  64           make each distinct C++ class get a distinct JSC::Structure
  65
  66         * JavaScriptCore.exp: Exported constructEmptyObject for use in WebCore.
  67
  68         * kjs/JSGlobalObject.h: Changed the protected constructor to take a
  69         structure instead of a prototype.

  74
  75         Reviewed by Alexey Proskuryakov.
  76
  77         Use the template hoisting technique on the RefCounted class. This reduces the code bloat due to
  78         non-template methods' code been copied for each instance of the template.
  79         The patch splits RefCounted between a base class that holds non-template methods and attributes
  80         and the template RefCounted class that keeps the same functionnality.
  81
  82         On my Linux with gcc 4.3 for the Gtk port, this is:
  83         - a ~600KB save on libwebkit.so in release.
  84         - a ~1.6MB save on libwebkit.so in debug.
  85
  86         It is a wash on Sunspider and a small win on Dromaeo (not sure it is relevant).
  87         On the whole, it should be a small win as we reduce the compiled code size and the only
  88         new function call should be inlined by the compiler.
  89
  90         * wtf/RefCounted.h:
  91         (WTF::RefCountedBase::ref): Copied from RefCounted.
  92         (WTF::RefCountedBase::hasOneRef): Ditto.
  93         (WTF::RefCountedBase::refCount): Ditto.
  94         (WTF::RefCountedBase::RefCountedBase): Ditto.
  95         (WTF::RefCountedBase::~RefCountedBase): Ditto.
  96         (WTF::RefCountedBase::derefBase): Tweaked from the RefCounted version to remove
  97         template section.
  98         (WTF::RefCounted::RefCounted):
  99         (WTF::RefCounted::deref): Small wrapper around RefCountedBase::derefBase().
 100         (WTF::RefCounted::~RefCounted): Keep private destructor.

 107           make each distinct C++ class get a distinct JSC::Structure
 108
 109         * kjs/lookup.h: Removed things here that were used only in WebCore:

 111         and JSC_IMPLEMENT_PROTOTYPE.

 124         (JSC::Lexer::lex): Use makeIdentifier instead of makeUString for String.
 125         * kjs/lexer.h: Remove makeUString.
 126
 127         * kjs/nodes.h: Changed StringNode to hold an Identifier instead of UString.
 128
 129         * VM/CodeGenerator.cpp:
 130         (JSC::keyForCharacterSwitch): Updated since StringNode now holds an Identifier.
 131         (JSC::prepareJumpTableForStringSwitch): Ditto.
 132         * kjs/nodes.cpp:

 149         Bug 20911: REGRESSION(r36480?): Reproducible assertion failure below derefStructureIDs 64-bit JavaScriptCore
 150         <https://bugs.webkit.org/show_bug.cgi?id=20911>
 151
 152         The problem was simply caused by the int constructor for Instruction
 153         failing to initialise the full struct in 64bit builds.

 210         PCRE. This change was already made in WREC, and it fixes one of the
 211         Mozilla JS tests. Since it is now fixed in PCRE as well, we can check
 212         in a new set of expected test results.

 240         Bug 20876: REGRESSION (r36417, r36427): fast/js/exception-expression-offset.html fails
 241         <https://bugs.webkit.org/show_bug.cgi?id=20876>
 242
 243         r36417 and r36427 caused an get_by_id opcode to be emitted before the
 244         instanceof and construct opcodes, in order to enable inline caching of
 245         the prototype property. Unfortunately, this regressed some tests dealing
 246         with exceptions thrown by 'instanceof' and the 'new' operator. We fix
 247         these problems by detecting whether an "is not an object" exception is
 248         thrown before op_instanceof or op_construct, and emit the proper
 249         exception in those cases.

 282
 283         Improve timer accuracy for JavaScript Date object on Windows.
 284
 285         Use a combination of ftime and QueryPerformanceCounter.
 286         ftime returns the information we want, but doesn't have sufficient resolution.
 287         QueryPerformanceCounter has high resolution, but is only usable to measure time intervals.
 288         To combine them, we call ftime and QueryPerformanceCounter initially. Later calls will use
 289         QueryPerformanceCounter by itself, adding the delta to the saved ftime.  We re-sync to
 290         correct for drift if the low-res and high-res elapsed time between calls differs by more
 291         than twice the low-resolution timer resolution.
 292
 293         QueryPerformanceCounter may be inaccurate due to a problems with:
 294         - some PCI bridge chipsets (http://support.microsoft.com/kb/274323)
 295         - BIOS bugs (http://support.microsoft.com/kb/895980/)

 356         Fix a problem stemming from the slightly unsafe behaviour of the

 724         deisplacements, and branch offsets.

 727         instruction's immediate operant is updateded, and a memory access operation's
 728         displacement is updated to access the correct field on the object.  In the case
 729         of more complex accesses (array length and get_by_id_prototype) the offset on
 730         the branch to slow-case is updated, to now jump to a trampoline.

1198         1.012x speedup on SunSpider.
1199
1200         We create special structure IDs for JSString and
1201         JSNumberCell. Unlike normal structure IDs, these cannot hold the
1202         true prototype. Due to JS autoboxing semantics, the prototype used
1203         when looking up string or number properties depends on the lexical
1204         global object of the call site, not the creation site. Thus we
1205         enable StructureIDs to handle this quirk for primitives.

1694         Split storage of properties out of the PropertyMap and into the JSObject

1697         transition based on property name and attribute pairs, instead of just

2441
2442         Jump through the necessary hoops required to make MSVC cooperate with SFX
2443
2444         We now explicitly declare the calling convention on all cti_op_* cfunctions,
2445         and return int instead of bool where appropriate (despite the cdecl calling
2446         convention seems to state MSVC generates code that returns the result value
2447         through ecx).  SFX behaves slightly differently under MSVC, specifically it
2448         stores the base argument address for the cti_op_* functions in the first
2449         argument, and then does the required stack manipulation through that pointer.
2450         This is necessary as MSVC's optimisations assume they have complete control
2451         of the stack, and periodically elide our stack manipulations, or move
2452         values in unexpected ways.  MSVC also frequently produces tail calls which may
2453         clobber the first argument, so the MSVC path is slightly less efficient due
2454         to the need to restore it.

3064
3065         Zero-cost exception handling.  This patch takes the exception checking
3066         back of the hot path.  When an exception occurs in a Machine::cti*
3067         method, the return address to JIT code is recorded, and is then
3068         overwritten with a pointer to a trampoline routine.  When the method
3069         returns the trampoline will cause the cti_vm_throw method to be invoked.
3070
3071         cti_vm_throw uses the return address preserved above, to discover the
3072         vPC of the bytecode that raised the exception (using a map build during
3073         translation).  From the VPC of the faulting bytecode the vPC of a catch
3074         routine may be discovered (unwinding the stack where necesary), and then
3075         a bytecode address for the catch routine is looked up.  Final cti_vm_throw
3076         overwrites its return address to JIT code again, to trampoline directly
3077         to the catch routine.
3078
3079         cti_op_throw is handled in a similar fashion.

3602         Fix fast/js/bitwise-and-on-undefined.html.
3603
3604         A temporary value in the slow path of op_bitand was being stored in edx, but was
3605         being clobbered by emitGetPutArg before we used it.  To fix this, emitGetPutArg
3606         now takes a third argument that specifies the scratch register to use when loading
3607         from memory.  This allows us to avoid clobbering the temporary in op_bitand.
