This CL enables adding code to the top-most {WasmCodeRefScope} when either adding code to the {NativeModule} (we have a nice choke point for that in {PublishCodeLocked}), or when looking up existing code from a {NativeModule}.

When TurboFan optimizes field access, we need to check first that the runtime already determined the correct field representation properly. If the field representation is still None, we cannot optimize this in TurboFan straight away but we have to call the IC to let the runtime do the magic.

With lazy feedback allocation we load the interrupt budget from the ClosureFeedbackCellArray instead of the bytecode array. The factory method that constructs the ClosureFeedbackCellArray ensures we have a field for interrupt budget. So, it is safe to omit bounds check here. Including the bounds check increases the size of all jump bytecode handlers by around ~120 bytes. This translates to ~9-10KB of the native code size on Android.

Michael Starzinger authored
This adds preliminary support for handling the "br_on_exn" opcode in the interpreter. It also makes "catch" and "rethrow" use a proper exception reference instead of a dummy value. To that end this also adds {Handle<>} as a new kind of {WasmValue} which is intended to pass reference values (e.g. "anyref" or "except_ref") to the runtime system. Therefore lifetime of such a {WasmValue} is directly coupled to any surrounding {HandleScope}. For now we just store {Handle<>} directly on the simulated operand stack of the interpreter. This is of course bogus, since the surrounding scope does not outlive the interpreter activation. Decoupling the lifetime of the operand stack from a {HandleScope} will be done in a follow-up CL. As a drive-by this change also implements support for the "ref_null" and the "ref_is_null" opcodes as a proof-of-concept that the new {WasmValue} is also applicable to the "anyref" reference type.

This reverts commit d746be9c. Reason for revert: Speculative revert because this CL *might* cause timeouts on several bots: https://ci.chromium.org/p/v8/builders/ci/V8%20Linux%20-%20predictable/23351 Original change's description: > [wasm] Use work-stealing queues for background compilation > > This reduces contention on the mutex protecting the {CompilationState} > by splitting the compilation unit queues into several queues (one per > background task). Each task executes its own queue first, and steals > from other queues once it runs out of work. > The implementation of the set of work-stealing queues is encapsulated > in the new {CompilationUnitQueues} class in module-compiler.cc. > > R=titzer@chromium.org > > Bug: v8:8916 > Change-Id: I5a40314917e7d4a35d7ff9e8ec124ec212beacab > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1543350 > Commit-Queue: Clemens Hammacher <clemensh@chromium.org> > Reviewed-by: Michael Starzinger <mstarzinger@chromium.org> > Cr-Commit-Position: refs/heads/master@{#60572} TBR=mstarzinger@chromium.org,titzer@chromium.org,clemensh@chromium.org Change-Id: I92d8862ec0ff0002160a62ed9df9b044fc95c93d No-Presubmit: true No-Tree-Checks: true No-Try: true Bug: v8:8916 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1549166Reviewed-by:

... which doesn't respect address hints when reserving an address space region and therefore makes it impossible to fulfill V8 heap alignment requirements. As a workaround we just overreserve address space to ensure that we will be able to find a properly aligned 4GB subregion.
