CodeAssembler::Parameter now takes a Type template parameter and
performs a checked cast to it. There is also UncheckedParameter which
returns a TNode but doesn't check the cast. The original Parameter
method is still there as UntypedParameter.
Parameter<T>(x) in many cases replaces CAST(Parameter(x)), where the
cast is performed inside Parameter. Since Parameter is not a macro,
this means it cannot see the original expression or its file name and
line number. So the error messages are vaguely useful, Parameter<T>()
takes a SourceLocation parameter which with a default value of
SourceLocation::Current(), which at least gives us the file name and
line number for the error message.

For cross-thread handling we require the atomic marking pause to

This is ensured by locking the whole atomic pause from entering to
weak processing.
This CL move ProcessWeakness() into FinishMarking() which allows to
nicely scope the upcomming lock from EnterAtomicPause() to
LeaveAtomicPause(). The alternative is requiring the caller to ensure
proper locking which is harder than ensuring that the Marker is

However, the reindexer was incorrectly assuming that all properties
with a FunctionLiteral value are methods (and thus not fields, and
can safely be visited). This is not the case for fields with

Now, we correctly use the class property's "kind" when making this

All instantiations of the function body decoder (validation, Liftoff,
TurboFan) currently generate precise error messages. For Liftoff though,
the error message and location is never used. Thus we can save some
binary size and performance by only keeping a flag whether an error
occured or not. In the error case, the TurboFan compiler will execute
right afterwards anyway, generating a proper error message.
As as follow-up, we can avoid storing the pc in {ValueBase} and
{ControlBase}, because that's only used for error reporting.

This patch removes the concept of reservations and a specialized
deserializer allocator, and instead makes the deserializer allocate
directly with the Heap's Allocate method.
The major consequence of this is that the GC can now run during
deserialization, which means that:
a) Deserialized objects are visible to the GC, and
b) Objects that the deserializer/deserialized objects point to can
move.
Point a) is mostly not a problem due to previous work in making
deserialized objects "GC valid", i.e. making sure that they have a valid
size before any subsequent allocation/safepoint. We now additionally
have to initialize the allocated space with a valid tagged value -- this
is a magic Smi value to keep "uninitialized" checks simple.
Point b) is solved by Handlifying the deserializer. This involves
changing any vectors of objects into vectors of Handles, and any object
keyed map into an IdentityMap (we can't use Handles as keys because
the object's address is no longer a stable hash).
Back-references can no longer be direct chunk offsets, so instead the
deserializer stores a Handle to each deserialized object, and the
backreference is an index into this handle array. This encoding could
be optimized in the future with e.g. a second pass over the serialized
array which emits a different bytecode for objects that are and aren't
back-referenced.
Additionally, the slot-walk over objects to initialize them can no
longer use absolute slot offsets, as again an object may move and its
slot address would become invalid. Now, slots are walked as relative
offsets to a Handle to the object, or as absolute slots for the case of
root pointers. A concept of "slot accessor" is introduced to share the
code between these two modes, and writing the slot (including write
barriers) is abstracted into this accessor.
Finally, the Code body walk is modified to deserialize all objects
referred to by RelocInfos before doing the RelocInfo walk itself. This
is because RelocInfoIterator uses raw pointers, so we cannot allocate
during a RelocInfo walk.
As a drive-by, the VariableRawData bytecode is tweaked to use tagged
size rather than byte size -- the size is expected to be tagged-aligned
anyway, so now we get an extra few bits in the size encoding.

The infrastructure will soon start using the canonical build output
location out/build. New flake bisect jobs will then be started with
--outdir=out/build.
This change picks the current out/Release or out/Debug as an
alternative output location to be compatible with the future value
of the flag.
This code will be removed when the property change happens.
This prepares:

Previously, unhandled promise rejections weren't reset between REPRL
executions, leading to incorrect exit statuses being reported. This CL
fixes the issue and adds further tests to verify the correct behaviour.

When building the error message for a TypeError when e.g.
a non-callable is called, we should avoid running into the
max string length. Printing many megabytes there isn't going
to be useful anyway.

As a preparation to add a "boolean validation" mode, rename the existing
flags. This removes many unrelated changes from the follow-up change and
makes it easier to review.

This breaks looking for build output after finding valid output.
Otherwise build output with lower precedence can overwrite output
with higher precedence.
This also moves a static method.

The invocation count is part of call feedback, and is used during
tier-up to determine inlining candidates. For bytecode, it is updated
by the InterpreterEntryTrampoline, which can be seen as a global
prologue for all bytecode functions.
Since NCI tiers up, it must also track the invocation count. This CL
adds it to the NCI prologue sequence (emitted as part of every NCI
code object).
