This is a reland of commit a165e82e The reason of revert is SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior ../../src/objects/js-temporal-objects.cc:3837:22 which is the line "nanoseconds_mv = std::round((seconds_mv - std::floor(seconds_mv)) * 1e9);" where seconds_mv is a double and nanoseconds_mv is a int32_t In this reland, we change the type of nanoseconds_mv to double to avoid the ubsan error. Original change's description: > [Temporal] Use double/int32_t instead of int64_t for duration parsing > > Use double and int32_t instead of int64_t in duration parsing result > so we can parse very large duration fields as infinity and throw RangeError in later stages. The three fractional parts can hold up value from 0 to 999,999,999 so we use int32_t to hold it. Other part could be infinity so we use double to hold it. Also rearrange the order of the three int32_t in the struct ParsedISO8601Duration after all the double > > Bug: v8:11544 > Change-Id: I7e5b02f7c7bbb60997f1419f016aed61dd3e0d6c > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3840761 > Reviewed-by: Shu-yu Guo <syg@chromium.org> > Commit-Queue: Frank Tang <ftang@chromium.org> > Cr-Commit-Position: refs/heads/main@{#82754} Bug: v8:11544 Change-Id: If8b72cb4912d8b4fc4c286fc856ea59df5cf0bb7 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3858576Reviewed-by:

Inlining of bar into foo required taking allocation in foo into account as well (crrev.com/c/1021734), but this makes the test vulnerable to gc timing changes since other allocations are also inlined into foo and may die at arbitrary times (as observed when enabling MinorMC). Fix by preventing inlining of bar into foo. Bug: v8:12612 Change-Id: I2d8848d4002334d329c4b2cc8f18bff1296f5cc1 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3882970Reviewed-by:

Currently this observer uses 80% of initial new space capacity as step size. But this means that after the first minor GC this will most likely decouple from the current new space size since the allocation counter isn't reset after a GC and surviving objects aren't accounted. Use 64K as step-size since this should be large enough to not cause regression but it should still work for Scavenger and Minor MC such that a step invocation will be performed close to reaching 80% of new space capacity.

We used to remove the page from the space in the "evacuation" phase, such that the following "update pointers" phase wouldn't try to update pointers for evacuation candidates. In this CL we move page removal to ReleaseEvacuationCandidates() which is run after the "update pointers" phase finished. In the "update pointers" we can skip evacuation candidates to not update pointers on those pages. That way PostProcessEvacuationCandidates() can be renamed to PostProcessAbortedEvacuationCandidates() since it now only handles aborted evacuation candidates.

BytecodeArray::Disassemble fails a SLOW_DCHECK when invoking from a background thread, due to the little hack to recover the handle inside the function. This CL changes the method to static with a handle as input. The old method calls the static one, since it is allowed to be called by the main thread.

Fix broken DCHECK: When using MinorMC, new space is a paged space and only uses the TO_PAGE page flag. New large object space however still uses both TO_PAGE and FROM_PAGE page flags. With MinorMC it still possible to find reference to FROM_PAGEs, but those pages have to be large pages. Fix broken test: MinorMC may only free empty pages when shrinking. Therefore, shrink may actually not change the space capacity at all (e.g. when all pages have live objects on them). More specifically, the capacity is not guaranteed to be half the previous capacity.
