When enabling tracing with the debugger 'trace' command, enable logging everything instead of just disassembly and general purpose registers. This is not only more useful but also consistent with the --trace-sim flag.

This moves several simple StateValuesAccess methods as well as SparseInputMask::InputIterator::IsReal into their header files so they can be more easily inlined. This gives about a 7% improvement to the BackgroundSelectInstructions runtime call stat. Also marks some methods called by the new methods as V8_PRIVATE_EXPORT so component build test can build.

Define a macro in code-generator-x64 to help identify cases when the shift value is an immediate/constant. In those cases we can directly emit the shifts without any masking, since the instruction selector would have modulo-ed the shift value. We also don't need any temporaries in this case. This is only x64 codegen, optimizations for other archs will come in future patches (and will probably look very similar to this). The current test case passes the shifts as an immediate, so we add a new path that loads the shift value from memory, thereby exercising the slower path of non-immediate shift value.

This relands commit e8832647. The flaky test failures seems to be related to tiering, Liftoff generating different call descriptors from TurboFan when Simd128 is unsupported (since TurboFan will lower the graph, but Liftoff can continue running simd-call.js just fine). We temporarily disable tiering for this test, until we get a proper fix, like https://crrev.com/c/2029427/, but that fix requires this change since more tests will fail without the lowering fixed.

We will use this state in devtools via the inspector to indicate whether a thread is currently stuck polling in atomics.wait. VMState already distinguishes the important states we care about which are idle vs. running JS. We also want to know the state for atomics.wait(), which is commonly used in WebWorkers to poll the main page for work to do. This CL just adds and maintains the state and adds assertions in atomics tests. Another CL will emit inspector notifications when the VMState changes in a way that the inspector cares about. Re-flow comments as a drive-by cleanup.

As discussed offline, the current implementation implement each situation separately. I think we can simplify the code a lot by sharing code between the different paths. This CL does that by 1) implementing the kI64Store case separately, because it does not have all the register contraints that the others have, and 2) moving all logic to ensure that the {src} register is usable before the switch, such that it's shared by all the compare-exchange cases. As a side produce, this also fixes issue 1045225, because for i64 stores which actually only use the lower half of {src}, only that half will be pinned.

This uses the most common bottleneck for intercepting range-error creation in correctness fuzzing. Previous abort conditions didn't cover all cases, e.g. they didn't cover the generic NewError called by wasm-results. This also moves code for error-message suppression to the same location for readability. In a follow up we'll remove the other redundant abort conditions that are scattered through the code.

There was a bug in the function body decoder where type checking of brtable only happened if the brtable instruction is reachable. However, type checking is required in all cases where brtable "not unreachable". The difference between reachable and "not unreachable" is a state called spec-reachable where a clever compiler can already infer that the code will be unreachable (e.g. a memory access is out of bounds just by the offset and therefore unconditionally traps), but the spec can not. If an instruction is only spec-reachable, it still has to be type checked.

MarkingWorklistHolder has two references to the shared marking worklist: 1) as a standalone worklist for general marking, 2) as a context worklist for per-context mode marking. Because of that the shared worklist gets updated twice and breaks the invariants of UpdateMarkingWorklistAfterScavenge.

This patch adds a new BackingStore::Reallocate function that internally uses a new ArrayBuffer::Allocator::Reallocate provided by the embedder. The default implementation of the function simply copies the backing store. The embedder can override the function and provide a more efficient implementation e.g. using realloc.

Remove AstConsString "internalization", and instead make the conversion to heap String be on-demand with an Allocate method. We never actually need the heapified cons string more than once, so there's no need to do the internalization walk or do the next/string union dance in the AstConsString class. This also allows us to specify how we want to allocate the String at the call site. In particular, it allows us to allocate a flat SeqString rather rather than a ConsString. This allows us to avoid allocating ConsStrings which will just be passed to a flatten call, and especially avoid allocating dead ConsStrings in the off-thread old space.
