29879461ce Stop manual unescaping of script source data when preprocessing logs.
It appears that the fields are already being unescaped elsewhere,
perhaps by the JSON writer. So if we unescape when adding the source
filename and contents, unescaping will happen again later and plain
backslashes will be interpreted as escape codes.

365e241780 [interpreter][runtime] Avoid AllocationSites for Array literals in oneshot code
No need to create allocation site for array literals in oneshot code since
they are executed only once. The interpreter emits a runtime call to
CreateArrayLiteralWithoutAllocationSite for creating literals in
oneshot code instead.

cb65864d29 profview: Fix leaking state when switching log files.
When switching log files, if a function was selected the timeline would
attempt to draw its ticks and would usually crash. It would also
preserve the selected section of the timeline.

This patch wipes out the current state when loading a new log file,
with the exception of the current mode (Summary, Bottom up, etc). As a
consequence, the timeline size is now calculated in TimelineView.render
so it will always be drawn at the right size.

V8_Dcheck, but also ensure that the frame is moved up to the DCHECK
frame even if it calls V8_Fatal.

6fcf0a0e3d profview: Improve behavior when given a log with few ticks.
Previously, when given a log with few ticks, the timeline would lump
them all into one or two buckets. This patch allows ticks to be assigned
to buckets more sparsely.

This patch also fixes a bug where there was a gap on the right side of
the timeline, which also caused the function tick marks to be slightly
misaligned. This was more noticable with fewer buckets.

4c0943424c [test] Add logic to run tests on Android
This adds a new command abstraction for running commands on Android
using dockered devices on swarming.

The new abstraction handles pushing all required files to the device.
The logic used for pushing and running is reused from the perf runner.

This adds only the mjsunit test suite. Others will be handled in
follow up CLs. The suite logic is enhanced with auto-detection of files
to be pushed to devices, for e.g. load or import statements.

Some test cases need an extra resource section for specifying required
files.

Remaining failing tests are marked in the status files for later
triage.

f642de00bf Escape backslashes when logging.
Log::MessageBuilder was already escaping most unsafe characters when
they were being logged, but plain backslashes were not. Merely updating
the existing escaping path was not sufficient, as recursion would cause
escape codes to be doubly escaped. This patches refactors the API to
ensure incoming text is escaped exactly once.

363fe1eb66 [Intl] Optimize Intl.Collator
This patch ports most of the Intl.Collator from JS to C++.

The Intl.Collator object no longer stores all the resolved
values. Instead these are looked up on demand as part of
Intl.Collator.prototype.resolvedOptions(), saving several words. In
the future, we can cache the result of the resolvedOptions as well.

In this patch, we use ICU to do parsing of the unicode extension in
the bcp47 language tag instead of using a custom extension parser.

This patch also fixes several spec compliance bugs as well.

cdb4d913f6 [Intl] Optimize Intl.PluralRules
Previously, Intl.PluralRules was mostly implemented in JavaScript. This
patch moves most of the constructor and parts of other methods to C++.

The size of the Intl.PluralRules object is reduced by not storing
MinimumIntegerDigits, MinimumFractionDigits, MaximumFractionDigits,
MinimumSignificantDigits, MaximumSignificantDigits. Instead these are
looked up from icu::DecimalFormat as required.

Another optimziation is that we don't create the result of
resolvedOptions when the Intl.PluralRules object is constructed, but
instead defer until this method is called. In the future, we may want
to cache the result.

This patch also cleans up several error handling paths that shouldn't
happen with ICU and instead just crashes should it ever happen.

c2ee9c6af7 [iwyu] Avoid overwriting source file with same content
The generate-header-include-checks.py script generates the cc files to
check that headers can be included in isolation. It currently always
writes to all the cc files. This means that after "gclient runhooks",
all these files have to be recompiled.
This CL fixes this by not touching the file if it already contains the
expected content. This avoids hundreds of recompilations after running
the hook.

8dc41a581c [tools] Refactor run_perf.py to use logging module for all status messages
All status messages will be printed into STDERR and only the results will
continue to be written to STDOUT as documentation suggests. Additionally the
following changes are made:
 - on Buildbot each log entry will have a timestamp to make it easy to measure
   time between status messages printed by test runner, users will continue to
   see just the message itself
 - when devil (or any other module) logs error, they will not be interleaved
   with our own output since logging module is thread-safe
 - critical logs replaced with warning since they do not immediately stop
   the test runner
 - logging.exception is used for all exceptions to get formatted stack trace

27cd5d0384 [iwyu] Make string-builder.h an inline file
As discussed offline, this header is not really useful without its
inline definitions. So instead of trying to split it (unnaturally),
declare defeat and make it an inline header file.

Also remove two unnecessary uses of it, move the JSON stringifier
class into its .cc file (because it needs IncrementalStringBuilder
inline) and forward declare in prettyprinter.h.

f15cb8fe54 [tests] Make processing of test filters faster
The test driver compares command-line arguments against test names
it finds on disk. Using Python's "fnmatch" for this nicely handles
wildcards, but is relatively slow. For given test names that don't
contain any '*', we can use string equality testing, which is much
faster.

Example: the time to evaluate

 tools/run-tests.py --arch x64 --mode release \
   $(grep 'object-spread' -l -r test/test262/data/test/ | \
       sed -E 's|\.js$||' | \
       sed -E 's|^test/test262/data/test/|test262/|')

goes from "I gave up and killed the process after several minutes"
to a couple of seconds with this patch.

> In wasm, where we cannot just call a runtime function because code must
> be isolate independent, we always used the trap-on-abort behaviour.
> This causes problems for our fuzzers, which do not catch SIGTRAP, and
> hence do not detect debug code failures.
> 
> This CL introduces a third mode ("hard abort"), which calls a C
> function via {ExternalReference}. The C function still outputs the
> abort reason, but does not print the stack trace. It then aborts via
> "OS::Abort", just like the runtime function.

a462a7854a [turboassembler] Introduce hard-abort mode
For checks and assertions (mostly for debug code, like stack alignment
or zero extension), we had two modes: Emit a call to the {Abort}
runtime function (the default), and emit a debug break (used for
testing, enabled via --trap-on-abort).
In wasm, where we cannot just call a runtime function because code must
be isolate independent, we always used the trap-on-abort behaviour.
This causes problems for our fuzzers, which do not catch SIGTRAP, and
hence do not detect debug code failures.

This CL introduces a third mode ("hard abort"), which calls a C
function via {ExternalReference}. The C function still outputs the
abort reason, but does not print the stack trace. It then aborts via
"OS::Abort", just like the runtime function.
This will allow fuzzers to detect the crash and even find a nice error
message.

Even though this looks like a lot of code churn, it is actually not.
Most added lines are new tests, and other changes are minimal.

4b4125778a [iwyu] Add script to check that headers can be included in isolation
The most important point of IWYU (include-what-you-use) is that each
header includes everything it is using, so that whoever includes that
header does not need to additionally include other things.
This CL adds a script which generates files to automatically check this.
It is automatically invoked during "gclient runhooks" if the
"check_v8_header_includes" variable is set. This script generates a
number of .cc files in the "check-header-includes" directory, together
with a "sources.gni" file which lists all the generated cc files. Each
file includes one header.
If additionally the gn args "v8_check_header_includes" is set, this gni
file is included, and all the generated CC files will be compiled. This
will detect violations of the aforementioned IWYU rule.

605f94b700 [foozzie] Update existing configs for liftoff
Instead of having a separate liftoff config, which is tested against
the default (which currently means tier-up from liftoff to turbofan),
just choose reasonable liftoff configs for the existing configs.
'ignition' now implies pure liftoff execution.
'ignition_turbo_opt' always compiles with turbofan.
Other configs use the default (tier up).
