This changes ArrayBufferTracker to count array buffer byte length instead of allocation length. Byte length better approximates actual memory pressure because it refers to how many bytes are actually committed, whereas for allocation length, these bytes may be reserved but not committed. Note that we still need to be careful about address space exhaustion. Most address space is used by WebAssembly's guard regions. These are now managed by WasmMemoryTracker to ensure we do not consume too much address space. As a side effect, this CL fixes v8:7576 because byte_length() does not need to access the is_wasm_memory field whereas allocation_length() does.

Peter Marshall authored
For mode = kArrayFunction, we know that we need to call the array constructor stub, so we don't need to read it out from the construct_stub field. We also don't need to set it in the construct_stub field anymore, so just use the builtins constructor stub like other builtins. Also cleans up PushArgsThenCall by adding a dcheck that we are never in mode = kArrayFunction, so we don't even try to generate code for this case, but fail earlier instead. We don't need to load the array function in ArrayConstructor because this is set up for us by the builtins construct stub. We do have to check if new_target is actually set before overwriting it with target, as we are handling both call and construct cases in ArrayConstructor now.

Benedikt Meurer authored
In Promise.all we used to allocate a fresh closure plus a fresh context for each individual element, which is quite a lot of overhead, especially since this could be shared in a single context for all elements. The only bit of information that is needed for each resolve element closure is the index under which to store the resulting value. With this change we move this index to the "identity hash" field of the JSFunction, which doesn't care about the concrete value anyways, as long as it's not zero (the "no hash" sentinel), and share the rest of the fields in a single outer context for all resolve element closures. This limits the maximum number of elements for Promise.all to 2^21 for now, but that should be fine. Shall we ever see the need for more than this, we can add machinery to overflow to separate context for indices larger than 2^21. This significantly reduces the overhead due to Promise.all on the parallel-async-es2017-native test, with execution time dropping from around 148ms to 133ms, so overall a steady 10% improvement on this benchmark.

... and some more cleanup. The main change is that NativeModule::CloneCode does not relocate the new code. Wasm functions can only call other trampolines or stubs, or other wasm functions. Both of these targets are patched later anyway. This also fixes a bug on arm architectures, where the new call target (after RelocInfo::apply) could not be encoded in the instruction correctly. Now the relocation and the patching happen in one step, avoiding this problem.

This CL also deprecates V8::RegisterDefaultSignalHandler. Now instead of using the old API, clients should call V8::EnableWebAssemblyTrapHandler. Just setting the --wasm-trap-handler flag will no longer have any effect.

Using a 256-byte buffer avoids 99% of allocations across v8's top25 benchmark. This also leads to a significant performance increase on speedometer, with a ~1.2% improvement on jQuery, ~1.3% on VanillaJS and an overall ~0.4% improvement on the score.

This introduces masking of loads with speculation bit during code generation. At the moment, this is done only under the --branch-load-poisoning flag, and this CL enlarges the set of supported platforms from {x64, arm, arm64} to {x64, arm, arm64, mips, mips64}. Overview of changes: - new register configuration configuration with one register reserved for the speculation poison/mask (kSpeculationPoisonRegister). - in codegen, we introduce an update to the poison register at the starts of all successors of branches (and deopts) that are marked as safety branches (deopts). - in memory optimizer, we lower all field and element loads to PoisonedLoads. - poisoned loads are then masked in codegen with the poison register. (In this CL, this last step is left as a TODO. You can run with the flag, though mitigations will just not be effective at this time). * only integer loads are masked at the moment.

The tick-processor expects a certain format for functions in d8's cpu profile log (--prof). To make wasm functions look like js functions, this change adds a fake address to the log output that can be used as key for the wasm function. This enables basic profiling of wasm code using the --prof flag and the tick-processor.
