fdc9fade97 [torque] Enum language feature
This CL implements enums in Torque in three steps:

1.) It implements necessary changes to Torque's type system. In
particular, the constraints on constexpr types are relaxed such that
constexpr types can exist without a corresponding non-constexpr
version. Furthermore, constexpr and their non-constexpr counterpart
need not be of the same kind of type. This allows an AbstractType to
have a UnionType as its non-constexpr counterpart.

2.) The enum feature itself is realized as a pure desugaring in the
parser, where all required types, constants and macro specializations
(like FromConstexpr<>) are generated from a simple enum declaration,
such that enum entries are not just constants, but are namespace
scoped and have distinct types so that they can be used within
typeswitch constructs.

3.) Almost all of the existing constants defined in torque
(.tq files) are ported to new enum definitions.

New revision: 726836d7317a4031f48af9960bab51d7a2ab2867

The gist is that serialization is direct from
protocol objects to CBOR, no more detour via
protocol::Value.

ce3ce2f66d [DevTools] Roll inspector_protocol (V8) (strtod)
New revision: 7a44a37f66b58358dd8ab85ccde1998fafa95e53

Upstream review:
https://chromium-review.googlesource.com/c/deps/inspector_protocol/+/1899564

Previously, we used a wrapper library, v8-inspector-protocol-encoding.h
to inject the string<->number conversion into the cbor parser. This
meant that the unittests, in
third_party/inspector_protocol/crdtp/json_test.cc inadvertently did
not run with the same string<->number conversion code. Thus, we missed
that the production implementation would return INF for out of range
double literals, as opposed to rejecting the incoming JSON.
When switching the library to the build dependency on json_platform_v8.cc
as it's in this change, the test immediately failed which made it
trivial to fix the implementation.

Old implementation:
https://chromium-review.googlesource.com/c/v8/v8/+/1913424/6/src/inspector/v8-inspector-protocol-encoding.cc

New implementation (checks std::isfinite):
https://chromium-review.googlesource.com/c/v8/v8/+/1913424/6/third_party/inspector_protocol/crdtp/json_platform_v8.cc

upstream
https://chromium-review.googlesource.com/c/deps/inspector_protocol/+/1924792
https://chromium-review.googlesource.com/c/deps/inspector_protocol/+/1925679
and does not touch V8 code. Would like to get
this in to make it easier to review subsequent changes.

Thanks!

The Torque formatter script did a hack to put spaces arount the | of
union types. This was broken when the inserted comment ended up on the
end of a line. For this reason, and since it doesn't make sense to
fight the Google-wide TypeScript style for union types, this CL reverts
to not putting spaces around union types.

Host info used to be stored on the global reference underlying a Ref;
now it is stored in a JSWeakMap and hence tied to the lifetime of the
actual object on V8's heap.
Additionally, the internal metadata needed for C-API functions is now
stored on the SharedFunctionInfo and no longer overlaps with the host

Update v8 files / build config accordingly.
- There's now a new library in third_party/inspector_protocol,
  bindings/bindings.h, which is configured much like encoding/encoding.h.
  It doesn't have much stuff in it yet, but will soon get more code
  that would otherwise need to go into jinja templates.
  It also comes with a new test, only a smoke test thus far.

76c1e829e3 [torque] Support 'real' internal classes
Rework the implementation of non-external Torque classes to use
Struct machinery rather than FixedArray machinery. This allows
Torque-only defined 'internal' classes to the automatically generate
class verifiers and printers.

As part of this change, generate C++ boilerplate accessors for
internal Torque classes, since this is a pre-requisite for the
verifiers, printers and other Struct-based functionality.

Moreover, augment the header-generating functionality in Torque
to create separate header files for field offset definitions,
internal class C++ definitions and instance types.

This brings V8 not only in line with the proposed Array#sort spec

throw a TypeError when the new test case is run.

For every @noVerifier in base.tq, this change either removes it or
ensures that it has some annotation explaining why it can't be removed.
The @noVerifier usages that can't be removed fall into the following
categories:
1. Classes that don't have their own instance types and therefore have
   no meaningful way to do an Is...() check
2. Fields that might not exist
3. Fields that are waiting for MaybeObject support in Torque

da6543108d [torque] Add lint error for 'let' bindings that can be 'const'
This CL adds a lint error for variables that are unnecessarily bound
with 'let' when they could be bound using 'const. This test is skipped
for struct types. For struct types, the "constness" also depends on
the struct methods called and whether these methods write to the struct
or not. This is not straight-forward to detect.

Drive-by: Fix all the newly introduced lint errors.

0e53739c39 [torque] Add lint errors for unused variable and label bindings
This CL adds lint errors when 'let' bindings, arguments and labels
are not used. Note that errors for 'const' bindings will be added
later.

In cases where arguments are actually needed to match the signature,
the warning can be silenced by prefixing identifiers with "_". This
might be needed for generic specializations or builtins called from
TurboFan. Trying to use a variable or label that was marked with
"_" results in a compilation error.

Implicit arguments are not linted. They are implemented using exact
string matching. Prefixing an implicit argument with "_" in a callee
would break all callers as the names would no longer match.

Drive-by: Fix all new lint errors in the existing Torque code.

82f6179c63 [array] Prevent negative work array capacity when sorting
When allocating large arrays on 32-bit systems, the length conversion
caused the work array capacity to become negative. As the sort range
is currently clamped at kSmiMaxValue anyway, the fix is to also
clamp the work capacity to that value.

2b0ac2fb9f [array] Move Array#sort pre-processing to Torque
This CL removes the "PrepareElementsForSort" runtime function, and
replaces it with a simpler version in Torque. The biggest difference
is that certain sparse configurations no longer have a fast-path.

The Torque pre-processing step replaces the existing Torque mechanism that
copied already pre-processed elements into the "work" FixedArray. The Torque
compacting works as follows:
  - Iterate all elements from 0 to {length}
    - If the element is the hole: Do nothing.
    - If the element is "undefined": Increment undefined counter.
    - In all other cases, push the element into the "work" FixedArray.

Then the "work" FixedArray is sorted as before. Writing the elements from
the "work" array back into the receiver, after sorting, has three steps:
  1. Copy the sorted elements from the "work" FixedArray to the receiver.
  2. Add previously counted number of "undefined" to the receiver.
  3. Depending on the backing store either delete properties or
     set them to the Hole up to {length}.

a19c3ffb8f Reland: [csa] verify skipped write-barriers in MemoryOptimizer
With very few exceptions, this verifies all skipped write-barriers in
CSA and Torque, showing that the MemoryOptimizer together with some
type information on the stored value are enough to avoid unsafe skipped
write-barriers.

Changes to CSA:
SKIP_WRITE_BARRIER and Store*NoWriteBarrier are verified by the
MemoryOptimizer by default.
Type information about the stored values (TNode<Smi>) is exploited to
safely skip write barriers for stored Smi values.
In some cases, the code is re-structured to make it easier to consume
for the MemoryOptimizer (manual branch and load elimination).

Changes to the MemoryOptimizer:
Improve the MemoryOptimizer to remove write barriers:
- When the store happens to a CSA-generated InnerAllocate, by ignoring
  Bitcasts and additions.
- When the stored value is the HeapConstant of an immortal immovable root.
- When the stored value is a SmiConstant (recognized by BitcastToTaggedSigned).
- Fast C-calls are treated as non-allocating.
- Runtime calls can be white-listed as non-allocating.

Remaining missing cases:
- C++-style iterator loops with inner pointers.
- Inner allocates that are reloaded from a field where they were just stored
  (for example an elements backing store). Load elimination would fix that.
- Safe stored value types that cannot be expressed in CSA (e.g., Smi|Hole).
  We could handle that in Torque.
- Double-aligned allocations, which are not lowered in the MemoryOptimizer
  but in CSA.

Drive-by change: Avoid Smi suffix for StoreFixedArrayElement since this
can be handled by overload resolution (in Torque and C++).

Reland Change: Support pointer compression operands.

5ae5016590 [DevTools] Add unittest for upstream encoding library.
This brings in
third_party/inspector_protocol/encoding/encoding_test.cc
from the upstream project and makes it work for v8's
unittest suite.

encoding_test_helper.h is a V8 specific implementation,
which delegates to src/inspector/v8-string-conversions{.h,.cc},
for the utf8 / utf16 conversion routines.

I'm also fixing / updating roll.py, for future rolls.

This modifies roll.py to update namespaces and header guards.
Also I'm removing --reverse, to avoid making this more complicated.

third_party/encoding/encoding{.h,cc} are already up to date,
since I manually propaged them earlier. So this is why this change
is only updating the template.

9d7c1947f5 [DevTools] Add V8InspectorSession::state(), which returns binary (CBOR).
Keep the existing method for compatibility, by converting
to json from CBOR using the inspector_protocol_encoding library,
via a v8 specific interface library that directs routines for
converting between strings and doubles to v8's implementations.

This change also brings in the encoding.h / encoding.cc files from the
upstream inspector_protocol project. The only modification here
are the header guards, and the namespace. I will fix roll.py to
make it so that we pick up future changes.

third_party/inspector_protocol/BUILD.gn is specific to v8, by necessity.
third_party/inspector_protocol/.clang-format is a copy of the upstream
file. If we don't put this, we'll find ourselves auto-formatting the roll,
which is annoying.

This is a reland of
https://chromium-review.googlesource.com/c/v8/v8/+/1590627 with the
only modification in the DEPS file; this time I'm including
third_party/inspector_protocol/encoding/encoding{.h,cc} in addition to
the relative include there. Not sure why this is needed but I'm hoping
it gets me past the presubmit which may resolve the include path
relative to the V8 base (the ../../third_party is needed for when V8 is
embedded into Chromium).

da7322c05f [csa] verify skipped write-barriers in MemoryOptimizer
With very few exceptions, this verifies all skipped write-barriers in
CSA and Torque, showing that the MemoryOptimizer together with some
type information on the stored value are enough to avoid unsafe skipped
write-barriers.

Changes to CSA:
SKIP_WRITE_BARRIER and Store*NoWriteBarrier are verified by the
MemoryOptimizer by default.
Type information about the stored values (TNode<Smi>) is exploited to
safely skip write barriers for stored Smi values.
In some cases, the code is re-structured to make it easier to consume
for the MemoryOptimizer (manual branch and load elimination).

Changes to the MemoryOptimizer:
Improve the MemoryOptimizer to remove write barriers:
- When the store happens to a CSA-generated InnerAllocate, by ignoring
  Bitcasts and additions.
- When the stored value is the HeapConstant of an immortal immovable root.
- When the stored value is a SmiConstant (recognized by BitcastToTaggedSigned).
- Fast C-calls are treated as non-allocating.
- Runtime calls can be white-listed as non-allocating.

Remaining missing cases:
- C++-style iterator loops with inner pointers.
- Inner allocates that are reloaded from a field where they were just stored
  (for example an elements backing store). Load elimination would fix that.
- Safe stored value types that cannot be expressed in CSA (e.g., Smi|Hole).
  We could handle that in Torque.
- Double-aligned allocations, which are not lowered in the MemoryOptimizer
  but in CSA.

Drive-by change: Avoid Smi suffix for StoreFixedArrayElement since this
can be handled by overload resolution (in Torque and C++).

e87e3b1fa9 [torque] named arguments for constructors
This changes the syntax for constructing structs and classes to explicitly
mention the fieldnames, similar to JavaScript object literals.
The fields still have to be listed in the same order as in the struct/class
declaration.
As in Javascript, {foo: foo} can be abbreviated as {foo}.

Example:

macro NewJSArray(implicit context: Context)(
    map: Map, elements: FixedArrayBase): JSArray {
  return new JSArray{
    map,
    properties_or_hash: kEmptyFixedArray,
    elements,
    length: elements.length
  };
}

Drive-by cleanup: Make struct and class constructors follow the same pattern
                  in the parser and the AST.

With the recent changes to Array#sort, the main algorithm does not
need to bail out anymore. Only the initial copying into the workarray,
as well as the final copying back into the original backing store
might cause a switch from fast-path to the slow-path.

This CL changes the slow-path so sorting itself is not restarted and
the slow-path will continue copying where the fast-path left off.

e7d414a2b6 [array] Eagerly copy elements into a FixedArray for sorting
This CL changes Array#sort to work roughly like:
    1) Call [[Get]] on the receiver in [0, length) and store to FA
    2) Use the existing TimSort to sort that FA
    3) Call [[Set]] on the receiver in [0, length) using the result

This has the advantage that we no longer need different fast-paths
for the sorting algorithm itself, only for step 1 and 3. This results
in a code size reduction of ~2650 bytes.

This CL does not include optimizations that elides step 1 or 3.
