The state here should be NO_REGISTERS.  It was spuriously changed to from
NO_REGISTERS to TOS_REG when TOS_EAX was renamed to TOS_REG.

20f2c1c98a Make sure that we do not call is_extensible on the global proxy. 
When calling Object.isExtensible we did not do a check for the global
js proxy. This caused the check on the extensible bit on the map to
return true, even when the bit was set to false on the global js
object.

52cfd6ab16 Fixed a number of issues on x64 crankshaft port: 
- Don't use SmiSub when overflow can occur. It asserts that overflow
  does not happen.

- Actually use CompareICs and signal to crankshaft whether or not smi
  code was inlined.

- Fix bug in CmpI where 64 bits were compared instead of 32 bits.

- Implement Throw, DeferredStackCheck, StoreKeyedFastElement in
  lithium backend.

Revision 6635 added an assert on IA32 that there were no 'const' parameters.
This assert could be hit at compile time because we compiled the unreachable
body of functions with illegal redeclarations, which are thrown at runtime.

17da434b29 Remove instruction summaries. 
Instead of constructing a temporary container for all LOperands of each
instruction, the register works directly on the LIR instructions that
 provide an abstract interface for input/output/temp operands.

This saves allocation of zone memory and speeds up LIR construction,
but makes iterating over all uses in the register allocator slightly
more expensive because environment uses are stored in a linked list of
environments. We can fix this by using a flat representation of LOperands.

32cd13ebf1 Remove the redundant load on every context lookup. 
There was an unnecessary load on every statically-resolved context lookup.
Remove it.

This revealed a hidden bug in const initializers inside 'with'.  They claim
to be statically resolved (having slot type CONTEXT) but they occur in a
spot where the runtime context chain and the static scope chain do not
agree.  This is fixed by special casing const initializers in the backend.

97ccdd1e99 Introduce a hydrogen value for contexts, support context slot assignment. 
Each context in the context chain has a corresponding hydrogen value.
The context values are used for global object lookup and context slot
lookup.  Add simple (non-compound) assignment to context slots.

2d9c65901b Heap profiler: fix removed DOM wrappers reporting. 
Aggregated snapshots: don't report unreachable objects.
Full snapshots: restore forcing GC prior to taking a snapshot.

I played with the repro page provided for the bug and found that GC
must be performed prior to taking a snapshot even if we only report
reachable objects. GC allows weak handles to finalize.  Now heap
profiler produces aligned results for the repro page in both modes.

fed5622671 Better security checks when accessing named properties via Object.getOwnPropertyDescriptor. 
Current approach returns undefined descriptor if caller is not granted v8::HAS_ACCESS.
If the caller has v8::HAS_ACCESS, for no JS accessors regular v8::GET_ACCESS check is
performed and value property of the descriptor is set to undefined if caller doesn't
have proper access.  For JS accessors both v8::GET_ACCESS and v8::SET_ACCESS are checked
and affect if getter and setter would be stored in the descriptor.

f1149734fc Partial fix for V8 issue 1079. 
Record a safepoint with a deoptimization id for throw in optimized code.  We
don't seem to much care what the AST ID is because we will not be using it
for lazy deoptimization (throw doesn't return to the point of throw).  For
hygiene we use the actual ID of the throw expression.  Throw is no longer a
control-flow instruction, but it's followed by an unconditional abnormal
exit.  This is required to insert a simulate between the throw and the exit.

Make our optimized treatment of Function.prototype.apply act like a call and
have side effects.  This ensures that it will get a lazy deoptimization
environment.  Use that deoptimization ID in the safepoint for the call.

Deleting a property was also missing a deoptimization ID, though there was a
deoptimization environment assigned to the instruction.  Record the
environment and use the deoptimization ID at the safepoint.

cb0a7bc748 This fixes the issue with the deoptimizer trashing the reloc info before patching the code. 
If we, immediately after the deoptimization, but before actually
running the patched code, get a compacting GC, the addresses from the
calls might no longer be valid.

I have validated that this works by patching the existing code to
always do a compacting gc after we finish deoptimizing. I will create
a real regression test for this, but this includes additional code for
allowing us to force a deopt/opt from javascript test code. I will
land this in a seperate change.

f8b74a1541 Avoid using Function.prototype.call in a number of places in our 
builtins files. We should always use %_CallFunction for a couple of
reasons: it cannot be overwritten and it does not wrap basic types in
wrapper objects.

dc61921bbf Fix reintroduction of global variables that have been deleted. 
Deletion of global properties puts 'the hole' in the global property
cell and updates the property details in the property dictionary with
the information that the property has been deleted. When setting
global properties that have been deleted in generated code we just
store the new value in the global property cell. This does not update
the property details in the property dictionary. Therefore, it looks
like the property is not there eventhough it was just reintroduced.

Perform 'the hole' checks in generated code for global property stores
and bail out of ICs and optimized code if storing to a property cell
that contains 'the hole'.

The remaining variants of LCodeGen::RecordSafepoint remain as a convinient way to record common safepoint kinds.

c1bbd04dce Remove the HInstruction utilities taking flag mask arguments. 
It is a type error to treat a flag (an enum) as if it were a flag mask (an
int derived from shifting a bit by the enum value).  It is error prone to
have functions that take flag mask arguments because they will silently
accept flags.

331b482332 Fix bug 1070: set correct holder for primitive checks. 
Code generated for checks starting with primitive receivers skips one step
in the usual prototype checking algorithm, so the holder must always be set.

Not setting the holder did not cause an immediate failure because our
primitives have additional hidden prototypes before the real prototypes.
These extra objects in the chain usually contain no properties and so
allowed the right holders to be selected.

d69ef26f7d Another fix for leaking error objects. User code can overwrite 
ReferenceError.prototype.__proto__ which will make "error instanceof
Error" fail. However, the ReferenceError.prototype object itself
cannot be modified. Therefore, the error checks must check for
concrete error instances instead of only checking for Error.

161d631b5e Change ARM exit frame layout and alingment handling 
Change the ARM exit frame to have the same layout as the IA32 exit frame. This basically re-arranges the order of fp and sp and changes the sp location of the entry frame to hold the sp used by the gc and not the sp for popping the arguments. This removes the option of tearing down the frame and returning using one ldm instruction.

The main motivation for this is to avoid pushing an alignment word before generating the entry frame. The GC handling of optimized frames process the registers pushed as part of a safepoint and asumes that these are at the top of the frame, so if an alignment word is pushed this processing will be one off.

The alignment handling in the C entry stub have also been simplified. Now the value of lr is stored to a stack slot already reserved avoiding pushing it and keeping track of "frame skew".

This does result in more instructions in the exit frame on ARM, but we can look into improving this later.

9c2d52eb0e Fix a bug in delete for lookup slots. 
The function Runtime_LookupContext searches the context chain for a
LOOKUP slot and returns the object holding the slot.  It returned the
global context if the slot was not found or if it was found in a
function's context or arguments object.  This is not the correct
object to use for 'delete'.

Since this lookup function is only ever used when deleting LOOKUP
slots (those that have to go through a with or a scope with eval), it
is simply replaced with a Runtime_DeleteContextSlot function that does
the appropriate thing for all kinds of context lookups.

This fixes Chromium bug 70066.

cbc1c0fca6 Truncate rather than round to nearest when performing float-to-integer 
conversions for external array types, which implement the Typed Array
spec. (Revision of http://codereview.chromium.org/6315004 .)

Prefer SSE2 code path on x86 processors. Non-SSE2 processors now make
a slow runtime call for float-to-int conversions. Use SSE3 for 32-bit
signed and unsigned int array types where possible.

The movement of code from ic-arm.cc to stub-cache-arm.cc caused the
VFP3 code path to be tested for the first time. Fixed bugs in the
register usage and in the constant value stored into integer arrays
for NaN and +/-Infinity.

Added new truncation test to test-api.cc. Storage of NaN and +/-Inf
was already covered. Ran unit tests on x86, x64 and ARM simulator.
Tested ia32 and x64 code in Chromium on Mac and Linux respectively
with Typed Array unit tests and WebGL content.

8a9eeaf8da Reapply change to with/arguments interaction. 
This is svn r6415 with a bugfix.

The bug was that we can have scopes with 0 heap slots (functions with
such scopes do not need a local context) and scopes with at least
Context::MIN_CONTEXT_SLOTS.  The code generator only allocated a local
context if there were strictly more than Context::MIN_CONTEXT_SLOTS.
Before the change to with/arguments, it was impossible to actually get
a function scope with exactly Context::MIN_CONTEXT_SLOTS because every
such scope included a heap-allocated arguments (and arguments shadow)
slot.

7f43cf0539 Make 'with' mark only variables occurring in the body as used. 
Before, we conservatively marked every variable in a scope as used if the
scope contained 'with'.  Instead, just mark the variables occurring in the
body of the with.  This avoids marking 'arguments' as used whenever 'with'
occurs, which incurs an extra performance penalty (a use of arguments is
seen as an instruction to redirect all parameter accesses to the arguments
object).

b4ff318e4b Support StringCharCodeAt in hydrogen/lithium. 
This patch adds H- and L-variants of StringCharCodeAt and StringLength.

StringCharCodeAt is used to inline a constant function call of
String.prototype.charCodeAt and to implement the corresponding inline
runtime function. It does not yet use the recently introduced extra IC
state. (We can specialize on string encoding and avoid deopts because
of out of bounds accesses.)

StringLength needs more work because the stub version of it also
supports strings wrappers and it matters in some cases. (We have to
separate the string only case.)

70910af7a0 Fix an assertion failure in the full code generator. 
We hit an assertion failure when we tried to record the AST ID of
the (shared) .arguments variable proxy more than once.  This was hit
when we had multiple calls to the same parameter in a function that
used the arguments object.  The fix is to not visit the subexpressions
of the (shared) property access expression.

27f0ae7aad Truncate rather than round to nearest when performing float-to-integer 
conversions for external array types, which implement the Typed Array
spec. The new code paths are for SSE3 and SSE2 capable processors.
The code for non-SSE2 processors is unchanged for now. The ARM port
appears to already be correct.

Moved the generation of the external array load and store intrinsics
to the stub cache (on all platforms) so that they are generated at run
time and can take advantage of CPU features.

This functionality is covered by the array-unit-tests.html test in the
WebGL conformance test suite:
http://khronos.org/webgl/wiki/Testing/Conformance
https://cvs.khronos.org/svn/repos/registry/trunk/public/webgl/sdk/tests/conformance/array-unit-tests.html

Manually verified all of the SSE3/SSE2/non-SSE2 code paths by enabling
each in turn. Tested in Chromium on 32-bit Mac OS X and 64-bit Linux.

87e82b0452 Remove the remaining LOperand-members from concrete LIR instructions. 
This change introduces the third template parameters for LIR instructions
to specify the number of temp-operands. This is one step towards
removing the instruction-summaries.

I also added hydrogen-accessors in more places and refactored
the LIR-branch instructions to have common super-classes to 
avoid code duplication.

Added MUST_USE_RESULT to the functions that record uses
and definitions so that all LOperands are stored in the
LIR instructions (and not only in the summaries).

437914da90 Change the algorithm and generated code for parallel moves on IA32. 
Instead of spilling and then immediately restoring eax to resolve
memory to memory moves, the gap move resolver now tracks registers
that are known to be free and uses one if available.  If not it spills
but restores lazily when the spilled value is needed or at the end of
the algorithm.

Instead of using esi for resolving cycles and assuming it is free to
overwrite because it can be rematerialized, the gap move resolver now
resolves cycles using swaps, possibly using a free register as above.

The algorithm is also changed to be simpler: a recursive depth-first
traversal of the move dependence graph.  It uses a list of moves to be
performed (because it mutates the moves themselves), but does not use
any auxiliary structure other than the control stack.  It does not
build up a separate list of scheduled moves to be interpreted by the
code generate, but emits code on the fly.

As invocation of a functin may trigger GC and hence clear all the caches,
it's hard to ensure previous invariants.

Finally, this change provides infrastructure to save double registers at safepoints, which is need to call the stub in deferred code.

This change only actually uses the parameter I for input operands. 
Since the parameter T for temps is 0, it incurs no extra cost.

a7c743d3ac Reuse the gap move resolver. 
Rather than allocating a fresh gap move resolver for every parallel
move, use a single one per Lithium code generator.  This avoids always
reallocating the temporary zone-allocated lists used by the gap move
resolver.

Unfortunately, arguments is pretty much the normal JS object.  For now
I am adding more sanity checks (in hope that typically arguments

treatment, for example, we could optimistically copy elements until
we meet first hole and in this case resort to JS builtin.

f89ce8159a Split LInstruction into multiple variant to make our LIR more compact. 
This change introduces LTemplateInstruction which is a specialized version
of LInstruction and takes one template parameter to indicate whether the
instruction produces a result operand.

All instruction that do not have a result inherit from LTemplateInstruction<0>.
Instructions that have a result operand from LTemplateInstruction<1>

All the Define* function only operate on instructions with a result.

For this to work I also refactored the places where we do 

  LInstruction* result = new Lxyy

into

  Lxyz* result = new Lxyz

426f13e084 Fix GC issue in instanceof stub 
The the call of the builtin in InstanceofStub was not correctly protected with an internal frame leading to the return address being handled as a pointer during GC.

Marked the Instanceof stub as allowing stub calls (the RecordWriteStub was removed some days ago).

This issue was not caught by the assertion designed for this when debug mode is run with --debug-code (which out tests always does) as generating code for Abort set the allow stub calls flag to true. This has been fixed by restoring the allow stub calls flag correctly.

2957881a26 Misc debugger enhancements and bug fixes. 
1. Added gdb style debugger commands (and their shortcuts) for d8.
These include:
- s[tep] : step into the current statement.
- s[tep]i[n]: step into the current statement with the minimum step.
- n[ext] : step to the next statement.
- fin[ish] : step out of the current function.
- cond : setting conditions on breakpoints.
- d[elete] : deletes breakpoints.
- en[able]|dis[able]: enables/disables breakpoints including
exception breakpoints.
- ignore : ignores a breakpoint for a specified period.
- inf[o] ar[gs] : info on arguments of the current function.
- inf[o] lo[cals] : info on local vars of the current function.
- inf[o] br[eakpoints] : info on breakpoints.
- l[ist] : similar to source, but allows the user to continually
dump subsequent lines of source code either in the
forward or backward direction.
- quit / exit / disconnect : terminates the remote debugger
session.

NOTE: Active breakpoints will automatically be disabled when
the remote debugger detaches. This allows v8 to continue to
run without worrying about a loss of a debugger session.

2. Added support for breaking the debugger by simply typing ENTER.
The break command is now optional.

3. Once the debugger is broken, the user can now just type ENTER
to repeat the last command. This is useful to functionality that
needs to be invoked repeatedly e.g. step, list.

4. Added more verbose descriptions in d8's help.

5. Fixed a line and column number offset bug in the listing of breakpoint
line and column numbers.

6. Added a gc command to allow GCs to be requested from the debugger
interface. The plumbing for requesting different types of GCs is
there, but the underlying implementation currently only triggers a
full mark-compact GC. The command also returns the before and after
sizes of the heap.

7. Added trace json, and flags commands that are not published in help.
trace json is used for tracing the debugger packets send from and
received by d8. flags is for setting v8 flags. These are useful for
people debugging v8 itself, but not necessarily users of v8.

8. Added the ability to enable and disable break on all / uncaught
exceptions in to d8.

9. Added a fix to prevent the Debugger Agent from being re-instantiated
if one already exists.

10. Added the ability to filter results of the script command by matching
text or numbers on the results.

11. Added v8 flags to enable/disable the sending of debugger BeforeCompile,
AfterCompile, and ScriptCollected events.

12. Fixed some undefined value bugs that resulted in v8 or the debugger
failing.

13. Added a few minor WEBOS__ customizations (analogous to ANDROID
customizations).

2b7596a516 Instanceof slow case bind is incorrect. 
Currently, the bind for the slow label is after the pushing of the
args registers which renders the args pushing dead code because there
is a Ret preceeding it. The comments also imply that the arg pushing
should be part of the InvokeBuiltins tail call.

9a096e643a Fix an bug in deoptimization after polymorphic calls in effect contexts. 
For polymorphic calls (also loads and stores) we construct a type switch
graph that has a basic block merging all the variants.  There is an
environment simulation before the goto at the end of all the predecessor
blocks.  This simulation is used to define the environment on entry to the
successor block, and captures the return value of the call.  In effect
contexts, this value should not be present in the environment.

The fix is to use the AST context to decide whether to have this value in
the join node's environment at all.

7311e10fdb Optimize instanceof further 
If the instance of is performed against what is beliwed to be a constant global function inline the instance of check and have the call to the instanceof stub in deferred code. The inlined check will be patched by the instanceof stub when called from deferred code. This is indicated by the lithium instruction LInstanceOfKnownGlobal.

To help the patching the delta from the return address to the patch site is placed just below the return address in the edi slot of the pushad/popad ares. This is safe because the edi register (which is pushed last) is a temporary for the lithium instruction.

As the instanceof stub can call other JavaScript an additional marking for saving all double registers have been added.

Also tweaked the instanceof stub to produce true/false objects instead of 0/1 for the case with deferred code.

c1fd8bcf60 Fix a bug in deoptimization environments. 
The function HEnvironment::SetExpressionStackAt did not update the
environment's history.  This function is used to patch the bailout
environment for count operations and global function calls.

Reorganize class HEnvironment to make it fit V8's style a bit better
and to try to add some sanity to which C++ functions are intended to
be inlined.

Remove the flag --trace-environment which merely duplicated data in
the hydrogen.cfg file except without enough context to be useful.

1. Separating out the instance-type check from the array-length operation.

2. I also changed the bounds-check on keyed loads to use the length property
for JS arrays (like we do for array stores).

The new pattern should use less registers and allow more checks to be eliminated.

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.

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.
