788c5e344d Better align heap snapshots contents with debugger info. 
I created a heap snapshot in Chromium, and then started comparing
it side-by-side with representations of objects provided by
the debugger, fixing discrepancies.

If there are few non-zero digits and the 10^exponent fits into a double then
we can compute the result using 1 (or 2) double operations.

7c238db829 Do not shortcut union of keys if lhs is empty. 
The problem is other array may have holes, for example
when fixed array comes from JSArray (in case of named interceptor).

If that would prove to be a performance problem, we could
pass an additional argument into UnionOfKeys to hold actual length.

5a30072502 Fix HeapSnapshotsDiff test, diff implementation, and a bug introduced 
during snapshot size optimization.

Sorry, now I figured out that the diff implementation itself was also
incorrect.  Reachable nodes must be filtered from the beginning,
otherwise, an object that is already disconnected, but not discarded
yet, will not appear as a deleted (thankfully, this bug for some
reason had appeared on the x64 port.)

2005 so I hope it also passes the 2008 version.

The --max-new-space-size option is now in kBytes.
The --max-old-space-size option is now in MBytes.

cfbc1eed9c Prevent modification of cached normalized maps. 
Finally sovles the problem that r5342 attempted to solve.
When adding a stub to a map's code cache we need to make
sure that this map is not used by object that do not need
this stub.

Existing solution had 2 flaws:
1. It checked that the map is cached by asking the current context.
If the object escaped into another context then NormalizedMapCache::Contains
returns false negative.

2. If a map gets evicted from the cache we should not try to modify it
even though Contains returns false.

This patch implements much less fragile solution of the same problem:
A map now has a flag (is_shared) that is set once the map is added
to a cache, stays set even after the cache eviction, and is cleared
if the object goes back to fast mode.

Added a regression test.

06c867404b Dynamically determine optimal instance size. 
The number of inobject properties used to be derived from the number
of this property assignments in the constructor (and increased by 2 to
allow for properties added later). This very often leads to wasted inobject 
slots.

This patch reclaims some of the unused inobject space by the following method:
 - for each constructor function the first several objects are allocated using the initial 
   ("generous) instance size estimation (this is called 'tracking phase').
 - during the tracking phase map transitions are tracked and actual property counts are collected.
 - at the end of the tracking phase instance sizes in the maps are decreased if necessary
   (starting with the function's initial map and traversing the transition tree).
 - all further allocation use more realistic instance size estimation.

Shrinking generously allocated objects without costly heap traversal is made possible 
by initializing their inobject properties with one_pointer_filler_map (instead of undefined). 

The initial slack for the generous allocation is increased from 2 to 6 which really helps some tests.

c1903ce332 Show RegExp calls in the profile. 
It turns out they were filtered out. But when I unfiltered them, I
discovered another issue: when DevTools run, regexp literals get
recompiled each time they called (looks like this is concerned with
switching to full compiler), so I ended up having multiple entries for
the same regexp. To fix this, I changed the way of how code entries
equivalence is considered.

2388079051 Implement heap snapshots serialization into JSON. API is designed 
to avoid storing serialized snapshot on VM, instead it is emitted
using output stream interface.

The size of JSON emitted is roughly equal to used heap size
(when stored as an ASCII string).

Now a whole heap snapshot can be serialized and transmitted outside
VM. This makes possible:
  - implementing non-async UI for heap snapshots inspection;
  - storing heap snapshots for further inspection;
  - remote profiling (we can even implement a snapshotting mode
    where a snapshot isn't even stored in VM, only transmitted --
    good for mobile devices);
  - creating tools for outside heap snapshots processing, e.g.
    converting to HPROF.

This makes, e.g., Date.parse("2010-08-31T22:35:36-09:00") work as
expected. Without this change, the "-9:00" timezone-offset portion
causes V8 to fail to properly parse that string into a date.

be5763fc4d Cleanup the way the debugger stores live registers when entering at a break 
The live registers are now only stored to the expression stack with the non pointer values being stored as smis (on the 32-bit platforms these values are assumed to be 31-bit max).

This makes the CEntryStub entry/exit code much simpler, and there is no longer any need for a mode (debug or normal) on it.

Fix a missing live register when breaking at ARM keyed load.

7672338bc9 Fixes bug in Object.freeze and Object.seal causing them to misbehave when Array.prototype has changed. 
Object.freeze and Object.seal uses GetOwnPropertyNames which
returns an array with local property names. This array will also have
the additional properties defined on Array.prototype or
Object.prototype.

Note that, the implementation of GetOwnPropertyNames (when used as
Object.getOwnPropertyNames) is correct, since the spec says to create
a new Array (which would also have these properties).

8e0cd6db8a Handle overwriting valueOf on String objects correctly when adding 
This adds a check to the fast case string add to ensure that the String object still have the default valueOf function. The default valueOf is sitting on a hidden prototype of String.prototype.

Before using the fast case valueOf the object is checked for a local valueOf property. For slow case objects this check always reports true (the dictionary is not probed, so valueOf might be there) and for fast case objects the descriptor array is checked for the valueOf symbol (just liniar scan). After that the prototype is checked for beeing the initial value of String.prototype. If this all pass (that is the default valueOf is still in place) this result is cached on the map making the check fast the next time.

This is only implemented in the optimizing compiler, as the two usages of %_IsStringWrapperSafeForDefaultValueOf is never hit by the full compiler.

I will port to x64 and ARM when this has been reviewed for ia32.

I will remove the performance counters prior to final commit.

57769489d5 First phase of migration to new indexed property query callbacks. 
Eventually indexed property query callbacks will return attributes
(as an integer) or an empty handle if property is not intercepted.

To gradually migrate to this new API, USE_NEW_QUERY_CALLBACK
macro would control if old or new style API is used.

So the migration plan is:

1) introduce new API which should be explictily enabled;
2) switch to new API defining USE_NEW_QUERY_CALLBACK before
include of <v8.h> (that would require changes to client code as well)
3) remove old API from v8
4) remove #define USE_NEW_QUERY_CALLBACK from clients.

c98ac6e82c Heap profiler: implement diffing of snapshots. 
To trace objects between snapshots, an external map of object tags is
maintained. After the first heap snapshot has been taken, the map is
updated by reporting object moves from the GC. If no snapshots were
taken, there is no overhead (except for flag checking).

I considered graph comparison algorithms that doesn't require using
object tags, but they are all of a high computational complexity, and
will still fail to detect object moves properly, even for trivial
cases, so using tags looks like unavoidable.

118a421067 Simplify the transitions in the Binary Op ICs. Now a single call 
to the runtime will both patch in the more specialized binary op
stub and calculate the answer.  This eliminates the need to call
both the rest of the binary op and the patching runtime call.  The
runtime routines are altered to be more agressive in returning
Smis so we don't get spurious heap numbers as inputs to binary ops
while we are patching the binary op ICs.

expectations.

We are currently using a rather old version of the ES5 conformance
tests and there has been a range of bug fixes in the test set. This
change brings us up to date. 

In addition, our current test expectations discards the all chapters
but chapter 15. I have enabled the other chapters, cleaned up the
tests that we no longer fail on, and filed bugs for tests that we fail on.

It seems some of the bugs on the es5 conformance bug-tracker has been
fixed but not marked fixed. I will file bugs for the newly discovered
test bugs.

code and in runtime functions.

This also fixes a bug in GetOwnProperty in runtime.cc discovered by
the new test cases. That part of the code was not testable before
since we had no way of correctly defining properties on elements.

e045ca6898 Better handling of stepping out of a function 
With the change in r4820 all return statements are now breakable like any statement, so stepping will stop before the return statement actually returning from a function. With this change the position when breaking in the function return (after executing the return statement) will be the actual end of the function. At this point the return value is available as it saved to the stack by the debug break at return handling. Added information on the actual value returned from the function to the debugger.

634fb9152c More precise break points and stepping when debugging 
Added support for more precise break points when debugging and stepping. To achieve that additional nop instructions are inserted where breaking would otherwise be impossible. The number of nop instructions inserted are sufficient to make place for patching with a call to a debug break code stub. On Intel that is 5 nop's for 32-bit and 13 for 64-bit. Om ARM 3 nop instructions (12 bytes) are required.

In order to avoid inserting nop's in to many places a simple ast checker have been added to check whether there are breakable code in a statement or expression. If it is possible to break in an expression no additional break enabeling code is inserted.

Added break locations to the true and false part of a conditional expression.

Added stepping tests to cover more constructs.

These changes are only in the full compiler.

Changed the default value for the option --debugger in teh d8 shell from true to false. The reason for this is that with --debugger turned on the full compiler will be used for all code in when running d8, which can be unexpeceted.

e0bbcf1e6e Fix bug in mjsunit/const-eval-init causing objects to be initialized to undefined. 
In mjsunit/const-eval-init - testInitSlowCaseExtension a range of objects are initialized to undefined instead of a value because the variable i is within quotes (i.e., the source becommes "a1 = i" instead of "a1 = 1".

This should have no impact on the test, I just stumbled over this on
an unrelated matter.
