Revision 35651, despite being a rather trivial change, introduced a
large regression on the regexp-dna SunSpider test. This regression
stemmed from an increase in the size of CodeBlock::dump(). There is
no reason for this method (and several related methods) to be compiled
in non-debug builds with the sampling tool disabled. This patch
conditionally compiles them, reversing the regression on SunSpider.

Improve performance of arithmetic operators
Added a fast (non-virtual) mechanism to determine if a non-immediate JSValue*
is a JSNumberCell. We then use this to allow improved specialisation in many
arithmetic operators. SunSpider reports a 2.5% progression overall, with greater
than 10% progressions on a number of arithmetic heavy tests.

Bug 19359: JavaScriptCore behaves differently from FF2/3 and IE when handling context in catch statement
<https://bugs.webkit.org/show_bug.cgi?id=19359>
Make our catch behave like Firefox and IE, we do this by using a StaticScopeObject
instead of a generic JSObject for the scope node. We still don't make use of the
fact that we have a static scope inside the catch block, so the internal performance
of the catch block is not improved, even though technically it would be possible to
do so.

wx build fix for Win.
On wx/Win, including windows.h in Threading.h causes multiply-defined symbol errors
for libjpeg and wx, and also wx needs to include windows.h itself first for wx
includes to work right. So until we can find a better solution to this problem,
on wx, we work around the need to include windows.h here.

Fix the build system for the Qt port.
Recent JavaScriptCore changes require the addition of JavaScriptCore/API to the
include search path. With a build process that combines JavaScriptCore and
WebCore in one build process/Makefile the existance of
JavaScriptCore/API/Node.h and WebCore/dom/Node.h causes include conflicts.
This commit solves this by introducing a separate build of JavaScriptCore into
a static library.
As a result of the split-up a race-condition due to broken dependencies of
regular source files to header files of generated sources showed up very
frequently when doing parallel builds (which the buildbot does). This commit at
the same time tries to address the dependency problem by making the
addExtraCompiler() function also generate a pseudo extra compiler that
represents the header file output, so that qmake is aware of the creation of
the header file for dependency calculation.
At the same time I removed a lot of cruft from the pro files to ease maintenance.

This means a few things:
1. Register::jsValue() clients, including ArgList clients, must now supply
an ExecState* when accessing an entry in an ArgList, in case the entry
will need to create a JSValue* on the fly.
2. Register clients that definitely don't want to create a JSValue* on
the fly now use different APIs: getJSValue() for clients that know
the register contains a JSValue*, and v() for clients who just want a
void*.
3. I had to change some headers around in order to resolve dependency

First step toward putting doubles in registers: Turned Register into a
proper abstraction layer. It is no longer possible to cast a Register
to a JSValue*, or a Register& to a JSValue*&, or to access the union
inside a Register directly.
SunSpider reports no change.
In support of this change, I had to make the following mechanical changes
in a lot of places:
1. Clients now use explicit accessors to read data out of Registers, and
implicit copy constructors to write data into registers.
So, assignment that used to look like
x.u.jsValue = y;
now looks like
x = y;
And access that used to look like
x = y.u.jsValue;
now looks like
x = y.jsValue();
2. I made generic flow control specific in opcodes that made their flow
control generic by treating a Register& as a JSValue*&. This had the
added benefit of removing some exception checking branches from immediate
number code.
3. I beefed up PropertySlot to support storing a Register* in a property
slot. For now, only JSVariableObject's symbolTableGet and symbolTablePut
use this functionality, but I expect more clients to use it in the future.
4. I changed ArgList to be a buffer of Registers, not JSValue*'s, and I
changed ArgList iterator clients to iterate Registers, not JSValue*'s.

a result that it didn't deliver. Also, it helped by labeling JSC heap regions as reported by

way to label mapped regions is to use a VM tag.

REGRESSION (r34907): Gmail crashes in JavaScriptCore code while editing drafts
I was never able to reproduce this issue, but Cameron could, and he says
that this patch fixes it.
The crash seems tied to a timer or event handler callback. In such a case,
the sole reference to the global object may be in the current call frame,
so we can't depend on the global object to mark the call frame area in
the register file.
The new GC marking rule is: the global object is not responsible for
marking the whole register file -- it's just responsible for the globals
section it's tied to. The heap is responsible for marking the call frame area.

Bug 18626: SQUIRRELFISH: support the "slow script" dialog <https://bugs.webkit.org/show_bug.cgi?id=18626>
<rdar://problem/5973931> Slow script dialog needs to be reimplemented for squirrelfish
Adds support for the slow script dialog in squirrelfish. This requires the addition
of three new op codes, op_loop, op_loop_if_true, and op_loop_if_less which have the
same behaviour as their simple jump equivalents but have an additional time out check.
Additional assertions were added to other jump instructions to prevent accidentally
creating loops with jump types that do not support time out checks.
Sunspider does not report a regression, however this appears very sensitive to code
layout and hardware, so i would expect up to a 1% regression on other systems.
Part of this required moving the old timeout logic from JSGlobalObject and into Machine
which is the cause of a number of the larger diff blocks.

One RegisterFile to rule them all!
SunSpider reports a 0.2% speedup.
This patch removes the RegisterFileStack abstraction and replaces it with
a single register file that
(a) allocates a fixed storage area, including a fixed area for global
vars, so that no operation may cause the register file to reallocate
and
(b) swaps between global storage areas when executing code in different
global objects.
This patch also changes the layout of the register file so that all call
frames, including call frames for global code, get a header. This is
required to support re-entrant global code. It also just makes things simpler.
* VM/CodeGenerator.cpp:
(KJS::CodeGenerator::addGlobalVar): New function. Differs from addVar in
that
(a) global vars don't contribute to a CodeBlock's numLocals count, since
global storage is fixed and allocated at startup
and
(b) references to global vars get shifted to elide intermediate stack
between "r" and the global storage area.
* VM/Machine.cpp:
(KJS::Machine::dumpRegisters): Updated this function to match the new
register file layout, and added the ability to dump exact identifiers
for the different parts of a call frame.
(KJS::Machine::unwindCallFrame): Updated this function to match the new
register file layout.
(KJS::Machine::execute): Updated this function to initialize a call frame
header for global code, and to swap global storage areas when switching
to execution in a new global object.
(KJS::Machine::privateExecute): Got rid of "safeForReentry" and re-reading
of registerBase because the register file is always safe for reentry now,
and registerBase never changes.
* VM/Machine.h: Moved the call frame header enum from Machine to RegisterFile,
to resolve a header dependency problem (a good sign that the enum belonged
in RegisterFile all along!)
* VM/RegisterFile.cpp:
* VM/RegisterFile.h: Changed RegisterFile to mmap a fixed size register
area. This allows us to avoid re-allocting the register file later on.
Instead, we rely on the OS to allocate physical pages to the register
file as necessary.
* VM/RegisterFileStack.cpp: Removed. Tada!
* VM/RegisterFileStack.h: Removed. Tada!
* kjs/DebuggerCallFrame.cpp: Updated this class to match the new

- work toward https://bugs.webkit.org/show_bug.cgi?id=19721
More preparation toward making functions work on primitive types without
creating wrapper objects. No speedup this time, but prepares for a future
speedup without slowing things down.
SunSpider reports no change.
- Eliminated the implementsCall, callAsFunction and construct virtual
functions from JSObject. Instead, the CallData and ConstructData for
a native function includes a function pointer that the caller can use
directly. Changed all call sites to use CallData and ConstructData.
- Changed the "this" argument to native functions to be a JSValue rather
than a JSObject. This prepares us for passing primitives into these
functions. The conversion to an object now must be done inside the
function. Critically, if it's a function that can be called on a DOM
window object, then we have to be sure to call toThisObject on the
argument before we use it for anything even if it's already an object.
- Eliminated the practice of using constructor objects in the global
object to make objects of the various basic types. Since these
constructors can't be replaced by script, there's no reason to involve
a constructor object at all. Added functions to do the construction
directly.
- Made some more class members private and protected, including virtual
function overrides. This can catch code using unnecessarily slow virtual
function code paths when the type of an object is known statically. If we
later find a new reason use the members outside the class it's easy to
make them public again.
- Moved the declarations of the native implementations for functions out
of header files. These can have internal linkage and be declared inside
the source file.
- Changed PrototypeFunction to take function pointers with the right
arguments to be put directly into CallData. This eliminates the
need to have a separate PrototypeReflexiveFunction, and reveals that the
real purpose of that class included something else specific to eval --
storage of a cached global object. So renamed PrototypeReflexiveFunction
to GlobalEvalFunction.

* JavaScriptCore.exp:
* VM/Machine.cpp: We need to let the profiler know when the JS program

(KJS::Profile::Profile): We now have a client, which is a listener who
we will return this profile to, once it has actually finished.
(KJS::Profile::stopProfiling): Instead of fully stopping the profiler
here, we set the flag and keep it profiling in the background.
(KJS::Profile::didFinishAllExecution): This is where the profiler
actually finishes and creates the (idle) node if one should be made.
(KJS::Profile::removeProfileStart): Don't use m_currentNode since it is
needed by the profiler as it runs silently in the background.
(KJS::Profile::removeProfileEnd): Ditto.

Bug 19596: LEAK: Gmail leaks SegmentedVector<RegisterID>
<https://bugs.webkit.org/show_bug.cgi?id=19596>
When growing SegmentedVector, we start adding segments at the position
of the last segment, overwriting it. The destructor frees allocated
segments starting at the segment of index 1, because the segment of
index 0 is assumed to be the initial inline segment. This causes a leak
of the segment that is referenced by index 0. Modifying grow() so that
it starts adding segments at the position after the last segment fixes
the leak.
Since the initial segment is a special case in the lookup code, this
bug never manifested itself via incorrect results.

Slight cleanup to the SymbolTableEntry class.
Renamed isEmpty to isNull, since we usually use "empty" to mean "holds
the valid, empty value", and "null" to mean "holds no value".
Changed an "== 0" to a "!", to match our style guidelines.
Added some ASSERTs to verify the (possibly questionable) assumption that
all register indexes will have their high two bits set. Also clarified a
comment to make that assumption clear.

Bug 19484: More instructions needs to use temporary registers
<https://bugs.webkit.org/show_bug.cgi?id=19484>
Fix codegen for all binary operations so that temporaries are used if
necessary. This was done by making BinaryOpNode and ReverseBinaryOpNode
subclasses of ExpressionNode, and eliminating the custom emitCode()
methods for the individual node classes.
This only adds 3 new instructions to SunSpider code, and there is no
difference in SunSpider execution time.

speed up SunSpider by eliminating the toObject call for most get/put/delete
Makes standalone SunSpider 1.025x as fast as before.
The getOwnPropertySlot virtual function now takes care of the toObject call
for get. Similarly, the put function (and later deleteProperty) does the
same for those operations. To do this, the virtual functions were moved from
the JSObject class to the JSCell class. Also, since the caller no longer knows
the identity of the "original object", which is used by JavaScript-function
based getters, changed the PropertySlot class so the original object is
already stored in the slot when getOwnPropertySlot is called, if the caller
intends to call getValue.
This affected the old interpreter code enough that the easiest thing for me
was to just delete it. While I am not certain the mysterious slowdown is not
still occurring, the net change is definitely a significant speedup.
* JavaScriptCore.exp: Updated.
* VM/Machine.cpp: Moved the UNLIKELY macro into AlwaysInline.h.
(KJS::resolve): Set up the originalObject in the PropertySlot before
calling getPropertySlot. Also removed the originalObject argument from
getValue.
(KJS::resolve_skip): Ditto.
(KJS::resolveBaseAndProperty): Ditto.
(KJS::resolveBaseAndFunc): Ditto.
(KJS::Machine::privateExecute): Removed the toObject calls from the get and
put functions where possible, instead calling directly with JSValue and letting
the JSValue and JSCell calls handle toObject. Same for toThisObject.
* kjs/ExecState.h: Removed OldInterpreterExecState.
* API/JSBase.cpp: Updated includes.
* kjs/LocalStorageEntry.h: Removed contents. Later we can remove the file too.
* kjs/array_instance.cpp:
(KJS::ArrayInstance::lengthGetter): Removed originalObject argumet.
(KJS::ArrayInstance::inlineGetOwnPropertySlot): Don't pass a base value to
setValueSlot. Also use UNLIKELY around the "getting elements past the end of
the array" code path; less common than successfully getting an element.
* kjs/array_object.cpp:
(KJS::getProperty): Initialize the PropertySlot with the original object.
Don't pass the original object to the get function.
(KJS::arrayProtoFuncFilter): Ditto.
(KJS::arrayProtoFuncMap): Ditto.
(KJS::arrayProtoFuncEvery): Ditto.
(KJS::arrayProtoFuncForEach): Ditto.
(KJS::arrayProtoFuncSome): Ditto.
* kjs/function_object.cpp:

(KJS::GetterSetterImp::getOwnPropertySlot): Added. Not reached.
(KJS::GetterSetterImp::put): Ditto.
(KJS::GetterSetterImp::toThisObject): Ditto.
* kjs/internal.h: Added toThisObject to NumberImp for speed.
* kjs/lexer.cpp:

the loop and especially to make the one character case faster.
(KJS::Lexer::setCode): Call shift multiple times instead of passing a number.

* kjs/lexer.h: Removed the count argument from shift.
* kjs/math_object.cpp:

* kjs/nodes.cpp: Removed some of the things needed only for the pre-SquirrelFish
execution model.
(KJS::ForNode::emitCode): Handle cases where some expressions are missing by
not emitting any code at all. The old way was to emit code for "true", but
this is an unnecessary remnant of the old way of doing things.
* kjs/nodes.h: Removed some of the things needed only for the pre-SquirrelFish
execution model.
* kjs/object.cpp:
(KJS::JSObject::fillGetterPropertySlot): Changed to only pass in the getter
function. The old code passed in a base, but it was never used when
actually getting the property; the toThisObject call was pointless. Also
changed to not pass a base for setUndefined.
* kjs/object.h: Added the new JSCell operations to GetterSetterImp.
Never called.
(KJS::JSObject::get): Initialize the object in the PropertySlot and don't
pass it in getValue.
(KJS::JSObject::getOwnPropertySlotForWrite): Removed the base argument
in calls to setValueSlot.
(KJS::JSObject::getOwnPropertySlot): Ditto.
(KJS::JSValue::get): Added. Here because it calls through to JSObject.
A version of JSObject::get that also handles the other types of JSValue
by creating the appropriate wrapper. Saves the virtual call to toObject.
(KJS::JSValue::put): Ditto.
(KJS::JSValue::deleteProperty): Ditto.
* kjs/property_slot.cpp:
(KJS::PropertySlot::undefinedGetter): Removed the originalObject argument.
(KJS::PropertySlot::ungettableGetter): Ditto.
(KJS::PropertySlot::functionGetter): Ditto. Use the value in the base
as the "this" object, which will be set to the original object by the new
PropertySlot initialization code. Also call toThisObject. The old code did
not do this, but needed to so we can properly handle the activation object
like the other similar code paths.
* kjs/property_slot.h:
(KJS::PropertySlot::PropertySlot): Added a constructor that takes a base
object. In debug builds, set the base to 0 if you don't pass one.
(KJS::PropertySlot::getValue): Don't take or pass the originalObject.
(KJS::PropertySlot::setValueSlot): Don't take a base object, and clear the
base object in debug builds.
(KJS::PropertySlot::setGetterSlot): Ditto.
(KJS::PropertySlot::setUndefined): Ditto.
(KJS::PropertySlot::setUngettable): Ditto.
(KJS::PropertySlot::slotBase): Assert that a base object is present.
This will fire if someone actually calls the get function without having
passed in a base object and the getter needs it.
(KJS::PropertySlot::setBase): Added. Used by the code that implements
toObject so it can supply the original object after the fact.
(KJS::PropertySlot::clearBase): Added. Clears the base, but is debug-only
code because it's an error to fetch the base if you don't have a guarantee
it was set.

the various PropertySlot functions that no longer take them.
* kjs/value.cpp:
(KJS::JSCell::getOwnPropertySlot): Added. Calls toObject and then sets the slot.
This function has to always return true, because the caller can't walk the prototype
chain. Because of that, we do a getPropertySlot, not getOwnPropertySlot, which works
for the caller. This is private, only called by getOwnPropertySlotInternal.
(KJS::JSCell::put): Added. Calls toObject and then put.
(KJS::JSCell::toThisObject): Added. Calls toObject.
* kjs/value.h: Added get, put, and toThisObject to both JSValue
and JSCell. These take care of the toObject operation without an additional virtual
function call, and so make the common "already an object" case faster.

<rdar://problem/5950867> JSProfiler: Allow the profiler to "Focus" a
profile node.
- This patch updatest the times of the visible nodes correctly, but to do
so, some of the design of the ProfileNode changed.
* JavaScriptCore.exp: export focus' symbol.
* profiler/Profile.cpp: ProfileNodes now take a reference to the head of
the profile tree to get up-to-date accurate total profile time.
(KJS::Profile::Profile): Pass 0 for the head node.
(KJS::Profile::stopProfiling): stopProfiling no longer needs the time
passed into it, since it can get it from the head and it does not need to
be told it is the head because it can figure it out on it's own.
(KJS::Profile::willExecute): Set the head node for each created node.
* profiler/Profile.h:
(KJS::Profile::focus): Instead of taking a CallIdentifier that the caller
would have to create, now focus() takes a ProfileNode that they should
already have a reference to and focus() can extract the CallIdentifier
from it.
* profiler/ProfileNode.cpp: Create actual and visible versions fo the
total and self times for focus and exclude. Also add a head node
reference so that nodes can get information from their head.
(KJS::ProfileNode::ProfileNode):
(KJS::ProfileNode::stopProfiling): Rename the total and self time
variables and set the visual ones to the actual ones, so that without any
changes to the visual versions of these variables, their times will match
the actual times.
(KJS::ProfileNode::focus): Now focus() has a bool to force it's children
to be visible if this node is visible. If this node does not match the
CallIdentifier being focused then the visibleTotalTime is only updated if
one or more of it's children is the CallIdentifier being focused.
(KJS::ProfileNode::restoreAll): Restores all variables with respect to
the visible data in the ProfileNode.
(KJS::ProfileNode::endAndRecordCall): Name change.

emitThrowError needs to return the temporary holding the error, not dst,
since dst may be NULL. In fact, emitThrowError shouldn't take a dst
parameter at all, since exceptions should not modify the destination
register.

Replace old attempt at "branchless" exceptions as the extra information

Fixed scopes for named function expressions.
Fixes one regression test.
Two changes here:
(1) The function's name is supposed to have attributes DontDelete,
ReadOnly, regardless of the type of code executing.
(2) Push the name object on the function's scope chain, rather than
the ExecState's scope chain because, well, that's where it belongs.

Inlined JSObject::putDirect, for a .4% SunSpider speedup.
I did this as a first step toward removing nodes.cpp from
AllInOneFile.cpp, but I'm putting that larger project aside for now.

- add OldInterpreterExecState class and use it in dead code
This will allow removing things from the real ExecState class
without having to figure out how to remove all this code without
getting a perf regression.

A little refactoring in preparation for supporting 'arguments'.
Fixes 2 regression tests.
SunSpider reports no change.
We now check the activation register, instead of the codeBlock, to
determine whether we need to tear off the activation. This is to support
"f.arguments", which will create an activation/arguments pair for f,
even though the needsFullScopeChain flag is false for f's codeBlock.
The test fixes resulted from calling initializeCallFrame for re-entrant
function code, instead of initializing (not enough) parts of the call
frame by hand.

Fixed ScopeChainNode lifetime problems:
(1) In "with" and "catch" scopes, we would construct a ScopeChain
object and then jump across its destructor, leaking the ScopeChainNode
we had pushed.
(2) In global and eval scopes, we would fail to initially ref
"scopeChain", causing us to overrelease it later. Now that we ref
"scopeChain" properly, we also need to deref it when the script
terminates.
SunSpider reports a .2% regression, but an earlier round of ScopeChain
refactoring was a .4% speedup, so there.

Bug 18619: Support continue, break, and return in try .. finally blocks
<https://bugs.webkit.org/show_bug.cgi?id=18619>
This patch replaces the current partial finally support (which uses code
duplication to achieve what it does) with a subroutine based approach.
This has a number of advantages over code duplication:
* Reduced code size
* Simplified exception handling as the finaliser code only exists in
one place, so no "magic" is needed to get the correct handler for a
finaliser.
* When we support instruction to line number mapping we won't need to
worry about the dramatic code movement caused by duplication
On the downside it is necessary to add two new opcodes, op_jsr and op_sret
to enter and exit the finaliser subroutines, happily SunSpider reports
a performance progression (gcc amazes me) and ubench reports a wash.
While jsr and sret provide a mechanism that allows us to enter and exit
any arbitrary finaliser we need to, it was still necessary to increase
the amount of information tracked when entering and exiting both finaliser
scopes and dynamic scopes ("with"). This means "scopeDepth" is now
the combination of "finaliserDepth" and "dynamicScopeDepth". We also
now use a scopeContextStack to ensure that we pop scopes and execute
finalisers in the correct order. This increases the cost of "with" nodes
during codegen, but it should not be significant enough to effect real
world performance and greatly simplifies codegen for return, break and
continue when interacting with finalisers.

- fix codegen handling of dst registers
1.006x speedup (not sure why).
Most emitCode functions take an optional "dst" parameter that says
where the output of the instruction should be written. I made some
functions for convenient handling of the dst register:
* VM/CodeGenerator.h:
(KJS::CodeGenerator::tempDestination): Takes the dst register. Returns it if
it is not null and is a temporary, otherwise allocates a new temporary. This is
intended for cases where an intermediate value might be written into the dst
(KJS::CodeGenerator::finalDestination): Takes the dst register and an optional
register that was used as a temp destination. Picks the right thing for the final
output. Intended to be used as the output register for the instruction that generates
the final value of a particular node.
(KJS::CodeGenerator::moveToDestinationIfNeeded): Takes dst and a
RegisterID; moves from the register to dst if dst is defined and
different from the register. This is intended for cases where the
result of a node is already in a specific register (likely a
local), and so no code needs to be generated unless a specific
destination has been requested, in which case a move is needed.
I also applied these methods throughout emitCode functions. In
some cases this was just cleanup, in other cases I fixed actual
codegen bugs. Below I have given specific comments for the cases
where I believe I fixed a codegen bug, or improved quality of codegen.

Fix two bugs when throwing exceptions from re-entrant JS calls:
(1) Don't shrink the register file to 0, since our caller may still
be using it.
(2) In case of exception, return jsNull() instead of 0 because,
surprisingly, some JavaScriptCore clients rely on a function's return
value being safe to operate on even if the function threw an exception.
Also:
- Changed FunctionImp::callAsFunction to honor the new semantics of
exceptions not returning 0.
- Renamed "handlerPC" to "handlerVPC" to match other uses of "VPC".
- Renamed "exceptionData" to "exceptionValue", because "data" seemed to
imply something more than just a JSValue.
- Merged prepareException into throwException, since throwException was
its only caller, and it seemed weird that throwException didn't take
an exception as an argument.

Re-entrant execution of function code (global code -> built-in function

Miraculously, sunspider --squirrelfish does not seem to complain.
A re-entrant function call is the same as a normal function call with
one exception: the re-entrant call leaves everything except for
CallerCodeBlock in the call frame header uninitialized, since the call
doesn't need to return to JS code. (It sets CallerCodeBlock to 0, to
indicate that the call shouldn't return to JS code.)
Also fixed a few issues along the way:
- Fixed two bugs in the read-write List implementation that caused
m_size and m_buffer to go stale.
- Changed native call code to update "r" *before* setting the return
value, since the call may in turn call JS code, which changes the value
of "r".
- Migrated initialization of "r" outside of Machine::privateExecute,
because global code and function code initialize "r" differently.
- Migrated a codegen warning from Machine::privateExecute to the wiki.

First step toward supporting re-entrant evaluation: Switch register
clients from using "registers", a pointer to a register vector, to
"registerBase", an indirect pointer to the logical first entry in the
register file. (The logical first entry is the first entry that is not
a global variable).
With a vector, offsets into the register file remain good when the
underlying buffer reallocates, but they go bad when the logical
first entry moves. (The logical first entry moves when new global
variables get added to the beginning of the register file.) With an
indirect pointer to the logical first entry, offsets will remain good
regardless.
1.4% speedup on sunspider --squirrelfish. I suspect this is due to
reduced allocation when creating closures, and reduced indirection
through the register vector.

more of a "nice to have": it makes register layout in the case of
collisions easier to understand, and has the added benefit of saving
memory.
(3) Allocate slots in the CodeGenerator's m_locals vector in parallel
to register indexes in the symbol table. This ensures that, given an
index in the symbol table, we can find the corresponding RegisterID
without hashing, which speeds up codegen.
I moved responsibility for emitting var and function initialization
instructions into the CodeGenerator, because bookkeeping in cases where
var, function, and/or parameter names collide requires a lot of
internal knowledge about the CodeGenerator.
* VM/CodeGenerator.cpp:
(KJS::CodeGenerator::addVar): Removed responsibility for checking whether
a var declaration overwrites "arguments", because the check is
inappropriate for global code, which may not have a pre-existing
"arguments" symbol in scope. Also changed this function to return a
boolean indicating whether addVar actually created a new RegisterID,
or just reused an old one.
(KJS::CodeGenerator::CodeGenerator): Split out the constructors for
function code and global code, since they're quite different now.
(KJS::CodeGenerator::registerForLocal): This function does its job
without any hashing now.
* VM/Machine.cpp: Move old globals and update "r" before executing a
new script. That way, old globals stay at a constant offset from "r",
and previously optimized code still works.
* VM/RegisterID.h: Added the ability to allocate a RegisterID before
initializing its index field. We use this for parameters now.
* kjs/JSVariableObject.h:
(KJS::JSVariableObject::symbolTableGet): Changed the ungettable getter

Implemented native function calls. (Re-entering from native code back
to JS doesn't work yet, though.)
0.2% speedup overall, due to some inlining tweaks. 3.6% regression on
function-empty.js, since we're making a new virtual call and taking a
new branch inside every op_call.
I adjusted the JavaScriptCore calling convention to minimize overhead,
like so:
The machine calls a single virtual function, "getCallData", to get all
the data it needs for a function call. Native code still uses the old
"isObject()" check followed by an "implementsCall()" check, which
aliases to "getCallData". (We can optimize native code to use getCallData
at our leisure.)
To supply a list of arguments, the machine calls a new List constructor
that just takes a pointer and a length, without copying. Native code
still appends to the list one argument at a time. (We can optimize
native code to use the new List constructor at our leisure.)
* VM/Machine.cpp:
(KJS::Machine::privateExecute): Changed resize() call to grow() call,

Change the Profiler to allow multiple profiles to be running at
the same time. This can happen when you have nested console.profile()
calls. This required two changes. First, the Profiler needed to keep a
Vector of current profiles, instead of one. Second, a Profile needs
to keep track of the global ExecState it started in and the page group
identifier it is tracking.
The stopProfiling call now takes the same arguments as startProfiling.
This makes sure the correct profile is stopped. Passing a null UString
as the title will stop the last profile for the matching ExecState.

- Cache some values to save on computing them repetitively. This will be
a big savings when we sort since we won't have to walk the tree for
every comparison!
- We cache these values when we end profiling because otherwise we won't
know which profile to get the totalTime for the whole profile from without
retaining a reference to the head profile or looking up the profile from
the list of all profiles.
- Also it's safe to assume we won't be asked for these values while we
are still profiling since the WebInspector only get's profileNodes from
profiles that are in the allProfiles() list and a profile is only added
to that list after it has finished and these values will no longer
change.

(KJS::Heap::markListSet): Moved from a static variable in List.cpp to a per-thread one here.
(KJS::Heap::heap): Added a method to find which heap a JSValue is allocated in.
* kjs/collector.cpp: Changed "const size_t" constants to #defines, to avoid a PIC branch
(gcc was using one to access a constant used in std::max(), because it takes a reference,
even though std::max() itself was inlined).
(KJS::Heap::threadHeap): JS heap is now per-thread.
(KJS::Heap::Heap): Zero-initialize the heap.
(KJS::allocateBlock): Added NEVER_INLINE, because this function uses a PIC branch, so
inlining it in Heap::heapAllocate() is bad for performance, now that the latter doesn't

- fix <rdar://problem/5657459> REGRESSION: JavaScriptCore no longer builds with
GCC 4.2 due to pointer aliasing warnings
Fix this by removing the HashTable optimizations that allowed us to share a back end
implementation between hash tables with integers, pointers, RefPtr, and String objects
as keys. The way it worked was incompatible with strict aliasing.
This increases code size. On Mac OS X we'll have to regenerate .order files to avoid
slowing down Safari startup times.
This creates a slight slowdown in SunSpider, mitigated by the following four speedups:
- speed up array put slightly by moving a branch (was already done for get)
- speed up symbol table access by adding a function named inlineGet to HashMap
and using that in symbolTableGet/Put
- speed up PropertyNameArray creation by reducing the amount of reference count
churn and uniqueness checking when adding names and not doing any allocation at
all when building small arrays
- speed up conversion of strings to floating point numbers by eliminating the
malloc/free of the buffer for the ASCII copy of the string; a way to make
things even faster would be to change strtod to take a UTF-16 string
Note that there is considerable unused complexity now in HashSet/Map/Table to support
"storage types", which is no longer used. Will do in a separate patch.
* API/JSCallbackObjectFunctions.h:
(KJS::JSCallbackObject<Base>::getPropertyNames): Removed explicit cast to Identifier to
take advantage of the new PropertyNameArray::add overload and avoid reference count churn.
* API/JSObjectRef.cpp:
(JSPropertyNameAccumulatorAddName): Ditto.
* JavaScriptCore.exp: Updated PropertyNameArray::add entry point name.
* kjs/JSVariableObject.cpp: Removed now-unneeded IdentifierRepHashTraits::nullRepPtr
definition (see below).
(KJS::JSVariableObject::getPropertyNames): Removed explicit cast to Identifier.
* kjs/JSVariableObject.h:
(KJS::JSVariableObject::symbolTableGet): Use inlineGet for speed. Also changed to do
early exit instead of nesting the body inside an if.
(KJS::JSVariableObject::symbolTablePut): Ditto.
* kjs/PropertyNameArray.cpp:
(KJS::PropertyNameArray::add): Changed implementation to take a raw pointer instead of
a reference to an identifier. Do uniqueness checking by searching the vector when the
vector is short, only building the set once the vector is large enough.
* kjs/PropertyNameArray.h: Added an overload of add for a raw pointer, and made the old
add function call that one. Added an addKnownUnique function for use when the new
name is known to be different from any other in the array. Changed the vector to have
an inline capacity of 20.
* kjs/SymbolTable.h: Changed IdentifierRepHash to inherit from the default hash for
a RefPtr so we don't have to define so much. Added an overload of the hash function for
a raw pointer as required by the new RefPtrHashMap. Got rid of the now-unneeded
IdentifierRepHashTraits -- the default traits now work fine. Added a definition of
empthValueIsZero to SymbolTableIndexHashTraits; not having it was incorrect, but harmless.
* kjs/array_instance.cpp:
(KJS::ArrayInstance::put): Move the maxArrayIndex check inside the branch that checks
the index against the length, as done in the get function.
* kjs/function.cpp:
(KJS::globalFuncKJSPrint): Changed to use the new getCString instead of cstring.
* kjs/internal.cpp: Removed printInfo debugging function, a client of cstring.
If we need a debugging function we can easily make a better one and we haven't
used this one in a long time.
* kjs/internal.h: Ditto.
* kjs/object.cpp:
(KJS::JSObject::getPropertyNames): Removed explicit cast to Identifier.
* kjs/property_map.cpp:
(KJS::PropertyMap::getEnumerablePropertyNames): Ditto. Also added a special case for
the case where the propertyNames array is empty -- in that case we know we're adding
a set of names that are non-overlapping so we can use addKnownUnique.
* kjs/ustring.cpp:
(KJS::UString::getCString): Replaces cstring. Puts the C string into a CStringBuffer,
which is a char Vector with an inline capacity. Also returns a boolean to indicate if
the converion was lossy, which eliminates the need for a separate is8Bit call.
(KJS::UString::toDouble): Changed to call getCString instead of cstring.
* kjs/ustring.h: Ditto.
* wtf/HashFunctions.h: Overload the hash and equal functions for RefPtr's default
hash to take raw pointers. This works with the changes to RefPtrHashMap to avoid
introducing refcount churn.
* wtf/HashMap.h: Removed special code to convert the deleted value to the empty value
when writing a new value into the map. This is now handled elsewhere.
(WTF::HashMap::get): Removed code that checks for an empty hash table before calling
HashTable::lookup; it's slightly more efficient to do this check inside lookup.
* wtf/HashTable.h:
(WTF::HashTable::isDeletedBucket): Changed to use isDeletedValue instead of using
deletedValue and the equality operator.
(WTF::HashTable::deleteBucket): Changed to use constructDeletedValue instead of
using deletedValue and the assignment operator.
(WTF::HashTable::checkKey): Added. Factors out the check for values that are empty
or deleted keys that's used in various functions below.
(WTF::HashTable::lookup): Changed to use checkKey, check for a 0 table, and also
made public for use by RefPtrHashMap.
(WTF::HashTable::lookupForWriting): Changed to use checkKey.
(WTF::HashTable::fullLookupForWriting): Changed to use checkKey.
(WTF::HashTable::add): Changed to use checkKey, and call initializeBucket on a
deleted bucket before putting a new entry into it.
(WTF::HashTable::addPassingHashCode): Ditto.
(WTF::HashTable::deallocateTable): Check isDeletedBucket before calling ~ValueType.
* wtf/HashTraits.h: Got ridd of all the HashTraits specialization for the integer
types, since GeneicHashTraitsBase already deals with integers separately. Put the
deleted value support into GenericHashTraitsBase. Changed FloatHashTraits to
inherit from GenericHashTraits, and define construct/isDeletedValue rather than
deletedValue. Removed the ref and deref functions from RefPtr's HashTraits, and
defined construct/isDeletedValue. Eliminated DeletedValueAssigner. Changed
PairHashTraits to define construct/isDeletedValue, and also merged
PairBaseHashTraits in with PairHashTraits. Got rid of all specialization of
HashKeyStorageTraits. We'll remove that, and the needsRef data member, later.
* wtf/RefPtr.h: Added HashTableDeletedValueType, an enum type with a single value,
HashTableDeletedValue. Used that type to make a new constructor to construct
deleted values and also added an isHashTableDeletedValue function.
* wtf/RefPtrHashMap.h: Added RefPtrHashMapRawKeyTranslator and used it to implement
the raw pointer functions. This is a way to continue to avoid refcount thrash. We
can't use the old way because it depended on the underlying map using a non-RefPtr
type.
(WTF::HashMap::find): Use find with RefPtrHashMapRawKeyTranslator.
(WTF::HashMap::contains): Use contains with RefPtrHashMapRawKeyTranslator.
(WTF::HashMap::inlineAdd): Use add with RefPtrHashMapRawKeyTranslator.
(WTF::HashMap::get): Removed code that checks for an empty hash table before calling
HashTable::lookup; it's slightly more efficient to do this check inside lookup.
(WTF::HashMap::inlineGet): Added. Just like get, but marked inline for use in the
symbol table code.

Fix https://bugs.webkit.org/show_bug.cgi?id=18367 and the many dupes.
Bug 18367: Crash during celtic kane js speed 2007 test
GCC 4.2 on x86_64 Linux decided to reorder the local variables in markCurrentThreadConservatively's
stack frame. This lead to the range of addresses the collector treated as stack to exclude the
contents of volatile registers that markCurrentThreadConservatively forces onto the stack. This was
leading to objects being prematurely collected if the only reference to them was via a register at
the time a collection occurred.
The fix for this is to move the calculation of the top of the stack into a NEVER_INLINE function
that is called from markCurrentThreadConservatively. This forces the dummy variable we use for
determining the top of stack to be in a different stack frame which prevents the compiler from
reordering it relative to the registers that markCurrentThreadConservatively forces onto the stack.

An assertion was failing in function-toString-object-literals.html when parsing 1e-500.
The condition existed before, and got uncovered by turning compiled-out dtoa checks into

Fixed <rdar://problem/5689093> Stricter (ES4) eval semantics
The basic rule is:
- "eval(s)" is treated as an operator that gives the ES3 eval behavior.
... but only if there is no overriding declaration of "eval" in scope.
- All other invocations treat eval as a function that evaluates a
script in the context of its "this" object.
... but if its "this" object is not the global object it was
originally associated with, eval throws an exception.
Because only expressions of the form "eval(s)" have access to local
scope, the compiler can now statically determine whether a function
needs local scope to be dynamic.
* kjs/nodes.h: Added FunctionCallEvalNode. It works just like
FuncationCallResolveNode, except it statically indicates that the node
may execute eval in the ES3 way.

Fix for <rdar://problem/5778247> - Reproducible crash on storage/execute-sql-args.html
DatabaseThread::unscheduleDatabaseTasks() manually filters through a MessageQueue,
removing particular items for Databases that were shutting down.
This filtering operation is not atomic, and therefore causes a race condition with the
MessageQueue waking up and reading from the message queue.
The end result was an attempt to dereference a null DatabaseTask. Timing-wise, this never
seemed to happen in a debug build, otherwise an assertion would've caught it. Replacing that
assertion with a crash in a release build is what revealed this bug.

Partial fix for <rdar://problem/5744037> Gmail out of memory (17455)
I'm removing KJS_MEM_LIMIT for the following reasons:
- We have a few reports of KJS_MEM_LIMIT breaking important web
applications, like GMail and Google Reader. (For example, if you
simply open 12 GMail tabs, tab #12 will hit the limit.)
- Firefox has no discernable JS object count limit, so any limit, even
a large one, is a potential compatibility problem.
- KJS_MEM_LIMIT does not protect against malicious memory allocation,
since there are many ways to maliciously allocate memory without
increasing the JS object count.
- KJS_MEM_LIMIT is already mostly broken, since it only aborts the
script that breaches the limit, not any subsequent scripts.
- We've never gotten bug reports about websites that would have
benefited from an unbroken KJS_MEM_LIMIT. The initial check-in of
KJS_MEM_LIMIT (KJS revision 80061) doesn't mention a website that
needed it.
- Any website that brings you anywhere close to crashing due to the
number of live JS objects will almost certainly put up the "slow
script" dialog at least 20 times beforehand.

PLT speedup related to <rdar://problem/5659272> REGRESSION: PLT .4%

Geoff's theory is that the slowdown was due to copying hash tables when
putting things into the back/forward cache. If that's true, then this

Incorrect Function.toString behaviour with read/modify/write operators performed on negative numbers
Test: fast/js/function-toString-parentheses.html
The problem here was that a NumberNode with a negative number in it had the wrong
precedence. It's not a primary expression, it's a unary operator with a primary
expression after it.
Once the precedence of NumberNode was fixed, the cases from bug 17020 were also
fixed without trying to treat bracket nodes like dot nodes. That wasn't needed.
The reason we handle numbers before dot nodes specially is that the dot is a
legal character in a number. The same is not true of a bracket. Eventually we
could get smarter, and only add the parentheses when there is actual ambiguity.
There is none if the string form of the number already has a dot in it, or if
it's a number with a alphabetic name like infinity or NAN.

types of ExecState. The primary goal here was to remove a branch from the
code in the destructor, but it's also clearer than overloading the arguments
to the ExecState constructor.

(KJS::getCurrentTime): Fixed formatting.
(KJS::JSGlobalObject::pushActivation): Removed parentheses that don't make

(KJS::JSGlobalObject::tearOffActivation): Got rid of unneeded static_cast
(I think I mentioned this during patch review) and used an early exit so that
the entire contents of the function aren't nested inside an if statement.
Also removed the check of codeType, instead checking Activation for 0.
For now, I kept the codeType check, but inside an assertion.

Reworked the JavaScriptCore Qt bindings:
* Add initial support for string and variant arrays, as well
as sub QObjects in the JS bindings.
* Don't expose fields marked as not scriptable by moc.
* Add support for dynamic properties and accessing named
QObject children of an object (like QtScript and older
IE DOM style JS).
* Add support for custom toString methods.
* Fine tune some bindings to be closer to QtScript.
Make void functions return undefined, and empty/
null QStrings return a zero length string.
* Create framework for allowing more direct method calls.
Since RuntimeMethod doesn't allow us to add additional
methods/properties to a function, add these classes.
Start prototyping object.signal.connect(...).
* Add signal support to the Qt bindings.
Allow connecting to signals (object.signal.connect(slot)),
disconnecting, and emitting signals. Currently chooses
the first signal that matches the name, so this will need
improvement.
* Add property names, and resolve signals closer to use.
Enumerating properties now returns some of the Qt properties
and signals. Slots and methods aren't quite present. Also,
resolve signal connections etc. closer to the time of use, so
we can do more dynamic resolution based on argument type etc.
Still picks the first one with the same name, at the moment.
* Make signature comparison code consistent.
Use the same code for checking meta signatures in
the method and fallback getters, and avoid a
QByteArray construction when we can.
* Fix minor memory leak, and handle pointers better.
Delete the private object in the dtors, and use RefPtrs
for holding Instances etc.
* Handle method lookup better.
Allow invocation time method lookup based on the arguments,
which is closer to QtScript behaviour. Also, cache the
method lists and delete them in the QtClass dtor (stops
a memory leak).
* Improve JS to Qt data type conversions.
Add some support for Date & RegExp JS objects,
and provide some metrics on the quality of the
conversion.
* A couple of fixes for autotest failures.
Better support for converting lists, read/write only
QMetaProperty support, modified slot search order...)

Fix <rdar://problem/5595552> r27608 introduced a 20% increase in JS binary size, 4% increase in WebCore binary size
- This changes the way JS functions that use Lookup tables are handled. Instead of using
one class per function, which allowed specialization of the virtual callAsFunction
method, we now use one class, PrototypeFunction, which takes a pointer to a static
function to use as the implementation. This significantly decreases the binary size
of JavaScriptCore (about 145k on an Intel only build) while still keeping some of the
speedup r27608 garnered (SunSpider says this is 1.005x as slow, which should leave some
wiggle room from the original 1% speedup) and keeps the functions implementations in separate
functions to help with optimizations.

To match Firefox, we've decided that var declarations will never shadow

speed up function calls by making ScopeChain::push cheaper
This gives a 1.019x speedup on SunSpider.
After doing this, I realized this probably will be obsolete when the optimization
to avoid creating an activation object is done. When we do that one we should check
if rolling this out will speed things up, since this does add overhead at the time
you copy the scope chain.

marked inline, and called in exactly one place, so moved it there.
No idea why it was in this header file!
* kjs/scope_chain.cpp: Removed the overload of the ScopeChain::push
function that takes another ScopeChain. It was unused. I think we used

a class, got rid of its constructor so we can have one that's uninitialized,
and moved the refCount into a derived struct, ScopeChainHeapNode. Made _node
mutable so it can be changed in the moveToHeap function. Changed the copy
constructor and assignment operator to call moveToHeap, since the top node
can't be shared when it's embedded in another ScopeChain object. Updated
functions as needed to handle the case where the first object isn't on the
heap or to add casts for cases where it's guaranteed to be. Changed the push
function to always put the new node into the ScopeChain object; it will get
put onto the heap when needed later.

AST optimization: Avoid NULL-checking ForNode's child nodes.
0.6% speedup on SunSpider.
This is a proof of concept patch that demonstrates how to optimize
grammar productions with optional components, like
for (optional; optional; optional) {
...
}
The parser emits NULL for an optional component that is not present.
Instead of checking for a NULL child at execution time, a node that
expects an optional component to be present more often than not checks
for a NULL child at construction time, and substitutes a viable
alternative node in its place.
(We'd like the parser to start emitting NULL a lot more once we teach
it to emit NULL for certain no-op productions like EmptyStatement and
VariableStatement, so, as a foundation, it's important for nodes with
NULL optional components to be fast.)
* kjs/Parser.cpp:

REGRESSION: 303-304: Embedded YouTube video fails to render- JS errors (16150) (Flash 9)
Get rid of unnecessary and incorrect security checks for plug-ins accessing JavaScript objects.
The way this used to work was that each NPObject that wrapped a JSObject would have a root object
corresponding to the frame object (used for managing the lifecycle) and an origin root object (used for
doing security checks).
This would prevent a plug-in from accessing a frame's window object if it's security origin was different
(some parts of the window, such as the location object, can be accessed from frames with different security
origins, and those checks are being done in WebCore).
Also, if a plug-in were to access a window object of a frame that later went away, it could lead to that
Window JSObject being garbage collected and the NPObject pointing to freed memory.
How this works now is that there is no origin root object anymore, and all NPObject wrappers that are created

Another round of grammar / parsing cleanup.
1. Created distinct parser calls for parsing function bodies vs
programs. This will help later with optimizing global variable access.
2. Turned Parser into a singleton. Cleaned up Lexer's singleton
interface.
3. Modified Lexer to free a little more memory when done lexing. (Added
FIXMEs for similar issues that I didn't fix.)
4. Changed Lexer::makeIdentifier and Lexer::makeUString to start
respecting the arguments passed to them. (No behavior change, but this
problem could have caused serious problems for an unsuspecting user of
these functions.)
5. Removed KJS_DEBUG_MEM because it was bit-rotted.
6. Removed Parser::prettyPrint because the same work was simpler to do
at the call site.

Cleaned up the JavaScript grammar a bit.
1. Changed BlockNode to always hold a child vector (which may be empty),
eliminating a few NULL-check branches in the common execution case.
2. Changed the Block production to correctly report its starting and
ending line numbers to the debugger. (It used to report its ending line
as its starting line.) Also, removed duplicate line-reporting code
inside the BlockNode constructor.
3. Moved curly braces up from FunctionBody production into parent
productions. (I had to move the line number reporting code, too, since
it depends on the location of the curly braces.) This matches the ECMA
spec more closely, and makes some future changes I plan easier.

empty Vectors.

- fix http://bugs.webkit.org/show_bug.cgi?id=11231
RegExp bug when handling newline characters
and a number of other differences between PCRE behvior
and JavaScript regular expressions:
+ single-digit sequences like \4 should be treated as octal
character constants, unless there is a sufficient number
of brackets for them to be treated as backreferences
+ \8 turns into the character "8", not a binary zero character
followed by "8" (same for 9)
+ only the first 3 digits should be considered part of an
octal character constant (the old behavior was to decode
an arbitrarily long sequence and then mask with 0xFF)
+ if \x is followed by anything other than two valid hex digits,
then it should simply be treated a the letter "x"; that includes
not supporting the \x{41} syntax
+ if \u is followed by anything less than four valid hex digits,
then it should simply be treated a the letter "u"
+ an extra "+" should be a syntax error, rather than being treated
as the "possessive quantifier"
+ if a "]" character appears immediately after a "[" character that
starts a character class, then that's an empty character class,
rather than being the start of a character class that includes a
"]" character
+ a "$" should not match a terminating newline; we could have gotten
PCRE to handle this the way we wanted by passing an appropriate option
Test: fast/js/regexp-no-extensions.html
* pcre/pcre_compile.cpp:
(check_escape): Check backreferences against bracount to catch both
overflows and things that should be treated as octal. Rewrite octal
loop to not go on indefinitely. Rewrite both hex loops to match and
remove \x{} support.
(compile_branch): Restructure loops so that we don't special-case a "]"
at the beginning of a character class. Remove code that treated "+" as
the possessive quantifier.
(jsRegExpCompile): Change the "]" handling here too.
* pcre/pcre_exec.cpp: (match): Changed CIRC to match the DOLL implementation.
Changed DOLL to remove handling of "terminating newline", a Perl concept
which we don't need.
* tests/mozilla/expected.html: Two tests are fixed now:
ecma_3/RegExp/regress-100199.js and ecma_3/RegExp/regress-188206.js.
One test fails now: ecma_3/RegExp/perlstress-002.js -- our success before
was due to a bug (we treated all 1-character numeric escapes as backreferences).
The date tests also now both expect success -- whatever was making them fail
before was probably due to the time being close to a DST shift; maybe we need
to get rid of those tests.

Fix <rdar://5578982> ASSERT in HashTable::checkTableConsistencyExceptSize beneath WebNotificationCenter
The bug was due to a mismatch between HashMap::remove and
HashTable::checkTableConsistency. HashMap::remove can delete the value
stored in the HashTable (by derefing it), which is not normally
allowed by HashTable. It's OK in this case because the value is about
to be removed from the table, but HashTable wasn't aware of this.
HashMap::remove now performs the consistency check itself before
derefing the value.
Darin noticed that the same bug would occur in HashSet, so I've fixed
it there as well.

next round of changes to JSRegExp (formerly PCRE)
This is a combination of converting to C++, tweaking the API, and adding
some additional optimizations.
Future steps will involve getting rid of the use of UTF-8 completely
(we'll use UTF-16 exclusively instead), eliminating more source files,
and some more speed-ups.
SunSpider says the current round is an 0.9% speed-up overall, and a
5.3% speed-up for regexp.
* JavaScriptCore.exp: Updated for new entry points.
* JavaScriptCore.pri:
* JavaScriptCore.vcproj/JavaScriptCore/JavaScriptCore.vcproj:
* JavaScriptCore.vcproj/dftables/dftables.vcproj:
* JavaScriptCore.xcodeproj/project.pbxproj:
* JavaScriptCoreSources.bkl:
* jscore.bkl:
Updated for new source file names and ForwardingHeaders.
* kjs/regexp.cpp:
(KJS::RegExp::RegExp): Changed to use the error message without calling
strdup on it and to pass the new types and options.
(KJS::RegExp::~RegExp): Removed the now-unneeded free of the error message.
(KJS::RegExp::match): Pass the new types and options.
* kjs/regexp.h: Update type of m_constructionError.
* pcre/AUTHORS: Update to reflect the status of the project -- we don't include
the Google parts, and this isn't the PCRE library, per se.
* pcre/COPYING: Ditto.
* pcre/dftables.cpp: Copied from JavaScriptCore/pcre/dftables.c.
(main): Removed unneeded ctype_digit.
* pcre/pcre.h: Convert to C++, tweak API a bit. Use UChar instead of JSRegExpChar.
* pcre/pcre_compile.cpp: Copied from JavaScriptCore/pcre/pcre_compile.c.
Moved a lot of private stuff used only within this file here from pcre_internal.h.
Renumbered the error codes.
(error_text): Use a single string with embedded nulls for the error text (I got
this idea from newer versions of PCRE).
(check_escape): Changed return type to be enum instead of int. Replaced ctype_digit
uses with isASCIIDigit.
(is_counted_repeat): Ditto.
(read_repeat_counts): Ditto.
(first_significant_code): Ditto.
(find_fixedlength): Ditto.
(could_be_empty_branch): Ditto.

(find_firstassertedchar): Ditto.
(jsRegExpCompile): Changed to take separate flags instead of an options int.
Also changed to call new/delete instead of pcre_malloc/free.
(jsRegExpFree): Ditto.
* pcre/pcre_exec.cpp: Copied from JavaScriptCore/pcre/pcre_exec.c.
Added a case that uses computed goto for the opcode loop, but did not turn it on.
Changed the RMATCH macro to handle returns more efficiently by putting the where
pointer in the new frame instead of the old one, allowing us to branch to the
return with a single statement. Switched to new/delete from pcre_malloc/free.
Changed many RRETURN callers to not set the return value since it's already
set correctly. Replaced the rrc variable with an is_match variable. Values other
than "match" and "no match" are now handled differently. This allows us to remove
the code to check for those cases in various rules.
(match): All the case statements use a macro BEGIN_OPCODE instead. And all the
continue statements, or break statements that break out of the outer case use
a macro NEXT_OPCODE instead. Replaced a few if statements with assertions.
(jsRegExpExecute): Use new/delete instead of pcre_malloc/free. Removed unused
start_match field from the match block.
* pcre/pcre_internal.h: Moved the last few configuration macros from pcre-config.h
in here. Removed various unused types. Converted from JSRegExpChar to UChar.
Eliminated pcre_malloc/free. Replaced the opcode enum with a macro that can be
used in multiple places. Unfortunately we lose the comments for each opcode; we
should find a place to put those back. Removed ctype_digit.
* pcre/pcre_maketables.cpp: Copied from JavaScriptCore/pcre/pcre_maketables.c.
(pcre_maketables): Got rid of the conditional code that allows this to be compiled
in -- it's only used for dftables now (and soon may be obsolete entirely).
Changed code for cbit_digit to not use isdigit, and took the "_" case out of the
loop. Removed ctype_digit.
* pcre/pcre_ord2utf8.cpp: Copied from JavaScriptCore/pcre/pcre_ord2utf8.c.
* pcre/pcre_tables.cpp: Copied from JavaScriptCore/pcre/pcre_tables.c.

* pcre/ucpinternal.h: Updated header.
* pcre/ucptable.cpp: Copied from JavaScriptCore/pcre/ucptable.c.
* wtf/ASCIICType.h: (WTF::isASCIIDigit): Removed a branch by changing from && to
& for this operation. Also added an overload that takes an int because that's
useful for PCRE. Later we could optimize for int and overload other functions in

getting characters by indexing into a string is very slow
This fixes one source of the slowness -- the conversion to an unused
Identifier as we call the get function from the slot -- but doesn't
fix others, such as the fact that we have to allocate a new UString::Rep

Speeds up string-base64 30%, and at least 0.5% overall.

Add a fast path for bitwise-and of two immediate numbers for a 0.7% improvement in SunSpider (4% bitop improvement).
This only improves bitwise-and performance, as the additional logic required
for similar code paths on or, xor, and shifting requires additional operations
and branches that negate (and in certain cases, regress) any advantage we might
otherwise receive.
This improves performance on all bitop tests, the cryptography tests, as well as
the string-base64 and string-unpack-code tests. No significant degradation on
any other tests.

Convert JavaScript internal function objects to use one class per
function. This avoids a switch statement inside what used to be
the shared function classes and will allow Shark to better analyze
the code.
To make this switch, the value property of the HashEntry was changed
to a union of an intptr_t (which is used to continue handle valueGetters)
and function pointer which points to a static constructor for the
individual new function objects.
SunSpider claims this is a 1.0% speedup.

an existing deleted sentinel, we would enlarge the entries vector, but would not

exact same thing. Moved the handling of opcodes higher than OP_BRA into the default
statement of the switch instead of doing them before the switch. This removes a
branch from each iteration of the opcode interpreter, just as removal of "op"
removed at least one store from each iteration. Last, but not least, add the

surrogate pair and the letter case can be handled efficiently.

remove unused PCRE features for speed
A first step toward removing the PCRE features we don't use.
This gives a 0.8% speedup on SunSpider, and a 6.5% speedup on
the SunSpider regular expression test.
Replaced the public interface with one that doesn't use the
name PCRE. Removed code we don't need for JavaScript and various
configurations we don't use. This is in preparation for still
more changes in the future. We'll probably switch to C++ and
make some even more significant changes to the regexp engine
to get some additional speed.
There's probably additional unused stuff that I haven't
deleted yet.
This does mean that our PCRE is now a fork, but I think that's
not really a big deal.
* JavaScriptCore.exp: Remove the 5 old entry points and add
the 3 new entry points for WebCore's direct use of the regular
expression engine.
* kjs/config.h: Remove the USE(PCRE16) define. I decided to flip
its sense and now there's a USE(POSIX_REGEX) instead, which should
probably not be set by anyone. Maybe later we'll just get rid of it
altogether.
* kjs/regexp.h:
* kjs/regexp.cpp:
(KJS::RegExp::RegExp): Switch to new jsRegExp function names and
defines. Cut down on the number of functions used.
(KJS::RegExp::~RegExp): Ditto.
(KJS::RegExp::match): Ditto.
* pcre/dftables.c: (main): Get rid of ctype_letter and ctype_meta,
which are unused.
* pcre/pcre-config.h: Get rid of EBCIDIC, PCRE_DATA_SCOPE, const,
size_t, HAVE_STRERROR, HAVE_MEMMOVE, HAVE_BCOPY, NEWLINE,
POSIX_MALLOC_THRESHOLD, NO_RECURSE, SUPPORT_UCP, SUPPORT_UTF8,
and JAVASCRIPT. These are all no longer configurable in our copy
of the library.
* pcre/pcre.h: Remove the macro-based kjs prefix hack, the PCRE
version macros, PCRE_UTF16, the code to set up PCRE_DATA_SCOPE,
the include of <stdlib.h>, and most of the constants and
functions defined in this header. Changed the naming scheme to
use a JSRegExp prefix rather than a pcre prefix. In the future,
we'll probably change this to be a C++ header.
* pcre/pcre_compile.c: Removed all unused code branches,
including many whole functions and various byte codes.
Kept changes outside of removal to a minimum.

other small like optimizations.

Also got rid of many of the tables that we don't use.
* pcre/pcre_tables.c: Removed the unused Unicode property tables.

_pcre_ucp_othercase.
* pcre/pcre_xclass.c: (_pcre_xclass): Removed uneeded support

* wtf/FastMallocPCRE.cpp: Removed unused bits. It would be good
to eliminate this completely, but we need the regular expression
code to be C++ first.

change property map data structure for less memory use, better speed
The property map now has an array of indices and a separate array of
property map entries. This slightly slows down lookup because of a second
memory acess, but makes property maps smaller and faster to iterate in
functions like mark().
SunSpider says this is 1.2% faster, although it makes the bitwise-end test
more than 10% slower. To fix that we'll need to optimize global variable lookup.

Much supporting work done by Maciej Stachowiak, Maks Orlovich, and
Cameron Zwarich.
AST transfom to replace slow resolve nodes with fast local variable
alternatives that do direct memory access. Currently, only ResolveNode
provides a fast local variable alternative. 6 others are soon to come.
16.7% speedup on SunSpider.
Most of this patch is just scaffolding to support iterating all the
resolve nodes in the AST through optimizeResolveNodes(). In
optimizeResolveNodes(), most classes just push their child nodes onto
the processing stack, while ResolveNodes actually replace themselves in
the tree with more optimized alternatives, if possible.
Here are the interesting bits:
* kjs/nodes.h: Added PlacementNewAdoptTag, along with implementations
in Node and ResolveNode. This tag allows you to use placement new to
swap out a base class Node in favor of a subclass copy that holds the
same data. (Without this tag, default initialization would NULL out
RefPtrs, change line numbers, etc.)
* kjs/nodes.cpp:
(KJS::ResolveNode::evaluate): Since we're taking the slow path, ASSERT
that the fast path is impossible, to make sure we didn't leave anything
on the table.

remove GroupNode to simplify AST and possibly get a modest speedup
This patch removes 4 node types: GroupNode, PropertyNameNode,
FunctionCallParenBracketNode, and FunctionCallParenDotNode.
To remove GroupNode, we add knowledge of precedence to the tree nodes,
and use that when serializing to determine where parentheses are needed.
This means we no longer have to represent parentheses in the tree.
The precedence values are named after productions in the grammar from the
JavaScript standard.
SunSpider says this is an 0.4% speedup.
* kjs/function.h:
* kjs/function.cpp: Removed escapeStringForPrettyPrinting -- it's part of
serialization, so I moved it to the file that takes care of that.
* kjs/grammar.y: Changed makeGetterOrSetterPropertyNode to use 0 to
indicate failure instead of a separate boolean. Got rid of PropertyNameNode
by merging the PropertyName rule into the Property rule (which was easier
than figuring out how to pass the Identifier from one node to another).
Got rid of GroupNode, nodeInsideAllParens(), FunctionCallParenBracketNode,
and FunctionCallParenDotNode.
* kjs/nodes.h: Removed unused forward declarations and Operator values.
Added Precedence enum, and precedence function to all nodes. Removed

Removed FunctionCallParenBracketNode and FunctionCallParenDotNode.
* kjs/nodes.cpp: Removed Node::nodinsideAllParens, GroupNode, and PropertyNameNode.
(KJS::PropertyListNode::evaluate): Changed code to get name directly instead
of converting it from an Identifier to a jsString then back to a UString
then into an Identifier again!
* kjs/nodes2string.cpp: Changed special-token implementation to use a separate
function for each of Endl, Indent, Unindent, and DotExpr instead of using a
single function with a switch. Added a precedence that you can stream in, to
cause the next node serialized to add parentheses based on that precedence value.

- numerous HashTable performance improvements
This does not quite add up to a measurable win on SunSpider, but it allows a
follow-on > 3% improvement and probably helps WebCore too.
I made the following improvements, among others:
- Made HashFunctions note whether it is ok to compare a real value with the equal() function
to the empty or deleted value, and used this to optimize the comparisons done in hash lookup.
- Specialized lookup so it doesn't have to do so many extra branches and build so many extra
std::pairs for cases that don't need them. There are now four versions, one for read-only access,
two for writing, and one folded directly into add() (these all were improvments).
- Made HashMap::get() use lookup() directly instead of find() to avoid having to build iterators.
- Made a special constructor for iterators that knows it points to
a valid filled cell and so skips updating itself.

Shrink the size of an activation object by 1 word
This is in preparation for adding a symbol table to the activation

The basic strategy here is to rely on the mutual exclusion between
the arguments object pointer and the function pointer (you only need
the latter in order to create the former), and store them in the same
place. The LazyArgumentsObject class encapsulates this strategy.
Also inlined the ArgumentsImp constructor, for good measure.

Re-structured variable and function declaration code.
Command-line JS iBench shows no regression.
Here are the changes:
1. Function declarations are now processed at the same time as var
declarations -- namely, immediately upon entry to an execution context.
This does not match Firefox, which waits to process a function
declaration until the declaration's containing block executes, but it
does match IE and the ECMA spec. (10.1.3 states that var and function
declarations should be processed at the same time -- namely, "On
entering an execution context." 12.2 states that "A Block does not
define a new execution scope.")
2. Declaration processing proceeds iteratively now, rather than
recursively, storing the nodes is finds in stacks. This will later
facilitate an optimization to hold on to the gathered declaration nodes,
rather than re-fetching them in every function call.

Removed surprising self-named "hack" that made nested functions
available as named properties of their containing functions, and placed
containing function objects in the scope chains of nested functions.
There were a few reasons to remove this "hack:"
1. It contradicted FF, IE, and the ECMA spec.
2. It incurred a performance penalty, since merely parsing a function
required parsing its body for nested functions (and so on).
3. SVN history contains no explanation for why it was added. It was just
legacy code in a large merge a long, long time ago.

specialization. This brings inline Vectors one step closer to true
stack-allocated arrays.
Also changed abort() to CRASH(), since the latter works better.

This patch is a merge of KDE r670547, with substantial modification

It fixes do-while statements to evaluate to a value. (They used
to evaluate to the empty value in all cases.)
It also fixes SourceElementsNode to maintain the value of abnormal
completions like "break" and "continue."
It also re-works the main execution loop in SourceElementsNode so that
it (1) makes a little more sense and (2) avoids unnecessary work. This
is a .28% speedup on command-line JS iBench.
