We currently have three different compresses that we thought it could be
a good idea to merge into only one. Merging them would make sense since
they all end up with the same code being generated. However, we would be
losing knowing the MachineRepresentation in the cases of CompressSigned
and Pointer.
For example, in machine-graph-verifier everything will have to be
MachineRepresentation::kCompressed

Win64 unwind data can specify a language-specific handler function which is
called as part of the search for an exception handler, as described in
https://docs.microsoft.com/en-us/cpp/build/exception-handling-x64?view=vs-2019.
This is used for example by Crashpad to register its own exception handler for
exceptions in V8-generated code.
There is a problem in the code that may cause a freeze on abort: in file
\deps\v8\src\unwinding-info-win64.cc in function CRASH_HANDLER_FUNCTION_NAME the
line:
return EXCEPTION_CONTINUE_SEARCH;
should be
return ExceptionContinueSearch;
These constants are both used in the context of Win32 exception handlers, but
they have different semantics and unfortunately different values:
EXCEPTION_CONTINUE_SEARCH (=0) should be returned by an exception filter
while a language-specific handler should return an EXCEPTION_DISPOSITION value,
and more precisely ExceptionContinueSearch (=1) in this case.

error: it copies the whole MacroAssembler buffer size, not just the size of the

This has no real bad effects, because a CodeRangeUnwindingRecord is stored at
the beginning of a page reserved at the beginning of an isolate code range, but
it is quite bad and we need to fix it.

On newer compilers the {operator delete} with explicit {size_t}
argument would be instantiated for {CompilationState} and used in the

Hence avoid this operator from being created by explicitly providing an

Add a new abstract class TraceEventListener which is just an interface
for consuming trace events. This separates the V8-specific stuff that
an actual perfetto consumer needs to do e.g. handling the has_more flag
and signalling back to the controller with a semaphore.
This is a change from the previous plan of making the PerfettoConsumer
class sub-classable to implement custom consumption of trace events.
This will be difficult when the consumer is created outside of the
PerfettoTracingController as we can't hook up the
consumer_finished_semaphore_ that belongs to the controller.
Now the PerfettoTracingController is responsible for the Consumer life-
cycle and hides it entirely from callers. We add the
AddTraceEventListener() method to allow callers to register a listener
either for testing or a JSON listener for real tracing.
This lets us write tests that can store all the trace events in memory
without first converting them to JSON, letting us write test more
easily. There's an example test add to test-tracing - more tests using
this style will follow.

The win64-specific unwinding info writer should not be part of the
generic EmbeddedFileWriter class. Let's hide it in the platform-specific
writer.

This replaces all typedefs that define types and not functions by the
equivalent "using" declaration.
This was done mostly automatically using this command:
ag -l '\btypedef\b' src test | xargs -L1 \
perl -i -p0e 's/typedef ([^*;{}]+) (\w+);/using \2 = \1;/sg'
Patchset 2 then adds some manual changes for typedefs for pointer types,
where the regular expression did not match.

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.

This reverts commit 384a51da42.
This hack is both broken (builtins now have individual symbols and no
longer resolve to v8_Default_embedded_blob_) and useless (profview
seems to detect builtins just fine without it).

Currently, all background compile tasks run for 50ms, then they all
publish their results and restart. This results in significant
contention during the publish phase.
This CL introduces an atomic counter on the {CompilationStateImpl} to
distribute the deadline more evenly: Each task executes between 50ms
and 200ms, and tries to pick a deadline 5ms after the previously
assigned deadline, if this lies within these boundaries. This speeds up
publishing significantly and saves several percent compilation time
overall.

The category for wasm trace events is "disabled-by-default-v8.wasm",
generated by {TRACE_DISABLED_BY_DEFAULT("v8.wasm")}.
This CL fixes two events that used the category without the
"disabled-by-default-" prefix, and adds two more trace events to make
code GC more visible in the trace.
