496868722f Added fast support for Math.pow. This simply calculates the result using the 
same method as the old powi version in runtime.cc and also checks if
the exponent is 0.5 or -0.5 in which case we calculate the square root or 
reciprocal value of the square root.

8398287070 Refactor the code cache to handle large number of properties on the global object. 
A separate object type for the code cache have been added. This object has two different code caches. The first one (default_cache) is a fixed array organized in the same way as the as the code cache was before. The second cache (global_access_cache) is for code stubs to access the global object. This cache is organized as a hash table taking the property name and code flags as the key.

The reason for separating the global access stubs into a hash table representation is that the number of these is not bounded in the same was as the other types.

d955c20beb Fix reliability crash caused by wrong assert. 
These two asserts in ComputeEntryFrame are wrong since the
virtual frame already knows how to deal with the number type
information of copy elements: We do not store type 
information with copy elements. Instead the backing element
contains the type information.

Change the implementation of lastIndexOf method of String. Convert the
strings in question to Vector<char> or Vector<uc16> and execute simple
search algorithm on them.

The difference in speed on 500k character string is about 10x.

a9202fc45d Begin using a list of bailouts instead of a singleton in the fast code generator. 
A list of bailout descriptions is kept in the CompilationInfo
structure that is shared between the primary and secondary code
generators.  The primary adds a description to the list for each
bailout position.

Responsibility for binding labels is moved from the primary to the
secondary code generator. All the labels still target the start of the
secondary code and the compilation state of the primary is still
ignored.

Move the compilation mode flag to the CompilationInfo.

ec86513519 Make class BitField able to use 32 bits of a uint32. 
Although algorithmically correct, the compiler would not allow to instantiate
a BitField that uses all 32 bits without warnings about a too large shift
count. As a consequence we were limited to 31 bit values when using BitField.

This happened when instantiating a bitfield BitField<T, shift, size> with 
[shift=0, size=32] or [shift=31, size=1] or more general any 
[shift=X, size=32-X]

As side-effect of the new implementation the compiler now warns if we ever
try instantiating a bitfield with size 0.

e1041c9f9c Introduce 'trivial' expressions, use them for this property assignments. 
Add a (currently) syntactic predicate to AST expression nodes telling
whether they are 'trivial'.  Trivial expressions have no side effects,
do not require storage to be allocated for them, and can be evaluated
out of order (because their value does not change between when they
are visited by the code generator as expressions in the AST and when
it is consumed).

Mark 'this' and literals as trivial.  Allow them to be pushed on the
virtual frame.  Make use of them to push 'this' more lazily in this
property assignments.

Replaced IsValid by IsPropertyOrTransition and used IsProperty in most
of the places where IsValid was used before.  Most of the time when
inspecting a lookup result we really want to know if there is a real
property present.  Only for stores are we interested in transitions.

Moved all the logic to a function on SharedFunctionInfo (including the flag check) to make things more readable.

Changed the check for setter to do a lookup for a named setter for each of the properties assigned in the constructor.

Added tests using accessors and interseptors set through the API.

Added fast case objects to the mjsunit test.

3c0d77f32e Fix stack corruption when calling non-function. 
Fix for issue 603.

Revision r3484 removed the property name from the call stack for
call ICs.  When a non-function was called via a call IC and
Function.prototype.call, an extra value was left on the stack that the
caller could not know to clean up.

Fix is to change the JS builtin used for calling non-functions.  It
now gets the callee as receiver, rather than iterating stack frames
and finding it on the expression stack of its JS caller.

1c2b2ac9c6 Fix construction of simple objects with setters on prototype 
Simple objects which are constructed without calling the actual constructor function did not take setters defined on prototype chain of the new object into account.

Constructing objects this way is now not done if there are setters involved on the prototype chain of the new object.

This only fixes the case where the setter is found when the first object from a constructor is created. If the prototype chain is changed new objects will on take any change to setters into account.

ad9ea637be Don't externalize fresh strings. 
With the current API the embedder has to extrenalize a string each
time a string is encountered to avoid the cost of repeated character
copying/conversion. The issue here is that the externalization cost
itself is non-negligible (both in time and space) and should not be
paid for a rarely used string. This change is an attempt to predict a
string's usage frequency based on its freshness. A string is
considered fresh if it was recently allocated in the new space.

dbe99e405a Introduce number type information in the virtual frame. 
Each frame element gets a new attribute with number type information. A frame element can be: 

- smi 
- heap number 
- number (i.e. either of the above) 
- or something else. 

The type information is propagated along with all virtual frame operations. 
Results popped from the frame carry the number information with them.

Two optimizations in the code generator make use of the new 
information: 
- GenericBinaryOpSyub omits map checks if input operands are numbers. 
- Boolean conversion for numbers: Emit inline code for converting a number (smi or heap number) to boolean. Do not emit call to ToBoolean stub in this case.

All two character string results from adding two strings and from sub string used to be handled in the runtime system as a lookup in the symbol table was done before allocating a new string. The native code for string add and sub string now probes the symbol cache for two character strings to avoid the runtime call. If the result string is not found in the symbol table within a fixed number of probes a new string is just allocated. Newly allocated two character strings are not added to the symbol table immediately.

4a2c81d3b0 Add last use data flow information to the fast code generator. 
This change add simple local live variable information to 
the fast code generator.  It supports only AST nodes that 
are accepted by the syntax checker.

Each variable use points to a variable definition structure
which contains the last use of the definition.

To determine whether a variable is live after a certain point
we can check whether its last use occurs later in the evaluation
order defined by the AST labeling number.

The new information is currently only printed out together with
the IR and not yet used for code generation.

9b5c312bfc Initial implementation of fast path operation for bitwise OR. 
Support a binary operation (bitwise OR) so long as it's not nested in
the left subexpression.  This ensures that the expression stack never
has height greater than two and so can be kept fully in registers.

The bounded expression stack height and the absence of any side
effects on the fast path allows us to still bailout out to the very
beginning of the function if any of our fast-path checks fail.

2f0f6face1 Fast compiler: Load globals variables directly from property cells. 
This is a first step towards loading globals directly from property cells instead
of going through a load IC.

This change supports only properties with the DontDelete attribute since
we are only able to bailout into the generic code generated by the secondary 
code generator the beginning of a function. The resulting fast-case code is 
specialized for a specific context. When invoked with a different global object, 
it will always bailout to the secondary code.

When loading a property that does not exist at compile-time or a property
that is deleteable we still generate the generic load IC.

This is the first step in the MIPS port of V8. It adds assembler, disassembler and simulator for the MIPS32 architecture.

Contains stubbed out implementation of all the compiler/code generator infrastructure to make it all build.

Patch by Alexandre Rames from Sigma Designs Inc.

This is the landing of http://codereview.chromium.org/543161.

a28143c77c Added extra tests to the DefineOrRedefineAccessorProperty and 
DefineOrRedefineDataProperty to avoid invalid input.

Added tests to object-define-property.js to test that it does not crash 
on invalid input.

4f179b09ba Added IsProperty() check to result in DefineOrRedefineAccessor - if no check 
this causes the debug check to fails since type() asserts that the 
lookup_type != NOT_FOUND. This does not change any functionality since we 
explicitly checked if it was one of the three types that we need to delete.
Also changed defineProperties in v8natives to actually return the object
being defined (as specified by spec)

f74a08d8ee Added Object.defineProperty + needed internal functionality: 
DefineOwnProperty (changed to allow for redefinition of existing property)
  SameValue
  Extra info on propertydescriptor
  GetProperty
  HasProperty

Currently the DefineOrRedefineAccessorProperty deletes the existing
property on the object if it is a dataproperty (FIELD or NORMAL) and
adds a new one. This can potentially be optimized.

10910394e6 Handle insertion order for simple constructors 
When functions only have simple assignments of the form this.x = ... the object is created in generated code without actually calling the constructor. In this case the initial map for the function already contains the properties assigned in the constructor. The field descriptors in this initial map now has an enumeration index assigned to make property enumeration order the insertion order. The insertion order here is the order of the this.x assignments in the code.

1. Avoid using SKIP_WRITE_BARRIER when we don't have to (smis).
  2. Check and document the remaining uses of SKIP_WRITE_BARRIER.
  3. Only allow GetWriteBarrierMode when in an AssertNoAllocation scope.

The only functional change should be in DeepCopyBoilerplate where we
no longer use the write barrier mode (because of allocations). I'm
running benchmarks to see if this has a measurable impact on performance.

9879490308 Implement SUB and BIT_NOT unary operations in full codegenerator. 
This change depends on landing the BIT_NOT unary op stub on arm. That
change is out for review.

25c6b59b1e Make sure to initialize all fields in the special maps 
created during bootstrapping. Without this change we 
risk having weird flags set on the map for the null
value (among others), which can lead to crashes.

eaa845804e Get it to compile when ENABLE_LOGGING_AND_PROFILING isn't defined. 
I think it currently is defined on all platforms except Android.

5fe8bd9919 Fix 64-bit build on Windows and Visual Studio project files 
64-bit version now builds on Windows again in both release and debug mode.

The Visual Studio project files have been updated so that all three configurations work (32-bit, 64-bit and 32-bit with ARM simulator). They all convert from Visual Studio 2005 to Visual Studio 2008.

80d71c6406 Changed JSObject::DefineGetterSetter to also set the right attributes 
when an existing accessor is redefined (a configurable accessor can
potentially be redefined as a non-configurable (i.e., DONT_DELETE)).
