This CL renames a number of things related to the V8 sandbox. Mainly, what used to be under V8_HEAP_SANDBOX is now under V8_SANDBOXED_EXTERNAL_POINTERS, while the previous V8 VirtualMemoryCage is now simply the V8 Sandbox: V8_VIRTUAL_MEMORY_CAGE => V8_SANDBOX V8_HEAP_SANDBOX => V8_SANDBOXED_EXTERNAL_POINTERS V8_CAGED_POINTERS => V8_SANDBOXED_POINTERS V8VirtualMemoryCage => Sandbox CagedPointer => SandboxedPointer fake cage => partially reserved sandbox src/security => src/sandbox This naming scheme should simplify things: the sandbox is now the large region of virtual address space inside which V8 mainly operates and which should be considered untrusted. Mechanisms like sandboxed pointers are then used to attempt to prevent escapes from the sandbox (i.e. corruption of memory outside of it). Furthermore, the new naming scheme avoids the confusion with the various other "cages" in V8, in particular, the VirtualMemoryCage class, by dropping that name entirely. Future sandbox features are developed under their own V8_SANDBOX_X flag, and will, once final, be merged into V8_SANDBOX. Current future features are sandboxed external pointers (using the external pointer table), and sandboxed pointers (pointers guaranteed to point into the sandbox, e.g. because they are encoded as offsets). This CL then also introduces a new build flag, v8_enable_sandbox_future, which enables all future features.

This is the final change list in the list of refactorings to split off the implementations of v8::StackFrame and CallSite objects (as used by the V8 JavaScript stack API). See https://bit.ly/v8-stack-frame for the whole story. This CL adds the v8::internal::StackFrameInfo class as new backing implementation of v8::StackFrame, and puts it into debug-objects.tq to indicate that it's used for the debugger API only. This new class is lightweight and only holds on to static information about the stack frame, and is thus usable for the V8 inspector to implement async stack traces in a cheaper manner going forward.

On some branches of the search tree for a binary-search switch, the input value is sufficiently constrained that we could unconditionally jump to the last possible case rather than checking for value equality. This shortens some builtins by a few instructions and might speed things up, though I expect the effect to be small.

Seth Brenith authored
We probably expect a binary-search switch to take log(n) time in all cases, but there is currently a possibility of that expectation being broken. I'm not aware of any place where this actually happens, but if the default handler immediately follows the switch dispatch block in assembly order, then unconditional jump instructions for that handler would be omitted. This omission could cause linear execution time, where every case is checked before falling through to the default handler. This change introduces a new function to emit an unconditional jump instruction regardless of whether the target is the following block, and uses that new function when generating a binary-search switch to ensure consistently log(n) behavior.

This is a non-functional refactoring to make naming of stack traces more consistent, and thus easier to reason about whether the "simple stack trace" (stack trace API) or the "detailed stack trace" (inspector API) is meant. Granted, these names aren't great by themselves, but at least we should be consistent. This also adds a new `Isolate::GetSimpleStackTrace()` and uses that directly to implement the Wasm C-API, avoiding the roundtrip via the `JSMessageObject`, which actually carries a detailed stack trace (which by chance worked out so far).

This is the second step in the refactoring to make v8::StackFrame more lightweight and usable for (long time storage) by the V8 inspector (see https://bit.ly/v8-stack-frame for an overview). This is a purely mechanical change without any functional aspects. The intention is to make the use case for the CallSiteInfo objects clear, namely to serve as the backing store for the CallSite objects exposed via the Error.prepareStackTrace() API and used under the hood to implement the error.stack accessor.

This is a reland of 863bc2b8 Diff to original: - Don't eliminate GC observable stores that were temporarily unobservable during traversal. - Skip the previously added test for single-generation - Add new test Original change's description: > [turbofan] Improve StoreStoreElimination > > Previously, StoreStoreElimination handled allocations as > "can observe anything". This is pretty conservative and prohibits > elimination of repeated double stores to the same field. > With this CL allocations are changed to "observes initializing or > transitioning stores". > This way it is guaranteed that initializing stores to a freshly created > object or stores that are part of a map transition are not eliminated > before allocations (that can trigger GC), but allows elimination of > non-initializing, non-transitioning, unobservable stores in the > presence of allocations. > > Bug: v8:12200 > Change-Id: Ie1419696b9c8cb7c39aecf38d9f08102177b2c0f > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3295449 > Commit-Queue: Patrick Thier <pthier@chromium.org> > Reviewed-by: Tobias Tebbi <tebbi@chromium.org> > Reviewed-by: Maya Lekova <mslekova@chromium.org> > Cr-Commit-Position: refs/heads/main@{#78230} Bug: v8:12200, chromium:1276923, v8:12477 Change-Id: Ied45ee28ac12b370f7b232d2d338f93e10fea6b4 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3320460Reviewed-by:

This is a reland of 2418d22a Reland fixes: * Rebase this 2+ year old change
😱 * Unpoison the kept segment before zapping it to make ASAN happy. * Carefully adjust allocation size tracking fields to compensate for kept segment.

This CL overrides the Summarize() method on the BuiltinExitFrame, similar to what is already implemented on UnoptimizedFrame. This way the stack trace capturing logic can be unified further, and only needs to distinguish between JavaScript(ish) and WebAssembly frames now.
