637a21952f Added general pre- and postfix count operations to top-level compiler.
Until now we only supported postfix operations on global variables.
This change add generic count operations to the top-level compiler.

I tried to re-use code from the code generator used for assignment expressions
where possible.

44b7c59eb5 Extend the maximum size map space
On 32-bit the maps are now aligned on a 32-byte boundary in order to encode more maps during compacting GC. The actual size of a map on 32-bit is 28 bytes making this change waste 4 bytes per map.

On 64-bit the encoding for compacting GC is now using more than 32-bits and the maps here are still pointer size aligned. The actual size of a map on 64-bit is 48 bytes and this change does not intruduce any waste.

My choice of 16 bits for kMapPageIndexBits for 64-bit should give the same maximum number of pages (8K) for map space. As maps on 64-bit are larger than on 32-bit the total number of maps on 64-bit will be smaller than on 32-bit. We could consider raising this to 17 or 18.

I moved the kPageSizeBits to globals.h as the calculation of the encoding really depended on this.

There are still an #ifdef/#endif in objects.h and this constant could be moved to globaks.h as well, but I kept it together with the related constants.

All the tests run in debug mode with additional options --gc-global --always-compact as well (except for a few tests on which also fails before this change when run with --gc-global --always-compact).

0bf2822266 The toplevel code generator assumed that declarations did not shadow
parameters.  This could case the initial value to be lost or worse, a
crash.

Fix by handling the case of a declaration shadowing both
stack-allocated parameters and those in the arguments object.

This is related to V8 issue 540.

53fbd5932a Perform string add in generated code on IA-32 platforms
This adds a code stub which can do most of what Heap::AllocateConsString can do. It bails out if the result cannot fit in new space or if the result is a short (flat) string and one argument is an ascii string and the other a two byte string. It also bails out if adding two one character strings as Heap::AllocateConsString has special handling of this utilizing the symbol table. The stub is used both for the binary add operation and for StringAdd calls from runtime JavaScript files. Extended the string add test to cover all sizes of flat result stings.

34dee0319c Remove the typeof state threaded through the code generator. It was
used to signal that an expression was the immediate subexpression of
typeof, or (?) in the arm of a conditional expression itself in the
typeof state.

It was inconsistently consulted.  It was not used for property loads,
but only for slot loads.  This means that we matched the Webkit JSC
(not Spidermonkey) behavior for:

typeof(true ? x : y)  // throws ReferenceError

and we matched the SpiderMonkey behavior (not JSC) for:

with ({}) { typeof(true ? x : y) }  // ==> "undefined"

Now we are expected to match the JSC behavior in all cases.

Right now, the fast compiler produces code very similar to
the existing code generator. We may consider different ways to 
further compact the generated code for top-level code.

ARM always goes through a runtime function to initialize computed
properties in an object literal whereas IA32 and x64 use StoreIC.

fbc0eaa13d Added support for array literals to the toplevel compiler. They are
currently compiled the same as with the optimizing compiler: they are
cloned from a boilerplate object and the boilerplate objects are
lazily constructed.

Also changed argument pushing on ARM to use stm (store multiple),
which required changing the order of arguments to the runtime
functions DeclareGlobals and NewClosure.  They were only used from
generated code.

Finally, changed the toplevel code generator so that stack pops to
discard a temporary became addition to the stack pointer on ia32 and
x64.

fb038bf146 Two changes, one a refactoring and one that affects V8's JS semantics.
1. Change the AST node type CallNew to be a subclass of Expression
   rather than Call.  It's not really a call but it just happens to
   have the same fields.

2. Change our error reporting for invalid left-hand sides in for-in
   statements, pre- and postfix count expressions, and assignments.
   Before we signaled a syntax error at compile time *unless* the LHS
   was a function call or 'new' expression, in which case we signaled
   a reference error at runtime.  Now we signal a reference error at
   runtime in all cases.  This matches the JSC behavior in Safari 4.

677c043fee Handle array construction on native code.
The construction of arrays when using the the Array function either as a constructor or a normal function is now handled fully in generated code in most cases. Only when Array is called with one argument which is either negative or abowe JSObject::kInitialMaxFastElementArray (which is currently 1000) or if the allocated object cannot fit in the room left in new space is the runtime system entered.

Two new native code built-in functions are added one for normal invocation and one for the construct call. The existing C++ builtin is renamed, but kept. When the normal invocation cannot be handled in generated code the C++ builtin is called. When the construct invocation cannot be handled in native code the generic construct stub is called (which will end up in the C++ builtin through a construct trampoline).

One thing that might be changed is preserving esi (constructor function) during the handling of a construct call. We know precisily what function we where calling anyway and can just reload it. This could remove the parameter construct_call to ArrayNativeCode and remove the handling of this from that function.

The X64 and ARM implementations are not part of this changelist.

34d6ff7606 Implemented missing pieces of the debugger for ARM.
The main piece of this change was to add support for break on return for ARM. On ARM the normal js function return consist of the following code sequence.

  mov sp, fp
  ldmia sp!, {fp, lr}
  add sp, sp, #4
  bx lr

to a call to the debug break return entry code using the following code sequence

  mov lr, pc
  ldr pc, [pc, #-4]
  <debug break return entry code entry point address>
  bktp 0

The values of Assembler::kPatchReturnSequenceLength and Assembler::kPatchReturnSequenceLength are somewhat misleading, but they fit the current use in the debugger. Also Assembler::kPatchReturnSequenceLength is used in the IC code as well (for something which is not related to return sequences at all). I will change that in a separate changelist.

For the debugger to work also added recording of the return sequence in the relocation info and handling of source position recording when a function ends with a return statement.

Used the constant kInstrSize instead of sizeof(Instr).

Passes all debugger tests on both simulator and hardware (only release mode tested on hardware).

bbc3c97c2c Support stepping out for recursive functions.Simply flooding JS function from the calling stack frame with one shot breakpoints is not enough to support step out action in all cases since the function on top of the stack may be turn recursive and we may end up flooding itself. To overcome this a pointer to the stack frame where the debugger should be invoked after stepping out is strored in the debugger.Chromium bug:http://code.google.com/p/chromium/issues/detail?id=17967

ae062d5df1 Added new scope type ScopeIterator::ScopeTypeCatch for with generated from catch blocks.
Removed a false assertion in ScopeIterator that assumed context extension to never be a JSContextExtensionObject.

The context extension object in a 'with' context is JSContextExtensionObject iff the 'with' statement is generated from a catch block in order to extend its local scope with a variable holding exception object. This is how we differentiate 'catch' scope from 'with' scope.

ab54e95377 Support stepping in functions called using CallFunction stub. When Debug::PrepareStep is called to prepare 'step in' and current code target is CallFunction stub, the debugger will find function being called on the expression stack and flood it with one shot breakpoints.
BreakLocationIterator changed to treat 'debugger;' statements as a possible break location. Since 'debugger;' statement should always invoke debugger it is hanled in a special way.

717394492d Generate specialized constructor code for constructing simple objects.
For objects which only have simple assignments of the form this.x = ...; a
specialized constructor stub is now generated. This generated code allocates the
object and fills in the initial properties directly. If this fails for some
reason code continues in the generic constructor stub which in turn might pass
control to the runtime system.

Added counter to see how many objects are constructed using a specialized stub.

The specialized stub is only implemented for ia32 architecture in this change.
For x64 and ARM the generic construct stub is used.

This is change is identical to http://codereview.chromium.org/174392 (committed in r2753 and reverted in r2754) except that a few parts have already been committed from http://codereview.chromium.org/173469 (committed in r2762).

4e03645dc4 Analyze functions for assignment to this properties.
During parsing functions are analyzed for statements of the form this.x = ...;. These assignments are categorized in two types: simple and non simple. The simple ones are where the right hand side is known to be either a constant or an argument to the function. If a function only contains statements of this type the property names are collected and for the simple assignments the index of the argument or the constant value assigned are stored as well.

When the initial map for a function is created and the function consists of only this type of assignemnts the initial map is created with a descriptor array describing these properties which will be known to always exist in an object created from the function.

The information on this property assignments is not collected during pre-parsing so if compiling using pre-parse data these optimization hints are not available.

Next step will be to use the information collected for the simple assignments to generate constructor code which will create and initialize the object from this information without calling the code for the function.

d87f83c5f8 Fix issue 427: JS tick processor now works out-of-the-box for Chromium on Windows.
MSVS names '.map' file using only module's name, so both 'a.exe' and 'a.dll' will have 'a.map' file. To distinguish an originating module, we're now checking for image base which is always 00400000 for .exe files, and not 00400000 for .dlls.

Verified that windows-tick-processor can now process logs from Chromium using .map file generated for 'chrome.dll', an that it still works for V8's 'shell.exe'.

e0b829b1a5 TickProcessor: more accurate mapping of statically compiled code on Linux.
'nm' is now called with an option to report function code sizes. Static code entries are restricted to the sizes reported, and the remaining unnamed code is attributed to a library as a whole. This makes reports more accurate, as some functions are tiny, but has chunks of unnamed code behind them.

This change doesn't affect reporting on Windows, as in .map files function code sizes aren't specified.

cba9c183a0 In Chrome several tabs may share the same v8 instance. Each of those tabs can be inspected with its own devtools window. When such devtools window closes we need to clear all breakpoints that belong to it. Notion of breakpoint group enables us to do that.
Storing the breakpoints on the client(in a different process) would be inreliable since 1) it may crash and 2) some 'setbreakpoint' requests may be not processed yet by the time devtools window closes.

118a2ccc8e When Error.collectStackTraces is set to true all new instances of
Error, ReferenceError, etc. are given a stack property that gives a
stack trace.  Here's an example stack trace:

ReferenceError: FAIL is not defined
    at Constraint.execute (deltablue.js:527)
    at Constraint.recalculate (deltablue.js:426)
    at Planner.addPropagate (deltablue.js:703)

    at chainTest (deltablue.js:809)
    at deltaBlue (deltablue.js:881)
    at deltablue.js:888

If Error.prepareStackTrace holds a function this function is used to
format the stack trace, for instance allowing code generators to
customize the way stack traces are reported to make them easier to
process.

Next step: performance measurements to see if it is feasible to turn
this on by default.

882614391f Add scope chain information to the debugger.
For each frame it is now possible to request information on the scope chain. Each scope in the chain can have one of the types local, global, with and closure. For scopes of type global and with the mirror for the actual global or with object is available. For scopes of type local and closure a plain JavaScript object with the materialized content of the scope is created and its mirror is returned. Depending on the level of possible optimization the content of the materialized local and closure scopes might only contain the names which are actually used.

To iterate the scope chain an iterator ScopeIterator have been added which can provide the type of each scope for each part of the chain. This iterator creates an artificial local scope whenever that is present as the context chain does not include the local scope.

To avoid caching the mirror objects for the materialized the local and closure scopes transient mirrors have been added. They have negative handles and cannot be retrieved by subsequent lookup calls. Their content is part of a single response.

For debugging purposes an additional runtime function DebugPrintScopes is been added.

Added commands 'scopes' and 'scope' to the developer shell and fixed the dir command.

d498361c5f Add more debugging information to scripts compiled through eval.
Scripts now have a compilation type which can be host, eval or JSON. Host scripts are compiled through the API, eval scripts are compiled through call to evan and JSON scripts are compiled as a result of calling JSON.parse.

For scripts scripts compiled through eval the JavaScript function in top of the stack and the pc offset into the code is stored in the script object. This makes it possible to calculate the source position of the eval call later when requested. This information can be obtained through the script mirror object and is part of the script mirror JSON serialization for the debugger protocol.

Moved the enumeration ScripType into class Script and remamed to Type. The new compilation type enumeration is also inside the class Script.

This information is now shown when using the scripts command in he developer shell debugger.

94879a93b0 Add a script cache to the debugger
When loaded scripts are requested this cache is filled with all the script objects in the heap. Hereafter its content is kept in sync with the active scripts in the heap through the notifications of new scripts compiled and by using weak handles to get notified when a script is collected.

Through the tracking of collected scripts the debugger event OnScriptCollected have been added to notify a debugger that a script previously returned through the scripts command is no longer in use.

Make the ComputeIntegerHash globally available.

Moved clearing of the mirror cache to when debugger is really left. Previously recursive invocations of the debugger cause the mirror cache to be cleared causing handles to become either stale or reference other objects.

aa2c33126c TickProcessor script reimplemented in JavaScript.
This is an effort to reuse profiler data processing code both in
TickProcessor and Dev Tools Profiler. The old Python implementation
will be removed.

The new TickProcessor works almost identical to the previous one.
However, it has some differences:

1. Not very useful "Call profile" section is replaced with a new
   WebKit-like "Bottom up (heavy) profile" which shows the most
   expensive functions together with their callers. I used it
   personally in order to find and remove bottlenecks in the
   tickprocessor script itself, and found it quite helpful.

2. Code entries with duplicate names (they occur for RegExes, stubs
   and sometimes for anonymous Function objects) are now distinguished
   by adding an occurence number inside curly brackets.

3. (Address -> code entry) mapping is more precise in boundary cases.

4. Windows version no more requires specifying .map file location.

5. Works faster.

e9aa21849b Reimplement Splay Tree in JavaScript (and add unit tests!).
This is the first step in reimplementing tick processing scripts in
JavaScript. The goal is to have the same source both for Dev Tools and
Golem, so Python implementation will be removed to avoid code
duplication.

The implementation follows the Dev Tools style: namespaces and JSDocs
are used.

a74fcf458c Fixed the step in handling for function.apply.
The generic step-in mechanism floods the function called with break points to ensure a break is hit when entering the function. This generic mechanism was also used for function.apply. The code for function.apply contains a keyed load IC which was patched when stepping into function.apply. However function.apply enteres an internal frame not a JavaScript frame. This caused the logic for returning from the break in function.apply to fail as it forced a jump to the IC on the top JavaScript frame. The top JavaScript frame was the frame for the function calling function.apply not the frame for the apply function. Now returning from the break point in the keyed load IC in the apply code caused a jump to the code for the call IC for the function calling function.apply in the first place. Not a pretty sight.

Step-in now handles function.apply as a separate case where the actual JavaScript function called through apply is flodded with breakpoints instead of the function.apply function.

8dffcb9efa Flush ICs when adding setters to an object or setting a __proto__ to
an object that holds a setter.  If there are no store ics then no
flushing is done.  The implementation has been tweaked so that no ICs
are cleared during normal context creation.
This may cost us some performance but I'm submitting it as it is and
if there are problems we can either decide to be smarter about when,
what and/or how we clear, or back this change out altogether.
