[heap] Add a simple implementation of Heap::IsPendingAllocation · 889b27b8

Ulan Degenbaev authored Nov 11, 2020

The new predicate allows a background thread to check if the given
object was recently allocated and may potentially be unsafe to read
from the background thread.

The current implementation has relatively high overhead as it loads
two pointers per heap space. It will be optimized in the future.

[wasm-gc] Known-depth constant-time subtype checks · 8d611a87

Jakob Kummerow authored Nov 11, 2020

Previously, we performed "is A subtype of B?" checks by walking
A's supertypes list and comparing every found type to B.
This CL stores not just A's immediate parent type on A, but its
entire list of supertypes, and uses that list plus compile-time
knowledge of B's distance to the root type in order to compare
only exactly one of A's supertypes to B.

[turboprop] Fix DCHECK in SetOptimizedCode · b90aa33e

Mythri A authored Nov 10, 2020

With --always-opt / %OptimizeFunctionOnNextCall it is also possible
that we see CompileOptimizedConcurrent marker when we install optimized
code. For example,
1. Mark function for concurrent optimization and trigger a job.
2. Create a new JSClosure and with --always-opt we optimize concurrently
and install optimized code. This clears the marker.
3. The installed optimized code is GCed or deopts and we re-mark the
function for concurrent optimization.
4. The optimize job created in step 1 finishes.

Fix v8windbg failure on non-ptr-compr builds · 2388f2c1

Seth Brenith authored Nov 10, 2020

On builds without pointer compression enabled, v8windbg currently fails
to display information about objects in the Locals pane. This is because
some important code to get a type name was hidden behind a
COMPRESS_POINTERS_BOOL check. The existing cctest
test-v8windbg/V8windbg is sufficient to catch this error, but apparently
nobody ever runs that test in the failing configuration (Windows,
symbol_level = 2, v8_enable_pointer_compression = false).

[torque] @relaxedWrite annotation; generate Context C++ class/BodyDescr. · f8809072

Tobias Tebbi authored Nov 11, 2020

This CL lets Torque generate the Context C++ class and BodyDescriptor
for Context.
This requires two Torque changes:

- Allow @generateBodyDescriptor on @abstract classes, since all Context
  classes share the same BodyDescriptor.

- Add a new annotation @relaxedWrite, which makes C++ setters
  use WRITE_RELAXED_FIELD instead of WRITE_FIELD.
  Attention: As a side-effect, this CL disables using
    WRITE_RELAXED_FIELD by default for all non-array fields. If this
    causes problems, we should manually add @relaxedWrite to the
    corresponding fields.

[wasm][cleanup] Avoid data race on has_priority_ field · 424e7a06

Clemens Backes authored Nov 10, 2020

After https://crrev.com/c/2529140, the actual data race should already
be fixed. This CL updates documentation (by moving the field to the
fields protected by {mutex_}), and updates {SetHighPriority} to also
take the mutex. This change is not strictly necessary, because this
method is only called right after creating the object, so no other
threads have access to it yet. But relying on that seems brittle, and
moving the initialization to the constructor is a bigger refactoring
that I don't consider worth it at the moment. The whole priority
management will probably be refactored again soon anyway.

[wasm] Replace the js-to-wasm wrapper eagerly for all matching functions · a7ba1705

Vicky Kontoura authored Nov 10, 2020

This CL aims at avoiding compilation of the same js-to-wasm wrapper
multiple times by iterating over all exported functions in the export
table and replacing the wrapper for all functions that share the same
signature with the function that tiered up.

* Drive-by: rename Factory::NewFunctionForTest to ..ForTesting (this is
  the correct suffix recognized by our tooling to ensure it's only
  called from tests).

[runtime] Remove SourceTextModule::script field · c033eb04

Camillo Bruni authored Nov 10, 2020

By keeping the SharedFunctionInfo around for modules with the kErrored
status, we don't need the additional script field anymore. The script
can thus be always accessed indirectly through the code object.

Removing the script field fixes context serialization of modules.

[wasm-gc] Don't only consider 7 bits of i33 values · f792114b

Manos Koukoutos authored Nov 10, 2020

When comparing a decoded i33 value (v) to an expected value (ex) given
as a 7-bit unsigned byte, we first truncated (v) to 7 bits. This
resulted in values which coincide with (ex) only in the last 7 digits to
erroneously be accepted.
