UnsafePointerAdd is unnecessary as long as a proper bitcast is used before the addition. The bitcast is already in the effect chain and prevents the addition from floating before a GC operation.

Since we now promote all young objects into old space on full GCs, we don't need to sweep pages for iterability anymore in new space. Minor MC doesn't need to make a page iterable when promoting the full page into the new space. This is because maps are not reclaimed during a minor GC.

Doc: https://bit.ly/revive-restart-frame This CL implements support for the Debugger's "restart frame" functionality in the unwinder. When the debugger wants to restart a frame, we throw a termination exception. The unwinder checks if we are currently in "restart frame mode", and if so, drops execution into a special builtin instead of trying to find a catch handler. Optimized frames are handled similarly, but the deoptimizer has to materialize the frames first before also dropping into the special builtin. Drive-by: Rename `ShouldRestartFrame` to `IsRestartFrameScheduled`, so we can reuse the name `ShouldRestartFrame` as a query method to check if a specific frame is the frame we want to restart.

Avoid zapping freed memory in NotifyObjectSizeChange. This fixes the linked performance regression introduced with https://crrrev.com/c/3607992. Beginning with that CL we would always zap freed memory on the main thread, while previously we only did this in CreateFillerForArray when the FixedArray could actually contain references. While we could restore the previous behaviour as well, we simply stop zapping freed memory in NotifyObjectSizeChange altogether for better throughput. The reason for zapping was to reduce floating garbage. However this is only relevant for incremental marking which is only enabled for about <1% of the overall runtime.

Multiple code spaces are cheaper on 32-bit systems, because we can directly call between them. Over-reservation on the other hand increases the chance for OOMs. Hence reduce the code space estimation (used for the initial reservation) on 32-bit systems. Numbers were obtained from an older Epic module, Photoshop, and AutoCAD. I'll keep an eye on the {V8.WasmModuleNumberOfCodeSpaces} counter.

... Profiler::Remove. In Profiler::Insert and Profiler::Remove, TSAN cannot figure out that when head_ and tail_ equals, Profiler::Insert will always execute before Profiler::Remove, and tsan will report data race between buffer_[head] write and buffer_[base::Relaxed_Load(&tail_)]. This CL changes the tail_ atomic load and store memory order to gurantee that buffer_ read and write always after and before tail_ load and store, which gives tsan more constraint.

New trace events: - finished OSR compilation. - entry into OSR code. Since the latter now happens without a trip into runtime, tracing is a bit more involved - we need to check FLAG_trace_osr in generated code, and call a runtime function if it is set. Drive-by: Slightly reorganize other OSR tracing.

Builtins are not snapshotted, but instead we insert "builtin wrappers" into the snapshot, and create references to the corresponding builtin when deserializing. Subclassing builtins will be implemented in a follow-up CL.

There are currently several flags to tune V8's optimisation level: --sparkplug, --maglev, --opt This CL tries to make this simpler by introducing yet another flag. --max-opt limits the maximum optimisation tier and avoids the common error to mistake --no-opt with no dynamic optimisations. Settings: --max-opt=999 Allow all optimisations, default configuration. Any number > 3 will do, as long as no other tier will be added. --max-opt=0 Allow only ignition --max-opt=1 Allow up to sparkplug --max-opt=2 Allow up to maglev --max-opt=3 Allow up to turbofan Bug: v8:12825 Change-Id: Iff9a0fcccdf05e9770168053a1430303613a7299 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3605816 Commit-Queue: Camillo Bruni <cbruni@chromium.org> Reviewed-by:Jakob Linke <jgruber@chromium.org> Reviewed-by:
