conversions
- rewrite Date.parse() with separate parsers
- return `NaN` for out of bounds field values as specified
- accept up to 9 decimals for millisecond fraction but truncate at 3
- accept many more alternative date/time formats
- add test cases in tests/test_builtin.js
- use `double` arithmetic where necessary to match the spec
- use `volatile` to ensure correct order of evaluation
and prevent FMA code generation
- reject some border cases.
- avoid undefined behavior in `double` -> `int64_t` conversions
- improved tests/test_builtin.js `assert` function to compare
values more reliably.
- added some tests in `test_date()`
- disable some of these tests on win32 and cygwin targets
If you want to extend a built-in class you need it's class ID and there
is no robust way to get that without this accessor.
* add JS_INVALID_CLASS_ID constant for invalid class ID.

- add inline function to test and convert surrogates
is_surrogate(c), is_hi_surrogate(c), is_lo_surrogate(c),
get_hi_surrogate(c), get_lo_surrogate(c), from_surrogate(hi, lo)
- use names for BC header offsets and lengths in libregexp.c
- remove strict aliasing violations in `lre_exec_backtrack()`
- pass all context variables to XXX_CHAR macros in `lre_exec_backtrack()`
Big endian serialization was broken because:
- it partially relied on `WORDS_ENDIAN` (unconditionally undef'd in cutils.h)
- endianness was not handled at all in the bc reader.
Modifications:
- remove `WORDS_ENDIAN`
- use `bc_put_u32()` / `bc_put_u64()` in `JS_WriteBigInt()`
- use `bc_get_u32()` / `bc_get_u64()` in `JS_ReadBigInt()`
- handle host endianness in `bc_get_u16()`, `bc_get_u32()`, `bc_get_u64()` and
`JS_ReadFunctionBytecode()`
- handle optional littleEndian argument as specified in
`js_dataview_getValue()` and `js_dataview_setValue()`
- Use uint32_t arithmetics and Standard conformant conversion to
avoid UB in js_math_imul.
- add builtin tests
- use specific object directories for SAN targets
ssize_t is not always available and the cast it was used in wasn't
necessary in the first place, the value already has the right type.
Note that the field malloc_limit is an int64_t in JSMemoryUsage whereas it
is a size_t in JSMallocState.
- add more cases of in place string concatenation
this temporary hack improves the microbench timing by 30% but
has little impact on the test262 timings.
- remove temporary fix for MemorySanitizer:
setting p->u.array.count to 0 silenced a warning in JS_GetPropertyValue on a
hacky test agains the length of fast_array object.
This hack was removed by commit c3635861f6.
- force evaluation order in `set_date_fields`
- fix evaluation error in test262/test/built-ins/Date/UTC/fp-evaluation-order.js:19:
unexpected error: Test262Error: precision in MakeDate Expected SameValue(«34448384», «34447360») to be true
MemorySanitizer complained about uninitialized reads in
the indexed property code path in JS_GetPropertyValue()
with JS_CLASS_MAPPED_ARGUMENTS objects.
