Double initialization may cause the ExternalPointerTable compaction algorithm to behave non-optimally: Consider the case of an Entry E1 that is owned by a HeapObject O and is marked for evacuation during GC marking. In that case, a new entry E2 is allocated for it, and during sweeping, E1 will be evacuated into E2 and the Handle in O updated to point to E2. However, if a new entry E3 for O is allocated before sweeping, then during sweeping E3 (instead of E1) will be moved into E2. This may then violate the invariant that the compaction algorithms always evacuates an entry out of the evacuation area. This CL therefore forbids double initializaiton of external pointer slots and adds DCHECKs to attempt to catch these in debug builds.

--stress-opt never did what we wanted it to; it ran its runs in different contexts (therefore not able to share feedback across runs), and even if it didn't, each run would create new closures for any defined closures, so we'd still more than likely end up poly- or mega-morphic. Fuzzers cover this use case better than --stress-opt ever did, so now it's just using precious bot time. We can get rid of it.

When we spill a register that we know contains only 32 interesting bits and then reload it from the spill slot, it's enough to reload its lower half. This may save a few bytes, and guards against accidental changes to the upper half (e.g. via pointer decompression).

On arm, SIMD registers alias with pairs of double registers. When deciding where to allocate the parameter values, we expect to see all register-passed parameters before all stack-passed parameters; but due to s128 and f64 params being arbitrarily interleaved this doesn't always hold. This patch fixes that by first finding all registers used for parameters, and then blocking these when allocating registers for other parameters.

Since the function entry stack check happens outside of the IR, the standard register spilling mechanisms don't kick in and registers that expect to be valid might be clobbered. The only such case is, in fact, the new.target register, so make sure it is preserved across the stack check.

This reverts commit aa541f1c. Reason for revert: Reverting due to large regressions for motionmark on M1. Original change's description: > [turbofan][arm64] Emit Lsl for Int32MulWithOverflow when possible > > Int32MulWithOverflow on arm64 uses a cmp to set flags rather than > the multiply instruction itself, thus we can use a left shift when > the multiplication is by a power of two. > > This provides 0.15% for Speedometer2 on a Neoverse-N1 machine, > with React being improved by 0.45%. > > Change-Id: Ic8db42ecc7cb14cf1ac7bbbeab0e9d8359104351 > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3829472 > Commit-Queue: George Wort <george.wort@arm.com> > Reviewed-by: Nico Hartmann <nicohartmann@chromium.org> > Cr-Commit-Position: refs/heads/main@{#82499} Change-Id: I896530a53fbdf6d397922124abddda4140144448 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3854222Reviewed-by:

This CL adds a soft limit (via AllocationObserver) to run incremental marking for MinorMC. Once the soft limit is triggered, roots are marked. This a stepping stone for concurrent marking (YoungGenerationConcurrentMarkingVisitor, go/YGCMV) integration.
