This makes flako usable on Windows using standard test names. A workaround to bisecting to failures before this CL is to replace the test_name by something like "mjsunit/regress\regress-1138075", i.e. using this on the command line to trigger flako: -p 'test_name="mjsunit/regress\\regress-1138075"' R=liviurau@chromium.org Bug: v8:9218 Change-Id: I37596efcaeca780eeacb27c2841fe8302ddb1e49 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3081610 Commit-Queue: Clemens Backes <clemensb@chromium.org> Reviewed-by:

MapRef::AsElementsKind can now concurrently walk transitions to find a map of the requested elements kind. Note this implementation is still less powerful than what we had before crrev.com/c/3021175, since we never allocate new maps. When the transition walk fails to find an appropriate map, we bail out. I don't expect this to be a problem - when optimizing, the code has already run multiple times and transitioned maps should exist.

Jakob Kummerow authored
This patch significantly speeds up parsing of small BigInts. Its primary idea is to move the loop that's iterating over the string into the FromStringAccumulator API. That enables using function- local variables instead of member fields. A second optimization is to use a stack-allocated digit_t[] array for small sizes, before falling back to a (comparatively slow) std::vector. As a particularly fast path, when this stack-allocated storage is guaranteed to be enough, we can perform inlined multiply-and-add steps directly on that data. Finally, this patch changes the conversion of characters to their numeric values from computations to a lookup table, which is a bit faster for radixes <= 10 (where, in the old code, only one range needed to be checked), and a lot faster for radixes > 10.

Use logical shifts to emulate arithmetic shift, by first adding a bias to make all signed values unsigned, then subtracting the shifted bias. Details are in code comments for SharedTurboAssembler::I64x2ShrS. Also refactor ia32 (which was already using this algorithm) to use the shared macro-assembler function. And convert Liftoff's implementation as well.

The behavior here depends on the platform and may also differ between fast and slow paths [0]. Crash to let the fuzzer know there's nothing interesting here. [0] The reason for the fast-slow-path difference is that sometimes we may trigger different compile jobs on these paths. One example is `split`, which creates a new regexp instance on the slow path, but reuses an existing instance on the fast path.

Upon starting a new full garbage collection the global epoch is incremented. Since EmbedderHeapTracer::TraceEpilogue is called within the marking phase, it is too late to finalize sweeping there as it would use the previous cppgc epoch. This makes metric computation crash as a single V8 full GC epoch contains two different cppgc epochs (finalizing sweeping, new GC cycle). This CL avoids introducing a new EmbedderHeapTracer API and instead makes use of the fact that cppgc is known to V8's heap.

Some tests want to invalidate part of the VM state after an optimization has consumed the old state but before the code is installed. The existing mechanism for this is --block-concurrent-recompilation and %UnblockConcurrentRecompilation(). The former suspends optimization right after PrepareJob, before the background ExecuteJob phase. The intrinsic can then be used to unblock it again. This was good enough so far because the main "consume" work used to happen on the main thread. With concurrent inlining this is no longer true and we need something else. This CL introduces three intrinsics: %DisableOptimizationFinalization turns off automatic finalization of background optimizations. %FinalizeOptimization() can then be called at an appropriate time to manually finalize (and thus install) the code and reenable automatic finalization. In case one wants to perform some action on the main thread after the concurrent optimization has finished but before it is finalized, one can do so with the help of %WaitForBackgroundOptimization() (see tests). In a followup CL I'm removing the old mechanism since it now seems redundant.

This reverts commit 1c0cca0f. Reason for revert: this made tree closed. (https://crbug.com/1238174) Original change's description: > Reland: [wasm] Check correctness of thread-local write protection > > The fix landed as a separate CL: https://crrev.com/c/3081522 > This is an unmodified reland. > > Original description: > We make an undocumented assumption in {CodeSpaceWriteScope} that a > single thread will only work on one module at a time. If this is > violated, the thread-local {code_space_write_nesting_level_} would > prevent the second module from being switched to writable. > > This CL adds a second thread local (in debug only) to check that if > there is already a {CodeSpaceWriteScope} open that it contains the same > {NativeModule} as any nested scope. > > R=jkummerow@chromium.org > > Bug: v8:11974 > Cq-Include-Trybots: luci.v8.try:v8_linux_gc_stress_dbg_ng > Cq-Include-Trybots: luci.v8.try:v8_mac64_gc_stress_dbg_ng > Change-Id: Id827b6ca472f695e4500584349aba159aa07eed1 > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3080578 > Commit-Queue: Clemens Backes <clemensb@chromium.org> > Reviewed-by: Jakob Kummerow <jkummerow@chromium.org> > Cr-Commit-Position: refs/heads/master@{#76177} Bug: v8:11974, 1238174 Change-Id: I74d8723344e4b9015d956ebfe3fda492280356b6 Cq-Include-Trybots: luci.v8.try:v8_linux_gc_stress_dbg_ng Cq-Include-Trybots: luci.v8.try:v8_mac64_gc_stress_dbg_ng No-Presubmit: true No-Tree-Checks: true No-Try: true Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3084041 Auto-Submit: Minoru Chikamune <chikamune@google.com> Commit-Queue: Rubber Stamper <rubber-stamper@appspot.gserviceaccount.com> Bot-Commit: Rubber Stamper <rubber-stamper@appspot.gserviceaccount.com> Cr-Commit-Position: refs/heads/master@{#76184}
