Reviewed by Oliver Hunt.

A little more debugger action: filled in op_debug. All debugger control
flow works now, but variable inspection and backtraces still don't.


SunSpider reports no change.

  • VM/CodeGenerator.cpp: Changed op_debug to accept line number parameters.
  • VM/Machine.cpp: (KJS::Machine::getFunctionAndArguments): Moved op_debug into a NEVER_INLINE function to avoid a stunning 10% performance regression. Also factored out a common function for retrieving the function and arguments from a call frame.
  • kjs/JSActivation.cpp: (KJS::JSActivation::createArgumentsObject): Use the new factored out function mentioned above.
  • kjs/Parser.cpp: (KJS::Parser::parse): Increment m_sourceId before assigning it, so the sourceId we send to the debugger matches the sourceId recorded in the node.
  • kjs/nodes.cpp: Emit debugging hooks.

Bug 19024: SQUIRRELFISH: ASSERTION FAILED: activation->isActivationObject() in Machine::unwindCallFrame
<https://bugs.webkit.org/show_bug.cgi?id=19024>

Reviewed by Maciej

This fixes a number of issues. The most important is that we now check every register
file for tainting rather than just looking for function register files as that was
insufficient. Additionally guarded against implicit re-entry into Eval code.

Also added a few additional assertions to reduce the amout of time between something
going wrong and us seeing the error.

A little more debugger action: emit opcodes for debugger hooks. Right
now, the opcode implementation is just a stub.

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

A little more debugger action: implemented the exception callback.


SunSpider reports a .2% speedup. Not sure what that's about.

  • VM/CodeBlock.h: A little refactoring here. Store a pointer to our owner ScopeNode so we can retrieve data from it. This allows us to stop storing copies of the data ourselves. Also, store a "this" register instead of a code type, since we were only using the code type to calculate the "this" register.
  • VM/CodeGenerator.cpp: (KJS::CodeGenerator::generate): Calculate the "this" register mentioned above. Also, take care of removing "this" from the symbol table after codegen is done, since relying on the timing of a destructor for correct behavior is not so good.
  • VM/Machine.cpp: (KJS::Machine::throwException): Invoke the debugger's exception callback. (KJS::Machine::privateExecute): Use the "this" register mentioned above.

is being replaced by the Inspector's debugger, and Drosera is the only
client of WebScriptDebugServer, it makes more sense to get rid of
WebScriptDebugServer than to update it to keep it working.

We can't actually remove WebScriptDebugServer entirely yet, so I've
just made it non-functional. This will completely break Drosera, but
as stated above, Drosera's days are numbered anyway.

Bug 18752: SQUIRRELFISH: exceptions are not always handled by the vm
<https://bugs.webkit.org/show_bug.cgi?id=18752>

Reviewed by Darin

Replace old attempt at "branchless" exceptions as the extra information
being passed made gcc an unhappy compiler, replacing these custom toNumber
calls with ordinary toNumber logic (by relying on toNumber now preventing
side effects after an exception has been thrown) provided sufficient leeway
to add the additional checks for the remaining unchecked cases.

This leaves only toString conversions in certain contexts as possibly
misbehaving.

  • kjs/debugger.h: Changed sourceParsed to take a SourceProvider, to reduce copying, and not to return a value, because pausing execution after parsing is complicated, and no clients needed that ability, anyway.
  • kjs/grammar.y: Make sure never to pass a NULL SourceElements* to didFinishParsing -- that simplifies some code down the road.

It's not clear how r31100 changed the top-level frame in the frame path
to be named "1". The change definitely wasn't related to any expected
behavior in r31100, which was about default margin-bottom for form
elements in quirks mode.

It's also not clear how squirrelfish changes things back.

Sam mentioned that the test result changes intermittently on trunk.

I've restored -[WebScriptObject setException] and

Instead of mucking around in the JavaScript engine's execution state,
throwing an exception sets a global exception string, along with the
environment in which to throw it. An ObjC callback checks the global
exception string and, if it's non-nil and the environment matches the
current exceution environment, throws the global exception string as a
JS exception.

I also removed the old currentGlobalObject infrastructure: it's no longer

Bug 18643: SQUIRRELFISH: need to support implicit function calls (valueOf, toString, getters/setters)
<https://bugs.webkit.org/show_bug.cgi?id=18643>

Reviewed by Maciej

Prevent static slot optimisation for new variables and functions in
globally re-entrant code called from an an implicit function call.

This is necessary to prevent us from needing to resize the global
slot portion of the root RegisterFile during an implicit (and hence
unguarded) function call.

Partial fix. This results in all implicit calls to toString or valueOf
executing in a separate RegisterFile, so ensuring that the the pointers
in the triggering interpreter don't get trashed. This still leaves the
task of preventing new global re-entry from toString and valueOf from
clobbering the RegisterFile.

RS by Oliver Hunt on moving JSArguments.cpp out of AllInOneFile.cpp.

Substantially more handling of "arguments": "arguments" works fully

Degenerate handling of "arguments" as a property of the activation
object. Currently, we just return a vanilla object.

SunSpider reports no change.

Fixes:

ecma_3/Function/regress-94506.js.

Reveals to have been secretly broken:

ecma_3/Function/15.3.4.3-1.js
ecma_3/Function/15.3.4.4-1.js

These tests were passing incorrectly. testkjs creates a global array
named "arguments" to hold command-line arguments. That array was
tricking these tests into thinking that an arguments object with length
0 had been created. Since our new vanilla object shadows the global
property named arguments, that object no longer fools these tests into
passing.

Net change: +1 failing test.

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.

Bug 18619: Support continue, break, and return in try .. finally blocks
<https://bugs.webkit.org/show_bug.cgi?id=18619>

Reviewed by Maciej

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.

This is somewhat more convoluted than the simple hadException checks
we currently use. Instead we use special toNumber conversions that
select between the exception and ordinary vPC. This allows us to
remove any branches in the common case (incrementing a number).

  • 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
-> JS 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.

Fixed two bugs in register allocation for function calls:

(1) op_call used to allocate codeBlock->numVars too many registers for
each call frame, due to duplicated math. Fixing this revealed...

(2) By unconditionally calling resize(), op_call used to truncate the
register file when calling a function whose registers fit wholly within
the register file already allocated by its caller.

Support for re-entrant execution of global code (global code -> built-in
function -> global code).

Keep a stack of register files instead of just one. Globals propogate
between register files as the register files enter and exit the stack.

An activation still uses its own register file's base as its
registerBase, but the global object uses the register file *stack*'s
registerBase, which updates dynamically to match the register file at
the top of the stack.

2) Adjust argc and argv appropriately for native constructor calls.

3) Assign return value in a more straightforward way in op_ret since this is actually

maintenance code into a proper "RegisterFile" class.

There's a subtle change to the register file's internal layout: for
global code / the global object, registerOffset is always 0 now. In
other words, all register counting starts at 0, not 0 + (number of
global variables). The helps simplify accounting when the number of

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.

  • wtf/Vector.h: Added an accessor for an indirect pointer to the vector's buffer, which we currently use (incorrectly) for registerBase. This is temporary scaffolding to allow us to change client code without changing behavior.

Support for evaluating multiple scripts in the same global environment.
(Still don't support re-entrant evaluation yet.)

The main changes here are:

(1) Obey the ECMA 10.1.3 rules regarding how to resolve collisions when
a given symbol is declared more than once. (This patch fixes the same
issue for function code, too.)

(2) In the case of var and/or function collisions, reuse the existing
storage slot. For global code, this is required for previously
generated instructions to continue to work. For function code, it's
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 ASSERT to account for the fact that symbol indexes are all negative.

JavaScriptCore:

2008-03-30 Geoffrey Garen <ggaren@apple.com>

Reviewed by Oliver Hunt.

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, to encourage the compiler to inline the Vector code.
  • kjs/CallData.h: Added. (KJS::): CallData is a union because eventually native calls will stuff a function pointer into it, to eliminate the callAsFunction virtual call.
  • kjs/function.cpp: (KJS::FunctionImp::callAsFunction): Changed this to an ASSERT since it's not implemented yet.
  • kjs/list.h: Made the List class two-faced, to support the old way and the new way during this transition phase: lists can be made read-only with just a pointer and a legnth, or you can append to them one item at a time.
  • kjs/value.h: (KJS::jsUndefined): Marked this function ALWAYS_INLINE for the benefit of a certain compiler that doesn't know what's best for it.

Reproducible crash with PAC file

Naively moving JavaScriptCore into thread-specific data was inappropriate in the face of
exiting JavaScriptCore API clients, which expect a different therading model. Temporarily

Fix scrolling issues by implementing transitionToCommittedNewPage() so the scroll positions are reset when a new page is loaded, and also maintained so that back and next restore the scroll positions as well. This also simplifies the logic for initializing and managing wxWebView.

Three layout tests are fixed:

fast/js/toString-elision-trailing-comma.html
fast/js/toString-prefix-postfix-preserve-parens.html
fast/js/kde/lval-exceptions.html


Functions now save a shared subrange of the original source used
to make them (so in the common case this adds no storage above the
memory cache).


  • kjs/SourceProvider.h: Added. (KJS::SourceProvider): New abstract base class for classes that provide on-demand access to the source for a JavaScript program. This allows function objects to have access to their original source without copying. (KJS::UStringSourceProvider): SourceProvider subclass backed by a KJS::UString. (KJS::UStringSourceProvider::create): (KJS::UStringSourceProvider::getRange): (KJS::UStringSourceProvider::data): (KJS::UStringSourceProvider::length): (KJS::UStringSourceProvider::UStringSourceProvider):
  • kjs/SourceRange.h: Added. (KJS::SourceRange::SourceRange): Class that holds a SourceProvider and a character range into the source, to encapsulate on-demand access to the source of a function. (KJS::SourceRange::toString):
  • VM/Machine.cpp: (KJS::eval): Pass a UStringSourceProvider to the parser.
  • kjs/Parser.cpp: (KJS::Parser::parse): Take a SourceProvider and pass it on to the lexer.
  • kjs/Parser.h: (KJS::Parser::parse): Take a SourceProvider.
  • kjs/lexer.cpp: (KJS::Lexer::setCode): Take a SourceProvider; keep it around, and use it to get the raw buffer and length.
  • kjs/lexer.h: (KJS::Lexer::sourceRange): Convenience function to get a source range based on the lexer's source provieder, and char offsets right before and after the desired range.
  • kjs/function.cpp: (KJS::globalFuncEval): Pass a UStringSourceProvider to the parser.
  • kjs/function_object.cpp: (KJS::functionProtoFuncToString): Use toSourceString to get the source. (KJS::FunctionObjectImp::construct): Give the parser a UStringSourceProvider.
  • kjs/grammar.y: When parsing a function declaration, function expression, or getter or setter, tell the function body about its SourceRange.
  • kjs/interpreter.cpp: (KJS::Interpreter::checkSyntax): Pass a SourceProvider to the parser. (KJS::Interpreter::evaluate): Pass a SourceProvider to the parser.
  • kjs/interpreter.h:
  • kjs/nodes.h: (KJS::FunctionBodyNode::setSource): Establish a SourceRange for this function. (KJS::FunctionBodyNode::toSourceString): Get the source string out of the SourceRange. (KJS::FuncExprNode::): Take a SourceRange and set it on the body. (KJS::FuncDeclNode::): ditto
  • kjs/testkjs.cpp: (prettyPrintScript): Use a SourceProvider appropriately.
