      PPC: [turbofan] Run everything after representation selection concurrently. · 98b074cb
      bjaideep authored 
      Port d1b3d426

Original commit message:

    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.

      PPC: [Interpreter] Make dispatch table point to code entry instead of code objects. · 6c702283
      mbrandy authored 
      Port 0c05e02f

Original commit message:
    Modifies Ignition to store code entry addresses in the dispatch table
    rather than code objects. This allows the interpreter to avoid
    calculating the code entry address from the code object on every
    dispatch and provides a ~5-7% performance improvement on Octane with
    Ignition.

    This change adds ArchOpcode::kArchTailCallAddress to TurboFan to enable
    tail call dispatch using these code addresses. It also adds a Dispatch
    linkage creator (distinct from the stub linkage type used previously) to
    allow targetting a code address target (which will diverge further from
    the stub linkage type when we remove the context machine register in
    Ignition).

      PPC: [Atomics] code stubs for atomic operations · 89e9819c
      mbrandy authored 
      Port 5e9ddf6c

Original commit message:
    * New atomic code stubs for x64, ia32, arm, arm64
    * Add convenience functions JumpIfNotValidSmiValue, JumpIfUintNotValidSmiValue
      to macro-assembler-ia32 (API based on x64 macro assembler)
    * Remove runtime implementation of Atomics.load, the code stub should always be
      called instead
    * Add new test to mjsunit atomics test; check that Smi values of different
      sizes are supported when possible, else fall back to HeapNumbers

    These changes were needed to add another codestub:
    * Bump kStubMajorKeyBits from 7 to 8
    * Reduce ScriptContextFieldStub::kSlotIndexBits from 13 to 12

      PPC: [generators] Decouple generator resume from fullcodegen. · 1e001e71
      mbrandy authored 
      Port 974721c6

Original commit message:
    Introduce a ResumeGeneratorTrampoline, which does the actual stack state
    reconstruction (currently always restores a fullcodegen frame), and
    introduce appropriate TurboFan builtins for %GeneratorPrototype%.next,
    %GeneratorPrototype%.return and %GeneratorPrototype%.throw based on
    this native builtin.

    Also unify the flooding in case of step-in to always work based on
    JSFunction and remove the special casing for JSGeneratorObject.

      Use a dictionary-mode code cache on the map rather than a dual system. · d2eb555e
      verwaest authored 
      The previous code cache system required stubs to be marked with a StubType, causing them to be inserted either into a fixed array or into a dictionary-mode code cache. This could cause names to be in both cases, and lookup would just find the "fast" one first. Given that we clear out the caches on each GC, the memory overhead shouldn't be too bad. Additionally, the dictionary itself should just stay linear for small arrays; that's faster anyway.

This CL additionally deletes some dead IC code.
