cb29f9cdbc [Interpreter] Add support for cpu profiler logging.
Adds support for cpu profiler logging to the interpreter. Modifies the
the API to be passed AbstractCode objects instead of Code objects, and
adds extra functions to AbstractCode which is required by log.cc and
cpu-profiler.cc.

The main change in sampler.cc is to determine if a stack frame is an
interpreter stack frame, and if so, use the bytecode address as the pc
for that frame. This allows sampling of bytecode functions. This
requires adding support to SafeStackIterator to determine if a frame is
interpreted, which we do by checking the PC against pre-stored addresses
for the start and end of interpreter entry builtins.

Also removes CodeDeleteEvents which are dead code and haven't
been reported for some time.

Still to do is tracking source positions which will be done in a
followup CL.

01b8fc894b Reland "Replace slots buffer with remembered set. (patchset #14 id:250001 of https://codereview.chromium.org/1703823002/ )"
This reverts commit 9146bc5e20.

This contains a fix for the following crash:
1. We record slots for a fixed array.
2. We trim the fixed array, so that some recorded slots are now in free space.
3. During mark-compact we sweep the page with the fixed array. Now free list items contain memory with recorded slots.
4. We evacuate a byte array using the new free list items.
5. We iterate slots that are now inside the byte array and crash.

8a7186b87a [turbofan] Remove the JSContextRelaxation reducer.
This reducer doesn't really add value, because:

 (a) it is only concerned with JSCallFunction and JSToNumber, but when
     we get to it, all JSCallFunction nodes will have been replaced by
     Call nodes, and in the not so far future, we will also have
     replaced almost all JSToNumber nodes with better code,
 (b) and the reducer tries to be smart and use one of the outermost
     contexts, but that might not be beneficial always; actually it
     might even create longer live ranges and lead to more spilling
     in some cases.

But most importantly, the JSContextRelaxation currently blocks inlining
based on SharedFunctionInfo, because it requires the inliner to check
the native context, which in turn requires JSFunction knowledge. So I'm
removing this reducer for now to unblock the more important inliner
changes.

4fdc19ae33 Add a generic remembered set class.
This new class provides a unified interface for recording and iterating slots in store and slots buffers:

RememberedSet<OLD_TO_NEW>::Insert(page, slot);
RememberedSet<OLD_TO_OLD>::Insert(page, slot);

RememberedSet<OLD_TO_NEW>::Iterate(heap, callback);
RememberedSet<OLD_TO_OLD>::Iterate(heap, callback);

After this change the store buffer is responsible only for collecting slots from the generated code.

Subsequent CLs will remove the slots buffer.

d1c28849c7 [Interpreter] Make InterpreterAssembler a subclass of CodeStubAssembler.
Moves InterpreterAssembler out of the compiler directory and into the
interpreter directory. Makes InterpreterAssembler as subclass of
CodeStubAssembler.

As part of this change, the special bytecode dispatch linkage type
is removed and instead we use a InterfaceDispatchDescriptor and
a normal CodeStub linkage type.

Removes a bunch of duplicated logic in InterpreterAssembler and
instead uses the CodeStubAssembler logic. Refactors Interpreter
with these changes.

Modifies CodeStubAssembler to add the extra operations required
by the Interpreter (extra call types, raw memory access and some extra
binary ops). Also adds the ability for subclasses to add extra
prologue and epilogue operations around calls, which is required
for the Interpreter.

bb883395a8 New page local store buffer.
This replaces the global remembered set with per-page remembered sets.

Each page in the old space, map space, and large object space keeps track of
the set of slots in the page pointing to the new space.

The data structure for storing slot sets is a two-level bitmap, which allows
us to remove the store buffer overflow and SCAN_ON_SCAVENGE logic.

ef35f11c43 Remove the template magic from types.(h|cc), remove types-inl.h.
This CL removes the Config templatization from the types. It is not
necessary anymore, after the HeapTypes have been removed.

The CL also changes the type hierarchy - the specific type kinds are
not inner classes of the Type class and they do not inherit from Type.
This is partly because it seems impossible to make this work without
templates. Instead, a new TypeBase class is introduced and all the
structural (i.e., non-bitset) types inherit from it.

The bitset type still requires the bit-munging hack and some nasty
reinterpret-casts to pretend bitsets are of type Type*. Additionally,
there is now the same hack for TypeBase - all pointers to the sub-types
of TypeBase are reinterpret-casted to Type*. This is to keep the type
constructors in inline method definitions (although it is unclear how
much that actually buys us).

In future, we would like to move to a model where we encapsulate Type*
into a class (or possibly use Type where we used to use Type*). This
would loosen the coupling between bitset size and pointer size, and
eventually we would be able to have more bits.

004ce08da6 Reland of "[heap] Parallel newspace evacuation, semispace copy, and compaction \o/"
This reverts commit 85ba94f28c.

All parallelism can be turned off using --predictable, or --noparallel-compaction.

This patch completely parallelizes
 - semispace copy: from space -> to space (within newspace)
 - newspace evacuation: newspace -> oldspace
 - oldspace compaction: oldspace -> oldspace

Previously newspace has been handled sequentially (semispace copy, newspace
evacuation) before compacting oldspace in parallel. However, on a high level
there are no dependencies between those two actions, hence we parallelize them
altogether. We base the number of evacuation tasks on the overall set of
to-be-processed pages (newspace + oldspace compaction pages).

Some low-level details:
 - The hard cap on number of tasks has been lifted
 - We cache store buffer entries locally before merging them back into the global
   StoreBuffer in a finalization phase.
 - We cache AllocationSite operations locally before merging them back into the
   global pretenuring storage in a finalization phase.
 - AllocationSite might be compacted while they would be needed for newspace
   evacuation. To mitigate any problems we defer checking allocation sites for
   newspace till merging locally buffered data.

19df7a20f0 [interpreter] Wide register support.
This increases the size of register operands to be 16-bit.

Not all bytecodes have wide register variants, so when they are
needed a register translator will copy them into a small area
reserved at the top of the 8-bit register range and these registers
are supplied as arguments to the bytecode with 8-bit operands.

This is non-intrusive for typical bytecode where the number of
registers is less than 120. For bytecodes with wide register
operands (above the window) their index needs to be translated
to avoid the reserved translation window.

Enables splay.js to run in Octane and a handful of mjsunit tests.

Unlike AllocationTracking, this is intended to be cheap and usable online in

The proof-of-concept is only sampling new-space allocations at this point.
Support for sampling paged space and native allocations is anticipated in the
future.

This removes the above flag definition. The flag is no longer needed as
the default implementation is more than capable of faking presence of

This implements a first version of exception handler table construction
within the interpreter. Note that the local control flow for try-catch
and try-finally statements is still off, and also stack unwinding does
not yet respect interpreter frames. But generated handler tables should
be populated correctly already.

0aeaf0cbd1 Move SourcePosition into separate header file.
This splits out the SourcePosition class into a separate header file.
Reason for this refactoring is that said class is mostly used by the
Crankshaft compiler and not needed for all compilers. Also having the

55422bdd50 [heap] Use HashMap as scratchpad backing store
We use a scratchpad to remember visited allocation sites for post processing
(making tenure decisions). The previous implementation used a rooted FixedArray
with constant length (256) to remember all sites. Updating the scratchpad is a
bottleneck in any parallel/concurrent implementation of newspace evacuation.

The new implementation uses a HashMap with allocation sites as keys and
temporary counts as values. During evacuation we collect a local hashmap of
visited allocation sites. Upon merging the local hashmap back into a global one
we update potential forward pointers of compacted allocation sites.  The
scavenger can directly enter its entries into the global hashmap. Note that the
actual memento found count is still kept on the AllocationSite as it needs to
survive scavenges and full GCs.

70a7c754bf Implement tracing interface for v8
This is based on the Skia Implementation.

More on the project can be found here:
https://docs.google.com/a/chromium.org/document/d/1_4LAnInOB8tM_DLjptWiszRwa4qwiSsDzMkO4tU-Qes/edit#heading=h.p97rw6yt8o2j

The V8 Tracing platform will replace the isolate->event_logger().
But since the current embedders (namely chromium) currently use the isolate->event_logger, I made the default implementation (event-tracer) call into isolate->event_logger if an event_logger was set.
Once the embedders properly implement the interface (for example in chromium it would look like this: https://codereview.chromium.org/707273005/), the default implementation will be doing nothing.

Once the embedders side is fixed, we will change how V8 uses the tracing framework beyond the call from Logger:CallEventLogger. (which would also include a d8 implementation)

4c5b3609fd Initial import of v8-native WASM.
As discussed in person, this adds the code from v8-native-prototype into
V8 proper, guarded by GYP flags that do not build the code by default.
Passing wasm=on to 'make' or setting v8_wasm as a GYP flag activates
building of this code.

An additional header file is added to and exported from the compiler
directory, src/compiler/wasm-compiler.h. This exposes a limited interface
with opaque Node and Graph types to the decoder to build TF graphs, as
well as functions to compile WASM graphs.

The mjsunit tests added are blacklisted because they fail without the
WASM object exposed to JS, which is also disabled by the build config
option.

This corresponds closely to 5981e06ebc, with some formatting fixes and moving some files into src/compiler.

f564231a6b Revert of Re-land FastAccessorBuilder. (patchset #2 id:20001 of https://codereview.chromium.org/1504713012/ )
Reason for revert:
Meeh. Now "V8 Linux - gcmole" bot has issues; apparently due to a somewhat exotic builder configuration.

3e7e3ed726 [stubs] A new approach to TF stubs
* Add a sibling interface to InterpreterAssembler called
  CodeStubAssembler which provides a wrapper around the
  RawMachineAssembler and is intented to make it easy to build
  efficient cross-platform code stubs. Much of the implementation
  of CodeStubAssembler is shamelessly stolen from the
  InterpreterAssembler, and the idea is to eventually merge the
  two interfaces somehow, probably moving the
  InterpreterAssembler interface over to use the
  CodeStubAssembler. Short-term, however, the two interfaces
  shall remain decoupled to increase our velocity developing the
  two systems in parallel.
* Implement the StringLength stub in TurboFan with the new
  CodeStubAssembler. Replace and remove the old Hydrogen-stub
  version.
* Remove a whole slew of machinery to support JavaScript-style
  code stub generation, since it ultimately proved unwieldy,
  brittle and baroque. This cleanup includes removing the shared
  code stub context, several example stubs and a tangle of build
  file changes.

This is the first part of escape analysis for turbofan.
At the moment, there is no deopt support, and support
for loops is partial (only binary Phis are handled).

The CL includes 4 unittests.

There are also 8 new mjsunit tests, some of which are
skiped as they require features not yet implemented.

f39d1cd4aa [test] Switch off perf data feature on swarming.
The feature sometimes prevents subsequent swarming bots to
delete the work directory on windows.

The data file is not kept on swarming bots anyways, therefore
this switches off the feature completely.

138eb324ea Object's body descriptors refactoring.
1) Body descriptors moved to their own header files.
2) Missing body descriptors added.
3) Template versions of HeapObject::Iterate*() methods added.
4) Body descriptors support new kind of queries: IsValidSlot(offset) which can be used for invalid slots filtering.

This is a first step towards virtual and static visitors unification and support in-object properties in built-in (sub-)classes.

55c07a8b2f [turbofan] Introduce JSCallReducer to strength reduce JSCallFunction nodes.
The JSCallReducer runs together with inlining and tries to strength
reduce JSCallFunction nodes; currently it can fold
Function.prototype.call and Function.prototype.apply (with arguments),
and make it possible to inline across them.

In the case of Function.prototype.apply with arguments we still have to
leave the JSCreateArguments node in the graph because there might be
other (frame state) uses. Once escape analysis is ready, it will take
care of removing these nodes and adding appropriate transitions for the
deoptimizer.

4eb41ba738 [turbofan] Split JSGlobalObjectSpecialization into separate class.
The JSNativeContextSpecialization class is getting rather huge with all
the stuff related to property and element access going in. Splitting off
the global object related stuff into JSGlobalObjectSpecialization seems
like a natural separation, especially since the global object
specialization is sort of separate issue anyway.  This is neutral
functionality- and performance-wise.

efcc7fb2bd [Swarming] Let test runner exit gracefully after test failures.
The flake detection is done on the infra-side according to
the contents of the json test results. We don't want the
runner to fail after flakes.

This was controlled on the infra side by accepting any exit
codes so far. After the swarming switch, this is more
difficult, because the runner is wrapped by the swarming
collect script. There, failing exit codes can mean many
things, including network failures. Therefore, we now
force exit code 0 with test failures if those failures
are reported in the formal test results json.

The infrastructure will take care of reporting the flakes
and failures accordingly.

23ac686ff8 [types] Use the TypeCache consistently for common types.
Rename ZoneTypeCache to TypeCache and use a single shared (immutable)
instance consistently to cache the most commonly used types. Also serves
as a chokepoint for defining those types, so we don't repeat the
definition (and possible bugs) in various places.

71bde166b1 [turbofan] Remove obsolete JSTypeFeedbackSpecializer and JSTypeFeedbackLowering.
Both the JSTypeFeedbackSpecializer and the JSTypeFeedbackLowering is
dead code by now, since the more general JSNativeContextSpecialization
deals with the property/global load/store type feedback in a way that
also interacts properly with inlining.

02e4d21f4c [es6] Fix scoping for default parameters in arrow functions
When eagerly parsing arrow functions, expressions in default
parameter initializers are parsed in the enclosing scope,
rather than in the function's scope (since that scope does not
yet exist). This leads to VariableProxies being added to the
wrong scope, and scope chains for FunctionLiterals being incorrect.

This patch addresses these problems by adding a subclass of
AstExpressionVisitor that moves VariableProxies to the proper
scope and fixes up scope chains of FunctionLiterals.

This is a revert of the revert https://crrev.com/e41614a058426fb6102e4ab2dd4f98997f00c0fc
with a much-improved (though not yet perfect) Scope::ResetOuterScope
method which properly fixes not only the outer_scope_ pointer but also
fixes the inner_scope_ list in the relevant outer_scopes.

More work likely still needs to be done to make this work completely,
but it's very close to correct.

106aecf262 [turbofan] Redundant branch elimination.
Removes a branch that checks for a condition that has been checked on dominators of the branch.

This introduces a new reducer that propagates the list of checked conditions (and their boolean values) through the control flow graph. If it encounters a branch checking a condition with a known value, the branch is eliminated.

The analysis relies on loops being reducible: if a condition has been checked on all paths to loop entry, then it is checked in the loop (regardless what of the conditions checked inside the loop).

The implementation is fairly naive and could be improved:

- all the operation on the condition lists could be made allocation-free when revisited.

- we could try to use a map structure rather than a linked list (to make
lookups faster).

- the merging of control flow could be changed to take into account
  conditions from non-dominating paths (as long as all paths check
  the condition).

Note that files in the "debug" directory as well as the "d8.js" file

e16dd13d6d [turbofan] Add initial support for global specialization.
Introduce a new JSGlobalSpecialization advanced reducer that runs
during the initial inlining and context specialization, and specializes
the graph to the globals of the native context.  Currently we assume
that we do not inline cross native context, but long-term we will grab
the global object from the JSLoadGlobal/JSStoreGlobal feedback (with the
new global load/store ICs that are currently in the workings), and then
this whole specialization will be fully compositional even across
cross-context inlining.

Note that we cannot really handle most of the stores to global object
property cells because TurboFan doesn't have a mechanism to enforce
certain representations.  Also note that we cannot yet fully benefit
from the type feedback collected on the global object property cells,
because the type system cannot deal with maps in a reasonable way.

This adds the unittests to the "default" test set. Now that
the "default" and the DEFAULT_TESTS (i.e. runner with

TEST_MAP["default"] instead.

On the bots, where unittests and default were run in
separation before, the explicit unittests step should now
be skipped.

This is necessary for swarming, as the unittests step is
too small to justify its own swarming job.

5cf1c0bcf6 Re-reland: Remove register index/code indirection
Previous to this patch, both the lithium and TurboFan register
allocators tracked allocated registers by "indices", rather than
the register codes used elsewhere in the runtime. This patch
ensures that codes are used everywhere, and in the process cleans
up a bunch of redundant code and adds more structure to how the
set of allocatable registers is defined.

Some highlights of changes:

* TurboFan's RegisterConfiguration class moved to V8's top level
  so that it can be shared with Crankshaft.
* Various "ToAllocationIndex" and related methods removed.
* Code that can be easily shared between Register classes on
  different platforms is now shared.
* The list of allocatable registers on each platform is declared
  as a list rather than implicitly via the register index <->
  code mapping.

9bd83f58f2 [swarming] Isolate v8 testing.
Add gyp support and isolates for default test suites.
Add two default isolates, one (default) for using the
test suite collection we call "default" on the bots. One
(developer_default) for also supporting the way developers
call the driver (i.e. without argument, which includes
the unittests).

7b7a8205d9 Remove register index/code indirection
Previous to this patch, both the lithium and TurboFan register
allocators tracked allocated registers by "indices", rather than
the register codes used elsewhere in the runtime. This patch
ensures that codes are used everywhere, and in the process cleans
up a bunch of redundant code and adds more structure to how the
set of allocatable registers is defined.

Some highlights of changes:

* TurboFan's RegisterConfiguration class moved to V8's top level
  so that it can be shared with Crankshaft.
* Various "ToAllocationIndex" and related methods removed.
* Code that can be easily shared between Register classes on
  different platforms is now shared.
* The list of allocatable registers on each platform is declared
  as a list rather than implicitly via the register index <->
  code mapping.

366dc81143 [Swarming] Presort tests - slowest first.
Swarming won't support an incremental data file. By just
sorting the lowest hanging fruits to the beginning we
already get a big bang for the buck (>80% of the improvement
we get otherwise).

This will require semi-regular manual updates of the
slowest tests.

Adds support for short operands, starting with kIdx16. Introduces
BytecodeTraits to enable compile time determination of various traits for a
bytecode, such as size, operands, etc. Reworks BytecodeIterator,
BytecodeArrayBuilder and Bytecodes::Decode to support 16 bit operands. Adds
support to Interpreter to load 16 bit operands.

Also fixes a bug with ToBoolean where it wouldn't get emitted at the start
of a block, and added a test.

56a0a797f2 Update post-mortem metadata generation
mdb_v8, a post-mortem debugger for Node.js, now uses JSArrayBuffer's
backing_store property and JSArrayBufferView's byte_offset property to
get access to the content of Buffer instances in node (which are
Uint8Array instances). This change adds post-mortem metadata for these
two properties.

This change also fixes a typo in
inobject_properties_of_constructor_function_index_offset that was added
to gen-postmortem-metadata in a previous change. It should be named
inobject_properties_or_constructor_function_index instead.

5d954d6506 [turbofan] Deferred blocks splintering.
This change encompasses what is necessary to enable stack checks in loops without suffering large regressions.

Primarily, it consists of a new mechanism for dealing with deferred blocks by "splintering", rather than splitting, inside deferred blocks.

My initial change was splitting along deferred block boundaries, but the regression introduced by stackchecks wasn't resolved conclusively. After investigation, it appears that just splitting ranges along cold block boundaries leads to a greater opportunity for moves on the hot path, hence the suboptimal outcome.

The alternative "splinters" ranges rather than splitting them. While splitting creates 2 ranges and links them (parent-child), in contrast, splintering creates a new independent range with no parent-child relation to the original. The original range appears as if it has a liveness hole in the place of the splintered one. All thus obtained ranges are then register allocated with no change to the register allocator.

The splinters (cold blocks) do not conflict with the hot path ranges, by construction. The hot path ones have less pressure to split, because we remove a source of conflicts. After allocation, we merge the splinters back to their original ranges and continue the pipeline. We leverage the previous changes made for deferred blocks (determining where to spill, for example).

cbbaf9ea6a [turbofan] Unify referencing of stack slots
Previously, it was not possible to specify StackSlotOperands for all
slots in both the caller and callee stacks. Specifically, the region
of the callee's stack including the saved return address, frame
pointer, function pointer and context pointer could not be addressed
by the register allocator/gap resolver.

In preparation for better tail call support, which will use the gap
resolver to reconcile outgoing parameters, this change makes it
possible to address all slots on the stack, because slots in the
previously inaccessible dead zone may become parameter slots for
outgoing tail calls. All caller stack slots are accessible as they
were before, with slot -1 corresponding to the last stack
parameter. Stack slot indices >= 0 access the callee stack, with slot
0 corresponding to the callee's saved return address, 1 corresponding
to the saved frame pointer, 2 corresponding to the current function
context, 3 corresponding to the frame marker/JSFunction, and slots 4
and above corresponding to spill slots.

The following changes were specifically	needed:

* Frame	has been changed to explicitly manage three areas of the
  callee frame, the fixed header, the spill slot area, and the
  callee-saved register area.
* Conversions from stack slot indices to fp offsets all now go through
  a common bottleneck: OptimizedFrame::StackSlotOffsetRelativeToFp
* The generation of deoptimization translation tables has been changed
  to support the new stack slot indexing scheme. Crankshaft, which
  doesn't support the new slot numbering in its register allocator,
  must adapt the indexes when creating translation tables.
* Callee-saved parameters are now kept below spill slots, not above,
  to support saving only the optimal set of used registers, which is
  only known after register allocation is finished and spill slots
  have been allocated.

1b1de2d221 Make run-tests.py warn when it's not testing anything
I've often been confused by an "all passed" run of the test script
when it turned out that either all the tests I cared about were skipped
or, more likely, I mistyped the name(s) of the tests I wanted to run.
This patch aims to fix that (and gives a useful diagnostic for the
"all matched tests were skipped" case).

Use the same path separator for test cases on the cmd-line
on all platforms as in testcase.GetLabel, which is used to

0a1a714f7e Introduce object visitor to estimate the size of a native context.
This is only an estimate since it counts objects that could be shared,
for example strings, cow arrays, heap numbers, etc.

It however ignores objects that could be shared, but may only be used
by the context to be measured, for example shared function infos,
script objects, scope infos, etc.

2e4efcfac2 Add a --harmony-object-observe runtime flag (on by default)
To avoid tanking context startup performance, only the actual installation of the
JS-exposed API is flag-guarded. The remainder of the implementation still
resides in the snapshot.

c11ab6f7e5 Setting up the stage for heuristics that preprocess live ranges before register allocation, and are independent of register allocation - e.g. the deferred blocks heuristic, or the split at call sites heuristic.
Added a separate flag for this, since we intend to enable it for the linear allocator as well. Currently, the option is "on" for greedy, as a point in time to enable its testing (through the greedy allocator bots).

6ab1f70e12 [Intepreter] BytecodeArrayBuilder and accumulator based bytecodes.
The BytecodeArrayBuilder has responsibility for emitting the BytecodeArray. It will be used by the AST walker.

Bytecode now uses an accumulator plus registers rather being pure register based.

Update BytecodeArray::Disassemble to print operand information.

c215c9569e [turbofan] Factor C call descriptor building into compiler/c-linkage.cc.
This is the first step in cutting the Gordian linkage/linkage-impl knot.

This basically changes the axis along which we organize call descriptor
building logic from having platform-specific files dedicated to all call
descriptor types to having call-descriptor-type-specific files that have

The next step is to factor the JS, code stub, and runtime call descriptors
similarly, dumping them into:
  compiler/js-linkage.cc
  compiler/runtime-linkage.cc
  compiler/code-stub-linkage.cc

 or, alternatively, all of them just into compiler/js-linkage.cc.

This also anticipates a wasm-linkage.cc file in the future.
