At the moment deserialization happens synchronously on the main thread. This is fine at the moment because deserialization is fast. However, future refactorings may affect deserialization time, and may force us to deserialize in the background. This CL adds a timer to monitor deserialization time, so that we get a signal if deserialization time regresses.

Replace all uses of NewArray/DeleteArray with new[]/delete[] in utils/vector.h which allows removing the dependency on utils/allocation.h. As a result allocation failures here will not call FatalProcessOutOfMemory any more, but it's likely it wouldn't have been called anyway. Also adds some missing includes that were being previously being brought in via vector.h depending on allocation.h.

WebAssembly.Exception is the static representation of a wasm exception. It holds the signature and the tag of the exception, can be imported and exported from a wasm module, and will eventually allow inspecting a wasm-thrown exception from JS.

When pushing/popping registers, we need a way in PPC and S390 to detect if Simd registers need to be pushed or not. On PPC Simd registers are separate from FP registers, hence we need to push them both. If Simd is not available then we push an empty space in place of Simd registers. On S390 the Simd and FP registers are shared. If Simd is available then we only push them and not the FPs, else we push FP registers as well as an empty space the size of FPs as the stack needs to look like as if Simds were saved too. We also need to check if we are generating builtins or call is being made at runtime. We cannot use `SupportsWasmSimd128` when generating builtin as `CpuFeatures` are turned off, so we need to emit the `if/else` manually for checking the value of `SupportsWasmSimd128`.

Rather than letting a recursive macro expansion cause a stack overflow and crash the compiler, this change updates Torque to emit an error as soon as the recursion is detected. Eventually it would be nice to make Cast macros a little more magical so they don't require so much human effort to maintain, but at least this way Torque displays some information about what went wrong. An example error message (manually wrapped to 72 character width) follows. src/builtins/cast.tq:157:10: Torque Error: Recursive macro call to callable Cast<(class Context | Undefined | Zero)>(implicit class Context)(Object): (class Context | Undefined | Zero) src/builtins/cast.tq:758:3: Torque Error: Note: in specialization Cast<(class Context | Undefined | Zero)> requested here src/builtins/cast.tq:764:10: Torque Error: Note: in specialization Is<(class Context | Undefined | Zero), Object> requested here src/builtins/torque-internal.tq:64:3: Torque Error: Note: in specialization UnsafeCast<(class Context | Undefined | Zero)> requested here src/objects/contexts.tq:75:10: Torque Error: Note: in specialization ReferenceCast<(class Context | Undefined | Zero), Object> requested here src/builtins/iterator.tq:142:16: Torque Error: Note: in specialization ContextSlot<class Context, class Context, (class Context | Undefined | Zero)> requested here Bug: v8:11727 Change-Id: I7b5b1852dee16a6860f593f27783f6b2d9366146 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2965032Reviewed-by:

On a loop back edge both the cached instance and the cached memory start have to get restored for the next loop iteration. In the original CL we did not consider the case that by restoring the instance we may overwrite the currently cached memory start. Original description: WebAssembly functions often have subsequent memory accesses, and each of these memory accesses need the start address of the memory in a register. With this CL the register with the memory start address is cached, so only the first memory access has to load the memory start address into a register, subsequent memory accesses can just reuse the register. In first measurements with the epic benchmark this reduces the size of the generated Liftoff code by a bit more than 5%.
