77fffe2207 X64: Implement DoComputeOsrOutputFrame and fix Generate_OnStackReplacement. 
The existing version does not have a correct implementation of
Generate_OnStackReplacement since we do not correctly find the loop
depth. This is mainly because EmitStackCheck in full-codegen-x64.cc
did not write it and partly due to us reading at the wrong offset
(which had no effect when it was not written in the first place, we
simply got a random number from the next instruction).

The DoComputeOsrOoutputFrame is very similar to the ia32 version.

Since writting a code comment can include a pc-jump the assertion
should just check that we are greater than or equal to
kMinRelocCommentSize (renamed from kRelocCommentSize), not that we are
actually equal to.

We can wrongly assume that exception which is not intended to be caught
by external try/catch should be caught if this exception inherits
external catcher from some previous exception.  To prevent that,
clear external catcher when processing exceptions which cannot be
externally caught.

56788625b6 Fix CPU profiling for Crankshaft. 
The main issue was due to multiple recompilations of functions.  Now
code objects are grouped by function using SFI object address.
JSFunction objects are no longer tracked, instead we track SFI object
moves. To pick a correct code version, we now sample return addresses
instead of JSFunction addresses.

tools/{linux|mac|windows}-tickprocessor scripts differentiate
between code optimization states for the same function
(using * and ~ prefixes introduced earlier).

DevTools CPU profiler treats all variants of function code as
a single function.

ll_prof treats each optimized variant as a separate entry, because
it can disassemble each one of them.

tickprocessor.py not updated -- it is deprecated and will be removed.

45c63ffa6a Add more generic version of reloc info padding to ensure enough space for reloc patching during deoptimization (fixes issue 1174). 
The old version only added extra space when we did indirect calls, but
the problem remains the same with normal calls that can be represented
as a single byte. When doing patching each call will always be at
least 2 bytes long because we use RUNTIME_ENTY as the reloc mode.

031062d246 Fix bug with input representation of HValueOf. 
The class did not correctly implement the RequiredInputRepresentation.
I changed this functions to be abstract so that all hydrogen classes
must implement it.

As a convention instructions with zero input operands return None as input
representation.

Instructions that can handle all input representations without converting before
also have None as required input representation (e.g. HTest)

All other instructions need a proper required input representation.

2ab5691ac1 ARM: Add support for just one string argument in the string add stub 
Having a string add stub which can handle a string in just one of the arguments is essencial for the type recording binary operation stub when expecting strings. Otherwise string added with e.g. smi will always call the runtime for a type transition which will be back to the same types as the transition code keeps it in string arguments when one argument is a string.

This fixes the regression (especially Delta Blue) caused by replacing the generic binary operation stub with the type recording binary operation stub in the ARM lithium code generator.

c1386c3381 Shorten live ranges for arguments to runtime calls. 
Before, the live ranges of the arguments extended to the call itself, and
they were pushed immediately before the call.  Now, they are spilled eagerly
as soon as their value is available and they are spilled to the right place.

The inlined runtime calls in the optimized backend are changed to work as in
all the other backends: they get their arguments untranslated and can choose
their own custom evaluation order.

Call accessors in the global object prototype when initializing global
variables. Function declarations are special cased for compatibility
with Safari and setters are not called for them. If this special
casing was not done webkit layout tests would fail.

callbacks a redeclaration error.

a redeclaration error. That is, unless it is on a context extension
object which is not a real object and therefore conceptually have no
accessors in prototype chains. Accessors in prototype chains of
context extension objects are explicitly ignored in SetProperty.

When deoptimizing to after an expression of the form (expr0 || expr1)

incorrectly see the value of the expression.

6b4ff18b5b Properly process try/finally blocks. 
In some circumstances, try/finally block can actually catch the exception:

function f() {
  try {
    throw 42;
  } finally {
    return 0;
  }
}

Therefore when propagating exception to v8::TryCatch, we must be sure
there is no try/finally blocks as well.

When bulding the messages we should be more conservative and expect that
any v8::TryCatch with no JS try/catch in between can potentionally
be the right exception handler.

Plus various minor refactorings.

316a12dea9 Added gdb-jit interface support for ARM. Compressed .debug_line table by 1) 
removing duplicate adjacent entries having the same line number, and 2) using
special opcodes to encode multiple machine register state changes in one byte.
Also made a fix involving the order in which static initializers are performed.

0976d48ba6 Fix wrong assert in ia32 deoptimizer. 
In revision 6795 I introduced an assertion in the deoptimizer that was
wrong. We check that curr_address - prev_address > patch_size(), but
prev_address is actually the address right after the last patched
call, so we just need to be larger than or equal to prev_address.

this case (from lithium codegen) we now emit a comment in the reloc

Rather than passing in a pair of unequal-length lists, pass the default
subgraph separately.  Construct the typecase from the top down rather than
the bottom up, so it doesn't need an intermediate zone list.

Also, change a basic block's 'last' instruction field to really be its last
instruction by correctly updating it when inserting and removing
instructions.

The current version uses SetObjectProperty which will not set the
value in case this is a readonly property. The spec explictly says
that a configurable but non writable property can have its value
changed with Object.defineProperty (because the same thing can be
accomplished by doing 3 calls (set writable to true, update the value,
set writable to false).

3ef7ca6c28 Remove the uses of the arguments from all calls. 
Before, Hydrogen call instructions had uses of the PushArgument instructions
for their arguments.  These operands were unneeded, bloated the IR, and
caused calls to be the only Hydrogen instructions with an unpredictable
number of operands.

Now, PushArgument is a pure side-effecting instruction that has no uses.

2e08148b06 Fix the semantics of delete on parameters. 
Before, an attempt to delete a parameter in a function that used the
arguments object in any way would succeed with true and delete both
the parameter and the corresponding arguments object property.

Now, an attempt to delete such a parameter does not delete and
evaluates to false.

Parameters can be deleted, as before, from functions that use the
arguments object, by deleting the corresponding arguments object
property (this is a spec violation).

ebebcae4c2 Allow esi to be an allocatable register on IA32. 
Make esi available to the register allocator rather than dedicating it
permanently to the context.

The context is still passed in register esi to JavaScript and to the runtime
as part of the calling convention.  Because some stubs might end up calling
JS or the runtime, it is also conservatively passed to stubs.

Roughly half the calls have been modified to use the context as an input
value in fixed register esi.  The other half are marked as calls or deferred
code so esi is spilled and can be explicitly set.

It is no longer necessary to restore the context to esi after a call that
might change it.

dabc590527 ARM: Add type-feedback recording for compare 
Change the comparison in the full code generator to use CompareIC instead of the CompareStub to record the types. This also implements the patching in the full code generator where the inlined smi code is de-activated by default to call the CompareIC once and then activating the inlined smi code by patching the code.

Fixed the smi comparison in the ICCompareStub.

Fixed ToBooleanStub to ensure that the scratch register used is not the input. Use r9 as default as that will never be input with Crankshaft.

Implemented lithium instruction CmpTAndBranch.

Make sure that the lithium instruction CmpID have operands in registrers as the current optimized code expects that.

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.

In addition to the regression test I changed the gc-extension to take
a boolean flag specifying if compaction should be used (default is
false, existing tests will not change behaviour)

The regression test is disabled on arm and x64 with crankshaft

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.

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.

24843d6310 Introduce ToNumber stub and use it in non-optimized code for to-number conversion. 
This stub is used for increment/decrement operations and unary plus.
The resulting code is more compact and faster than calling a JS builtin.

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'.

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.

ReferenceError.prototype.__proto__ which will make "error instanceof

cannot be modified. Therefore, the error checks must check for

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).

1c2fddb4c8 ARM: Implement Math.abs in lithium code generator for the integer and

leaving that unimplemented for now.

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.

11a4cb5718 Introduce extra IC state to record additional feedback from IC-s. 
Extra IC state is only two bits and only supported for call IC-s for
now. To change its extra state an IC stub jumps to a new miss stub
that goes to runtime as usual but then instead of going megamorphic
generates a monomorphic stub with the updated state.
