  31
  32         Calculate the time offset only if we were able to parse

 100
 101         [Qt] Fix linking on Linux 32-bit.
 102
 103         It was missing the ".text" directive at the top of the file,
 104         indicating that code would follow. Without it, the assembler created
 105         "NOTYPE" symbols, which would result in linker errors.

 192
 193         Reviewed by Oliver Hunt.
 194
 195         Fixed an edge case that could cause the engine not to notice a timezone
 196         change.
 197
 198         No test because this case would require manual intervention to change
 199         the timezone during the test.
 200
 201         SunSpider reports no change.
 202
 203         * runtime/DateInstanceCache.h:
 204         (JSC::DateInstanceCache::DateInstanceCache):
 205         (JSC::DateInstanceCache::reset): Added a helper function for resetting

 209         (JSC::JSGlobalData::resetDateCache): Include resetting the DateInstanceCache
 210         in resetting Date data. (Otherwise, a cache hit could bypass a necessary
 211         timezone update check.)
 212
 213 2009-11-09  Geoffrey Garen  <ggaren@apple.com>
 214
 215         Reviewed by Sam Weinig.
 216
 217         Some manual inlining and constant propogation in Date code.
 218
 219         SunSpider reports a 0.4% speedup on date-*, no overall speedup. Shark

 232         * runtime/DateInstance.h:
 233         (JSC::DateInstance::gregorianDateTime):
 234         (JSC::DateInstance::gregorianDateTimeUTC): Split gregorianDateTime into
 235         a UTC and non-UTC variant, and split each variant into a fast inline
 236         case and a slow out-of-line case.
 237

 264         (JSC::dateProtoFuncGetYear): Updated for the gregorianDateTime change above.
 265
 266 2009-11-09  Geoffrey Garen  <ggaren@apple.com>
 267
 268         Build fix: export a new symbol.
 269
 270         * JavaScriptCore.exp:
 271         * JavaScriptCore.vcproj/JavaScriptCore/JavaScriptCore.def:
 272
 273 2009-11-09  Geoffrey Garen  <ggaren@apple.com>
 274
 275         Reviewed by Sam "Home Wrecker" Weinig.
 276
 277         Added a tiny cache for Date parsing.
 278
 279         SunSpider says 1.2% faster.
 280
 281         * runtime/DateConversion.cpp:
 282         (JSC::parseDate): Try to reuse the last parsed Date, if present.
 283
 284         * runtime/JSGlobalData.cpp:
 285         (JSC::JSGlobalData::resetDateCache):
 286         * runtime/JSGlobalData.h: Added storage for last parsed Date. Refactored
 287         this code to make resetting the date cache easier.
 288
 289         * runtime/JSGlobalObject.h:
 290         (JSC::DynamicGlobalObjectScope::DynamicGlobalObjectScope): Updated for

 300
 301         Can cache prototype lookups on uncacheable dictionaries.
 302         https://bugs.webkit.org/show_bug.cgi?id=31198
 303
 304         Replace fromDictionaryTransition with flattenDictionaryObject and
 305         flattenDictionaryStructure.  This change is necessary as we need to
 306         guarantee that our attempt to convert away from a dictionary structure
 307         will definitely succeed, and in some cases this requires mutating the
 308         object storage itself.

 345
 346         Prepended $$PWD to GENERATED_SOURCES_DIR to avoid potential ambiguities when included from WebCore.pro.
 347         Some preprocessors consider this GENERATED_SOURCES_DIR relative to current invoking dir (e.g., ./WebCore),
 348         and not the working dir of JavaCriptCore.pri (i.e., ../JavaScriptCore/).

 426
 427         https://bugs.webkit.org/show_bug.cgi?id=31197
 428         Implemented a timezone cache not based on Mac OS X's notify_check API.
 429
 430         If the VM calculates the local timezone offset from UTC, it caches the
 431         result until the end of the current VM invocation. (We don't want to cache
 432         forever, because the user's timezone may change over time.)
 433
 434         This removes notify_* overhead on Mac, and, more significantly, removes
 435         OS time and date call overhead on non-Mac platforms.
 436
 437         ~8% speedup on Date microbenchmark on Mac. SunSpider reports maybe a tiny
 438         speedup on Mac. (Speedup on non-Mac platforms should be even more noticeable.)

 445         (JSC::Interpreter::execute):
 446         * runtime/JSGlobalObject.h:
 447         (JSC::DynamicGlobalObjectScope::DynamicGlobalObjectScope): Made the

 517         Currently behaviour of shifts of a magnitude > 0x1f is undefined.
 518         Instead defined that all shifts are masked to this range.  This makes a lot of
 519         practical sense, both since having undefined behaviour is not particularly

1087         When using -fvisibility=hidden to hide all internal symbols by default
1088         the malloc symbols will be hidden as well. For memory instrumentation

3547         SNES is too slow
3548         https://bugs.webkit.org/show_bug.cgi?id=29534
3549
3550         The problem was that the emulator used multiple classes with
3551         more properties than our dictionary cutoff allowed, this resulted
3552         in more or less all critical logic inside the emulator requiring
3553         uncached property access.
3554
3555         Rather than simply bumping the dictionary cutoff, this patch
3556         recognises that there are two ways to create a "dictionary"
3557         structure.  Either by adding a large number of properties, or
3558         by removing a property.  In the case of adding properties we
3559         know all the existing properties will maintain their existing
3560         offsets, so we could cache access to those properties, if we
3561         know they won't be removed.
3562
3563         To make this possible, this patch adds the logic required to
3564         distinguish a dictionary created by addition from one created
3565         by removal.  With this logic in place we can now cache access
3566         to objects with large numbers of properties.
3567
3568         SNES performance improved by more than 6x.

3681         Implement Object.defineProperty.  This requires adding the API to

3684         JSObject::defineOwnProperty that implements the appropriate ES5 semantics.
3685         Currently defineOwnProperty uses a delete followed by a put to redefine
3686         attributes of a property, clearly this is less efficient than it could be
3687         but we can improve this if it needs to be possible in future.

3843         "illegal operand" for m_attributesInPrevious in structure.ccp
3844         (when calling make_pair functions).
3845         This error is apparently due to the compiler not properly

3847

3923         [Qt] Fix wtf/ThreadSpecific.h under Qt to free thread local objects.
3924         https://bugs.webkit.org/show_bug.cgi?id=29295
3925
3926         This is an important fix when JavaScript workers are in use, since
3927         unfreed ThreadGlobalDatas leak a big amount of memory (50-100k each).
3928         QThreadStorage calls the destructor of a given object, which is the
3929         ThreadSpecific::Data. Unlike pthread, Qt is object oriented, and does
3930         not support the calling of a static utility function when the thread
3931         is about to close. In this patch we call the ThreadSpecific::destroy()
3932         utility function from the destructor of ThreadSpecific::Data. Moreover,
3933         since Qt resets all thread local values to 0 before the calling of the
3934         appropriate destructors, we set back the pointer to its original value.
3935         This is necessary because the get() method of the ThreadSpecific
3936         object may be called during the exuction of the destructor.

4085         produces the list of properties on an object excluding its prototype chain and getPropertyNames
4086         just iterates the the object and its prototype chain calling getOwnPropertyNames at each level.

4131         Add a flag to TypeInfo to indicate whether a type overrides getPropertyNames.
4132         This flag is used to make sure that caching of the property name data is safe.

4185         Compiling JavaScriptCore on sparc 64 with gcc fails.
4186
4187         ThreadSafeShared uses the atomic __gnu_cxx::__exchange_and_add with an int,
4188         however on sparc 64 the _Atomic_word argument is typedefed to long (8 bytes).
4189
4190         The patch disables WTF_USE_LOCKFREE_THREADSAFESHARED in ThreadSafeShared to use
4191         a mutex instead when compiling for sparc 64 with gcc.
