      [regexp] Port RegExpExecStub to CSA (mostly) · 5cc61896
      jgruber authored
      This moves most of the logic contained in RegExpExecStub to CSA.  Benefits are
      mostly easier readability and hackability, and removal of a large chunk of
      platform-specific assembly.
      
      Exit frame construction and the final call remain in RegExpExecStub.

      [liveedit] reimplement frame restarting. · 3f47c63d
      yangguo authored
      Previously, when restarting a frame, we would rewrite all frames
      between the debugger activation and the frame to restart to squash
      them, and replace the return address with that of a builtin to
      leave that rewritten frame, and restart the function by calling it.
      
      We now simply remember the frame to drop to, and upon returning
      from the debugger, we check whether to drop the frame, load the
      new FP, and restart the function.

      [turbofan] Introduce JSCallForwardVarargs operator. · 69747e26
      bmeurer authored
      We turn a JSCallFunction node for
      
        f.apply(receiver, arguments)
      
      into a JSCallForwardVarargs node, when the arguments refers to the
      arguments of the outermost optimized code object, i.e. not an inlined
      arguments, and the apply method refers to Function.prototype.apply,
      and there's no other user of arguments except in frame states.
      
      We also replace the arguments node in the graph with a marker for
      the Deoptimizer similar to Crankshaft to make sure we don't materialize
      unused arguments just for the sake of deoptimization. We plan to replace
      this with a saner EscapeAnalysis based solution soon.

      [TypeFeedbackVector] Root literal arrays in function literals slots · 93df0940
      mvstanton authored
      Literal arrays and feedback vectors for a function can be garbage
      collected if we don't have a rooted closure for the function, which
      happens often. It's expensive to come back from this (recreating
      boilerplates and gathering feedback again), and the cost is
      disproportionate if the function was inlined into optimized code.
      
      To guard against losing these arrays when we need them, we'll now
      create literal arrays when creating the feedback vector for the outer
      closure, and root them strongly in that vector.

      [regexp] Remove unused code · 77ddcfb3
      jgruber authored
      This CL removes code that is now unused since the port of regexp.js has been
      completed. Removed functions / classes are:
      
      * regexp.js (GetSubstitution moved to string.js)
      * RegExpConstructResult stub
      * RegExpFlags intrinsic
      * RegExpSource intrinsic
      * RegExpInitializeAndCompile runtime function

      [stubs] Port StoreTransitionStub and ElementsTransitionAndStoreStub to TurboFan. · 130d9893
      ishell authored
      This CL also cleans up related interface descriptors:
      1) unused StoreTransitionDescriptor is removed and VectorStoreTransitionDescriptor is
      renamed to StoreTransitionDescriptor.
      2) on ia32/x87 architectures slot and vector are passed on the stack (dispatcher/handlers
      cleanup will be addressed in a separate CL).
      
      These two stub ports have to be combined in one CL because:
      1) without changing the StoreTransitionDescriptor TF was not able to compile them
      on ia32/x87 (because of lack of registers),
      2) it was not possible to change the descriptor first because Crankshaft was not able
      to deal with the stack allocated parameters in case of a stub failure.

      [es6] Reintroduce the instanceof operator in the backends. · 551e0aa1
      bmeurer authored
      This adds back the instanceof operator support in the backends and
      introduces a @@hasInstance protector cell on the isolate that guards the
      fast path for the InstanceOfStub. This way we recover the ~10%
      regression on Octane EarleyBoyer in Crankshaft and greatly improve
      TurboFan and Ignition performance of instanceof.

      [turbofan] Run everything after representation selection concurrently. · d1b3d426
      bmeurer authored
      Further refactor the pipeline to even run the first scheduler (part of
      the effect control linearization) concurrently. This temporarily
      disables most of the write barrier elimination, but we will get back to
      that later.
      
      Drive-by-fix: Remove the dead code from ChangeLowering, and stack
      allocate the Typer in the pipeline. Also migrate the AllocateStub to a
      native code builtin, so that we have the code object + a handle to it
      available all the time.
