dd7b55eb9f Implemented one-char cache lookup in generated code.
This speeds up string,charAt(n) and string[n].

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.

893637a057 Inlining a few virtual frame functions.
Introducing a virtual-frame-inl.h file containing some platform-independent
virtual frame function which are small enough to be inlined.

Removed unnecessary #include of virtual-frame.h from register-allocator-inl.h
and added the necessary explicit includes in a number of files.

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.

6093d0dbf5 Inline NumberToString
NumberToString in runtime JavaScript is inlined through a call to a stub. Currently the stub only checks the number string cache and only if the number is a smi. Code is shared with the inlining of number string cache lookup when adding a smi to a string.

638cb4f91d Always load the JavaScript builtins code entry from the JavaScript
function instead of baking in the address of the first one that we see
in code.

This removes the need for fixups processing and makes the stubs safe
when there is no natives cache and therefore multiple versions of the
builtin functions.

3d36c712aa Use generated code to create sub strings.
Added a stub to allocate and fill a string object with a substring from another string.

Use the rep movs instruction to copy the string data as it turned out to be the fastest way.

While preparing this I experimented with some SSE2 instructions, so the instructions movdqa and movdqu are still in the IA-32 assembler even though they are not used.

429f3cf9f2 Direct call to native RegExp code from JavaScript.
Calls to RegExp no longer have to be via a call to the runtime system. A new stub have been added which can handle this call in generated code. The stub checks all the parameters and creates RegExp entry frame in the same way as it is created by the runtime system. Bailout to the runtime system is done whenever an uncommon situation is encountered or when the static data used is not initialized. After running the native RegExp code the last match info is updated like in the runtime system.

Currently only ASCII strings are handled.

Added another argument to the RegExp entry frame. It indicated whether the call is direct from JavaScript code or through the runtime system. This information is used when RegExp execution is interrupted. If an interruption happens when RegExp code is called directly a retry is issued causing the interruption to be handled via the runtime system. The reason for this is that the direct call to RegExp code does not support garbage collection.

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.

d9d18b30f5 Implement IS_OBJECT and IS_FUNCTION as inlined runtime functions.
Summary:
This change fixes a performance regression introduced by the special
handling of regular expressions in typeof expressions.
As a result we regain ~8% speedup on 3d-raytrace and ~13% on boyer
(vs bleeding edge)

Description:
The macros IS_OBJECT and IS_FUNCTION are frequently used in the 
JS runtime functions. 
By introducing new inlined runtime functions %_IsFunction and %_IsObject
we avoid invoking the more expensive %_ClassOf function plus comparing
its result to a string.

The choice is guarded by a test that the function is anonymous (thus

A compilation hint is set in the shared function info and used to make
the choice.

f74e723599 Initial infrastructure for fast compilation of top-level code. The
fast code generator is optimized for compilation time and code size.

Currently it is only implemented on IA32.  It is potentially triggered
for any code in the global scope (including code eval'd in the global
scope).  It performs a syntactic check and chooses to compile in fast
mode if the AST contains only supported constructs and matches some
other constraints.

Initially supported constructs are

* ExpressionStatement,
* ReturnStatement,
* VariableProxy (variable references) to parameters and
    stack-allocated locals,
* Assignment with lhs a parameter or stack-allocated local, and
* Literal

This allows compilation of literals at the top level and not much
else.

All intermediate values are allocated to temporaries and the stack is
used for all temporaries.  The extra memory traffic is a known issue.

The code generated for 'true' is:

 0  push ebp
 1  mov ebp,esp
 3  push esi
 4  push edi
 5  push 0xf5cca135             ;; object: 0xf5cca135 <undefined>
10  cmp esp,[0x8277efc]
16  jnc 27  (0xf5cbbb1b)

27  push 0xf5cca161             ;; object: 0xf5cca161 <true>

586f94f292 Split the AST LoopStatement type into separate types for do/while,
while, and for loops.

Previously they were distinguished by a type field, which required
runtime asserts to avoid invalid nodes (since not all loop types have
the same internal structure).  Now they C++ type system is used to
require well-formed loop ASTs.

Because they do not share compilation code, we had very large
functions in the code generators that merely did a runtime dispatch to
a specific implementation based on the type.

f0ba671344 Move the per-ast-node statement position to only statement node types.
It was not currently being used for expressions or declarations and
always had the default initial value.

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.

a48fd5916e Change the overly-general class named Node to the more specific
AstNode in case we ever want to have some other kind of node.

Split the NODE_LIST macro-generating macro so that we can iterate
concrete subclasses of Statement and concrete subclasses of Expression
separately.
