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.

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.

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.

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.

as well as the final copying back into the original backing store
might cause a switch from fast-path to the slow-path.

Constructors have been removed. Initialization syntax with {}
for structs and classes is now limited to the initialization
expressions for the fields, so "constructors" deviating from
that explicit and complete list of field initialization
values must be declared as separate macros.

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.

Intrinsic changes:
- Rename %RawCast to %RawObjectCast and add error checking so that it
only applies to subtypes of Objects.
- Add %RawPointerCast, which is similar to %RawObjectCast but must be
used for all subtypes of RawPtr.
- Add %RawConstexprCast, which allows one constexpr to be be cast to
another at compile time. It translate to an appropriate static_cast
in the generated code
- Add %FromConstexpr, which handles most of the standard cases of
generating XXXConstant CSA nodes from constexpr constants. It uses
either SmiConstant, NumberConstant, StringConstant, IntPtrConstant
or Int32Constant, depending on the cast-to type generic <To> type.
- Add support for intrinsics that return constexpr results.
Cleanup:
- Turn FromConstexpr into a generic with two generic types, a <To> and
a <From> type. Most FromConstexpr can use the new %FromConstexpr
intrinsic rather than provide an explicit implementation.

The array length is modifiable by user code that is called as a
side-effect during the sorting algorithm. We thus cannot base any
guarantees on the current length, but must reference the initially-read
array length instead.
Note that even though the algorithm may read and write from beyond
the current array length value, this adheres to the spec, which only
requires accesses to be within the original array dimensions (i.e.: 0
<= i < original array length).

The implicit parameter syntax adds a second parameter list
before the explicit parameter list when declaring macros, builtins and
runtime functions:
extern macro MyMacro(implicit a: Smi)(b: Oddball);
when calling the macro, only the formal parameters can be provided
at the call site. The implicit parameters are implicitly looked-up
by name in the scope of the call and prepended to the explicit parameter
list. The values that are found by name for each implicit parameter must
be castable the corresponding implicit parameter type:
MyMacro(Null); // Error, a is not defined
...
const a: Smi = 0;
MyMacro(Null); // OK
...
const a: Object = 0;
MyMacro(Null); // Error, a has wrong type
For external macros, builtins and runtime functions, the formal
parameter list expected on the C++ side is the concatenation of the
implicit and explicit parameter lists.
As a drive-by: fix the formatting of typeswitch statements in the
the presence of deferred-marked blocks and funky white space.

This reverts commit 5a3893958a.
Reason for revert: Breaks some chromium tests. Not your fault, but it's blocking the roll so we have to fix those first -- then you can reland without changes: https://ci.chromium.org/p/v8/builders/luci.v8.ci/V8%20Linux%20-%20debug/21727
Original change's description:
> [array] Move Array.p.sort to Torque and use TimSort instead of QuickSort
>
> This CL changes the sorting algorithm used in Array.p.sort from
> QuickSort to TimSort (implemented in Torque).
>
> Detailed performance results can be found here: https://goo.gl/4E733J
>
> To save on code space, fast-paths are implemented as sets of
> function pointers instead of specializing generics.

This CL adds a ToObject_Inline CSA macro that avoids the "ToObject"
builtin call if the passed argument is already a JSReceiver.
The CL also replaces all occurences of ToObject in Torque code with
ToObject_Inline.

This is the V8 equivalent to https://crrev.com/2779193002 and must be landed
before //build/secondary/{gtest,gmock} are removed from Chromium. This started
out as https://crrev.com/2847693002
The changes in tools/ were authored by yangguo@chromium.org and
initially shared in http://crrev.com/2849783003.
GoogleTest (gtest) and GoogleMock (gmock) are now hosted into the same
googletest repository. In order to cope with this, the googletest
repository is now sourced at third_party/googletest.
The file/directory layout of Google Test is not yet considered stable.
To minimize disruption while Google Test stabilizes, Chromium code will
be insulated from third_party/googletest.
* testing/gtest/include/gtest/ and testing/gmock/include/gmock have
been populated with headers that forward into the appropriate
locations of third_party/googletest
* testing/BUILD.gn has been populated with the targets
//testing/gtest(:gtest_main) and //testing/gmock(:gmock_main),
which depend on the appropriate //third_party/googletest targets.
All Chromium code should keep depending on the targets and
headers in testing/{gtest,gmock} for now.

This is needed to insulate generated code from blink::protocol namespace
from naming changes that we plan to do in the Great Blink Rename (which
in particular will rename wtf::StringBuilder::find method into Find).
This CL also includes roll of inspector_protocol which starts to
generate code that uses the new StringUtil::find adapter method:
rolling third_party/inspector to 1a7cbe8ba8fa0d622586f549a97c73d9b52efbea

third_party/inspector_protocol is tracked in git and ignoring it causes
problems if the tree is copied to another git repository (e.g. Node.js)
Similarly, third_party/binutils has some files checked in. This adds a
.gitignore file in this directory (same as Chromium).

When Chromium and V8 use the same version of inspector_protocol, any protocol change takes at least 4 patches and 3 waiting for rolls.
To simplify this process we need to have two diffrent versions of inspector_protocol in Chromium and V8. Current state of inspector_protocol was extracted into separate repository [1]. This CL puts last version of inspector_protocol into third_party/inspector_protocol and removes dependency on inspector_protocol in Webkit.
