      PPC/s390: [builtins] Introduce proper Float64Exp operator. · a54e289e
      bjaideep authored
      Port d5f2ac5e
      
      Original commit message:
      
          Import base::ieee754::exp() from FreeBSD msun and introduce a Float64Exp
          TurboFan operator based on that, similar to what we do for Float64Log.
          Rewrite Math.exp() as TurboFan builtin and use that operator to also
          inline Math.exp() into optimized TurboFan functions.

      PPC: [runtime] Unify and simplify how frames are marked · 4445c095
      mbrandy authored
      Port 9dcd0857
      
      Original commit message:
          Before this CL, various code stubs used different techniques
          for marking their frames to enable stack-crawling and other
          access to data in the frame. All of them were based on a abuse
          of the "standard" frame representation, e.g. storing the a
          context pointer immediately below the frame's fp, and a
          function pointer after that. Although functional, this approach
          tends to make stubs and builtins do an awkward, unnecessary
          dance to appear like standard frames, even if they have
          nothing to do with JavaScript execution.
      
          This CL attempts to improve this by:
      
          * Ensuring that there are only two fundamentally different
            types of frames, a "standard" frame and a "typed" frame.
            Standard frames, as before, contain both a context and
            function pointer. Typed frames contain only a minimum
            of a smi marker in the position immediately below the fp
            where the context is in standard frames.
          * Only interpreted, full codegen, and optimized Crankshaft and
            TurboFan JavaScript frames use the "standard" format. All
            other frames use the type frame format with an explicit
            marker.
          * Typed frames can contain one or more values below the
            type marker. There is new magic macro machinery in
            frames.h that simplifies defining the offsets of these fields
            in typed frames.
          * A new flag in the CallDescriptor enables specifying whether
            a frame is a standard frame or a typed frame. Secondary
            register location spilling is now only enabled for standard
            frames.
          * A zillion places in the code have been updated to deal with
            the fact that most code stubs and internal frames use the
            typed frame format. This includes changes in the
            deoptimizer, debugger, and liveedit.
          * StandardFrameConstants::kMarkerOffset is deprecated,
            (CommonFrameConstants::kContextOrFrameTypeOffset
            and StandardFrameConstants::kFrameOffset are now used
            in its stead).

      Contribution of PowerPC port (continuation of 422063005) - uplevel · 45e4a789
      michael_dawson authored
      Contribution of PowerPC port (continuation of 422063005,
      817143002,866843003, and 901083004). This patch updates
      the ppc directories to make them current with changes in
      common code as of today.
      
      We had to exclude the test test-serialize/SerializeInternalReference
      until we agree on the right way to add those changes for PPC as
      outlined in the description in the google doc provided earlier.
      
      We also had to exclude a couple of other tests due to new
      failures seen since the last uplevel.  We excluded as opposed
      to waiting until we could investigate to maximize the chance
      of getting PPC compiling in the google repos before new
      breaking changes are made.
      
      I'll note that before applying any of our changes the
      mozilla part of quickcheck was already broken when using
      the lastest repo content so I had to run without that

      Contribution of PowerPC port (continuation of 422063005) - PPC dir update · 308d913a
      michael_dawson authored

      This patch brings the ppc directories up to date with our repo. We have
      removed 5 individual optimizations which require changes in both the ppc and common
      directories so they can be more easily reviewed on their own in subsequent patches.
      
      Subsequent patches will cover:
      - individual optimizations for PPC (5)
      - remaining AIX changes not resolved by 4.8 compiler (4.8 is only recently available
      for AIX)
      - incremental updates required to ppc directories due to platform specific changes
      made in google repos while we complete the above steps.
      
      With the update there are still some timeouts seen when run in simulated mode which
      may be a result of the missing optimizations.  Once we have the optimizations in
      we will review the simulation results and address/exclude tests as necessary so that
      the simulated runs are clean.
