This API allows allocating shared memory mappings inside a virtual address space from a platform-specific handle to a shared memory object. This will make it possible to allocate shared memory inside the sandbox, for example as backing memory for ArrayBuffers.

These should not be allowed inside the sandbox as they could be corrupted by an attacker, thus posing a security risk. Furthermore, executable pages require MAP_JIT on macOS, which causes fork() to become excessively slow, in turn causing tests to time out. Due to this, the sandbox now requires the external code space. In addition, this CL adds a max_page_permissions member to the VirtualAddressSpace API to make it possible to verify the maximum permissions of a subspace.

Even though this is not a perfect protection, it will make it harder to write to the wasm code space because it's not permanently RWX.

This was mostly unused. We should simply be able to use CodeKind plus related predicates instead. Replace FeedbackVector::optimization_tier with maybe_has_optimized_code, which states whether the optimized code cache is filled. The value is updated lazily and may lag behind the actual code cache state. We only use this field for quick cache-empty? checks from generated code.

Instead of using runtime lookups of various bytecode properties (like whether they read/write the accumulator, what their operands do to registers, etc), do a switch over the bytecode itself once and dispatch to update methods that are templated on the bytecode and statically know everything about it.

.. to resolve the overloaded 'runtime' term and overall pick a more meaningful name for this class. It's neither very related to runtime (instead it's called periodically when the bytecode interrupt budget is exhausted); nor is profiling its main purpose. This class is responsible for controlling tiering decisions, hence the new name 'TieringManager'.

This CL replaces evacuation in MinorMC with always promoting pages. Pages in new space are promoted first within new space and then to old space upon a second GC. This implementation should not yet be used in production and is guarded behind a runtime flag. In case all pages in new space have at least one live object on them, all pages will be promoted and new space will still be out of memory, thus immediately triggering a second young gen GC that will promote all objects to old space. Further CLs will mitigate this issue. Bug: v8:12612 Change-Id: I329ea01d6d15c0942db2eeeea87c5cefcac75502 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3448385Reviewed-by:
