This adds the following internal properties to `WasmInstanceObject` values in DevTools: - `[[Module]]` pointing to the `WasmModuleObject`, allowing the developer to find the module to an instance no matter where in DevTools front-end the instance is inspected. - `[[Functions]]`, `[[Globals]]`, `[[Memories]]`, and `[[Tables]]` are shown (when they aren't empty), allowing developers to inspect the entities within an instance no matter where in DevTools front-end it's inspected. This also updates the _Module_ scope for Wasm frames to show the entity containers (`functions`, `globals`, `memories` and `tables`) in addition to the `instance` and `module` to make it easier accessible (fewer clicks to get there), but also to align it better with the _Add property path to Watch_ and _Copy property path_ features (since exactly the same names are exposed via Debug Evaluate on Wasm frames). ``` > Stack > Locals v Module > module > instance > functions > globals > memories > tables ``` Drive-by-fix: Move GetWasmModuleObjectInternalProperties() logic into debug-wasm-support.cc Screenshot: https://imgur.com/ksEHG2I.png Doc: http://bit.ly/devtools-wasm-entities Fixed: chromium:1165294 Bug: chromium:1071432, chromium:1164241, chromium:1165304 Change-Id: Ia88fb2705287c79988ff2b432e4a33ac34e098f5 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2622912Reviewed-by:

`0x12345678` will be written to memory in the same order on BE machines however, as Wasm is LE enforced, a memory load will force a byte reverse operation on BE machines which changes the value.

Make sure gcmole detects issue in DisallowGarbageCollection scopes. DisallowGarbageCollection is widely used in the codebase to document code that doesn't allocate. However, this has the rather unexpected side-effect that gcmole is not run when such a scope is active. This CL changes the default behavior of gcmole to run even with DisallowGarbageCollection scopes present. This will give us the best results of both worlds, dynamic checks by the fuzzer, and static analysis by gcmole. To allow crazy local raw pointer operations there is a new DisableGCMole scope that explicitly disables gcmole.

Add a pre-loop over transition arrays during compaction, that checks whether compaction is needed at all, and whether any of the entries are still uninitialized values as part of deserialization (and therefore no other targets can be dead).

The frame pointer did not point to the previous frame pointer, which made the stack non-iterable with SafeStackFrameIterator.

This CL fixes a bug in the code generation for I32AtomicCompareExchange in Liftoff on ia32. The problem is the inconsistency that LiftoffAssembler::PeekToRegister(...) introduces to the cache state. PeekToRegister loads the value from the value stack into a register, but does not pop the value off the stack. When the value was already stored in a register, the use counter of that register gets decreased, even though the value is still on the stack. The problem arises when this register later gets reused, which is necessary unfortunately on ia32. When SpillRegister is called for this register, all stack values that are stored in this register get written to memory. SpillRegister uses the use counter of the register to detect when the register was spilled to all stack slots that were cached by this register. However, as described above, the value stack and the use counter are inconsistent at that moment, so SpillRegister finishes early and does not spill the register to all stack values, and this causes the bug later. With this CL the decrement of the use counter gets delayed until when the value actually gets popped off the stack.

In memory64, the index is a 64-bit value even on 32 bit. Thus the bounds check needs to check explicitly that the high word is zero.

This adds a first execution test for memory64 in the form of a cctest. Several things are still not working correctly, hence this test only checks TurboFan on 64-bit systems, and Liftoff. Bounds checks in Liftoff are fixed to work correctly on 32-bit. Follow-up CLs will extend the test to also test TurboFan on 32-bit, the interpreter, and traps. All of those features still have issues.
