The FrameSummary::FunctionName() method is only used by the FrameInspector in the debugger, so the natural place to put the dependency on GetWasmFunctionDebugName() is in there, rather than adding a new dependency to frames.cc.

Disable the checksum comparison for the read-only snapshot when --stress-snapshot is used, since it's possible that it would be corrupted. This corruption is not important as the purpose of stress-snapshot is not to produce a useable snapshot, but to test that the serialization/deserialization does not fail for any given objects. Since the --stress-snapshot flag's value is now used outside of d8, this also moves it to flag-definitions.h.

This is a partial reland of https://crrev.com/c/2850932, which was reverted because the histogram failed Chromium integration. The V8 histogram added here uses only two values (0 = no support, 1 = support), but is declared with 3 buckets in order not not fail a DCHECK on Chromium's side. As soon as https://crrev.com/c/2874651 lands in Chromium, we can properly declare the histogram here with only 2 buckets, but for now this is good enough to get early data on PKU support in the wild. The other part of the original reverted CL (adding PKU alloc and free functions, and a V8 flag for PKU) was already landed again in https://crrev.com/c/2878738 Original change's description: > [wasm] Add PKU alloc/free and support counter > > To enforce W^X for the WebAssembly code space, we want to explore using > Intel memory protection keys for userspace, also known as MPK, PKEYs, or > PKU.

Jakob Gruber authored
The logic in JSHeapBroker::TryGetOrCreateData assumes that parts of the object are safe to read. In particular, the instance type must be readable for the chain of `Is##Name()` type checks. This is guaranteed if - a global memory fence happened after object initialization and prior to the read by the compiler; or - the object was published through a release store and read through an acquire read. The former is protected by the new call to ObjectMayBeUninitialized (which internally calls IsPendingAllocation) in TryGetOrCreateData. The latter must be marked explicitly by calling the new MakeRefAssumeMemoryFence variant. Note that support in this CL is expected to be incomplete and will have to be extended in the future as more cases show up in which MakeRef calls must be converted to MakeRefAssumeMemoryFence or to TryMakeRef.

This change turns the previously used XOR-based type checks for external pointers into AND-based type checks. With those, the type tag is ORed into the top bits of an external pointer when it is written, and the type check performed on every load is done by ANDing the value with the inverted tag. This will later allow type checking and masking off the GC marking bits of external pointers in a single operation.

Torque-generated relaxed/acquire/release accessors now expect an additional Tag argument to be more consistent with handwritten accessors. Torque's annotations are renamed from @relaxedRead, @relaxedWrite, @acquireRead and @releaseWrite to @cppRelaxedLoad, @cppRelaxedStore, @cppAcquireLoad and @cppReleaseStore, repesectively. This renaming shall better reflect the fact that those annotations just generate corresponding synchronization on the generated C++ accessors (not CSA code) and be more consistent with the C++ side of things where "Load" and "Store" is used instead of "Read" and "Write". This CL uses these new annotations on a few fields in DebugInfo and FunctionTemplateInfo to have Torque generate accessors automatically.

Resetting the flag in the scope desctructor causes concurrent access to the flag value, triggering a TSAN failure when --stress-concurrent-inlining is on.

The line being modified currently causes a 32-bit build with MSVC to give out this warning: C2397: conversion from 'int32_t' to 'v8::internal::byte' requires a narrowing conversion. Avoid the warning by declaring `shift` as type byte to start with.

The ScheduleEarly phase of the scheduler initializes the minimum_block values which are only required for loop hoisting. If there are no loops, running this step is unecessary overhead.
