bb2f8c038c The runtime function DeclareGlobals is not called from JavaScript.

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.

ee9d2d6cee Fast compiler support for regexp literals.
For .result = /abc.*/g we generate the following IA-32 code:

   ...
   mov ebx,[edi+0x17]
   mov eax,[ebx+0xb]
   cmp eax, 0xf5d0e135         ;; object: 0xf5d0e135 <undefined>
   jnz done
   push ebx
   push 0x2
   push 0xf5d13805             ;; object: 0xf5d13805 <String[5]: abc.*>
   push 0xf5d13815             ;; object: 0xf5d13815 <String[1]: g>
   call RuntimeStub_MaterializeRegExpLiteral
 done:
   push eax
   pop [ebp+0xf4]
   ...

This is very similar to the code previously generated except we do not 
generate deferred code for the case where we call the runtime.

On ARM we use the stm instruction to make pushing the arguments more compact.

9ee631338e Allow resource constraints to specify the max committed new space size
when using snapshots.

The alignment of new space has to match the alignment in the snapshot,
but the max committed amount of memory does not.

For now, we assume that the default semispace size is always used in a
snapshot.

46e6297e3e Added infrastructure for optimizing new CanvasArray types in WebGL
specification under development. The optimizations are patterned after
those previously done for CanvasPixelArray. This CL adds all of the
necessary framework but continues to use the generic KeyedLoadIC and
KeyedStoreIC code, to create a baseline for benchmarking purposes. The
next CL will add the optimized ICs to ic-ia32.cc and ic-x64.cc.

These new CanvasArray types have different semantics than
CanvasPixelArray; out-of-range values are clamped via C cast
semantics, which is cheaper than the clamping behavior specified by
CanvasPixelArray. Out-of-range indices raise exceptions instead of
being silently ignored.

As part of this work, pulled FloatingPointHelper::AllocateHeapNumber
up to MacroAssembler on ia32 and x64 platforms. Slightly refactored
KeyedLoadIC and KeyedStoreIC. Fixed encoding for fistp_d on x64 and
added a few more instructions that are needed for the new ICs. The
test cases in test-api.cc have been verified by hand to exercise all
of the generated code paths in the forthcoming specialized ICs.

4dfd44479d Added support for assignments to global variables in the toplevel code
generator.  We use the normal store IC mechanism with the global
object as the receiver.  The following code is generated for 'x=true'
at toplevel.

======== IA32:

27  mov eax,0xf5d06161          ;; object: 0xf5d06161 <true>
32  mov ecx,0xf5d09c35          ;; object: 0xf5d09c35 <String[1]: x>
37  push [esi+0x17]
40  call StoreIC_Initialize  (0xf5ce75c0)    ;; code: STORE_IC, UNINITIALIZED
45  mov [esp],eax

======== X64:

25  movq rax,0x7f867a7b6199    ;; object: 0x7f867a7b6199 <true>
35  movq rcx,0x7f867a7bae71    ;; object: 0x7f867a7bae71 <String[1]: x>
45  push [rsi+0x2f]
49  call StoreIC_Initialize  (0x7f8655929ac0)    ;; code: STORE_IC, UNINITIALIZED
54  movq [rsp],rax

======== ARM:

846688f825 Recognize in the fast-mode code generator when a subexpression is a
constant known at compile time.  Do not ever use the stack to
materialize (non-function-argument) constants.  Currently, constants
are only the non-materialized, non-function literals in the AST.

It is a known issue that there is no test coverage for the cases of
assigning a non-literal to a variable and returning a literal.  Those
code paths are unreachable and tests will be added when they become
reachable.

For the code '.result = true', we had previously on ia32:

27  push 0xf5c28161             ;; object: 0xf5c28161 <true>
32  pop [ebp+0xf4]

Now:

27  mov eax,0xf5c26161          ;; object: 0xf5c26161 <true>
32  mov [ebp+0xf4],eax

======== We had previously on x64:

25  movq r10,0x7fb8c2f78199    ;; object: 0x7fb8c2f78199 <true>
35  push r10
37  pop [rbp-0x18]

Now:

25  movq r10,0x7fb131386199    ;; object: 0x7fb131386199 <true>
35  movq [rbp-0x18],r10

The generated code for ARM did not include the extra memory traffic.
It was already eliminated by the ARM assembler's push/pop elimination.

0f5210e9dd Do not visit slots in the top-level code generator's backend.
Slots appear only indirectly in the AST (through variables linked to

putting compilation-time state on them is potentially a source of
bugs.  Avoid it for now.

339e49c0b2 Added first support for tracking locations of expressions in the
fast-mode code generator.

AST expression nodes are annotated with a location when doing the
initial syntactic check of the AST.  In the current implementation,
expression locations are 'temporary' (ie, allocated to the stack) or
'nowhere' (ie, the expression's value is not needed though it must be
evaluated for side effects).

For the assignment '.result = true' on IA32, we had before (with the
true value already on top of the stack):

32  mov eax,[esp]
35  mov [ebp+0xf4],eax
38  pop eax

Now:

32  pop [ebp+0xf4]


======== On x64, before:

37  movq rax,[rsp]
41  movq [rbp-0x18],rax
45  pop rax

Now:

37  pop [rbp-0x18]


======== On ARM, before (with the true value in register ip):

36  str ip, [sp, #-4]!
40  ldr ip, [sp, #+0]
44  str ip, [fp, #-12]
48  add sp, sp, #4

Now:

36  str ip, [fp, #-12]

2d6169bf7e Format the long lists of sources in the SConscript file to be one per
line.  This is to make it easier to add and remove sources without
having to reformat line breaks.  It also enables sorting with M-x
sort-lines (in emacs) or the like.

efb8cee324 Add initial semi-working producers profile.
Turned on with '--log-producers' flag, also needs '--noinline-new' (this is temporarily), '--log-code', '--log-gc'. Not all allocations are traced (I'm investigating.)

Stacks are stored using weak handles. Thus, when an object is collected, its allocation stack is deleted.

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)
22  call 0xf5cac960             ;; code: STUB, StackCheck, minor: 0
27  push 0xf5cca161             ;; object: 0xf5cca161 <true>
32  mov eax,[esp]
35  mov [ebp+0xf4],eax
38  pop eax
39  mov eax,[ebp+0xf4]
42  mov esp,ebp                 ;; js return
44  pop ebp
45  ret 0x4
48  mov eax,0xf5cca135          ;; object: 0xf5cca135 <undefined>
53  mov esp,ebp                 ;; js return
55  pop ebp
56  ret 0x4

1f8399bdda Partially revert r2761.
Do not create handles for values of internal fields---this operation is performance
critical and plain pointers are safe.

Appy the same approach to External wrapping and unwrapping.

Plus some minor refactorings.

a9880bde4d Skip access checks for hidden properties.
Hidden properties are used like internal fields which do not have
access checks. The checks can cause problems because there may be no
current context. See http://crbug.com/24200.
