The generation of unwind info to enable stack walking on Windows/x64 (https://chromium-review.googlesource.com/c/v8/v8/+/1469329) was implemented behind a temporary flag, in order to coordinate these changes with the corresponding changes in Chromium. The required changes to Chromium (https://chromium-review.googlesource.com/c/chromium/src/+/1474703) have also been merged, so we can now remove the flag and enable the generation of stack unwinding info by default on Windows/x64.

Simplify accounting for compilation progress. Instead of complicated logic in {OnUnitsFinished} the compilation progress is initialized in {InitializeCompilationProgress}. We now keep tack of - the required baseline tier, - the required top tier, and - the currently reached tier. With this information {OnUnitsFinished} determines whether baseline and top tier compilation are completed.

With very few exceptions, this verifies all skipped write-barriers in CSA and Torque, showing that the MemoryOptimizer together with some type information on the stored value are enough to avoid unsafe skipped write-barriers. Changes to CSA: SKIP_WRITE_BARRIER and Store*NoWriteBarrier are verified by the MemoryOptimizer by default. Type information about the stored values (TNode<Smi>) is exploited to safely skip write barriers for stored Smi values. In some cases, the code is re-structured to make it easier to consume for the MemoryOptimizer (manual branch and load elimination). Changes to the MemoryOptimizer: Improve the MemoryOptimizer to remove write barriers: - When the store happens to a CSA-generated InnerAllocate, by ignoring Bitcasts and additions. - When the stored value is the HeapConstant of an immortal immovable root. - When the stored value is a SmiConstant (recognized by BitcastToTaggedSigned). - Fast C-calls are treated as non-allocating. - Runtime calls can be white-listed as non-allocating. Remaining missing cases: - C++-style iterator loops with inner pointers. - Inner allocates that are reloaded from a field where they were just stored (for example an elements backing store). Load elimination would fix that. - Safe stored value types that cannot be expressed in CSA (e.g., Smi|Hole). We could handle that in Torque. - Double-aligned allocations, which are not lowered in the MemoryOptimizer but in CSA. Drive-by change: Avoid Smi suffix for StoreFixedArrayElement since this can be handled by overload resolution (in Torque and C++).

The main change is the reduction of the number of declared classes by four by using templatized 'using' declarations instead of subtypes. This also uses 'constexpr' to define constants, uses the defined constants consistently, and adds static asserts.

TypedArray#sort has a fast-path when the user does not provide a comparison function. This fast-path utilizes std::sort which operates directly on the raw data. Per spec, std::sort requires the "less than" operation to be anti-symmetric and transitive. When sorting SharedArrayBuffers (SAB) that are concurrently modified during sorting, the "less than" operator stops being consistent as the underlying data is constantly modified. This breaks some invariants in std::sort resulting in infinite loops or straight out segfaults. This CL fixes this by copying the data before sorting SABs and writing the sorted result back. Note: The added regression test is tailored for ASAN bots as a normal build would need too many iterations to consistently crash.

Use `padreg` instead of x18 to maintain alignment in the CPURegList. Also clean up some comments and tidy up RequiredStackSizeForCallerSaved and PushCallerSaved. Change-Id: I80a780e5649e69a1746c43f37c2d1d875120c7a0 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1581609Reviewed-by:

The order of the typeswitch branches causes repeated Smi-checks. This CL fixes this by putting the Number case first. However, the generated code is still worse due to repeated Map and InstanceType loads. This will be fixed by a future load elimination for Torque/CSA.

Add suport for large object space allocations in Turbofan and use it from CSA when young large objects are enabled. This maintains the Turbofan invariant that the generation is statically predictable. In principle, this enables write barrier elimination for large objects allocated from Torque/CSA. But it doesn't seem to trigger much yet, probably we have to improve the MemoryOptimizer.

This CL changes lint errors to not be printed directly to stderr. Instead, they are collected in a list that gets surfaced via the TorqueCompilerResult. This is done so they can be presented to language server clients. This change also removes the "abort_on_lint_errors" option. API users can now decide for themselves what to do, depending on the presence of lint errors in the returned list.
