ab4986b8e1 Revert "[flags] Predictable should not imply single-threaded"
This reverts commit 5fd3858258.

Reason for revert: Failures on the predictable bot: https://ci.chromium.org/ui/p/v8/builders/ci/V8%20Linux%20-%20predictable/36749/overview

Original change's description:

5fd3858258 [flags] Predictable should not imply single-threaded
The --predictable flag is often used to reproduce issues, and having it
imply --single-threaded can change decisions like which compiler(s) to
use. This is because --single-threaded is meant to be set by embedders
(hence we do our best to support single-threaded execution), whereas
--predictable is a testing-only flag which should not change semantics
too much. The fact that --predictable executes everything in a single
thread is already implied by the PredictablePlatform.

c21d0148d6 [testrunner] Implicitly detect trivial flag contraditions
This changes the test runner to automatically treat cases in which
both a flag and its negation are present as a flag contradiction.
Example: "--foo --no-foo".

With this change it's no longer necessary to explicitly specify these
trivial contraditions in variants.py.

Note: since negations are created through simple string operations,
bogus constructions are possible ("--nobodys-perfect" ->
"--bodys-perfect"). We accept these as unlikely-to-cause-problems.

ee56a9863e [test] Run heavy tests sequentially
This adds a new status file indicator "HEAVY" to mark tests with high
resource demands. There will be other tests running in parallel,
but only a limited number of other heavy tests. The limit is
controlled with a new parameter --max-heavy-tests and defaults to 1.

The change also marks a variety of tests as heavy that recently had
flaky timeouts. Heavy also implies slow, hence heavy tests are
executed at the beginning with a higher timeout like other slow tests.

The implementation is encapsulated in the test-processor chain. A
new processor buffers heavy tests in a queue and adds buffered tests
only if other heavy tests have ended their computation.

8807f0ad48 [tools] More Python 3 compatibility fixes
These should all be forward/backward compatible with Python 2/Python 3.

[tools] Tweak statusfile.py for Python 3

.iteritems() does not exist in Python 3, only .items().

(While .iteritems() was meant to be an optimization over .items()
in Python 2, .items() should work fine, and it is forward/backward
compatible.)


[tools] Fix another Python 3 issue in mb.py

sys.platform used to return e.g. 'linux2', which is 'linux' plus
whatever the first digit of `uname -r` was when Python was built.
As of Python 3.3, it always returns just 'linux' for Linux OSes.
Use `sys.platform.startswith('linux')` for forward/backward
compatibility.


[tools] Make base_runner.py Python 3 compatible

dict.keys() returns a dict_keys in Python 3, whereas it
used to return a simple array. list() is forward/backward
compatible with identical results on Python 2/3 (returns array).

(Tested on Linux x64, trying to recreate NodeJS's CI workflow.)


[tools] Make tools/dev/v8gen.py work with Python 3

dict.keys() returns a dict_keys in Python 3, whereas it
used to return a simple array. list() is forward/backward
compatible with identical results on Python 2/3 (returns array).

Comparing a None-type value numerically used to result in the
None-type value always being considered "less than" the thing
it is compared to. As of Python 3, numerically comparing against
None or None-typed values results in an error. Check if a value
is truthy before numerically comparing it, for forward/backward
compatibility.

print() used to transparently decode byte strings in Python 2.
In Python 3, they must be explicitly decoded first.

(Tested on Linux 64-bit, trying to recreate NodeJS's CI workflow.)

4f2f14f8cd [compiler] Remove --turbo-direct-heap-access
On a per-job basis, --turbo-direct-heap-access should be equal to
whether concurrent inlining is enabled. We simplify involved logic by
removing the flag, and replacing all access to

- FLAG_turbo_direct_heap_access, and
- FLAG_concurrent_inlining

inside compiler/ with
OptimizedCompilationInfo::is_concurrent_inlining() (or derived values).

Generic wasm wrappers are enabled by default now (since
https://crrev.com/c/2562241), so we can remove the flag from the
nooptimization variant. Instead, we should have a configuration which
tests --no-wasm-generic-wrapper to find bugs in the compiled wrappers
earlier.

Also add an entry for contradictory flags, and reformat that list to
respect the 80 columns limit.

644b730631 Add test coverage for x86 processors with SSE3 but not SSSE3 support.
One of the x86 ISA extensions is confusingly named SSSE3 (*Supplemental*
Streaming SIMD Extensions 3). SSSE3 supersedes SSE3, and is superseded
by SSE4.

This CL adds testing coverage for x86 CPUs that support SSE3
instructions, but do not support SSSE3 instructions. Chrome supports
these CPUs, and they are used by a non-trivial amount of Chrome's users
on Windows. This CL aims to cover all the spots missed by
https://crrev.com/c/2757893.

3345472f87 [wasm] Remove negative implication from --single-threaded to --liftoff
The negative implication from --single-threaded to --liftoff was
introduced because with --single-threaded, no tier-up to TurboFan is
possible, and TurboFan provides faster code and smaller code

This CL removes this implication. The reason is that this implication
does not only define the default compiler for --single-threaded to
TurboFan, and also completely disables the option to use Liftoff
instead. By removing the implication, and embedder who uses
--single-threaded can decide by themselves if they want to use Liftoff
by setting --liftoff, or if they don't want to use Liftoff by setting
--no-liftoff.

7f15f3e7ad [turboprop] Don't use concurrent inlining for TurboFan compilations
With concurrent inlining, the inlining phase happens on the background
thread and the data needed for the inlining phase is serialized on
the main thread. The serialization phase tries to gather data about
functions called which is sometimes more expensive than inlining phase
itself. So it's better not to use concurrent inlining for TurboFan
compilations when tiering up from Turboprop to TurboFan. Turboprop
compilations don't inline and hence it is OK to continue using
concurrent inlining for Turboprop compilations.

a18a674bb8 [api] Introduce a single-threaded version of DefaultPlatform
The new platform can be used in combination with --single-threaded.
It disables background threads and thus avoids waiting on mutexes
and condition variables completely, which is useful for V8 embedders
that fork the V8 process after initialization.

As a bonus the new platform allows use to test --single-threaded and
has already uncovered an existing bug in parallel pointer updating code.

5326c4f86e [turboprop] Turnoff inlining for Turboprop based on compilation target
Turboprop adds a negative implication for inlining to disable inlining
with turboprop. When we add tiering up support from Turboprop, this
implication means we would no longer inline functions even with
Turbofan. This cl instead turns off inlining for turboprop compilations
so we still don't inline for Turboprop compilations but support
inlining for Turbofan.

5720d2056c [regexp] Add 'l' flag to force experimental engine
This commit adds the 'l' (linear) RegExp flag (as in e.g. /asdf|123/l)
that forces execution in linear time.  These regexps are handled by the
experimental engine.  If the experimental engine cannot handle the
pattern, an exception is thrown on creation of the regexp.

The commit also adds a new global V8 flag and changes an existing one:
* --enable-experimental-engine, which turns on recognition of the RegExp
  'l' flag.  Previously this flag also caused all supported regexps to
  be executed by the experimental engine; this is not the case anymore.
* --default-to-experimental-regexp-engine takes over the previous
  semantics of --enable-experimental-regexp-engine:  We execute all
  supported regexps with the experimental engine.

2000aea58a Reland^4 "[flags] warn about contradictory flags"
This is a reland of 0ba115e6a9
Changes compared to last reland:
- Fix Python code trying to write to expected_outcomes, which is now a
  computed property.
- Fix remaining place in d8.cc that ignored the --fuzzing flag.
- Expect flag contradictions for --cache in code_serializer variant.

faed29869f [nci] Change testing mode to --turbo-nci-as-midtier
To properly test tier-up in the V8 test suite, change the test variant
previously called --turbo-nci-as-highest-tier to
--turbo-nci-as-midtier.  As a midtier (between ignition and turbofan),
all major parts of the NCI pipeline (codegen, caching inside the same
native context, tier-up) are exercised by test suite.

d8f8a7e210 Reland "[flags] warn about contradictory flags"
This is a reland of b8f9166664
Difference to previous CL: Additional functionality to specify
incompatible flags based on GN variables and extra-flags, used
to fix the issues that came up on the waterfall.

This also changes the rules regarding repeated flags: While
explicitly repeated flags are allowed for boolean values as long
as they are identical, repeated flags or explicit flags in the
presence of an active implication are disallowed for non-boolean
flags. The latter simplifies specifying conflict rules in
variants.py. Otherwise a rule like

INCOMPATIBLE_FLAGS_PER_EXTRA_FLAG = {
  "--gc-interval=*": ["--gc-interval=*"],
}

wouldn't work because specifying the same GC interval twice
wouldn't actually count as a conflict. This was an issue with
test/mjsunit/wasm/gc-buffer.js, which specifies
--gc-interval=500 exactly like the extra flag by the stress bot.

Also, this now expands contradictory flags checking to d8 flags
for consistency.

d1fb6b5a7c [infra] Add and enable nci_as_highest_tier variant
With work on NCI proceeding, it makes sense to test multiple
pipeline configurations.

The nci variant (passes --turbo-nci) now spawns dedicated NCI
compilation jobs and inserts generated code into the code cache.

The nci_as_highest_tier variant (passes --turbo-nci-as-highest-tier)
simply replaces TF with NCI code (no extra jobs, no extra caching).
This mode stresses NCI generated code more than the nci variant, in
which NCI code only runs on cache hits.
