8588518851 Introduce a stack-allocated structure to encapsulate compile-time information. 
Use it to hold the possible shared function info, the possible
receiver, and the compilation loop nesting depth.  Remove loop nesting
from FunctionLiteral AST nodes.

048fe9b980 RFC: Try to be much more careful with where we skip the write barrier by: 
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.

97e3aae5ef Refactoring and small optimization of the smi code for binary op stubs 
on ia32.

1. Operate on the values in edx,eax when possible (all operations
except DIV and MOD).  This saves moving them on entry and when falling
out to the non-smi code.

2. Do not perform ADD and SUB before the smi check of their inputs.
This saves undoing the operation in the case that we fall through to
the non-smi case due to non-smi inputs (probably common?), and we can
avoid emitting the smi check code twice (code size reduction).

3. Don't perform OR twice (once to smi check the inputs and once to
smi check the result).

cf78ed05ee Don't pass the "at start" parameter to native RegExp 
As the start index is already passed it is easy to calculate the "at start" boolean in generated code. Also as direct entry has been implemented this needs to be done in generated code anyway, and therefore might as well be moved to the generated code for RegExp. The "at start" value is now calcualted as a local variable on the native RegExp frame based on the value of the start index argument.

The x64 version have been tested on both Linux and 64-bit Windows Vista.

For ARM I have tested cctest/test-regexp on ARM hardware, but the rest of the tests have only been run on the ARM simulator.

36477ee160 Use registers to pass arguments to GenericBinaryOpStub. 
Currently arguments are never passed on registers (due to the way ArgsInRegistersSupported is written) and
if they were, the stub would break in several places because registers are not preserved properly in the
course of execution. This CL makes use of registers more often (than never) and makes sure that registers are
handler properly.
A peformance gain is small (0.2-0.3%) but stable.
This CL was extracted from the one sent out earlier (http://codereview.chromium.org/551093).

40fd97c87d A follow-up to fix 553: really report function object moves. 
As an afterthought, I realized that I put function objects moves
reporting into a method that deals with only code object moves.  I've
looked up that function objects are allocated in old pointer space and
new space, so I moved logging to the corresponding VM methods.

999e3fca90 Fix issue 553: function frame is skipped in profile when compare stub is called. 
The problem appeared due to a fact that stubs doesn't create a stack
frame, reusing the stack frame of the caller function. When building
stack traces, the current function is retrieved from PC, and its
callees are retrieved by traversing the stack backwards. Thus, for
stubs, the stub itself was discovered via PC, and then stub's caller's
caller was retrieved from stack.

To fix this problem, a pointer to JSFunction object is now captured
from the topmost stack frame, and is saved into stack trace log
record. Then a simple heuristics is applied whether a referred
function should be added to decoded stack, or not, to avoid reporting
the same function twice (from PC and from the pointer.)

d587851d7f Fix map compact implementation. 
Always invoke HeapObjectIterator::has_next() before invoking HeapObjectIterator::next().
This is necessary as ::has_next() has an important side-effect of going to the next
page when current page is exhausted.

And to find if pointers are encodable use more precise data---top of map space, not a number
of pages, as pages might stay in map space due to chunking.

37d3972429 Fix issue 571: display descriptive names for code objects from snapshot. 
As this is only needed for internal profiling (not for DevTools),
the following approach had been chosen:

 - during snapshot creation, positions of serialized objects inside
   a snapshot are logged;

 - then during V8 initialization, positions of deserealized objects
   are logged;

 - those positions are used for retrieving code objects names from
   snapshot creation log, which needs to be supplied to tick processor
   script.

Positions logging is controlled with the new flag: --log_snapshot_positions.
This flag is turned off by default, and this adds no startup penalty.

To plug this fix to Golem, the following actions are needed:

 - logs created using 'mksnapshot' need to be stored along with VM images;

 - tick processor script needs to be run with '--snapshot-log=...' cmdline
   argument.

562f90d375 Ensure correct boxing of values when calling functions on them 
When a function is called with a value type as the receiver this is now boxed as an object.

This is a low-impact solution where the receiver is only boxed when required. For IC calls to the V8 builtins values are not boxed and as most of the functions on String.prototype, Number.prototype and Boolean.prototype are sitting there most IC calls on values will not need any boxing of the receiver.

For calls which are not IC calls but calls through the CallFunctionStub a flag is used to determine whether the receiver might be a value and only when that is the case will the receiver be boxed.

No changtes to Function.call and Function.apply - they already boxed values. According to the ES5 spec the receiver should not be boxed for these functions, but current browsers have not adopted that change yet.

1cc579ff4e Fix issue 541 and some refactoring of the top-level compiler. 
* Refactor VisitProperty to use the platform-specific methods for emitting the IC calls.
* Refactor recording of source positions in the top-level compiler.
* Correct the recorded source positions for assignments and property loads.
* Fix bug on x64 where source positions were not recorded before a calling a call-IC.
* Correct some inconsistencies between IA-32 and X64 top-level code generator.

We now pass all regression tests with 
--always-fast-compiler.

acf74b04a7 Fix a problem when compiling built-ins with the top-level compiler. 
Replace runtime call to NumberAdd with call to binary op stub.

Until now the top-level compiler always called a runtime function
for count operations. 

In some places we expected in the JS builtins smis as arguments.
If we perform a count operation before all smis would get converted into
heap numbers by the runtime number add function and result in a runtime 
assert.

Also: Add missing debugger information in the top-level compiler for 
do-while loops.

  was 'Move', now it's 'Apply' so as to avoid confusion with various
  other Moves (eg, in the toplevel codegen, in the macro assemblers).

* Use the abstraction Drop rather than math on the stack pointer.

* Add a predicate on AST expression nodes to abstract a repeated test
  whether we should us a regular (named) IC or a keyed IC.

Instead of going through a runtime function for keyed loads
on strings we invoke a separate specialized stub that
assumes string as receiver type and the key to be a number.

The stub calls a JS builtin function to return the corresponding one-character string.

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.

b74ab45077 Simplify checking during allocation when Heap::always_allocate() is 
true.  The rules are:

1. Heap::AllocateRaw can normally handle allocation requests in new
   space even when always_allocate() is true.  It properly retries
   failed allocation in the second 'retry' space.

2. Heap::Allocate can normally handle allocation requests in new
   space.

3. We only need to check always_allocate() when explicitly requesting
   allocation in new space via Heap::new_space().AllocateRaw().

4. The exception to these rules is fixed arrays with size such that
   MaxObjectSizeInPagedSpace < size <= MaxObjectSizeInNewSpace (ie,
   those that will be allocated in new space and promoted to large
   object space).  They cannot be allocated in new space via
   Heap::Allocate or Heap::AllocateRaw, because the retry logic does
   not know to allocate extra remembered set bits when retrying in
   large object space.

0553c7feb9 Optimize bitops with non-Smi inputs. Instead of converting both inputs 
to floating point and then converting back we convert directly to a
32 bit integer.  In addition the bit twiddling implementation of float-
to-integer conversion has been ported from ARM.  Testing has shown that
this runs faster than the x87 or SSE3 rounding instructions.  This change
is IA32 only.  There may be a smaller benefit from doing the same on x64.

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).

0672938b88 Fix a crash caused by garbage collection during generation of a 
callback load (or keyed load) IC.

The problem was that the IC code calls a stub, which can allocate and
thus trigger a GC if the stub is not already generated.  Problem is
solved by adding the ability to "try" to call a stub, trying to
generate the stub code if necessary but signaling an allocation
failure if generating the code is not possible.

7a3a043eb2 Refactor code for generating assignments in the fast compiler. 
1. Refactor the structure of VisitAssignment: The existing code is not ideal 
to be extended with support for compound assignments.

2. Reuse common code for keyed property assigments: Now variables rewritten 
to a property (.arguments access) are treated like normal keyed property
assignments. This allows us to remove some code duplication.

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.

fc713930ed Remove the last context dependent reference from the Script object 
For scripts originating from a call to eval the Script object used to hold a reference to the function from where the eval was called together with the code offset within that function of the eval call. This is used by the stack trace and is part of the debugger protocol. In order to avoid storing the function the script, the position within the script and the name of the function calling eval is stored instead. This avoids holding context dependent objects in the script object.

The calculation of the position of the eval in the script holding the eval is now done when the eval script is compiled as it is not possible to postpone this unless a reference is kept to the generated code for the function calling eval.

eb4d261e24 Remove the different length string types 
The different length string types was used to encode the string length and the hash in one field. This is now split into two fields one for length and one for hash. The hash field still encodes the array index of the string if it has one. If an array index is encoded in the hash field the string length is added to the top bits of the hash field to avoid a hash value of zero.

On 32-bit this causes an additional 4 bytes to be used for all string objects. On 64-bit this will be half on average dur to pointer alignment.

Callback entry address is stored in VMState and is later retrieved by
profiler stack sampler. This makes possible relating API entry to JS

This is needed to show calls to DOM in CPU profiles. I can think
of a better approach like adding specific functions into V8 API
for explicitly providing callback names and modifying bindings codegen
appropriately. My plan is as follows:
 - submit this CL;
 - implement anything I need to process log data and display DOM
   calls in profiles;
 - think again about adding specific functions and modifying bindings
   codegen.

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.

53bee811ad Re-enable using push instructions for syncing the virtual frame. 
This change fixes the problem with the original version of this approach
(r3032) that may lead to a corrupted stack if we would invoke spilling during 
syncing a large SMI constant (unsafe SMIs) in the virtual frame.

The new code for storing unsafe SMI constants does not use an extra temporary 
register. This prevents the compiler from ever having to spill during a 
virutal frame sync operation.

For storing a large SMI constant we previously generated:

  mov ecx, (large_smi & 0x0000ffff)
  xor ecx, (large_smi & 0xffff0000)
  push ecx

we now generate:

  push (large_smi & 0x0000ffff)
  or   [esp], (large_smi & 0xffff0000)

Not using a temporary register avoids spilling within an nvocation 
of VirtualFrame::SyncRange.

This change re-allows non-lazy compiled function literals for top-level compilation.

There was a problem on ARM exposed through this change which was fixed as part of r3289
in fast-codegen-arm.cc (Threading and Threading2 tests failed)

It occurred before r3289 when we allocate a local context at the beginning of a function. The
code for the stack check was split up in an unintended way (load of stack check limit into r2, 
and use of r2 in the actual stack check code).

d53f05e3e2 Fix warnings on Win64. 
Set warning level to /W3 and change implicit conversions from size_t
to int. Most "fixes" are simply manifesting the implicit casts or using
a special strlen replacement that returns int.

cd9660f77c All hidden properties of an object are stored in a value of a regular property with empty name. This property may confuse user if returned among regular properties. It should not be exposed directly by ObjectMirror. Should we want an access to these properties from debugger we need to implement an explicit method for that. 
Current patch filters the hidden_symbol from property names returned to ObjectMirror.

963d72ff57 Revert r3032 that uses push instead of 'sub esp, size'. This change 
leads to stack corruption in 32-bit version of V8.

See http://code.google.com/p/chromium/issues/detail?id=27227 for a
reproducible case.

Since this is only an issue on 32-bit V8 I think this has got
something to do with the UnsafeSmi handling that we do on ia32.  I'm
reverting for now so we can push a fix, but we should track down the
issue and create a regression test for this.

091c7a2306 Fixed bug in while-loops that caused an assertion to fail. 
We forgot resetting true-/false-label to NULL after evaluating the 
condition expression in dowhile- and while-loops. 
This change fixes this.

This causes an assertion to fail in VisitIfStatement whenever there is an 
if-statement after a while-loop before. e.g. like in:

  var i=0, j=0;
  while(j<5) { j++; }
  if (i ==0 ) { j++; }

b068a9f755 * Fix regexp benchmark regression where we were doing work to 
make standard regexps like \s and . case independent.
* Make use of the fact that the subject string is ASCII only
when making character classes case independent.
* Avoid spending time making large ideogram or punctuation
ranges case independent when there is no case mapping anyway.

6a3921fc0e Keep natives source code in external strings instead of putting 
it in regular flat strings that are part of the snapshot.
After this change we don't need libraries-empty.cc any more.  In
this change libraries-empty.cc is just a the same as libraries.cc
and the scons build builds it but does not use it.  We can move
in stages to a situation where it is not generated at all for all
the build systems that we have.
