It will now return true for 32-bit constants as well. When enabling this, two errors popped up: one in dissassembler where we might have null hosts, and one in remembered set where we should be compressing the address before storing. As a drive-by: make ppc use full objects until their pointer compression implementation is fully done.

Scripts aren't callable functions. Even though internally they were for a while, they aren't anymore. We shouldn't return them to users as if they were. We already remove strict-mode functions from CallSites, so we now do the same for internal functions that are created for scripts.

Clemens Backes authored
Passing an isolate to {RecompileNativeModule} feels wrong, since compilation and the generated code are totally isolate-independent. In fact, the isolate is only used for updating counters. Instead of passing the counters instead, this CL just refactors the code to support a nullptr for the counters everywhere (some code paths already supported that). The few recompilation would not make a significant difference in the histograms anyway, and even have the risk of skewing the data. Drive-by 1: Rename {TierUp} to {StartTierUp} and update comments. Drive-by 2: Remove non-actionable TODO.

We are currently porting Chromium over to use the Perfetto client library for tracing[1]. When this mode is enabled, V8 should also use the Perfetto library built by Chromium instead of building an indepedendent copy. This patch enables that behavior, gated by the |use_perfetto_client_library| flag set by Chromium. We also roll Perfetto to the latest version, add a couple of missing dependencies on v8_tracing and add a missing tracing category group.

This replaces VisitMode with a set of option flags that allow skipping specific roots like unserializable, weak, global handles, etc. The advantage is that it is no longer coupled with the callers and does not know about different types of GCs and their phases. The CL is pure refactoring without behavior changes except for the heap verification where more roots are verified that before.

In the existing code we used a register of the UseScratchRegisterScope for the destination address. However, this register is needed for the ParallelRegisterMove as well. With this CL we use fixed registers for the destination address and the offset as well. The CL also changes the implementation of CalculateActualAddress to allow to set an explicit register for the result.

This patch implements f32x4.pmin, f32x4.pmax, f64x2.pmin, and f64x2.pmax for x64 and interpreter. Pseudo-min and Pseudo-max instructions were proposed in https://github.com/WebAssembly/simd/pull/122. These instructions exactly match std::min and std::max in C++ STL, and thus have different semantics from the existing min and max. The instruction-selector for x64 switches the operands around, because it allows for defining the dst to be same as first (really the second input node), allowing better codegen. For example, b = f32x4.pmin(a, b) directly maps to vminps(b, b, a) or minps(b, a), as long as we can define dst == b, and switching the instruction operands around allows us to do that.

This changes the existing implementation that creates an unresolved reference for those cases to look at exactly what scopes are relevant so it can correctly handle catch scopes and avoid re-resolving later. Variable through with aren't marked as assigning since this information isn't relevant for the with itself; and if the with is passed through, there's no need to mark the outer variable as assigned since it's either initialized or it isn't. The catch variable is assigned since it is relevant for the catch variable. The CL uses LookupLocal which wouldn't work for deserialized scopes, but this isn't relevant because 1) eval scopes are declaration scopes, and 2) eval causes all outer variables to be maybe_assigned anyway.

Remove the SWEEPING state from incremental marking. Sweeping is now always completed when starting incremental marking. Before this change there needed to be a safepoint each for starting marking and completing sweeping. Now both happens within a single safepoint.

Background threads can now start incremental marking when necessary. In contrast to the main thread they always need to schedule a job and can't start incremental marking right away. Background threads also use a simpler heuristic for deciding whether to start incremental marking.

There's no need for them to be in NativeContext. This CL moves the minimal subset of SFIs related to Promises / finally.

This reverts commit 6204768b. Reason for revert: A number of Clusterfuzz reports (e.g. https://bugs.chromium.org/p/chromium/issues/detail?id=1079474) Original change's description: > [turbofan] Improve equality on NumberOrOddball > > This CL cleans up CompareOperationFeedback by replacing it with a > composable set of flags. The interpreter is changed to collect > more specific feedback for abstract equality, especially if oddballs > are involved. > > TurboFan is changed to construct SpeculativeNumberEqual operator > instead of the generic JSEqual in many more cases. This change has > shown a local speedup of a factor of 3-10, because the specific > operator is way faster than calling into the generic builtin, but > it also enables additional optimizations, further improving > runtime performance. > > Bug: v8:5660 > Change-Id: I856752caa707e9a4f742c6e7a9c75552fb431d28 > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2162854 > Reviewed-by: Mythri Alle <mythria@chromium.org> > Reviewed-by: Georg Neis <neis@chromium.org> > Commit-Queue: Nico Hartmann <nicohartmann@chromium.org> > Cr-Commit-Position: refs/heads/master@{#67645} TBR=rmcilroy@chromium.org,neis@chromium.org,mythria@chromium.org,nicohartmann@chromium.org Change-Id: I3410310ed2b1ff2eaee70c1b91c3151d35866108 No-Presubmit: true No-Tree-Checks: true No-Try: true Bug: v8:5660 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2190414Reviewed-by: Nico Hartmann <nicohartmann@chromium.org> Commit-Queue: Nico Hartmann <nicohartmann@chromium.org> Cr-Commit-Position: refs/heads/master@{#67673}
