- 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
- ensure handler behavior does not depend on n argument
- load and save reference file in node.js
- add -s filename option to name the output reference file
- add targets in Makefile for tests and bencharks using node.js
- fix incorrect timings when not using high resolution timer
- use performance timer in node.js
- output performance factor instead of percentage
- use smaller threshold by default
- add benchmarks for:
date_parse(), prop_update(), prop_clone(), array_slice()
global_func_call(),
- 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()`
- add -t to show timings
- add -C to select compact progress meter
- default to compact progress meter if not attached to console
- set agent stack size to 2MB
- compute module filename relative to current path
- ignore `testdir` for -d and -f options
- return non zero status on errors changes
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()`
- split test_bigfloat.js from test_bignum.js
- make test_date() compatible with node
- document Date constructor string argument format:
should add test cases for invalid strings
- test_argument_scope(): only test this syntax error in strict mode:
`var f = function(a = eval("var arguments")) {};`
- 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.
