abad9b2ff9 [Interpreter] Add IsInterpreted() to JSFunction and use to fix test-heap tests.
Adds an IsInterpreted() function to both SharedFunctionInfo and JSFunction.
This is used to fix the test-heap code-aging tests since Ignition doesn't
age code.

b4b436de6a [compiler] Ship Ignition for all TurboFan code.
This enables Ignition unconditionally for all code that is destined for
optimization with TurboFan. This ensures all optimization attempts will
go through the BytecodeGraphBuilder and that the AstGraphBuilder pipe is
dried out in practice.

The CL #39795 (https://codereview.chromium.org/2345593003 ) added MultiReturnSelect_f32/MultiReturnSelect_f64 tests.
  Because those tests need 2 float point return registers and x87 only has 1 FP return register, Those tests failed at x87 port.

  This CL skips MultiReturnSelect_f32/MultiReturnSelect_f64 tests for x87.

245e5b323c [Ignition] Use binary operation feedback from Ignition to Crankshaft.
Ignition collects type feedback for binary and compare operations in type
feedback vector and FCG uses Binary/CompareOpICs to collect type feedback.
The feedback collected by ignition is not used by crankshaft. This hits the
performance, when trying to optimize functions that did not tier upto FCG.
This cl merges the feedback collected by ignition and FCG when passing to
crankshaft.

cf127e8144 [modules] Expand API to allow linking and use it in d8
This patch gives the ability for the embedder to ask for the
module requests of a module, and to pass a ResolveCallback
into Module::Instantiate().

In d8, I've implemented a simple module_map that's used
along with this API to allow loading, compiling, instantiating,
and evaluating a whole tree of modules.

No path resolution is yet implemented, meaning that all
import paths are relative to whatever directory d8 runs
in. And no imports are linked to the exports of the
requested module.

17e9e2f4c8 Forking the type system between Crankshaft & Turbofan.
Our Type class has a semantic and representational dimension.
Much code in src/ast, Crankshaft and Turbofan is based on it.
Going forward in Turbofan we'd like to remove representational information
entirely. To that end, new type AstType has been created to preserve
existing behavior for the benefit of Crankshaft and the AST.

f676db4655 [turbofan] Lazy bailout for calls doesn't need callee.
There's no need to preserve the exact callee for lazy bailouts
from JSCallFunction in the AstGraphBuilder, as fullcodegen code
will never look at that value after the callee returns. So we
just push optimized_out instead.

03f5124822 [test] Enable test status filtering by variant
This adds the possibility to address test cases in the
status file with the variant under which the test is running.
This is only allowed in top-level sections.

Example:
[{
  'test-case': [PASS, SLOW],
}]

['variant == foo', {
  'test-case': [FAIL],
}]

The test case "test-case" is marked as slow in all variants.
Additionally, in variant foo, it'll be expected to fail.

This CL also exemplifies the new feature with test cases
running under the ignition_turbofan variant. The
corresponding legacy flag is deprecated.

This allows to pass deoptimization reasons to the profiler without the
requirement of always providing a source position. The absence of deopt
reasons is now communicated via a sentinel as the deopt id value. The
deoptimization reasons recently added to TurboFan are now passed to the

bf4ef548cc X87: disable test-gap-resolver/FuzzResolver test case for x87.
The reason:
  In CreateRandomOperand(), It used the register index 1 for ExplicitOperand(LocationOperand::REGISTER, rep,
  GetRegisterCode(rep, 1)).

  For x87 turbofan compiler, there's only 1 allocatable Float/Double register, i.e.: register index 0. the
  GetRegisterCode(rep, 1) in ExplicitOperand() always return false when rep is MachineRepresentation::kFloat32/kFloat64.

  It caused the test-gap-resolver/FuzzResolver failed at DCHECK_IMPLIES(kind == REGISTER && rep == MachineRepresentation::kFloat32,
  FloatRegister::from_code(index).IsAllocatable(RegisterConfiguration::TURBOFAN)), src/compiler/instruction.cc, line 259, under
  debug mode.

  This CL disable test-gap-resolver/FuzzResolver test case for x87.

Reland of https://codereview.chromium.org/2034093002 (reverted by
https://codereview.chromium.org/2080153002).

Original commit message:
Implement WASM support on big-endian platforms. WASM has
an implicit requirement that it is running on little-endian
machine. We achieve WASM support on BE by keeping data
in memory in little-endian order, and changing data
endianness before storing to memory and after loading from
memory.

9a9ffd1370 X87: disable some sin/cos/expm1/tan test cases for x87.
The reason:
  All RunFloat64Sin/RunFloat64Cos/RunFloat64Expm1/RunFloat64Tan/Ieee754.Expm1/Ieee754.Cos/Ieee754.Tan test cases
  use the C++ function to generate the expected value or result. So for x87, all those expected value or result are
  extended double precision as the extended double precision is default for x87 Gcc compiler and std lib on linux platform.

  The issue is:
  For RunFloat64Sin/RunFloat64Cos/RunFloat64Expm1/RunFloat64Tan test cases, the expected values generated by C++ function
  are extended double precision, the results generated by X87 jitted code are double precision according to the ECMA standard.
  The comparison of different precisons caused some of those test cases failed.

  For Ieee754.Expm1/Ieee754.Cos/Ieee754.Tan test cases, the expected values are pre-defined double precision values, the results
  generated by C++ function are extended double precision. The comparison of different precisons caused some of those test cases
  failed too.

  This CL disables RunFloat64Sin/RunFloat64Cos/RunFloat64Expm1/RunFloat64Tan/Ieee754.Expm1/Ieee754.Cos/Ieee754.Tan test cases for x87.

40f345416f [Interpreter] Fix incorrect frame walking in arguments create stubs
The previous approach taken by FastNew[Sloppy,Strict,Rest]ArgumentsStub
looked at the function slot in order to skip stub frames
and find the JS frame. However, stub frames do not have a
function slot (in fact their fixed frame ends one slot
before the JS frame's function slot). Therefore, if this
location in the stub frame happens to have the function
object the create arguments stubs won't skip this frame
correctly.

Replace this approach with one where the stub is
specialized to either skip a frame if required (since
there will only ever be one extra frame on Ignition
the loop approach isn't necessary).

6e8958fff4 [serializer] ensure that immortal immovable roots are correctly deserialized.
Immortal immovable roots must be allocated on the first page of the space.
If serializing the root list exceeds the first page, immortal immovable root
objects might end up outside of the first page. That could cause missing
write barriers.

We now iterate the root list twice. The first time we only serialize immortal
immovable root objects. The second time we serialize the rest.

This change removes the first of those, updates unit tests,

---
An alternative would be to emulate the existing behaviour in Ignition, but:
- The new behaviour seems more logical,
- Ignition generates no bytecodes for the 'var', meaning there is no code position to attach the break position to.

e906c9caef X87: Disable the test-run-profiler/Inlining test case for X87.
The CL #34376 (https://codereview.chromium.org/1740073002 ) added the Inlining test case and X87 failed at it.

  The reason is:
  For TEST(Inlining) test case, when level3 function is inlined, the key optimized crankshaft code will like below code normally:
  ............
  0x21d53b7f    63  ff571b         call [edi+0x1b]           <-----------  should call action() here
                    ;;; <@32,#27> lazy-bailout
                    ;;; <@36,#31> ---- B3 ----
                    ;;; <@37,#31> gap
  0x21d53b82    66  89c1           mov ecx,eax               <-----------  Both the inlined function’s pc_offset from DeoptimizationInputData and the pc_offset from sample stack points to here, the same pc address
  ............

  So the TEST(Inlining) test case can get the expected inlined code entry and pass..

  In fact, the exact code sequence should like the following in crankshaft:
  ............
  0x21d53b7f    63  ff571b         call [edi+0x1b]                 <-----------  should call action()
  0xxxxxxxxx    xxxx               GenerateBodyInstructionPost()   <-----------  the pc_offset from sample stack points to here
                    ;;; <@32,#27> lazy-bailout
                    ;;; <@36,#31> ---- B3 ----
                    ;;; <@37,#31> gap
  0x21d53b82    66  89c1           mov ecx,eax                     <-----------  the inlined function’s pc_offset from DeoptimizationInputData points to here.
  ............

  For most of architectures in V8, the GenerateBodyInstructionPost()  is empty, so both the inlined function’s pc_offset from DeoptimizationInputData and the pc_offset from sample stack points to  the same pc address .

  But if some architecture has special requirement and need to put some instruction after call instruction, the GenerateBodyInstructionPost() will do that work and generate instructions,  the inlined function’s pc_offset from DeoptimizationInputData and The pc_offset  from sample stack will points to  the different  pc address, the TEST(Inlining) test case can’t get the expected inlined code entry and failed.

  For all current architectures in v8, only x87 have this requirement.

  After communicated with Alexei Filippov <alph@chromium.org> in E-mail, we decided to disable the Inlining test case for x87 now and try to find a solution.

dbf5fffd2d [Interpreter] Fixes PushArgsAndConstruct builtin to not store any data outside esp.
In ia32 PushArgsAndConstruct builtin, we run out of registers and need to
temporarily store the data in the stack. In the earlier implementation,
a location outside the esp was used. This causes a problem if there is a
interrupt/signals which would use the same stack and corrupt the data that
is above the esp. This cl fixes it by pushing it onto the stack so that
the stack pointer is updated and hence the corruption will not happen. We
reuse the slot meant for receiver as a temporary store.

d9fe836dd4 [debugger] fix break locations for assignments and return.
We used to emit debug break location on block entry. This cannot be
ported to the interpreted as we do not emit bytecode for block entry.
This made no sense to begin with though, but accidentally added
break locations for var declarations.

With this change, the debugger no longer breaks at var declarations
without initialization. This is in accordance with the fact that the
interpreter does not emit bytecode for uninitialized var declarations.

Also fix the bytecode to match full-codegen's behavior wrt return
positions:
- there is a break location before the return statement, with the source
  position of the return statement.
- right before the actual return, there is another break location. The
  source position points to the end of the function.

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.

bb31db3ad6 Type Feedback Vector lives in the closure
(RELAND: the problem before was a missing write barrier for adding the code
entry to the new closure. It's been addressed with a new macro instruction
and test. The only change to this CL is the addition of two calls to
__ RecordWriteCodeEntryField() in the platform CompileLazy builtin.)

We get less "pollution" of type feedback if we have one vector per native
context, rather than one for the whole system. This CL moves the vector
appropriately.

We rely more heavily on the Optimized Code Map in the SharedFunctionInfo. The
vector actually lives in the first slot of the literals array (indeed there is
great commonality between those arrays, they can be thought of as the same
thing). So we make greater effort to ensure there is a valid literals array
after compilation.

This meant, for performance reasons, that we needed to extend
FastNewClosureStub to support creating closures with literals. And ultimately,
it drove us to move the optimized code map lookup out of FastNewClosureStub
and into the compile lazy builtin.

The heap change is trivial so I TBR Hannes for it...
Also, Yang has had a look at the debugger changes already and approved 'em. So he is TBR style too.
And Benedikt reviewed it as well.

cb9b801069 [builtins] Make Math.max and Math.min fast by default.
The previous versions of Math.max and Math.min made it difficult to
optimize those (that's why we already have custom code in Crankshaft),
and due to lack of ideas what to do about the variable number of
arguments, we will probably need to stick in special code in TurboFan
as well; so inlining those builtins is off the table, hence there's no
real advantage in having them around as "not quite JS" with extra work
necessary in the optimizing compilers to still make those builtins
somewhat fast in cases where we cannot inline them (also there's a
tricky deopt loop in Crankshaft related to Math.min and Math.max, but
that will be dealt with later).

So to sum up: Instead of trying to make Math.max and Math.min semi-fast
in the optimizing compilers with weird work-arounds support %_Arguments
%_ArgumentsLength, we do provide the optimal code as native builtins
instead and call it a day (which gives a nice performance boost on some
benchmarks).

a5200f7ed4 Type Feedback Vector lives in the closure
We get less "pollution" of type feedback if we have one vector per native
context, rather than one for the whole system. This CL moves the vector
appropriately.

We rely more heavily on the Optimized Code Map in the SharedFunctionInfo. The
vector actually lives in the first slot of the literals array (indeed there is
great commonality between those arrays, they can be thought of as the same
thing). So we make greater effort to ensure there is a valid literals array
after compilation.

This meant, for performance reasons, that we needed to extend
FastNewClosureStub to support creating closures with literals. And ultimately,
it drove us to move the optimized code map lookup out of FastNewClosureStub
and into the compile lazy builtin.

The heap change is trivial so I TBR Hannes for it...

5736eb0ccb X87: Change the test case for X87 float operations
The CL https://codereview.chromium.org/1409013004 added / changed some test cases.
       Some new test cases use CheckFloatEq(...) and CheckDoubleEq(...) function for result
       check. When GCC compiling the CheckFloatEq() and CheckDoubleEq() function, those inlined
       functions has different behavior comparing with GCC ia32 build and x87 build. The major
       difference is sse float register still has single precision rounding semantic. While X87
       register has no such rounding precsion semantic when directly use register value. The V8
       turbofan JITTed has exactly same result in both X87 and IA32 port.

       So we add the following sentence to do type case to keep the same precision.
          float expect = *i * *j; // *i + *j, etc.

       For test case "RunFloat64MulAndFloat64Add1 / RunFloat64MulAndFloat64Add2 / RunFloat64MulAndFloat64Sub1
       / RunFloat64MulAndFloat64Sub2", the expected result calcaulated by GCC has difference precsion
       when comparing with V8 turbofan result for X87 platform. (Turbofan X87 result is the same as
       IA32 GCC and IA32 Turbofan). So we have to disable those four cases for X87 port.

The callees are expected to properly set the number of actual
arguments passed to the callee, which is now represented correctly
in the TurboFan graphs by a new Parameter right before the context
Parameter.  Currently this is only being used for outgoing calls.

Note that this requires disabling two of the TF code stub tests,
because of the JavaScript graphs are not automagically compatible
with abitrary (incoming) code stub interface descriptors.  If we
want to support JS code stubs at all, then we need to find a sane
way to feed in this information.

40d01b57d9 Mark SizeOfFirstPageIsLargeEnough failing on mips64
The failure was been triggered by turning on --harmony-arrays,
maybe because code size was increased or code was added later
in the bootstrap process. Because it doesn't look like a bug
in anything guarded by --harmony-arrays directly, I'd suggest
shipping the flag and disabling the test on the architectures
where it's been observed to fail. It's already disabled on arm64
and this patch disables it on mips64 as well.

This patch includes the following changes.
     1, Enable the turbofan backend support for X87 platform. It depends on previous CL: 3fdfebd26.
     2, Enable the test cases which are disabled because turbofan for X87 was not enabled.

45e4a78911 Contribution of PowerPC port (continuation of 422063005) - uplevel
Contribution of PowerPC port (continuation of 422063005,
817143002,866843003, and 901083004). This patch updates
the ppc directories to make them current with changes in
common code as of today.

We had to exclude the test test-serialize/SerializeInternalReference
until we agree on the right way to add those changes for PPC as
outlined in the description in the google doc provided earlier.

We also had to exclude a couple of other tests due to new
failures seen since the last uplevel.  We excluded as opposed
to waiting until we could investigate to maximize the chance
of getting PPC compiling in the google repos before new
breaking changes are made.

I'll note that before applying any of our changes the
mozilla part of quickcheck was already broken when using
the lastest repo content so I had to run without that

6f559b7ec3 [turbofan] Fix lazy deopt for JSToNumber conversions in binary operations.
This slightly hacky change provides lazy deopt points for to-number conversions in binops: When we deopt from a to-number conversion, we create a frame state with the already-converted value(s) so that we do not repeat the side effect of the conversion.

a3465838bc Contribution of PowerPC port (continuation of 422063005) - currency
Contribution of PowerPC port (continuation of 422063005, 817143002,
866843003, and 901083004. This patch updates the ppc directories
to make them current with changes in common code, removes the
optimization to use the ool constant pool, and excludes tests that
don't pass under the ppc simulator given a 240s timeout.

Subsequent patches will cover:
   - remaining optimizations for PPC
   - remaining AIX changes not resolved by 4.8 compiler (4.8 is only recently available for AIX)
   - incremental updates required to ppc directories due to platform specific changes made
    in google repos while we complete the above steps.

aeb3a71740 Begin modernization of --harmony-modules
The approach taken in this CL is to incrementally move toward the
currently-specced version of modules in ES6. The biggest change in this
patch is separating the parsing of modules from the parsing of scripts,
getting rid of the 'module' keyword and thus disallowing modules-in-scripts
as well as modules-in-modules.

The syntax supported by import/export declarations has not yet been significantly
changed, with the major exception being that import declarations require a string
as the 'from' part.

Most of the existing tests have been disabled, with a first new test added
in cctest/test-parsing.

87db4ff1f4 Fix/suppress unittests broken on Android
cctest/test-threads/ThreadJoinSelf is suppressed for Android, but the
test has since been moved to unittests/Thread.SelfJoin. Move the
suppression to unittests.status.

unittests/ThreadLocalStorageTest.DoTest fails on older Android devices
as it assumes the availability of more TLS slots than many devices
implement. Test a smaller number of slots (32) on Android. Remove old
suppression of test-platform-tls/FastTLS (which no longer exists).

cctest/test-mark-compact/RegressJoinThreadsOnIsolateDeinit can't deal
with shared mappings. Check for 's' instead of '-'.

e4c6f9488e Implement graph trimming in ControlReducer.
Trimming the graph consists of breaking links from nodes that are not reachable from end to nodes that are reachable from end. Such dead nodes show up in the use lists of the live nodes and though mostly harmless, just clutter up the graph. They also can limit instruction selection opportunities, so it is good to get rid of them.

This CL is one half of the ControlReducer functionality, the other half
being branch folding.
