- Add v8_code_comments to allow runtime-enabled code comments with --code-comments - v8_code_comments is enable by default in debug mode - Make MacroAssembler::RecordComment helper inlineable to remove call and check overheads when v8_code_comments = false - Make FLAG_code_comments readonly if v8_code_comments = false and benefit from dead-code elimination This saves roughly 5% CompileBaselineVisit time in sparkplug on a 5MiB JS file.

This saves quite some code space on wasm functions, which often do not spill any tagged values (hence the safepoints will just be empty). It also often saves a few bytes on code that actually spills tagged values, but not to the highest frame slots.

Port ede5e814 Original Commit Message: This reverts commit d16eefe0. It is not correct to check for node equality during the graph construction phase, because we can have optimizations that will combine same nodes. So it can happen that in wasm-compiler, the inputs to shuffle are not the same, so we canonicalize using that knowledge that it will not be the same, and allow indices > 15. But later we can have optimizations that combine the 2 inputs (e.g. splat of the same constants), and the instruction selector will see that the input nodes are the same.

The --wasm-write-protect-code-memory flag previously enforced W^X, that is the WebAssembly code space was either writable or executable, but never both at the same time. With compilation in background threads concurrent to execution in the main thread, this simple scheme is no longer viable because the same memory page can indeed be written to and executed at the same time. Hence, this flag is currently broken and disabled and the code space is always writable AND executable. As a first step towards more security, we at least want to write-protect the code space (when not required writable by compilation threads) but at the same time keep it always executable (because of concurrent execution in the main thread). That is, we no longer switch between RX and RW (W^X), but rather between RX and RWX (write-protection only). This CL starts to change from W^X (which was broken) to write-protection only when enabling --wasm-write-protect-code-memory. This is the first of two CLs, where the followup CL will fix the feature, and this CL merely prepares and cleans up the code. In particular, this CL changes the permissions from RW to RWX (due to concurrent execution) and renames `WasmCodeAllocator::SetExecutable()` to `WasmCodeAllocator::SetWritable()` (and similarly named callers) to be consistent with that change. Since the code space is now always executable, this CL also removes now unneeded calls to `SetExecutable(true)` in tests.

We plan to trim the size of safepoint entries, to avoid emitting completely empty entries, and also saving some bytes by removing trailing zeros. This CL prepares that by removing the assumption that the safepoint entry contains one bit per stack slot. Instead, we just use all bits that are there in the safepoint entry when iterating compiled frames.

This changes the interaction between {NativeModule} and {WasmCodeAllocator}. The {WasmCodeAllocator} is a field of {NativeModule}, and only called directly by the {NativeModule}. So far, there were two mutexes involved, the {allocation_mutex_} in {NativeModule}, and {mutex_} in {WasmCodeAllocator}. This caused problems with lock order inversion. This CL thus merges the two mutex, by always locking the mutex in {NativeModule} when calling a non-atomic method in {WasmCodeAllocator}. This serializes slightly more code, but none of this should be performance-critical. This removes the awkward {OptionalLock} class and adds the "Locked" suffix to a few methods to document that those can only be called while holding the allocation mutex.

The mechanisms don't interact well. NodeObserver assumes synchronous compilation that finishes within the ObserverNodeScope. One could ensure all relevant lifetimes (of the NodeObserver itself, and all captured pointers) exceed that of all spawned jobs, but simply disabling the additional concurrent job in these cases is a pragmatic fix for now.

This reverts commit d16eefe0. It is not correct to check for node equality during the graph construction phase, because we can have optimizations that will combine same nodes. So it can happen that in wasm-compiler, the inputs to shuffle are not the same, so we canonicalize using that knowledge that it will not be the same, and allow indices > 15. But later we can have optimizations that combine the 2 inputs (e.g. splat of the same constants), and the instruction selector will see that the input nodes are the same.

This reverts commit 6124a534. Reason for revert: On suspicion of blocking V8 roll: https://ci.chromium.org/ui/p/chromium/builders/try/win10_chromium_x64_rel_ng/839568/overview Original change's description: > [fastcall] Add support for leaf interface type checks > > This CL adds an IsTemplateForApiObject method to FunctionTemplate > allowing the embedder to check whether a given API object was > instantiated by this template without including parent templates > in the search. It also replaces the v8::ApiObject in the fast API > with a raw v8::Value pointer to allow use of standard C++ casts. > > Bug: chromium:1052746 > Change-Id: I0812ec8b4daaa5f5005aabf10b63e1e84e0b8f03 > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2595310 > Commit-Queue: Maya Lekova <mslekova@chromium.org> > Reviewed-by: Georg Neis <neis@chromium.org> > Reviewed-by: Camillo Bruni <cbruni@chromium.org> > Reviewed-by: Sathya Gunasekaran <gsathya@chromium.org> > Cr-Commit-Position: refs/heads/master@{#73999} Bug: chromium:1052746 Change-Id: Ic99ec616310f0f75800c3dad393b5d2d685b76ab No-Presubmit: true No-Tree-Checks: true No-Try: true Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2829988 Auto-Submit: Shu-yu Guo <syg@chromium.org> Commit-Queue: Rubber Stamper <rubber-stamper@appspot.gserviceaccount.com> Bot-Commit: Rubber Stamper <rubber-stamper@appspot.gserviceaccount.com> Cr-Commit-Position: refs/heads/master@{#74016}
