15 Move creation of 'this' object from caller to callee in construction.
16
17 Presently the caller of a constructor is responsible for providing a this
18 object. Instead, move the object creation into a new op_create_this opcode,
19 planted in the head of the contructor bytecode for a function. Since the
20 prototype for the object is provided by performing a get_by_id on the callee,
21 also add a new get_callee opcode (this is used to get the callee JSFunction
22 into a register so that a normal get_by_id can be used).
23
24 Currently the caller is also responsible for detecting when op_construct is
25 performed on a JSFunction representing a host function, in which case an
26 exception is thrown – and this check currently takes place when constructing
27 the this object. Instead, mirroring the recent changes for non-host functions,
28 add a parallel code-path for native constructors to follow, with a thunk for
29 invoking native constructors provided by JITStubs, and a constructor-specific
30 NativeFunction on NativeExecutable. Provide an implementation of a host
31 constructor which will throw an exception.

247 All callable objects should have a global object reference
248 https://bugs.webkit.org/show_bug.cgi?id=39495
249
250 All objects that may ever return a value other CallTypeNone
251 or ConstructTypeNone now get a global object in their constructor
252 and store that in their first anonymous slot. We add a new type
253 JSObjectWithGlobalObject to allow us to share this logic as much
254 as possible, however some objects have specific inheritance
255 requirements so we can't just use it universally.
256
257 To enforce this requirement JSValue::getCallData and getConstructData
258 make use of a new "isValidCallee" function to assert that any object
259 that returns a value other than CallType/ConstructTypeNone has a
260 global object in anonymous slot 0.
261
262 In order to ensure that static function slots are converted into
263 function objects with the correct global object, all prototype objects
264 and other classes with static function slots also gain a global object
265 reference. Happily this fixes the long standing issue where host
266 function objects get a prototype from the lexical global object of the
267 first function that calls them, instead of the global object that they
268 are defined on.

615 Bug 39408 - Unify JIT/interpreter return behaviour.
616
617 Presently the JIT and the interpreter have differing implementations in how
618 they handle storing the result of a function call back to the register file.
619 In both cases the op_call ( / _eval / _varargs / op_construct) opcode has an
620 operand indicating the VM register in which the result should be stored.
621 The JIT plants code after the call to store the result, so the value will be
622 stored as soon as the callee has returned. In the interpreter the call
623 passes the return value register id into the callee via the callee callframe,
624 and the callee is responsible for writing the result back into its callers
625 register file after it has restored the parents callframe pointer, but before
626 returning.
627
628 Instead, move the task of writing the call result to the register file into a
629 new opcode (op_call_put_result), and after returning the callee should leave
630 the return value in a canonical location. In the case of the interpreter,
631 this canonical location is a local variable in privateExecute
632 (functionReturnValue), in the case of the JIT this is the normal return value
633 registers (regT0, or regT1:regT0 in JSVALUE32_64). op_call_put_result stores
634 the result from the canonical location to the registerfile.
635
636 In addition to unifying JIT & interpreter behaviour this change allows us to
637 remove a slot from the callframe, omit the write of the result where the
638 return value from the call is not used, and provides a 2% speedup on sunspider
639 in the interpreter.

1099 (JSC::Interpreter::privateExecute):
1100 (JSC::Interpreter::retrieveArguments): Opcodes accessing 'arguments' now
1101 take operands specifying registers, just like all other opcodes.
1102 JSActivation::copyRegisters is no longer responsible for tearing off the
1103 arguments object; instead, the VM is responsible for both.
1104
1105 Also, a behavior change: Each access to f.arguments creates a new object,
1106 unless f itself uses 'arguments'. This matches Chrome, and is necessary
1107 for the optimization. f.arguments is a nonstandard, deprecated feature,
1108 so high fidelity to a given implementation is not necessarily a goal.
1109 Also, as illustrated by the new test case, the identity of f.arguments
1110 has been broken since 2008, except in the case where f itself accesses
1111 f.arguments -- but nobody seemed to notice. So, hopefully this change won't
1112 break the web.

1155 things, too -- like eval code generation.

1223 Bug 39252 - Move host/native JSFunction's NativeFunction onto NativeExecutable.
1224
1225 Currently host functions reuse JSFunction's ScopeChain as storage for their
1226 NativeFunction (the C function pointer to the host function implementation).
1227 Instead, move this onto NativeExecutable. This will allow host functions to
1228 have a scopechain (which will be implemented as a separate patch).

1772 In r59162 a change was made to WebCore's FeatureDefines.xcconfig that enabled FILE_READER and FILE_WRITER.
1773 The author and reviewer of that patch ignored the carefully-worded warning at the top of that file asking
1774 that changes to the file be kept in sync across JavaScriptCore, WebCore and WebKit, as well as being kept
1775 in sync with build-webkit. This led to WebCore and WebKit having different views of Document's vtable
1776 and results in crashes in Safari shortly after launch when virtual function calls resulted in the wrong
1777 function in WebCore being called.
1778
1779 We fix this by bringing the FeatureDefines.xcconfig files in to sync. Based on the ChangeLog message and
1780 other changes in r59162 it appears that enabling FILE_WRITER was unintentional so that particular change
1781 has been reverted.

2041 Fixed version of: "Optimized o[s] where o is a cell and s is a string"
2042 https://bugs.webkit.org/show_bug.cgi?id=38815
2043
2044 Fixed the previous patch for this from Geoff Garen.
2045
2046 The two problems were a missing exception check and a PropertySlot
2047 initialized improperly, leading to crashes and failures in the case
2048 of getters accessed with bracket syntax.
2049
2050 Previous patch:
2051
2052 Optimized o[s] where o is a cell and s is a string, removing some old
2053 code that wasn't really tuned for the JIT.

2055 SunSpider says 0.8% faster.

2207 [WTFURL] Add a buffer for managing the output of the canonicalizer
2208 https://bugs.webkit.org/show_bug.cgi?id=38671
2209
2210 The canonicalizer produces a stream of canonicalized characters, which
2211 we will store in a URLBuffer. URLBuffer is quite similar to Vector,
2212 but serves as an abstraction to isolate us from the underlying
2213 character storage. In the case of WebKit, we'll probably implement a
2214 subclass of URLBuffer with Vector. In Chromium, the backing store is a
2215 std::string, which avoids an unnecessary memcpy that would be caused by
2216 using Vector instead.

2409 [WTFURL] Add core URL parser
2410 https://bugs.webkit.org/show_bug.cgi?id=38572
2411
2412 This patch adds the core of the URL parser. The URL parser uses a
2413 templated notion of a code unit to support different string types.
2414 Later we'll add some non-templated APIs with concrete types that
2415 clients can use more conveniently.
2416
2417 The URLParser has a couple calls to ASSERT(), which I've commented out
2418 for now. I'm not 100% sure how to handle the dependency issues there
2419 yet, so I've punted on the issue for now.
2420
2421 Also, there are a number of methods that are declared public in this
2422 patch that are only used by the canonicalizer. My plan is to make
2423 those private or protected and make the canonicalizer a friend of the
2424 parser. The details will be in a later patch.

2507 Math.sin is frequently called with the same operand, caching the result should

2510 where NaN maps to NaN.

2568 Add logic to the jit to identify comparisons to single character string literals
2569 and then just perform the comparison inline, rather than ignoring the evidence
2570 and attempting to perform an integer comparison.

2668 Bug 38604 - workers-gc2 crashing on Qt
2669
2670 This appears to be due to a couple of issues.
2671 (1) When the atomic string table is deleted it does not clear the 'inTable' bit
2672 on AtomicStrings - it implicitly assumes that all AtomicStrings have already
2673 been deleted at this point (otherwise they will crash in their destructor when
2674 they try to remove themselves from the atomic string table).
2675 (2) We don't fix the ordering in which WTF::WTFThreadData and
2676 WebCore::ThreadGlobalData are destructed.
2677
2678 We should make sure that ThreadGlobalData is cleaned up before worker threads
2679 terminate and WTF::WTFThreadData is destroyed, and we should clear the inTable
2680 bit of members on atomic string table destruction.
2681
2682 WTF changes (fix issue 1, above) - ensure inTable property is cleared when the
2683 atomic string table is destroyed (also, rename InTable to IsAtomic, to make it
2684 clear which table we are refering to!)

3410 Need to support more efficient dispatch of lightweight builtins
3411 https://bugs.webkit.org/show_bug.cgi?id=38155
3412
3413 The problem with calling lightweight builtins is that marshalling
3414 the call from the nitro calling convention to the system calling
3415 convention is very expensive relative to the cost of the actually
3416 evaluating the function. To work around this problem this patch
3417 adds the ability to define a custom thunk for a builtin.
3418
3419 This allows us to use high performance custom implementations of
3420 the common and sensible versions of simple builtins. This patch
3421 includes a simple (use of which is currently hardcoded) thunk for
3422 charCodeAt.
3423
3424 This adds a JSInterfaceJIT subclass called SpecializedThunkJIT
3425 that has helper functions to remove (or at least reduce) the need
3426 to have separate thunk implementations for each JSValue encoding.

3861 Unify JSC::IdentifierTable and WebCore::AtomicStringTable implementations.
3862
3863 These two classes both implement a HashSet of uniqued StringImpls, with
3864 translator classes to avoid unnecessary object creation. The only difference
3865 between the classes is which flag (isIdentifier or inTable) is set.
3866 Combine the two classes using a template predicated on which flag to use.
3867
3868 New class AtomicStringTable created, containing all the goodness from
3869 IdentifierTable & AtomicStringTable, expect for Identifier's literalTable,
3870 which has been moved onto JSGlobalData. Removed duplicate string translator
3871 classes. Renamed StringImpl's inTable flag to more explicit 'isAtomic',
3872 and set this on the empty string (which matches Identifier behaviour, and
3873 removes a redundant check for zero-length).

4357 Bug 37828 - Move WebCore's String classes to WTF
4358
4359 Move these classes up to WTF so they are available to all clients of WTF (in
4360 particular JSC).
4361
4362 As a first patch, making the most minimal change possible, since this patch
4363 could easily grow rather large since we'll have to change every class forward
4364 declaration ( e.g. every "namespace WebCore { class String; }" much change to
4365 "namespace WTF { class String; }").
4366
4367 Moving the files, but leaving the classes logically in the WebCore namespace -
4368 which is technically a layering violation - I'll come back and fix this up in a
4369 subsequent patch.

4708 Mac OS X: Use deployment target to determine whether memory tagging should be enabled
4709 https://bugs.webkit.org/show_bug.cgi?id=34888
4710
4711 When building on (Snow) Leopard but targeting Tiger
4712 (TARGETING_TIGER defined, BUILDING_ON_TIGER not defined),
4713 WebKit would crash on Tiger because the tags passed to mmap
4714 caused those function calls to fail.
4715
4716 Conversely, when building on Tiger but targeting Leopard
4717 (BUILDING_ON_TIGER defined, TARGETING_LEOPARD defined), WebKit
4718 would crash on Leopard because the tags passed to vm_map and
4719 vm_allocate caused those function calls to fail.
4720
4721 Solution: Use TARGETING_TIGER rather than BUILDING_ON_TIGER to
4722 govern the tag definitions. Use the same tags for vm_map and
4723 vm_allocate regardless of target, since they work on
4724 both. Fall back to the mmap tags that work on Tiger (that is,
4725 "no tags") if targeting Tiger, since those tags also work on

5428 Bug 36519 - JSGlobalContextRelease is unnecessarily slow
5429
5430 Since [ http://trac.webkit.org/changeset/35917 ], calling
5431 JSGlobalContextRelease always triggers a GC heap collection
5432 (if not a full destroy). As per 35917's changelog "This is
5433 only really necessary when the (JSGlobalObject's) last
5434 reference is released, but there is no way to determine that,
5435 and no harm in collecting slightly more often."
5436
5437 Well, we now know of cases of API clients who are harmed by
5438 the performance penalty of collecting too often, so it's time
5439 to add a way to determine whether a call to JSGlobalContextRelease
5440 is removing the last protect from it's global object. If further
5441 protects are retaining the global object (likely from other
5442 JSGlobalContextRefs), then don't trigger a GC collection.
5443
5444 * API/JSContextRef.cpp:

5589 New class was created; the QScriptSyntaxCheckResult which main
5590 responsibility is to provide results of the ECMA Script code
5591 syntax check. The class is not fully functional as the JSC C API
5592 doesn't expose an error column number, but it is a good start point
5593 for a future development.
5594
5595 [Qt] QtScript functionality should be extended by syntax checking.

6537 JSC should cache int to Identifier conversion as it does for ordinary strings
6538 https://bugs.webkit.org/show_bug.cgi?id=35814
6539
6540 Make the NumericStrings cache cache unsigned ints in addition to signed.
6541 We keep them separate from the int cache as it both simplifies code, and
6542 also because the unsigned path is exclusive to property access and therefore
6543 seems to have different usage patterns.
6544
6545 The primary trigger for the unsigned to Identifier propertyName conversion
6546 is the construction of array-like objects out of normal objects. Given these
6547 tend to be relative small numbers, and the array-like behaviour lends itself
6548 to sequential values this patch also adds a non-colliding cache for all small
6549 numbers.

6573 new parameters to allow us to pass enough information to the stub
6574 function to allow us to call the C function correctly. Logically
6575 this shouldn't actually be necessary as all of these functions ignore
6576 the identifier, but removing the ident parameter would require
6577 somewhat involved changes to the way we implement getOwnPropertySlot,
6578 etc.

6661 QScriptValue::isObject fix.
6662
6663 Fix broken internal state evaluation from JSValue to JSNative / JSObject.
6664 New function was introduced which should take care about promoting
6665 JSValue state inside QScriptValuePrivate. It should be used instead of a
6666 direct JSC C API call.
6667
6668 The bug exposed a weakness in autotest suite, as the QScriptValuePrivate
6669 is based on state machine with lazy state evaluation, there is a possibility
6670 that serial sequencial calls to the same public const function could return
6671 different results. The patch fix the issue.

7053 https://bugs.webkit.org/show_bug.cgi?id=35563
7054
7055 This removes the PropertySlot argument from getter functions, and makes them directly
7056 pass the slot base. This makes the semantics for the functions match that of the
7057 indexing getters.
7058
7059 On the down side, this means that we can no longer simply use a proxy function for
7060 JS getters, so we now add another marker value to indicate that a getter is present
7061 and branch accordingly.
7062
7063 Against all rationality sunspider reports this as a perf win, but i suspect it's just noise.

7134 Bug 35537 - put_by_id does will incorrectly cache writes where a specific value exists,
7135 where at the point of caching the same value is being written.
7136
7137 When performing a put_by_id that is replacing a property already present on the object,
7138 there are three interesting cases regarding the state of the specific value:
7139
7140 (1) No specific value set - nothing to do, leave the structure in it's current state,
7141 can cache.
7142 (2) A specific value was set, the new put is not of a specified value (i.e. function),
7143 or is of a different specific value - in these cases we need to perform a despecifying
7144 transition to clear the specific value in the structure, but having done so this is a
7145 normal property so as such we can again cache normally.
7146 (3) A specific value was set, and we are overwriting with the same value - in these cases
7147 leave the structure unchanged, but since a specific value is set we cannot cache this
7148 put (we would need the JIT to dynamically check the value being written matched).
7149
7150 Unfortunately, the current behaviour does not match this. the checks for a specific value
7151 being present & the value matching are combined in such a way that in case (2), above we
7152 will unnecessarily prevent the transition being cached, but in case (3) we will incorrectly
7153 fail to prevent caching.
7154
7155 The bug exposes itself if multiple puts of the same specific value are performed to a
7156 property, and erroneously the put is allowed to be cached by the JIT. Method checks may be
7157 generated caching calls of this structure. Subsequent puts performed from JIT code may
7158 write different values without triggering a despecify transition, and as such cached method
7159 checks will continue to pass, despite the value having changed.

7274 Race condition in JSPropertyNameIterator and Structure destruction
7275 https://bugs.webkit.org/show_bug.cgi?id=35398
7276
7277 JSPropertyNameIterator and Structure have a cyclic dependency that they
7278 manage by clearing the appropriate reference in each other during their
7279 destruction. However if the Structure is destroyed while the
7280 JSPropertyNameIterator is dead but not yet finalized the Structures
7281 WeakGCPtr will return null, and so prevent Structure from clearing
7282 the m_cachedStructure pointer of the iterator. When the iterator is
7283 then finalised the m_cachedStructure is invalid, and the attempt to
7284 clear the structures back reference fails.
7285
7286 To fix this we simply make JSPropertyNameIterator keep the Structure
7287 alive, using the weak pointer to break the ref cycle.

7628 JSString::getIndex() calls value() to resolve the string value (is a rope)
7629 to a UString, then passes the result to jsSingleCharacterSubstring without
7630 checking for an exception. In case of out-of-memory the returned UString
7631 is null(), which may result in an out-of-buounds substring being created.
7632 This is bad.
7633
7634 Simple fix is to be able to get an index from a rope without resolving to
7635 UString. This may be a useful optimization in some test cases.
7636
7637 The same bug exists in some other methods is JSString, these can be fixed

7717
7718 Improve the performance of getter dispatch by making it possible
7719 for the interpreter to cache the GetterSetter object lookup.
7720
7721 To do this we simply need to make PropertySlot aware of getters
7722 as a potentially cacheable property, and record the base and this
7723 objects for a getter access. This allows us to use more-or-less
7724 identical code to that used by the normal get_by_id caching, with
7725 the dispatch being the only actual difference.
7726

7844 Leaks tool reports false memory leaks due to Rope implementation.
7845
7846 A rope is a recursive data structure where each node in the rope holds a set of
7847 pointers, each of which may reference either a string (in UStringImpl form) or
7848 another rope node. A low bit in each pointer is used to distinguish between
7849 rope & string elements, in a fashion similar to the recently-removed
7850 PtrAndFlags class (see https://bugs.webkit.org/show_bug.cgi?id=33731 ). Again,
7851 this causes a problem for Leaks - refactor to remove the magic pointer
7852 mangling.
7853
7854 Move Rope out from JSString.h and rename to URopeImpl, to match UStringImpl.
7855 Give UStringImpl and URopeImpl a common parent class, UStringOrRopeImpl.
7856 Repurpose an otherwise invalid permutation to flags (static & should report
7857 memory cost) to identify ropes.
7858
7859 This allows us to change the rope's fibers to interrogate the object rather
7860 than storing a bool within the low bits of the pointer (or in some cases the
7861 use of a common parent class removes the need to determine the type at all -
7862 there is a common interface to ref or get the length of either ropes or strings).

8006 Many false leaks in release builds due to PtrAndFlags
8007
8008 StructureTransitionTable was effectively a smart pointer type,
8009 one machine word in size and wholly contained as a member of
8010 of Structure. It either pointed to an actual table, or could
8011 be used to describe a single transtion entry without use of a
8012 table.
8013
8014 This, however, worked by using a PtrAndFlags, which is not
8015 compatible with the leaks tool. Since there is no clear way to
8016 obtain another bit for 'free' here, and since there are bits
8017 available up in Structure, merge this functionality back up into
8018 Structure. Having this in a separate class was quite clean
8019 from an enacapsulation perspective, but this solution doesn't
8020 seem to bad - all table access is now intermediated through the
8021 Structure::structureTransitionTableFoo methods, keeping the
8022 optimization fairly well contained.
8023
8024 This was the last use of PtrAndFlags, so removing the file too.

8381 Keep weak references, rather than protected references, to cached for-in
8382 property name enumerators.
8383
8384 One problem with protected references is that a chain like
8385 [ gc object 1 ] => [ non-gc object ] => [ gc object 2 ]
8386 takes two GC passes to break, since the first pass collects [ gc object 1 ],
8387 releasing [ non-gc object ] and unprotecting [ gc object 2 ], and only
8388 then can a second pass collect [ gc object 2 ].
8389
8390 Another problem with protected references is that they can keep a bunch
8391 of strings alive long after they're useful. In SunSpider and a few popular
8392 websites, the size-speed tradeoff seems to favor weak references.

8890 Change UStringImpl::create to CRASH if the string cannot be allocated,
8891 rather than returning a null string (which will behave like a zero-length
8892 string if used).
8893
8894 Also move createRep function from UString to become new overloaded
8895 UStringImpl::create methods. In doing so, bring their behaviour closer to
8896 being in line with WebCore::StringImpl, in removing the behaviour that they
8897 can be used to produce null UStrings (ASSERT the char* provided is non-null).
8898 This behaviour of converting null C-strings to null UStrings is inefficient
8899 (cmompared to just using UString::null()), incompatible with WebCore::StringImpl's
8900 behaviour, and may generate unexpected behaviour, since in many cases a null
8901 UString can be used like an empty string.
8902
8903 With these changes UStringImpl need not have a concept of null impls, we can
8904 start transitioning this to become an implementation detail of UString, that
8905 internally it chooses to use a null-object rather than an actually zero impl
8906 pointer.

8958
8959 With USE_SYSTEM_MALLOC=1, fastMalloc and fastCalloc call CRASH()
8960 if the return value of malloc and calloc is 0.
8961
8962 However, these functions can return 0 when the request size is 0.
8963 Libc manual says, "If size is 0, then malloc() returns either NULL,
8964 or a unique pointer value that can later be successfully passed to free()."
8965 Though malloc returns a unique pointer in most systems,
8966 0 can be returned in some systems. For instance, BREW's MALLOC returns 0
8967 when size is 0.
8968
8969 If malloc or calloc returns 0 due to allocation size, increase the size
8970 to 1 and try again.

9241
9242 This was caused by the use of m_offset to determine the offset of
9243 a new property into the property storage. This patch corrects
9244 the effected cases by incorporating the anonymous slot count. It
9245 also removes the duplicate copy of anonymous slot count from the
9246 property table as keeping this up to date merely increased the
9247 chance of a mismatch. Finally I've added a large number of
9248 assertions in an attempt to prevent such a bug from happening
9249 again.
9250
9251 With the new assertions in place the existing anonymous slot tests
9252 all fail without the m_offset fixes.

9650 WebKit needs a mechanism to catch stale HashMap entries
9651
9652 It is very difficult to catch stale pointers that are HashMap keys - since a pointer's hash
9653 is just its value, it is very unlikely that any observable problem is reproducible.
9654
9655 This extends hash table consistency checks to check that pointers are referencing allocated
9656 memory blocks, and makes it possible to invoke the checks explicitly (it is not feasible
9657 to enable CHECK_HASHTABLE_CONSISTENCY by default, because that affects performance too much).
9658
9659 * wtf/HashMap.h: (WTF::::checkConsistency): Call through to HashTable implementation. We can
9660 add similar calls to HashSet and HashCountedSet, but I haven't seen hard to debug problems
9661 with those yet.

10721 Make naming & behaviour of UString[Impl] methods more consistent.
10722 https://bugs.webkit.org/show_bug.cgi?id=33702
10723
10724 UString::create() creates a copy of the UChar* passed, but UStringImpl::create() assumes
10725 that it should assume ownership of the provided buffer (with UString::createNonCopying()
10726 and UStringImpl::createCopying() providing the alternate behaviours). Unify on create()
10727 taking a copy of the provided buffer. For non-copying cases, use the name 'adopt', and
10728 make this method take a Vector<UChar>&. For cases where non-copying construction was being
10729 used, other than from a Vector<UChar>, change the code to allocate the storage along with
10730 the UStringImpl using UStringImpl::createUninitialized(). (The adopt() method also more
10731 closely matches that of WebCore::StringImpl).
10732
10733 Also, UString::createUninitialized() and UStringImpl::createUninitialized() have incompatible
10734 behaviours, in that the UString form sets the provided UChar* to a null or non-null value to
10735 indicate success or failure, but UStringImpl uses the returned PassRefPtr<UStringImpl> to
10736 indicate when allocation has failed (potentially leaving the output Char* uninitialized).
10737 This is also incompatible with WebCore::StringImpl's behaviour, in that
10738 StringImpl::createUninitialized() will CRASH() if unable to allocate. Some uses of
10739 createUninitialized() in JSC are unsafe, since they do not test the result for null.
10740 UStringImpl's indication is preferable, since we may want a successful call to set the result
10741 buffer to 0 (specifically, StringImpl returns 0 for the buffer where createUninitialized()
10742 returns the empty string, which seems reasonable to catch bugs early). UString's method
10743 cannot support UStringImpl's behaviour directly, since it returns an object rather than a
10744 pointer.
10745 - remove UString::createUninitialized(), replace with calls to UStringImpl::createUninitialized()
10746 - create a UStringImpl::tryCreateUninitialized() form UStringImpl::createUninitialized(),
10747 with current behaviour, make createUninitialized() crash on failure to allocate.
10748 - make cases in JSC that do not check the result call createUninitialized(), and cases that do
10749 check call tryCreateUninitialized().
10750
10751 Rename computedHash() to existingHash(), to bring this in line wih WebCore::StringImpl.

10845 Three quick fixes to UStringImpl.
10846 - The destroy() method can be switched back to a normal destructor; since we've switched
10847 the way we protect static strings to be using an odd ref-count the destroy() won't abort.
10848 - The cost() calculation logic was wrong. If you have multiple JSStrings wrapping substrings
10849 of a base string, they would each report the full cost of the base string to the heap.
10850 Instead we should only be reporting once for the base string.
10851 - Remove the overloaded new operator calling fastMalloc, replace this with a 'using' to pick
10852 up the implementation from the parent class.

11371 <rdar://problem/7296920> REGRESSION: WebKit fails to start PeaceKeeper benchmark
11372
11373 Test: fast/js/webcore-string-comparison.html
11374
11375 In r49365, some code was moved from JSString.cpp to JSString.h, and as a result, WebCore
11376 got a way to directly instantiate JSStrings over DLL borders. Since vftable for JSString was
11377 not exported, objects created from WebCore got a different vptr, and JavaScriptCore
11378 optimizations that relied on vptr of all JSString objects being equal failed.
11379

11507 Remove m_identifierTable pointer from UString
11508
11509 Currently every string holds a pointer so that during destruction,
11510 if a string has been used as an identifier, it can remove itself
11511 from the table. By instead accessing the identifierTable via a
11512 thread specific tracking the table associated with the current

12386 Changed Register constructors to assignment operators, to streamline
12387 moving values into registers. (In theory, there's no difference between
12388 the two, since the constructor should just inline away, but there seems
12389 to be a big difference in the addled mind of the GCC optimizer.)
12390
12391 In the interpreter, this is a 3.5% SunSpider speedup and a 1K-2K

13020 Refactor construction of simple strings to avoid string concatenation.
13021
13022 Building strings through concatenation has a memory and performance cost -
13023 a memory cost since we must over-allocate the buffer to leave space to append
13024 into, and performance in that the string may still require reallocation (and
13025 thus copying during construction). Instead move the full construction to
13026 within a single function call (makeString), so that the arguments' lengths
13027 can be calculated and an appropriate sized buffer allocated before copying
13028 any characters.

13688 conway benchmark spends half it's time in op_less (jump fusion fails)
13689 https://bugs.webkit.org/show_bug.cgi?id=32190
13690
13691 <1% speedup on SunSpider and V8
13692 2x speedup on "conway" benchmark
13693
13694 Two optimizations:
13695 1) Improve codegen for logical operators &&, || and ! in a condition context
13696
13697 When generating code for combinations of &&, || and !, in a
13698 condition context (i.e. in an if statement or loop condition), we
13699 used to produce a value, and then separately jump based on its
13700 truthiness. Now we pass the false and true targets in, and let the
13701 logical operators generate jumps directly. This helps in four
13702 ways:
13703
13704 a) Individual clauses of a short-circuit logical operator can now
13705 jump directly to the then or else clause of an if statement (or to
13706 the top or exit of a loop) instead of jumping to a jump.
13707
13708 b) It used to be that jump fusion with the condition of the first
13709 clause of a logical operator was inhibited, because the register
13710 was ref'd to be used later, in the actual condition jump; this no
13711 longer happens since a jump straight to the final target is
13712 generated directly.
13713
13714 c) It used to be that jump fusion with the condition of the second
13715 clause of a logical operator was inhibited, because there was a
13716 jump target right after the second clause and before the actual
13717 condition jump. But now it's no longer necessary for the first
13718 clause to jump there so jump fusion is not blocked.
13719
13720 d) We avoid generating excess mov statements in some cases.
13721
13722 As a concrete example this source:
13723
13724 if (!((x < q && y < q) || (t < q && z < q))) {
13725 // ...
13726 }
13727
13728 Used to generate this bytecode:
13729
13730 [ 34] less r1, r-15, r-19
13731 [ 38] jfalse r1, 7(->45)
13732 [ 41] less r1, r-16, r-19
13733 [ 45] jtrue r1, 14(->59)
13734 [ 48] less r1, r-17, r-19
13735 [ 52] jfalse r1, 7(->59)
13736 [ 55] less r1, r-18, r-19
13737 [ 59] jtrue r1, 17(->76)
13738
13739 And now generates this bytecode (also taking advantage of the second optimization below):
13740
13741 [ 34] jnless r-15, r-19, 8(->42)
13742 [ 38] jless r-16, r-19, 26(->64)
13743 [ 42] jnless r-17, r-19, 8(->50)
13744 [ 46] jless r-18, r-19, 18(->64)
13745
13746 Note the jump fusion and the fact that there's less jump
13747 indirection - three of the four jumps go straight to the target
13748 clause instead of indirecting through another jump.
13749
13750 2) Implement jless opcode to take advantage of the above, since we'll now often generate
13751 a less followed by a jtrue where fusion is not forbidden.

13853 Add a rope representation to JSString. Presently JSString always holds its data in UString form.
13854 Instead, allow the result of a string concatenation to be represented in a tree form - with a
13855 variable sized, reference-counted rope node retaining a set of UString::Reps (or other rope nopes).
13856
13857 Strings must still currently be resolved down to a flat UString representation before being used,
13858 but by holding the string in a rope representation during construction we can avoid copying data
13859 until we know the final size of the string.

14077 The Intel compiler does not support the __has_trivial_constructor type
14078 trait. The Intel Compiler can report itself as _MSC_VER >= 1400. The
14079 reason for that is that the Intel Compiler depends on the Microsoft
14080 Platform SDK, and in order to try to be "fully" MS compatible it will
14081 "pretend" to be the same MS compiler as was shipped with the MS PSDK.
14082 (Thus, compiling with win32-icc with VC8 SDK will make the source code

14272 Part 1/3 of <rdar://problem/7377477> REGRESSION: Many web pages fail to render after interesting script runs in isolated world
14273
14274 Some clients of the JavaScriptCore API expect to be able to make callbacks over the JSC API,
14275 and for this to automagically cause execution to take place in the world associated with the
14276 global object associated with the ExecState (JSContextRef) passed. However this is not how
14277 things work - the world must be explicitly set within WebCore.
14278
14279 Making this work just for API calls to evaluate & call will be a far from perfect solution,
14280 since direct (non-API) use of JSC still relies on WebCore setting the current world correctly.
14281 A better solution would be to make this all work automagically all throughout WebCore, but this
14282 will require more refactoring.
14283
14284 Since the API is in JSC but worlds only exist in WebCore, add callbacks on the JSGlobalData::ClientData
14285 to allow it to update the current world on entry/exit via the JSC API. This is temporary duck
14286 tape, and should be removed once the current world no longer needs to be explicitly tracked.

15155 Implemented a timezone cache not based on Mac OS X's notify_check API.
15156
15157 If the VM calculates the local timezone offset from UTC, it caches the
15158 result until the end of the current VM invocation. (We don't want to cache
15159 forever, because the user's timezone may change over time.)

15244 Currently behaviour of shifts of a magnitude > 0x1f is undefined.
15245 Instead defined that all shifts are masked to this range. This makes a lot of
15246 practical sense, both since having undefined behaviour is not particularly
15247 desirable, and because this behaviour is commonly required (particularly since
15248 it is required bt ECMA-262 for shifts).

15288 Fix branchDouble behaviour on ARM THUMB2 JIT.
15289
15290 The x86 branchDouble behaviour is reworked, and all JIT
15291 ports should follow the x86 port. See bug 31104 and 31151
15292
15293 This patch contains a fix for the traditional ARM port

15358 Fix branchDouble behaviour on ARM THUMB2 JIT.
15359
15360 The ARMv7 JIT is currently using ARMv7Assembler::ConditionEQ to branch
15361 for DoubleEqualOrUnordered, however this is incorrect - ConditionEQ won't
15362 branch on unordered operands. Similarly, DoubleLessThanOrUnordered &
15363 DoubleLessThanOrEqualOrUnordered use ARMv7Assembler::ConditionLO &
15364 ARMv7Assembler::ConditionLS, whereas they should be using
15365 ARMv7Assembler::ConditionLT & ARMv7Assembler::ConditionLE.

15406
15407 We do this by having the registerName function return information about the constant if the register

15409 be converted to member functions of CodeBlock so that the constant value can be retrieved. The
15410 ExecState also needs to be threaded down through these functions so that it can be passed on to

15814 When using -fvisibility=hidden to hide all internal symbols by default
15815 the malloc symbols will be hidden as well. For memory instrumentation

16769 Eliminated some legacy bytecode weirdness.
16770
16771 Use vPC[x] subscripting instead of ++vPC to access instruction operands.
16772 This is simpler, and often more efficient.
16773
16774 To support this, and to remove use of hard-coded offsets in bytecode and
16775 JIT code generation and dumping, calculate jump offsets from the beginning
16776 of an instruction, rather than the middle or end.

18274 SNES is too slow
18275 https://bugs.webkit.org/show_bug.cgi?id=29534
18276
18277 The problem was that the emulator used multiple classes with
18278 more properties than our dictionary cutoff allowed, this resulted
18279 in more or less all critical logic inside the emulator requiring
18280 uncached property access.
18281
18282 Rather than simply bumping the dictionary cutoff, this patch
18283 recognises that there are two ways to create a "dictionary"
18284 structure. Either by adding a large number of properties, or
18285 by removing a property. In the case of adding properties we
18286 know all the existing properties will maintain their existing
18287 offsets, so we could cache access to those properties, if we
18288 know they won't be removed.
18289
18290 To make this possible, this patch adds the logic required to
18291 distinguish a dictionary created by addition from one created
18292 by removal. With this logic in place we can now cache access
18293 to objects with large numbers of properties.
18294
18295 SNES performance improved by more than 6x.

18412 Currently defineOwnProperty uses a delete followed by a put to redefine
18413 attributes of a property, clearly this is less efficient than it could be
18414 but we can improve this if it needs to be possible in future.

18570 "illegal operand" for m_attributesInPrevious in structure.ccp
18571 (when calling make_pair functions).

18574
18575 Initial patch explicitly casted m_attributesInPrevious

18656 ThreadSpecific::Data. Unlike pthread, Qt is object oriented, and does
18657 not support the calling of a static utility function when the thread
18658 is about to close. In this patch we call the ThreadSpecific::destroy()
18659 utility function from the destructor of ThreadSpecific::Data. Moreover,
18660 since Qt resets all thread local values to 0 before the calling of the
18661 appropriate destructors, we set back the pointer to its original value.
18662 This is necessary because the get() method of the ThreadSpecific
18663 object may be called during the exuction of the destructor.

18675 Allow anonymous storage inside JSObject
18676 https://bugs.webkit.org/show_bug.cgi?id=29168
18677
18678 Add the concept of anonymous slots to Structures so that it is
18679 possible to store references to values that need marking in the
18680 standard JSObject storage buffer. This allows us to reduce the
18681 malloc overhead of some objects (by allowing them to store JS
18682 values in the inline storage of the object) and reduce the
18683 dependence of custom mark functions (if all an objects children
18684 are in the standard object property storage there's no need to
18685 mark them manually).

19222
19223 Part two.
19224
19225 Make some improvements to garbage collection code:
19226
19227 1) Create a runtime assertion that catches any classes that
19228 override markChildren but have the HasDefaultMark bit set.
19229 2) Remove checks of the mark bit outside the MarkStack::append
19230 function; they are redundant.
19231 3) Improve the efficiency of the asObject and asArray functions
19232 when called on JSCell* to avoid a round trip to JSValue.
19233 4) Make more callers use the checked asCell and asObject
19234 casting functions rather than unchecked casts.
19235 5) Removed the JSCell::marked function and other GC-related
19236 functions because these operations are no longer things that
19237 code other than the core GC code needs to do directly. Fixed
19238 callers that were calling them.
19239
19240 * runtime/Collector.cpp:
19241 (JSC::Heap::markConservatively): Removed unneeded call to MarkStack::drain.
19242 (JSC::Heap::markProtectedObjects): Removed unneeded check of the mark
19243 bit and call to MarkStack::drain.
19244 (JSC::Heap::collect): Removed unneeded checks of the mark bit and also
19245 changed call to SmallStrings::mark to call markChildren instead to match
19246 the rest of the objects.
19247 (JSC::typeName): Removed unneeded cast to JSObject*.
19248
19249 * runtime/JSArray.h:
19250 (JSC::asArray): Added an overload for JSCell* and changed the JSValue
19251 version to call it. Removed some unneeded casts.
19252 (JSC::JSArray::markChildrenDirect): Marked this function inline. It's in
19253 a header, and if not marked inline this could lead to linking problems.
19254 (JSC::MarkStack::markChildren): Added. This helper function is used by
19255 the drain function to avoid repating code. Also added the code here to
19256 check fro default mark violations in debug code. If a markChildren
19257 function adds something to the mark stack, but the type info claimed
19258 hasDefaultMark was true, then we will get an assertion now. Also fixed
19259 the assertion about the mark bit to use the Heap function directly
19260 because we don't have a JSCell::marked function any more.
19261 (JSC::MarkStack::drain): Changed a local variable from "v" to "value",
19262 and from "currentCell" to "cell". Changed to call markChildren in two
19263 places instead of repeating a chain of if statements twice. Changed
19264 code that reads and writes the mark bit to use Heap::isCellMarked and
19265 Heap::markCell so we can eliminate the JSCell::marked and
19266 JSCell::markCellDirect functions.
19267
19268 * runtime/JSCell.h: Removed JSCell's markCellDirect and marked member
19269 functions. Added a comment explaining that asCell should be deprecated
19270 in favor of the JSValue asCell member function.
19271 (JSC::MarkStack::append): Added the assertion that catches callers
19272 that have set the HasDefaultMark bit incorrectly. Changed
19273 code that reads and writes the mark bit to use Heap::isCellMarked and
19274 Heap::markCell so we can eliminate the JSCell::marked and
19275 JSCell::markCellDirect functions. Moved the overload of
19276 MarkStack::append for JSValue here so it can call through to the cell
19277 version. The old version had a copy of all the code instead, but that
19278 repeated the conversion from JSValue to JSCell* and the check for
19279 whether a value is a cell multiple times.
19280 (JSC::Structure::markAggregate): Moved this function here to avoid
19281 dependencies for Structure.h, since this calls MarkStack::append.
19282
19283 * runtime/JSObject.cpp:
19284 (JSC::JSObject::markChildren): Added code to clear
19285 m_isCheckingForDefaultMarkViolation so the marking done by JSObject
19286 doesn't trigger the assertion.
19287
19288 * runtime/JSValue.h: Moved some stray includes that were outside the
19289 header guard inside it. Not sure how that happened! Removed the
19290 GC-related member functions markChildren, hasChildren, marked, and
19291 markDirect.
19292
19293 * runtime/JSWrapperObject.h: Made markChildren private.
19294 (JSC::JSWrapperObject::createStructure): Added. Fixes a bug where the
19295 HasDefaultMark bit was set.
19296
19297 * runtime/MarkStack.h: Added m_isCheckingForDefaultMarkViolation and
19298 initialized it to false. Moved the append function body from here to
19299 JSCell.h. Added a declaration of a private markChildren function used
19300 inside the drain function.
19301
19302 * runtime/SmallStrings.cpp:
19303 (JSC::SmallStrings::markChildren): Changed the name and style of this
19304 function to match other functions. This allows us to share the normal
19305 mark stack code path.
19306
19307 * runtime/SmallStrings.h: Changed the name and interface of mark to
19308 the more-normal markChildren style.
19309
19310 * runtime/Structure.h: Moved the body of markAggregate into the
19311 JSCell.h to avoid a circular dependency with JSCell.h.

19767 [ES5] Implement getOwnPropertyDescriptor

19769
19770 Implement the core runtime support for getOwnPropertyDescriptor.
19771 This adds a virtual getOwnPropertyDescriptor method to every class
19772 that implements getOwnPropertySlot that shadows the behaviour of
19773 getOwnPropertySlot. The alternative would be to make getOwnPropertySlot
19774 (or PropertySlots in general) provide property attribute information,

19869 How many copies of the parameters do you need?
19870 https://bugs.webkit.org/show_bug.cgi?id=28701
19871
19872 The function parameters in JSC get copied a lot - and unnecessarily so.
19873
19874 Originally this happened due to duplicating FunctionBodyNodes on recompilation,
19875 though the problem has been exacerbated by copying the parameters from the
19876 original function body onto the executable, then back onto the real body that
19877 will be generated (this happens on every function). And this is all made worse
19878 since the data structures in question are a little ugly - C style arrays of C++
19879 objects containing ref counts, so they need a full copy-construct (rather than
19880 a simple memcpy).
19881
19882 This can all be greatly simplified by just punting the parameters off into
19883 their own ref-counted object, and forgoing all the copying.
19884
19885 ~no performance change, possible slight progression.

20206 Changed ElementNode, PropertyNode, ArgumentsNode, ParameterNode,
20207 CaseClauseNode, ClauseListNode, and CaseBlockNode to use ParserArenaFreeable

20281 Restructure Executable types so that host functions do not hold a FunctionExecutable.
20282 https://bugs.webkit.org/show_bug.cgi?id=28621
20283
20284 All JSFunction objects have a pointer to an Executable*. This is currently always a
20285 FunctionExecutable, however this has a couple of drawbacks. Host functions do not
20286 store a range of information that the FunctionExecutable provides (source, name,
20287 CodeBlock & information presently held on the FunctionBodyNode).
20288
20289 [ * nearly all... see below! ]
20290
20291 Instead, make JSFunctions hold a pointer to an ExecutableBase, move fields specific
20292 to JS sourced executable types (source, node) into a new subclass (ScriptExecutable),
20293 and create a new NativeExecutable type. We now provide a new method in JSFunction
20294 to access & downcast to FunctionExecutable, but in doing so we can make an early
20295 check (with an ASSERT) to ensure that the Executable read from a function will only
20296 be treated as a FunctionExecutable (and thus the JS sepcific fields will only be
20297 accessed) if the JSFunction is not a host function.
20298
20299 There is one JSFunction that currently does not have an Executable, which is the
20300 object created to allow us to read out the vtable pointer. By making this change
20301 we can also add a new Executable type fror this object (VPtrHackExecutable).
20302 Since this means that really all JSFunctions have an Executable we no longer have
20303 to null-check m_executable before us it - particularly in isHostFunction().
20304
20305 This patch removes CacheableEvalExecutable, since all subclasses of ExecutableBase
20306 can now be ref-counted - since both JSFunction holds (and ref-counts) an ExecutableBase
20307 that might be a FunctionExecutable or a NativeExecutable. This does now mean that all
20308 ProgramExecutables and EvalExecutables (unnecessarily) provide an interface to be
20309 ref-counted, however this seems less-bad than host functions unnecessarily providing
20310 interface to access non-host specific information.
20311
20312 The class hierarcy has changed from this:
20313
20314 - ExecutableBase
20315 - ProgramExecutable
20316 - EvalExecutable
20317 - CacheableEvalExecutable (also RefCounted by multiple-inheritance)
20318 - FunctionExecutable (also RefCounted by multiple-inheritance, 'special' FunctionExecutable also used for host functions)
20319
20320 To this:
20321
20322 - RefCounted
20323 - ExecutableBase
20324 - NativeExecutable
20325 - VPtrHackExecutable
20326 - ScriptExecutable
20327 - ProgramExecutable
20328 - EvalExecutable
20329 - FunctionExecutable

20399 Code generation needs to be able to walk the entire scopechain in some

20569 Will produce a unique structure on every iteration, meaning that all
20570 caching is defeated and there is a significant amount of structure churn.
20571
20572 The fix is to return the transition to its original form where it is
20573 keyed off a property name + attributes tuple, but have each transition
20574 support an optional transition on a specific value.

20600 Remove FunctionCodeBlock.

20602
20603 These only exist to allow JIT code to dereference properties off the
20604 CodeBlock for any callee, regardless of whether it is a host function.
20605
20606 Instead just use the FunctionExecutable. Copy the m_parameters field
20607 from the CodeBlock into the Executable, and use this to distinguish
20608 between host functions, functions that have been bytecompiled, and
20609 functions that have not.
20610
20611 m_parameters is moved to ExecutableBase rather than FunctionExecutable
20612 so that (as a separate change) we can move make a separate class of
20613 executable for host code, which is not devived from FunctionExecutable
20614 (host code does not feature any of the properties that normal executable
20615 do and will provide, such as source, attributes, and a parsed name).

20993 Fix 300,000+ leaks seen during the regression tests.
20994
20995 EvalCodeCache::get was heap-allocating an EvalExecutable instance without adopting the initial reference.
20996 While fixing this we noticed that EvalExecutable was a RefCounted type that was sometimes stack allocated.
20997 To make this cleaner and to prevent clients from attempting to ref a stack-allocated instance, we move the
20998 refcounting down to a new CacheableEvalExecutable class that derives from EvalExecutable. EvalCodeCache::get
20999 now uses CacheableEvalExecutable::create and avoids the leak.

21340 [ES5] Arguments object should inherit from Array
21341 https://bugs.webkit.org/show_bug.cgi?id=28298
21342
21343 Make the Arguments object conform to the behaviour specified in ES5.
21344 The simple portion of this is to make Arguments use Array.prototype
21345 as its prototype rather than Object.prototype.
21346
21347 The spec then requires us to set instance.constructor to the pristine
21348 Object constructor, and instance.toString and instance.toLocaleString
21349 to the pristine versions from Object.prototype. To do this we now
21350 make the ObjectPrototype constructor return its toString and
21351 toLocaleString functions (similar to the call and apply functions
21352 from FunctionPrototype).
21353
21354 Oddly enough this reports itself as a slight win, but given the code
21355 isn't hit in the tests that claim to have improved I put this down to
21356 code motion.

21424 Devirtualise marking

21426
21427 Add a bit to TypeInfo to indicate that an object uses the standard
21428 JSObject::markChildren method. This allows us to devirtualise marking
21429 of most objects (though a branch is still needed). We also add a branch
21430 to identify arrays thus devirtualising marking in that case as well.
21431
21432 In order to make the best use of this devirtualisation I've also reworked
21433 the MarkStack::drain() logic to make the iteration more efficient.

22081 Stack overflow crash in JavaScript garbage collector mark pass
22082 https://bugs.webkit.org/show_bug.cgi?id=12216
22083
22084 Make the GC mark phase iterative by using an explicit mark stack.
22085 To do this marking any single object is performed in multiple stages
22086 * The object is appended to the MarkStack, this sets the marked
22087 bit for the object using the new markDirect() function, and then
22088 returns
22089 * When the MarkStack is drain()ed the object is popped off the stack
22090 and markChildren(MarkStack&) is called on the object to collect
22091 all of its children. drain() then repeats until the stack is empty.
22092
22093 Additionally I renamed a number of methods from 'mark' to 'markAggregate'
22094 in order to make it more clear that marking of those object was not
22095 going to result in an actual recursive mark.

23602 Fixed some ASSERTs in http/tests/security.
23603
23604 These ASSERTs were introduced by http://trac.webkit.org/changeset/45057,
23605 but the underlying problem was actually older. http://trac.webkit.org/changeset/45057
23606 just exposed the problem by enabling optimization in more cases.
23607
23608 The ASSERTs fired because we tested PropertySlot::slotBase() for validity,
23609 but slotBase() ASSERTs if it's invalid, so we would ASSERT before
23610 the test could happen. Solution: Remove the ASSERT. Maybe it was valid
23611 once, but it clearly goes against a pattern we've deployed of late.
23612
23613 The underlying problem was that WebCore would re-use a PropertySlot in
23614 the case of a forwarding access, and the second use would not completely
23615 overwrite the first use. Solution: Make sure to overwrite m_offset when
23616 setting a value on a PropertySlot. (Other values already get implicitly
23617 overwritten during reuse.)

23894 Remove 'arguments' field from Register union. Having JSCell derived types in the union is
23895 dangerous since it opens the possibility for the field to be written as a raw pointer but
23896 then read as a JSValue. This will lead to statle data being read for the tag, which may
23897 be dangerous. Having removed Arguments* types form Register, all arguments objects must

25764 Move call linking / repatching down from AbstractMacroAssembler into MacroAssemblerARCH classes.
25765 ( https://bugs.webkit.org/show_bug.cgi?id=27527 )
25766
25767 This allows the implementation to be defined per architecture. Specifically this addresses the
25768 fact that x86-64 MacroAssembler implements far calls as a load to register, followed by a call
25769 to register. Patching the call actually requires the pointer load to be patched, rather than
25770 the call to be patched. This is implementation detail specific to MacroAssemblerX86_64, and as
25771 such is best handled there.

26595
26596 When postfix operators operating on locals assign to the same local
26597 the order of operations has to be to store the incremented value, then
26598 store the unmodified number. Rather than implementing this subtle
26599 semantic in the interpreter I've just made the logic explicit in the
26600 bytecode generator, so x=x++ effectively becomes x=ToNumber(x) (for a

27169 Override operator new/delete with const std::nothrow_t& as the second
27170 argument.
27171 https://bugs.webkit.org/show_bug.cgi?id=26792
27172
27173 On Windows CE, operator new/delete, new[]/delete[] with const
27174 std::nothrow_t& must be overrided because some standard template
27175 libraries use these operators.
27176
27177 The problem occurs when memory allocated by new(size_t s, const
27178 std::nothrow_t&) is freed by delete(void* p). This causes the umatched
27179 malloc/free problem.
27180
27181 The patch overrides all new, delete, new[] and delete[] to use
27182 fastMaloc and fastFree consistently.

27203 https://bugs.webkit.org/show_bug.cgi?id=26420
27204
27205 The problem is that the pointer to the memory allocation isn't visible
27206 by "leaks" due to the lower bits being used as flags. The fix is to
27207 make the pointer visible in memory (in debug only). The downside of
27208 this fix that the memory allocated by sharedBuffer will still look like
27209 a leak in non-debug builds when any flags are set.

27440 Specifically, since there is nested invocation (e.g., GlobalCode --> FunctionCode),
27441 the stack overflows immediately on Symbian hardware (max. 80 kB).
27442 Proposed change allocates generator objects on heap.

27900 <https://bugs.webkit.org/show_bug.cgi?id=26532> <rdar://problem/6625385>
27901
27902 We need to make sure that each native function instance correctly unlinks any references to it
27903 when it is collected. Allowing this to happen required a few changes:
27904 * Every native function needs a codeblock to track the link information
27905 * To have this codeblock, every function now also needs its own functionbodynode
27906 so we no longer get to have a single shared instance.

28159 Remove PropertySlot::putValue - PropertySlots should only be used for getting,
28160 not putting. Rename JSGlobalObject::getOwnPropertySlot to hasOwnPropertyForWrite,
28161 which is what it really was being used to ask, and remove some other getOwnPropertySlot
28162 & getOwnPropertySlotForWrite methods, which were unused and likely to lead to confusion.
