- improve `JS_DumpString`: use `L` prefix for wide strings
- dump variable kind and flags for locals and closures
- disassemble byte code in DUMP_READ_OBJECT
- pass start_pos to `dump_byte_code` and `dump_single_byte_code`
- write constant pool before function bytecode (bump version to 11)
- update generated code
* Improve REPL directive support
- use . on column 0 as directive prefix
- use `directives` object properties for genericity
- accept non ambiguous directive abbreviations
- reject invalid directive with extra characters
- simplify `handle_directive` and `handle_cmd`
- document ".help" instead of "\h"
- document ".load"
* Improve completion in REPL
- refine `get_context_object` to avoid throwing errors (eg: q.<TAB>)
- do not call `eval` in `get_context_object` to avoid throwing errors
and reduce bloat caused by variable closures.
- support completion of directives
Translate IC opcodes to their non-IC variants before writing them out.
Before this commit they were not byte-swapped properly, breaking the
ability to load serialized bytecode containing ICs on systems with
different endianness. Inline caches are recomputed as needed now.
A pleasing side effect of this change is that serialized bytecode is,
on average, a little smaller because fewer atoms are duplicated now.
* Improve `Date.parse()`
- rewrite `Date.parse()` with separate parsers
- return `NaN` for out of bounds field values as specified
- add `js_tzabbr` and `string_get_tzabbr` to handle timezone abbreviations
- improve `string_get_milliseconds` readability
- 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**
- produce readable output for `Date` objects in repl
- use `JSON.stringify` to output `Date` and `string` values in **repl.js**
- remove `String.prototype.__quote`
- add `minimum_length` macro to specify argument array sizes (C99 except MSVC)
- v8.js: parse all environment variables and output them, update **v8.txt**
