dd6d2e0737 CallDescriptors::InitializeForIsolate() is no longer needed. 
CallInterfaceDescriptors initialize themselves lazily. Soon we can also tear
down the CodeStubInterfaceDescriptor explicit initialization step.

9514d34e14 Refactoring InterfaceDescriptors away from code-stubs.h 
Clean up and create seperation between the concept of a call descriptor and a
code stub interface descriptor. The former is just concerned with how to call,
but the latter has many extra hints related to code generation and
deoptimization for the implementation of a particular code stub.

90c8932596 Replace our homegrown ARRAY_SIZE() with Chrome's arraysize(). 
Our own ARRAY_SIZE() was pretty bad at error checking. If you use
arrasize() in a wrong way, the compiler will issue an error instead of
silently doing the wrong thing. The previous ARRAY_SIZE() macro is still
available as ARRAYSIZE_UNSAFE() similar to Chrome.

gyp and test status files updates.

- On mips64 simulator all tests pass from all test units.

- Current issues: mjsunit JS debugger tests fail randomly on HW in release mode.
Corresponding tests are skipped on HW.

- Skipped tests on mips64: test-heap/ReleaseOverReservedPages, mjsunit/debug-*

The callbacks are per isolate, so we shouldn't get the isolate implicitly
from TLS. Also, we shouldn't allow calls to these methods prior to
initializing the respective isolate (and silently ignore them).

Esp. add a per-isolate API to set the stats counter callbacks and
make it possible to set the stats counter callback after the isolate
was touched.

Embedders should use e.g. isolate->SetCounterFunction(callback) instead
of v8::V8::SetCounterFunction(callback).

This adds timestamps to allow profiling with code space reuse. Also a couple of updates to reflect the changes in the JIT perf interface + a move of the perf-related stuff into separate files.

Unfortunately, the change only works with the latest patch  to the perf tool from a Linux perf tool contributor (Stephane Eranian).

6ff2a77364 Wrap InitializeProperty around SetOwnPropertyIgnoreAttributes and switch over uses 
This is a step in the direction of disentangling all uses of SetOwnPropertyIgnoreAttributes so we can provide a more specific implementation for those usecases, and reduce the capabilities of those clients, avoiding subtle bugs.

InitializeProperty only supports adding properties to extensible objects that do not contain the property yet. JSGlobalProxies cannot have properties themselves, so are not supported either.

20eeff9ae4 Allow microtasks to throw exceptions and handle them gracefully 
If the embedder calls V8::TerminateExecution while we're running microtasks, bail out
and clear any pending microtasks.

All other exceptions are simply swallowed. No current Blink or V8 microtasks throw, this
just ensures something sane happens if another embedder decides to pass a throwing
microtask (or if ours unexpectedly throw due to, e.g., stack exhaustion).

35b8b0b27a Move microtask queueing logic from JavaScript to C++ 
This avoids the appearence of a leak due to storing a JSObject
as the microtask_state in the strong root list, and allows callers
to call Isolate::RunMicrotasks() without having any v8::Context
available (as at least Blink has interest in doing).

The queue is now a strong root, represented as a FixedArray of JSFunctions
(or empty_fixed_array, if it's empty); it doubles in size when it needs to grow.
The number of elements in the queue is stored in Isolate::pending_microtask_count().

8f170a66e7 Improve positions tracking inside the HGraphBuilder. 
Instead of tracking simple absolute offset from the start of the script like other places do, track a pair of (inlining id, offset from the start of inlined function).

This enables us to pinpoint with inlining path an instruction came from. Previously in multi-script environments we emitted positions that made very little sense because inside a single optimized function they would point to different scripts without a way to distinguish them.

Start dumping the source of every inlined function to make possible IR viewing tools with integrated source views as there was previously no way to acquire this information from IR dumps. We also dump source position at which each inlining occured.

Tracked positions are written into hydrogen.cfg as pos:<inlining-id>_<offset>.

Flag --emit-opt-code-positions is renamed by this change into --hydrogen-track-positions to better convey it's meaning.

In addition this change assigned global unique identifier to each optimization performed inside isolate. This allows to precisely match compilation artifacts (e.g. IR and disassembly) and deoptimizations.

99ce5a2484 The current 
version is passing all the existing test + a bunch of new tests
(packaged in the change list, too).

The patch extends the SlotRef object to describe captured and duplicated
objects. Since the SlotRefs are not independent of each other anymore,
there is a new SlotRefValueBuilder class that stores the SlotRefs and
later materializes the objects from the SlotRefs.

Note that unlike the previous implementation of SlotRefs, we now build
the SlotRef entries for the entire frame, not just the particular
function.  This is because duplicate objects might refer to previous
captured objects (that might live inside other inlined function's part
of the frame).

We also need to store the materialized objects between other potential
invocations of the same arguments object so that we materialize each
captured object at most once.  The materialized objects of frames live
in the new MaterielizedObjectStore object (contained in Isolate),
indexed by the frame's FP address.  Each argument materialization (and
deoptimization) tries to lookup its captured objects in the store before
building new ones.  Deoptimization also removes the materialized objects
from the store. We also schedule a lazy deopt to be sure that we always
get rid of the materialized objects and that the optmized function
adopts the materialized objects (instead of happily computing with its
captured representations).

Concerns:

- Is the FP address the right key for a frame? (Note that deoptimizer's
representation of frame is different from the argument object
materializer's one - it is not easy to find common ground.)

- Performance is suboptimal in several places, but a quick local run of
benchmarks does not seem to show a perf hit. Examples of possible
improvements: smarter generation of SlotRefs (build other functions'
SlotRefs only for captured objects and only if necessary), smarter
lookup of stored materialized objects.

- Ideally, we would like to share the code for argument materialization
with deoptimizer's materializer.  However, the supporting data structures
(mainly the frame descriptor) are quite different in each case, so it
looks more like a separate project.

Thanks for any feedback.

868ad01ecb This is a preview of the captured arguments object materialization, 
mostly to make sure that it is going in the right direction. The current

The patch extends the SlotRef object to describe captured and duplicated
objects. Since the SlotRefs are not independent of each other anymore,

get rid of the materialized objects and that the optmized function
adopts the materialized objects (instead of happily computing with its

Concerns:

- Is there a simpler/more correct way to store the already-materialized
objects? (At the moment there is a custom root reference to JSArray
containing frames' FixedArrays with their captured objects.)

- Is the FP address the right key for a frame? (Note that deoptimizer's
representation of frame is different from the argument object
materializer's one - it is not easy to find common ground.)

19d832719e This is a preview of a first step towards unification of the hydrogen 
call machinery.  The change replaces CallNamed, CallKeyed,
CallConstantFunction and CallKnownGlobal hydrogen instructions with two
new instructions with a more lower level semantics:

1. CallJSFunction for direct calls of JSFunction objects (no
   argument adaptation)

2. CallWithDescriptor for calls of a given Code object according to
   the supplied calling convention.

Details:

CallJSFunction should be straightforward, the main difference from the
existing InvokeFunction instruction is the absence of argument adaptor
handling. (As a next step, we will replace InvokeFunction with an
equivalent hydrogen code.)

For CallWithDescriptor, the calling conventions are represented by a
tweaked version of CallStubInterfaceDescriptor. In addition to the
parameter-register mapping, we also define parameter-representation
mapping there. The CallWithDescriptor instruction has variable number of
parameters now - this required some simple tweaks in Lithium, which
assumed fixed number of arguments in some places.

The calling conventions used in the calls are initialized in the
CallDescriptors class (code-stubs.h, <arch>/code-stubs-<arch>.cc), and
they live in a new table in the Isolate class. I should say I am not
quite sure about Representation::Integer32() representation for some of
the params of ArgumentAdaptorCall - it is not clear to me wether the
params could not end up on the stack and thus confuse the GC.

The change also includes an earlier small change to argument adaptor
(https://codereview.chromium.org/98463007) that avoids passing a naked
pointer to the code entry as a parameter. I am sorry for packaging that
with an already biggish change.

Performance implications:

Locally, I see a small regression (.2% or so). It is hard to say where
exactly it comes from, but I do see inefficient call sequences to the
adaptor trampoline. For example:

;;; <@78,#24> constant-t
bf85aa515a     mov edi,0x5a51aa85          ;; debug: position 29
;;; <@72,#53> load-named-field

b902000000     mov ecx,0x2                 ;; debug: position 195
;;; <@81,#51> gap
894df0         mov [ebp+0xf0],ecx
;;; <@82,#103> constant-i
bb01000000     mov ebx,0x1
;;; <@84,#102> constant-i
b902000000     mov ecx,0x2
;;; <@85,#102> gap
89d8           mov eax,ebx
89cb           mov ebx,ecx
8b4df0         mov ecx,[ebp+0xf0]
;;; <@86,#58> call-with-descriptor
e8ef57fcff     call ArgumentsAdaptorTrampoline  (0x2d80e6e0)    ;; code: BUILTIN

Note the silly handling of ecx; the hydrogen for this code is:

84aa5263f3 Remove the last remnants of the TranscendentalCache. 
It was only used for Math.log, and even then only in full code and in %_MathLog. For crankshafted code, Intel already used the FP operations directly, while the ARM/MIPS ports were a bit lazy and simply called the stub. The latter directly call the C library now without any cache. It would be possible to directly generate machine code if somebody has the time, from what I've seen out in the wild it should be only about a dozen instructions.

Previously BinaryOpIC and BinaryOpStub were pretty much interdependent.
However, in order to use allocation sites for string adds on-demand,
we need to be able to use different stubs (with a different number of
register parameters, via trampolines) depending on the BinaryOpIC state.

4e439deb0b Support for the Linux 'perf report' and 'perf annotate' tools. 
In this change, the support comes in two flavours:

--perf_jit_prof - outputs the files in a new perf format that only works with a
patched perf tool (patch obtained from Stephane Eranian). Both 'perf report' and
'perf annotate' are supported (the file format also contains the machine code).

--perf_basic_prof - outputs the files in a format that the existing perf tool
can consume. Only 'perf report' is supported.

In both cases, we have to disable code compaction because the perf tool does not
understand code relocation. (We are told that code relocation should be
supported soon.)

Usage:

perf record -g d8 --perf_jit_prof --no_compact_code_space my.js
perf report

The change itself is straightforward - we simply listen to code events and
write an entry to a log file for every new piece of code.

I am not yet sure whether we should keep both versions or just one (and which
one). My hope is the reviewers can help here.

When redirection is enabled but --redirect_code_traces_to is not specified traces are written to a file code-<pid>-<isolate>.asm. This mangling scheme matches hydrogen.cfg and allows easy discovery of compilation artifacts in a multi-V8 environment (e.g. when compilation is traced from inside Chromium).

D8 defines --redirect_code_traces_to=code.asm similar to hydrogen.cfg redirection.

It introduces static initializers for the new "MAYBE_BOOL" kind of

eb381b9444 Introduce a RandonNumberGenerator class. Refactor the random/private_random uses in Isolate/Context. 
The RandomNumberGenerator is a pseudorandom number generator
with 48-bit state. It is properly seeded using either

(1) the --random-seed if specified, or
(2) the entropy_source function if configured, or
(3) /dev/urandom if available, or
(4) falls back to Time and TimeTicks based seeding.

Each Isolate now contains a RandomNumberGenerator, which replaces
the previous private_random_seed.

Every native context still has its own random_seed. But this random
seed is now properly initialized during bootstrapping,
instead of on-demand initialization. This will allow us to cleanup
and speedup the HRandom implementation quite a lot (this is delayed
for a followup CL)!

Also stop messing with the system rand()/random(), which should
not be done from a library anyway! We probably re-seeded the
libc rand()/random() after the application (i.e. Chrome) already
seeded it (with better entropy than what we used).

Another followup CL will replace the use of the per-isolate
random number generator for the address randomization and
thereby get rid of the Isolate::UncheckedCurrent() usage in
the platform code.

97f8f91bb5 Fix call stack sampling for the case when native callback invokes JS function 
The SafeStackFrameIterator used by CPU profiler checked if Isolate::c_entry_fp is null and if it is not it would think that the control flow currently is in some native code. This assumption is wrong because the native code could have called a JS function but JSEntryStub would not reset c_entry_fp to NULL in that case. This CL adds a check in SafeStackFrameIterator::IsValidTop for the case when there is a JAVA_SCRIPT frame on top of EXIT frame.

Also this CL changes ExternalCallbackScope behavior to provide access to the whole stack of the scope objects instead of only top one. This allowed to provide exact callback names for those EXIT frames where external callbacks are called. Without this change it was possible only for the top most native call.

that it re-enables printing of code objects in GDB. NOT: To make the latter
