63195 * runtime, so the RETURN must still be emitted. (Duktape
63196 * 0.10.0 avoided this and simulated a RETURN if a tail call
63197 * couldn't be used at runtime; but this didn't work
63198 * correctly with a thread yield/resume, see
63199 * test-bug-tailcall-thread-yield-resume.js for discussion.)
63200 *
63201 * In addition to the last opcode being CALL, we also need to
63202 * be sure that 'rc_val' is the result register of the CALL(I).
63203 * For instance, for the expression 'return 0, (function ()
63204 * { return 1; }), 2' the last opcode emitted is CALL (no
63205 * bytecode is emitted for '2') but 'rc_val' indicates
63206 * constant '2'. Similarly if '2' is replaced by a register
63207 * bound variable, no opcodes are emitted but tail call would
63208 * be incorrect.
63209 *
63210 * This is tricky and easy to get wrong. It would be best to
63211 * track enough expression metadata to check that 'rc_val' came
63212 * from that last CALL instruction. We don't have that metadata
63213 * now, so we check that 'rc_val' is a temporary register result
63214 * (not a constant or a register bound variable). There should
63215 * be no way currently for 'rc_val' to be a temporary for an
63216 * expression following the CALL instruction without emitting
63217 * some opcodes following the CALL. This proxy check is used
63218 * below.
63219 *
63220 * See: test-bug-comma-expr-gh131.js.
63221 *
63222 * The non-standard 'caller' property disables tail calls
63223 * because they pose some special cases which haven't been
63224 * fixed yet.

26165 * If e.g. UNIX APIs are used, they'll have portability issues with
26166 * very small and very large years.
26167 *
26168 * Current approach:
26169 *
26170 * - Stay within portable UNIX limits by using equivalent year mapping.
26171 * Avoid year 1970 and 2038 as some conversions start to fail, at
26172 * least on some platforms. Avoiding 1970 means that there are
26173 * currently DST discrepancies for 1970.
26174 *
26175 * - Create a UTC and local time breakdowns from 't'. Then create
26176 * a time_t using gmtime() and localtime() and compute the time
26177 * difference between the two.
26178 *
26179 * Equivalent year mapping (E5 Section 15.9.1.8):
26180 *
26181 * If the host environment provides functionality for determining
26182 * daylight saving time, the implementation of ECMAScript is free
26183 * to map the year in question to an equivalent year (same
26184 * leap-year-ness and same starting week day for the year) for which
26185 * the host environment provides daylight saving time information.
26186 * The only restriction is that all equivalent years should produce
26187 * the same result.
26188 *
26189 * This approach is quite reasonable but not entirely correct, e.g.
26190 * the specification also states (E5 Section 15.9.1.8):
26191 *
26192 * The implementation of ECMAScript should not try to determine
26193 * whether the exact time was subject to daylight saving time, but
26194 * just whether daylight saving time would have been in effect if
26195 * the _current daylight saving time algorithm_ had been used at the
26196 * time. This avoids complications such as taking into account the
26197 * years that the locale observed daylight saving time year round.
26198 *
26199 * Since we rely on the platform APIs for conversions between local
26200 * time and UTC, we can't guarantee the above. Rather, if the platform
26201 * has historical DST rules they will be applied. This seems to be the
26202 * general preferred direction in Ecmascript standardization (or at least
26203 * implementations) anyway, and even the equivalent year mapping should
26204 * be disabled if the platform is known to handle DST properly for the
26205 * full Ecmascript range.
26206 *
26207 * The following has useful discussion and links:

23164 * - Source and target separate buffers or non-overlapping.
23165 *
23166 * - Source and target have a compatible type so that a plain byte copy
23167 * is possible. Note that while e.g. uint8 and int8 are compatible
23168 * (coercion one way or another doesn't change the byte representation),
23169 * e.g. int8 and uint8clamped are NOT compatible when writing int8
23170 * values into uint8clamped typedarray (-1 would clamp to 0 for instance).

73752 * "/" followed by something in regexp mode. See E5 Section 7.8.5.
73753 *
73754 * RegExp parsing is a bit complex. First, the regexp body is delimited
73755 * by forward slashes, but the body may also contain forward slashes as
73756 * part of an escape sequence or inside a character class (delimited by
73757 * square brackets). A mini state machine is used to implement these.
73758 *
73759 * Further, an early (parse time) error must be thrown if the regexp
73760 * would cause a run-time error when used in the expression new RegExp(...).
73761 * Parsing here simply extracts the (candidate) regexp, and also accepts
73762 * invalid regular expressions (which are delimited properly). The caller
73763 * (compiler) must perform final validation and regexp compilation.
73764 *
73765 * RegExp first char may not be '/' (single line comment) or '*' (multi-
73766 * line comment). These have already been checked above, so there is no
73767 * need below for special handling of the first regexp character as in
73768 * the E5 productions.
73769 *
73770 * About unicode escapes within regexp literals:
73771 *
73772 * E5 Section 7.8.5 grammar does NOT accept \uHHHH escapes.
73773 * However, Section 6 states that regexps accept the escapes,
73774 * see paragraph starting with "In string literals...".
73775 * The regexp grammar, which sees the decoded regexp literal
73776 * (after lexical parsing) DOES have a \uHHHH unicode escape.
73777 * So, for instance:
73778 *
73779 * /\u1234/
73780 *
73781 * should first be parsed by the lexical grammar as:
73782 *
73783 * '\' 'u' RegularExpressionBackslashSequence
73784 * '1' RegularExpressionNonTerminator
73785 * '2' RegularExpressionNonTerminator
73786 * '3' RegularExpressionNonTerminator
73787 * '4' RegularExpressionNonTerminator
73788 *
73789 * and the escape itself is then parsed by the regexp engine.
73790 * This is the current implementation.
73791 *
73792 * Minor spec inconsistency:
73793 *
73794 * E5 Section 7.8.5 RegularExpressionBackslashSequence is:
73795 *
73796 * \ RegularExpressionNonTerminator
73797 *
73798 * while Section A.1 RegularExpressionBackslashSequence is:
73799 *
73800 * \ NonTerminator
73801 *
73802 * The latter is not normative and a typo.

12568 * There are two [[Construct]] operations in the specification:
12569 *
12570 * - E5 Section 13.2.2: for Function objects
12571 * - E5 Section 15.3.4.5.2: for "bound" Function objects
12572 *
12573 * The chain of bound functions is resolved in Section 15.3.4.5.2,
12574 * with arguments "piling up" until the [[Construct]] internal
12575 * method is called on the final, actual Function object. Note
12576 * that the "prototype" property is looked up *only* from the
12577 * final object, *before* calling the constructor.
12578 *
12579 * Currently we follow the bound function chain here to get the
12580 * "prototype" property value from the final, non-bound function.
12581 * However, we let duk_handle_call() handle the argument "piling"
12582 * when the constructor is called. The bound function chain is
12583 * thus now processed twice.
12584 *
12585 * When constructing new Array instances, an unnecessary object is
12586 * created and discarded now: the standard [[Construct]] creates an
12587 * object, and calls the Array constructor. The Array constructor
12588 * returns an Array instance, which is used as the result value for
12589 * the "new" operation; the object created before the Array constructor
12590 * call is discarded.
12591 *
12592 * This would be easy to fix, e.g. by knowing that the Array constructor
12593 * will always create a replacement object and skip creating the fallback
12594 * object in that case.
12595 *
12596 * Note: functions called via "new" need to know they are called as a
12597 * constructor. For instance, built-in constructors behave differently
12598 * depending on how they are called.

10554 * duk_unicode_is_identifier_start().
10555 *
10556 * To match non-ASCII characters (codepoints >= 0x80), a very slow
10557 * linear range-by-range scan is used. The codepoint is first compared
10558 * to the IdentifierStart ranges, and if it doesn't match, then to a
10559 * set consisting of code points in IdentifierPart but not in
10560 * IdentifierStart. This is done to keep the unicode range data small,
10561 * at the expense of speed.
10562 *
10563 * The ASCII fast path consists of:
10564 *
10565 * 0x0030 ... 0x0039 ['0' ... '9', UnicodeDigit]
10566 * 0x0041 ... 0x005a ['A' ... 'Z', IdentifierStart]

10568 * 0x0024 ['$', IdentifierStart]
10569 * 0x005f ['_', IdentifierStart and
10570 * UnicodeConnectorPunctuation]
10571 *
10572 * UnicodeCombiningMark has no code points <= 0x7f.
10573 *
10574 * The matching code reuses the "identifier start" tables, and then
10575 * consults a separate range set for characters in "identifier part"
10576 * but not in "identifier start". These can be extracted with the
10577 * "src/extract_chars.py" script.
