The CPPGC_BUILD_IN_V8 define (used for tracing) isn't propagated from v8_base_without_compiler to cppgc_base, which breaks build with perfetto. Instead use a gn args to specify standalone builds (defaulted to false) and use that to choose the right tracing implementation.

Prototype 2 prefetch instructions (temporal and non-temporal) on arm64 and interpreter. Add prfm to assembler, and use MiscField to encode the two versions. Small tweak to simulator to handle these new instructions (no-op). The implementation in the interpreter just pops the memory index and does nothing. Simple test cases added for these 2 new instructions, as well as a prefetch with OOB index, which should not trap.

In our codegen, we are mixing SSE and AVX. This can potentially cause transition delays. Ideally we should stick to one. We add some new AVX versions of movss and movsd, then use the macro-assembler methods to generate AVX instructions if supported.

With pointer compression, the size of a reference depends on whether it is stored on the stack or on the heap. The size provided by ValueType::element_size_bytes() is the size of a reference on the heap. LiftoffAssembler::SlotSizeForType(...) however should return the size on the stack. This CL fixes this inconsistency. This issue would have been found by an existing test, but this test is disabled at the moment because of missing safepoint maps for stack checks.

Because of LocalHeap safepoints, our existing assert scopes don't necessarily maintain the same guarantees as desired. In particular, DisallowHeapAllocation no longer guarantees that objects don't move. This patch transitions DisallowHeapAllocation to DisallowGarbageCollection, to ensure that code using this scope is also protected against safepoints.

This retrieves script name directly from StackFrameBase, bypassing building of StackFrameInfo if one hasn't already been initialized, thus avoiding computation of expensive properties that are not required. This matches current behavior of GetScriptNameOrSourceURL() and is a workaround until a dedicated API is available. This is necessary to switch AdTagging over from using GetScriptNameOrSourceURL() to GetScriptName(), to ensure that scripts with source urls are tagged appropriately. (See crrev.com/c/2551259.)

Port 1da429fb Original Commit Message: This is a reland of 800307f6, with a minimal fix for arm64 (uint64_t -> uintptr_t). Original change's description: > [wasm][memory64] Prepare Liftoff for ptrsize offsets > > This CL prepares the LiftoffAssembler interface for uintptr_t offsets. > Many places can still only handle 32-bit values, but after this CL we can > start storing the offsets as uintptr_t in the memory access immediates. > Some TODOs are placed to extend code generation for 64-bit additions, if > memory64 is enabled. > All of this will be addressed in follow-up CLs. > > R=manoskouk@chromium.org > > Bug: v8:10949 > Change-Id: Id3b9b8aa555ab41f082ba012f4f8d80586c35b89 > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2529452 > Commit-Queue: Clemens Backes <clemensb@chromium.org> > Reviewed-by: Manos Koukoutos <manoskouk@chromium.org> > Cr-Commit-Position: refs/heads/master@{#71236} R=clemensb@chromium.org, joransiu@ca.ibm.com, junyan@redhat.com, midawson@redhat.com BUG= LOG=N Change-Id: I87a421ab1fe6e4d0f2098c24ff34a3888631722e Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2552166Reviewed-by:
