This CL disables EnqueueMicrotask and RunMicrotasks on detached contexts. That is, if an embedder call DetachGlobal() on a v8::Context, EnqueueMicrotask on that context will not take effect, and all Microtask that is enqueued before DetachGlobal will be cancelled. On Blink, this implies that a frame will no longer run a microtask after it's navigated away. OTOH, detached frames in Blink are not affected.

This unifies how continuations after a control transfer are handled within the interpreter loop. To avoid bumping the {pc} we can either reset the opcode length to zero or just "continue" the loop.

The new scheduling reduces the main thread marking performed in tasks and on allocation. It is based on two counters: - bytes_marked, - scheduled_bytes_to_mark. The bytes_marked accounts marking done both the main thread and the concurrent threads. The scheduled_bytes_to_mark increases based on allocated bytes and also based on time passed since the start of marking. The main thread steps are allowed to mark the minimal amount if bytes_marked is greater than scheduled_bytes_to_mark. This also changes tasks posted for marking. Before only normal tasks were posted. Now delayed tasks are posted if the marker is ahead of schedule.

For the initial implementation we simply keep the capacity of the young large object space in sync with the capacity of the new space. The only subtlety is that we allow at least one large object independent from its size. So it may exceed the capacity of the space. This also fixes setting of the large page flags for incremental marking.

This adds constant field tracking for arrays. To prevent changing the field in some other elements-kind-branch of transition tree, we only use the const information in the optimizing compiler if the map is not an array map or if the map is stable (since stable maps cannot transition to a different elements-kind-branch without deopt).

V8 test suites return tests by loading them into memory up-front. Up-front loading has memory and loading-time overhead for the testrunner. This CL converts the test-suites to load tests during the test run in parallel. After CL, most test suites start running immediately and all test suites start running after 3 seconds on a modern SSD. This CL eliminates the 200 MiB memory spikes that causes memory problems in mac minis. Overhead of running test262 before CL: Line # Mem usage Increment Line Contents ================================================= 264 225.760 MiB 195.8.000 MiB tests = self._load_testsuite_generators(args, options) ------------------------------------------------- Overhead of running test262 after CL: Line # Mem usage Increment Line Contents ================================================ 264 28.840 MiB 0.000 MiB tests = self._load_testsuite_generators(args, options) ------------------------------------------------- R=machenbach@chromium.org CC=yangguo@chromium.org,sergiyb@chromium.org Bug: v8:8174, v8:8552, v8:8728 Change-Id: Iab540b9410239b05dc80b4a5228db25d8b8fb3b9 Reviewed-on: https://chromium-review.googlesource.com/c/1454478 Commit-Queue: Tamer Tas <tmrts@chromium.org> Reviewed-by:
