df6029f5a9 [cleanup] Removing GraphBuilderTester class
GraphBuilderTester was introduced at a time where RawMachineAssembler
was going to be deprecated (https://codereview.chromium.org/1423923003/).
Now we know that it's not going to happen any time soon.

Since GraphBuilderTester it's only used in one test which can use
RawMachineAssembler, I updated it and removed the class.

Now the .h file had another class, which is now the only class in the file.
Therefore, I renamed it and updated the include calls to it.

Also updated the include commands: some were not necessary, and some others
could be moved to more aptly places.

4b0f9c856e [cleanup] Use Vector::begin instead of Vector::start
Our {Vector} template provides both {start} and {begin} methods. They
return exactly the same value. Since the {begin} method is needed for
iteration, and is also what standard containers provide, this CL
switches all uses of the {start} method to use {begin} instead.

Patchset 1 was auto-generated by using this clang AST matcher:
    callExpr(
        callee(
          cxxMethodDecl(
            hasName("start"),
            ofClass(hasName("v8::internal::Vector")))
        ),
        argumentCountIs(0))

Patchset 2 was created by running clang-format. Patchset 3 then
removes the now unused {Vector::start} method.

3cd6705f58 [wasm][x64] Use near jump in jump table
On x64, we allocate one big code region such that we can use near jumps
and near calls. The jump table did not make use of that design yet.
This CL changes that by emitting jump table slots as near jumps. This
also speeds up patching jump table slots significantly, since far jumps
populate the inline constant pool, which is unneeded overhead in this
case.
As a drive-by, this CL cleans up the API of near_call and near_jmp. The
current semantics is broken, and only works because this is only used
for WebAssembly calls which are patched anyway after code generation.
Also, x64 now uses the same path in test-jump-table-assembler.cc as
arm64 to ensure that all targets are within near-call-distance.

9010424ff5 Reland "[wasm] Implement table.init for interpreter"
This is a reland of 63608968b6

The previous CL failed on Windows, but it was a general bug. The
dropped_elem_segments was not being set on the instance properly in
cctests, so`table.init` instructions would fail by reading uninitialized
data.

I took this opportunity to also add an implementation of
`elem.drop` in the interpreter, and ported the JS tests for those too.

> [wasm] Implement table.init for interpreter
>
> This also fixes CheckCallViaJS when a trap occurs. In that case, the
> trap callback is called instead of an exception being thrown, so if it

2b7fdbfc75 [wasm] Fix lifetime of reference values on interpreter stack.
This ensures the lifetime of reference values on the simulated operand
stack of the interpreter is coupled to a lifetime of the {ThreadImpl}.
We no longer directly store reference values on the stack, but maintain
a separate "reference stack" on the GC'ed heap. This will ensure the GC
traces such references properly.

The new {StackValue} safety wrapper makes sure all use-sites that access
the operand stack properly convert to/from handles when dealing with
reference values.

46a99b07fc [wasm] Add support for "br_on_exn" in the interpreter.
This adds preliminary support for handling the "br_on_exn" opcode in the
interpreter. It also makes "catch" and "rethrow" use a proper exception
reference instead of a dummy value.

To that end this also adds {Handle<>} as a new kind of {WasmValue} which
is intended to pass reference values (e.g. "anyref" or "except_ref") to
the runtime system. Therefore lifetime of such a {WasmValue} is directly
coupled to any surrounding {HandleScope}.

For now we just store {Handle<>} directly on the simulated operand stack
of the interpreter. This is of course bogus, since the surrounding scope
does not outlive the interpreter activation. Decoupling the lifetime of
the operand stack from a {HandleScope} will be done in a follow-up CL.

As a drive-by this change also implements support for the "ref_null" and
the "ref_is_null" opcodes as a proof-of-concept that the new {WasmValue}
is also applicable to the "anyref" reference type.

Both js-to-wasm-wrapper-cache-inl.h and wasm-import-wrapper-cache-inl.h
do not include any inl headers, thus they can be plain headers. If they
ever need to include inl headers again, we should split out the
respective functions into a separete inl header to follow the usual
pattern to have *both* a plain header *and* an inl header.

2d9ec0a420 Reland: [wasm][anyref] Add support of call-indirect for multiple tables
The reason for the revert was that Liftoff did not bail out on indirect
calls to tables other than table 0. Whenever the Liftoff code got
executed, the test would fail.

Original message:
With this CL it is possible to use any anyfunc table in call-indirect,
not just the first table.

The current implementation is based on runtime calls. This is just an
initial implementation which should be replaced by a
dispatch-table-based eventually. However, this implementation allows
us to move forward with the anyref proposal implementation.

1a88414c41 [wasm] Call through dispatch table in interpreter
When running wasm tests, the interpreter previously used a static
collection of function indexes stored in WasmTable to perform
call_indirect calls internal to that module. This has the wrong behavior
if the table is changed (via WasmTableObject::Set, `table.copy`, or
`table.init`).

This CL changes the cctests to always generate an intepreter entry for
all functions, and stores those entries in the dispatch table. This
allows us to use the same execution path as for non-testing code.

The interpreter entry compiler needed to be changed to support
multi-value returns too, since a 64-bit integer return value may be
lowered to two 32-bit integer returns.

25d8a157b1 [wasm] Split adding code from publishing it
This prepares a refactoring to add and publish compilation results in
batches. For this, we need to separate the two phases, so that we can
lock the module, allocate all the code space, release the lock, copy
the code, lock the module, publish the code, and release the lock
again.
In particular, this CL does the following:
1) It removes the {AddOwnedCode} method. The functionality of creating
   the {WasmCode} and memcpy'ing the instruction into that is done in
   the other {Add*Code} methods. Adding to {owned_code_} is done in
   {PublishCode}.
2) {PublishInterpreterEntry} is now functionally equivalent to
   {PublishCode}, so it's removed.
3) After {AddCode}, the caller has to call {PublishCode}. In a
   follow-up CL, this will be called in batches (first {AddCode} them
   all, then {PublishCode} them all).
4) {AddCompiledCode} now assumes that the {WasmCompilationResult}
   succeeded. Otherwise, the caller should directly call {SetError} on
   the {CompilationState}.
5) {PublishCode} is now the chokepoint for installing code to the code
   table, the owned code vector, the jump table, and setting interpreter
   redirections. It replaces previous direct calls to {InstallCode} or
   explicitly adding to {owned_code_}.
6) Increasing the {generated_code_size_} counter is now done in
   {AllocateForCode}, which is the chokepoint for allocating space for
   generated code. This way, we will only increase this counter once
   once we allocate in batches.

ea9e5a7664 [wasm] Rename CheckCallViaJS with argument array
WasmRunner provides CheckCallViaJS, which calls a wasm function through
JS and checks its result.

There are currently two overloads, one that takes a variable number of
arguments, and another more general 4-argument version that takes an
array of arguments. This means if you run code like:

    r.CheckCallViaJS(0, 0, 0, 0);

The overload resolution kicks in, and chooses the general version, which
will always segfault.

This CL renames the general version to `CheckCallApplyViaJS` so the
above example will call the variable-argument version instead.

3df442d738 [wasm] Keep NativeModule alive in BackgroundCompileScope
We need to ensure that the NativeModule stays alive while any
{BackgroundCompileScope} exists, because during that time we hold
shared ownership of the mutex in the {BackgroundCompileToken}. If the
{NativeModule} dies during that period, we would need to get exclusive
ownership of the mutex and deadlock.

This change requires holding a {std::weak_ptr<NativeModule>} in the
BackgroundCompileToken instead of a raw pointer, hence it can only be
initialized after the NativeModule was created. This is done via a
separate {InitCompilationState} method.

dd23f2f316 [wasm][interpreter] Support calls to imported JS functions in cctests
The interpreter is set up specially in cctests to allow more direct
testing. This requires sometimes to write special testing code in the
interpreter which is different than production code. This CL fixes one
instance of testing code which deals with indirect calls.

In production code, indirect calls go through the indirect function
table which can change over time. In cctests, however, the indirect
function table is not set up completely. In cctests the interpreter
uses information from the module instead to acquire the target of an
indirect call. In that testing code, calls to imported JS functions
were not handled. This handling gets added with this CL.

it is not possible to reserve the maximum, fall back to initial size

4c65986a44 [heap] Rework incremental marking scheduling
The new scheduling reduces the main thread marking performed in
tasks and on allocation. It is based on two counters:
- bytes_marked,
- scheduled_bytes_to_mark.

The bytes_marked accounts marking done both the main thread and
the concurrent threads. The scheduled_bytes_to_mark increases based
on allocated bytes and also based on time passed since the start
of marking. The main thread steps are allowed to mark the minimal
amount if bytes_marked is greater than scheduled_bytes_to_mark.

This also changes tasks posted for marking. Before only normal
tasks were posted. Now delayed tasks are posted if the marker is
ahead of schedule.

f0d69fc913 [test] Modernize value helpers
This CL changes the usage pattern from
FOR_XXX_VALUES(i) { Use(*i); }
to
FOR_XXX_VALUES(i) { Use(i); }
which is way more intuitive.

Note that the replacement in the uses was done via regular expression,
so it's purely mechanical. In two locations I removed unneeded braces
around the macro, because they confused clang-format.
I plan to do more cleanups (remove redundant assignments within the
FOR_XXX_VALUES body) in a follow-up CL.

258371bd44 [wasm][anyref] Support anyref stack parameters
Anyref parameters can exist across GC runs. Therefore the GC has to
know where anyref parameters are on the stack so that it can mark them
in its marking phase, and update them in the compaction phase.

Already in a previous CL we grouped all anyref parameters so that they
can be found more easily in a stack frame, see
https://crrev.com/c/1371827. In this CL we implement the stack scanning
itself.

Note that anyref parameters are not scanned while iterating over the
caller's frame (to which they actually belong), but while iterating
over the callee's frame. The reason is that with tail-calls, only the
callee knows how many tagged stack parameters (aka anyref parameters)
there are.

a1ff298d4f [wasm] Move Isolate management to WasmEngine
The WasmCodeManager held a list of all Isolates that use the
WasmEngine/WasmCodeManager (those two are 1:1).
Since we want to move all isolate-specific tasks (like code logging and
compilation callbacks) to the WasmEngine, this CL moves this management
from the WasmCodeManager to the WasmEngine. We now have a bidirectional
mapping from NativeModules to the Isolates that use them, and from an
Isolate to all the NativeModules it uses (n:n).
The IsolateData struct will be extended in follow-up CLs to hold things
like the ForegroundTaskRunner. The Isolate* in the NativeModule /
CompilationState will eventually be removed.

4e1d7c87b9 [wasm] Split compilation in three stages
In order to refactor ownership between objects in wasm compilation, the
compilation (executed by background tasks) is split in three stages:
getting a compilation unit (while holding a mutex), executing the work
(without any mutex and without keeping the NativeModule alive), and
submitting the work (with a mutex again).

This CL prepares this design by splitting compilation from submission.
Both steps are still executed right after each other. This will be
changed in a follow-up CL.

ccc068d5fd [nojit] Skip the on-heap trampoline for builtin calls
This CL does two things:

1. It introduces Call/JumpCodeObject as the bottleneck for all calls
   to non-heap-constant Code objects; and
2. it dispatches directly to the off-heap entry point for all embedded
   code.

Codegen at runtime remains unchanged to preserve the shorter,
branch-less calling sequence.

f68ee6e7e4 [typedarrays] Use Detach instead of Neuter
This is purely a renaming change. The ES spec uses the term 'detach'
for the process of removing the backing store of a typed array, while
V8 uses the historical term 'neuter'. Update our internal implementation,
including method names and flag names, to match the spec.

Note that some error messages still use the term 'neuter' since error
messages are asserted by some embedder tests, like layout tests.

Instead of the WasmModuleObject, it now receives the new

Some classes are pulled out of WasmModuleObject to allow reuse.

We need to be able to serialize a NativeModule, which is not bound to
any Isolate. Hence we should not want to pass any Isolate to the
serializer. This CL removes the dependence by not using the
ExternalReferenceTable from the Isolate, but instead using its own
ExternalReferenceList for serialization and deserialization. This
ExternalReferenceList only contains isolate-independent external
references.

36243360a7 Make cctest/test-jump-table-assembler/JumpTablePatchingStress reliable on Arm64.
The test was flaky because it assumed that AllocatedAssemblerBuffer
would eventually return an address within near-call range. Rarely, this
did not happen (within the retry limit), and so the test would crash.

This fix allocates a single, kMaxWasmCodeMemory-sized buffer for the
test, and generates call sequences within that buffer.

014d9e4f32 [wasm] Decouple wire bytes from compilation units
Compilation units currently contain pointers into allocated space that
contains the code of the respective function. This requires us to keep
the StreamingDecoder alive as long as compilation is still running
(including tiering).
This CL refactors this by having an additional redirection
(WireBytesStorage) which can point to either the StreamingDecoder or
the NativeModule. We only keep the code section buffer alive as long as
the StreamingWireBytesStorage is still in use.

I will further refactor memory ownership in a follow-up CL to not make
the AsyncCompileJob keep the StreamingDecoder alive.

9392727982 [ubsan] Replace Object** in GlobalHandles
as part of the continuing quest to get rid of Object*/Object** entirely.
Since it fits nicely, this CL as a bonus includes the planned change to
make Handle::location() return an Address*, in the process dropping the
temporarily needed duplicate Handle::location_as_address_ptr().

cc70a6b050 [wasm] Rename GrowMemory to MemoryGrow
The "grow_memory" opcode was renamed to "memory.grow", and the spec
repo was updated to use kExprMemoryGrow internally instead of
kExprGrowMemory (https://github.com/WebAssembly/spec/pull/720).
This CL does the same change for v8.

Drive-by: Rename "current_size" to "memory.size", and a minor cleanup
in wasm-graph-builder.js to bring it in line with the version in the
js-api tests in the spec repo.

a2b3480611 [wasm] Use a tuple as the instance for JS imports
This CL refactors the implementation of WASM->JS import wrappers in order
to make the wrapper code shareable. Instead of specializing to the import
index, we use a tuple as the object ref in the both the import and indirect
tables. The tuple allows the wrapper code to load both the calling
instance and the target callable, rather than relying on code specialization.

This requires some tricky codegen machinery, because WASM call descriptors
expect an instance argument in a given register, yet the wrappers receive
a tuple, the code generator must generate a prologue that loads the
instance (and the callable), since it is not possible to express this at
the graph level.
