a609cf61c5 Avoid decoding overhead when allocating ascii strings. 
The assumption is that most utf8 strings allocated are actually ascii
and that if they are not we will encounter a non-ascii char pretty

It is a precondition of HEnvironment::Lookup(variable) that variable is

e21d76a0e3 1. Added support for object printing for release mode using the 
objectprint=on (defaults to off) option (which defines OBJECT_PRINT).
2. Added the ability to print objects to a specified file instead of
   just stdout.
3. Added a use_verbose_printer flag (true by default) to allow some
   object printouts to be less verbose when the flag is false.
4. Fixed a bug in VSNPrintF() where it can potentially write into an
   empty char vector.

6cc0310a72 Mark map-transition stores as map-changing instructions. 
This prevents code motion from hoisting map-checks across such stores
which may result in unnecessary deoptimizations.

In the following example program we would move a map-check from the inner loop out before the outer loop which is not desirable:

function f() {
  var o = {};
  var j = 0;
  o.a = 1;
  do {
    o.b = 6;  // Map transition
    for (var i=0; i<10; i++) {
       o.a = o.b + i;
    }
  } while(++j < 1) {}
}

for (var i = 0; i < 1000000; i++) f();

4a6ef3ee28 Fix issue 977, occasional failure of the DeltaBlue benchmark. 
Before, when we deoptimized after a branch we jumped to before the branch
was taken in the unoptimized code with a token value that indicated when
edge to take.  There was a lot of machinery to track this value through the
short-circuit logical operations and logical negation, and to handle it
properly at inline function return sites.  There was also machinery to
prevent incorrectly seeing this environment with the extra value never
actually materialized in the unoptimized code.

Instead, now we deoptimize directly to one of the targets of the branch.
Much but not yet all of the extra machinery has been removed or simplified.
The cost is that branching control structures (the looping statements, if
statements, conditional expressions, and the short-circuit binary logical
operations) need extra AST IDs to identify the branch targets.

357afa385b Change Object.defineProperty to accept undefined as getters and setters and to correctly accept overriding an accessor with a data property. 
In the past we only accepted functions as argument for setting an
accessor. Since one should be able to set an accessor to undefined
this had to be changed to take either.

In addition, we did not lookup properties in the prototype chain,
causing us to call the setter of an existing accessor up the prototype
chain when trying to replace an existing accessor (that was not local)
with a data property.

ace6290452 Fix issue 974. 
When entering a finally block in unoptimized code, we unconditionally
save the accumulator register in the stack in case it holds a return
value or an exception.  In the case of a break, continue, or falling
off the end of the try or catch block, this value is unpredictable and
not necessarily safe for GC.

b93a0f5d9a Second attempt: Improve our type feedback by recogizining never-executed IC calls for binary operations. 
This is an improved version of my earlier change r5970. It avoids degrading the
non-optimized code.

Initially we emit a conditional branch that is either always- or never-taken
after a smi-check (depending on whether we test for smi for for non-smi)
Since test-eax always sets the carry-flag to 0 we use jump-if-carry and
jump-if-not-carry.

The first invocation of the stub patches a jc with a jz and
jnc with a jnz-instruction so that the code looks exactly as it was
without patching. The only difference is the test- or nop-instruction
after the IC-call.

49f4c39d6d Deoptimize to the proper target after assignment side effects. 
This fixes V8 issue 989.

Before, assignments used the AST ID of the assignment expression to
mark the side effect of the store, which became a target for
deoptimization bailout for code after the assignment.  In effect
contexts this environment included the value of the assignment, which
was unexpected by the unoptimized code.

Now we introduce a new assignment ID for AST node types that include
an assignment (Assignment, CountOperation, and ForInStatement) and use
it for the side effect of the store.

b16df72475 Improve our type feedback by recogizining never-executed IC calls for binary operations. 
In the case of inlined smi code in non-optimzied code we could not 
distinguish between the smi-only case and the case that the operation was
never executed.

With this change the first execution of a binary operation always jumps
to the stub which in turn patches the smi-check into the correct
conditional branch, so that we benefit from inlined smi code after the
first invocation.

A nop instruction after the call to the BinaryOpIC indicates that no
smi code was inlined. A "test eax" instruction says that there was smi
code inlined and encodes the delta to the patch site and the condition
code of the branch at the patch site to restore the original jump.

48d884de48 ARM: Fix heap number allocation in lithium-codegen-arm that assumed 
that ip can be used as a scratch register. This is not true because
ip is already used for something else in AllocateInNewSpace in the
macro assembler.

Explicitly allocate a temp register for use in the heap number
allocation instead.

e0d3f6afdf Be more careful about exiting inlined functions in a test context. 
When falling off the end of a function inlined in a test context, we cannot
constant fold the test of undefined away. The graph builder assumes that
control flow always reaches both branches of a test.

Instead, explicitly test and branch on "undefined". Introduce a pair of
empty blocks to hold the necessary LeaveInlined instructions.

7be18f702b make DateParser::TimeComposer handle 1-2 digits millisecond values 
see http://code.google.com/p/v8/issues/detail?id=944
This patch makes DateParser::TimeComposer process times that have
millisecond values with only 1 or 2 digits.

Without this patch, Date.parse("2010-11-25T22:02:30.5") returns
1290690150005 and
Date.parse("2010-11-25T22:02:30.5") == Date.parse("2010-11-25T22:02:30.005")
evaluates to true.

With this patch, Date.parse("2010-11-25T22:02:30.5") returns
1290690150500 instead, and
Date.parse("2010-11-25T22:02:30.5") == Date.parse("2010-11-25T22:02:30.005")
evaluates to false.

be0f740d99 Landing for Justin Schuh. 
Seed the random number generator in Windows with rand_s 

This is a quick fix for m9. It works on Windows Chrome because the random device is already initialized before permissions are dropped for the Chrome sandbox. The same trick isn't possible on Linux or Mac. 

I think the long-term solution is to provide an interface for supplying v8 with a true random number generator. Then Chrome can just hook up the generator from base/rand_util.h

4c6f79ecec Fix crashes during GC caused by partially initialized objects. The 
inline allocation code used the expected number of properties to
calculate the number of inobject properties for an object instead of
getting the actual number from the initial map.

It is safer to use the inobject property count from the initial map in
any case because that is the amount the instances will get. I think
this disconnect got introduced when adding shrinking of objects.

Unfortuntely I haven't been able to create a simple reproduction for a
test case but this fixes the webpage that exhibits the crash. I'll see
if I can create a reproduction tomorrow.

Otherwise, retaned memory sizes are not precise. This increases size
of heap snapshot, I will deal with this later. Heap objects and
references previously missing in snapshot are now marked as 'hidden'.
That means, they not shown to user, but participate in sizes
calculation.

Other small changes:
 - added 'shortcut' graph edges: e.g. to pin global objects on top
   level;
 - meta-information in JSON snapshot is no more double encoded.

2a8eb35548 Provide more accurate results about used heap size via GetHeapStatistics. 
I observed that used heap size provided by Heap::SizeOfObjects() is
usually about ~10% bigger than the number calculated by summing up
heap objects sizes.

This aligns DevTools Timeline stats with Heap profiler stats.

Currently weak handles retain an object for another GC round (oftem times,
major GC round.)  Instrumenting Chromium shows that navigation leaves
many global objects which are only collected in next go.  Let's
attempt to collect more garbage when approacing OOM condition.

This is a better version of rolled out r5455: now it's correctly
rebuilds object groups between additional GCs.

ef06d71229 Landing for Rodolph Perfetta. 
Improve V8 VFPv3 runtime detection, to address issue 914.

This patch will check for the exact word vfpv3 as well as 0xc08 (CortexA8
part number) as some earlier kernel didn't report vfpv3 for A8.
