CreateFrameFromInternal always creates StackFrame from the frame at the index zero, which is fine for the usage in Trap::origin, but is a bug for Trap::trace Change-Id: Ia9471f600c5165ffc1c165b2f114b40acbe5b1e9 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2465353 Commit-Queue: Andreas Haas <ahaas@chromium.org> Reviewed-by:

On AVX, many instructions can have 3 operands, unlike SSE which only has 2. So on SSE we use DefineSameAsFirst on the dst. But on AVX, using that will cause some unnecessary moves. This patch changes a couple of F32x4 and S128 instructions to remove this restriction when AVX is supported. We can't use AvxHelper since it duplicates the dst for the call to the AVX instruction, which isn't what we want. The alternative is to redefine Mulps and other functions here, but there are other callsites that depend on this duplicated-dst behavior, so it's harder to change. We can migrate this as we move more logic over to non-DefineSameAsFirst for AVX. With the meshopt_decoder.js in the linked bug, it removes 8 SIMD movs (from a function that has 300+ lines of assembly.) Note that from agner's microarchitecture.pdf, page 127, "Elimination of move instructions", many times such moves can be eliminated by the processor. So this change won't speed up perf, but it helps a bit with binary size, and decoder pressure.

This CL prohibits using PopAndReturn from the builtins that have calling convention with arguments on the stack. This CL also updates the PopAndReturn tests so that even off-by-one errors in the number of poped arguments are caught which was not the case before. Motivation: PopAndReturn is supposed to be using ONLY in CSA/Torque builtins for dropping ALL JS arguments that are currently located on the stack. Disallowing PopAndReturn in builtins with stack arguments simplifies semantics of this instruction because in case of presence of declared stack parameters it's impossible to distinguish the following cases: 1) stack parameter is included in JS arguments (and therefore it will be dropped as a part of 'pop' number of arguments), 2) stack parameter is NOT included in JS arguments (and therefore it should be dropped in ADDITION to the 'pop' number of arguments). This issue wasn't noticed before because builtins with stack parameters relied on adapter frames machinery to ensure that the expected parameters are present on the stack, but on the same time the adapter frame tearing down code was effectively recovering the stack pointer potentially broken by the CSA builtin. Once we get rid of the arguments adapter frames keeping stack pointer in a valid state becomes crucial.

Fix a crash/hang that occurred when deleting a snapshot during the GC that is part of taking another one. Specifically, when deleting the only other snapshot in such a situation, the `v8::HeapSnapshot::Delete()` method sees that there is only one (complete) snapshot at that point, and decides that it is okay to perform “delete all snapshots” instead of just deleting the requested one. That resets the internal string lookup table of the heap profiler, but the new snapshot that is currently in progress still holds references to the old string lookup table, leading to a use-after-free segfault or infinite loop. Fix this by guarding against resetting the string table while another heap snapshot is being taken, and add a test that would crash before this fix. This can be triggered in Node.js by repeatedly calling `v8.getHeapSnapshot()`, which provides heap snapshots as weakly held host objects.

Adds a cross-thread reference for strongly and weakly retaining objects on a thread other than the thread that owns the object. The intended use of the reference is by setting it up on the originating thread, holding the object alive from another thread, and ultimately accessing the object again on the originating thread. The reference has known caveats: - It's unsafe to use when the heap may terminate; - It's unsafe to transitively reach through the graph because of compaction; Change-Id: I84fbdde69a099eb54af5b93c34e2169915b17e64 Bug: chromium:1056170 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2436449 Commit-Queue: Michael Lippautz <mlippautz@chromium.org> Reviewed-by:

Always install the Abort builtin first, because heap validation might get triggered while we compile the wasm-to-js wrapper, and it would find an illegal WasmJSFunctionData object otherwise.
