      PPC/s390: [cleanup] Remove dead code from DeclareLookupSlot and rename it · 97ae43ac
      bjaideep authored 
      Port cbc6adc8

Original commit message:

    Runtime_DeclareLookupSlot is used when generating code for var and function declarations
    originating in an eval. Over time, it's accumulated quite a bit of cruft, which this CL removes:

      - With legacy const gone, lookup slots never have any property attributes.
      - There was a bit signaling that the variable was from an eval, but that was redundant since
        DeclareLookupSlot is only used for eval.
      - Some Proxy-related code didn't make sense here.

    Its name was also not terribly clear: while "LookupSlot" is used in several places, this
    particular function is only used for declaring variables and functions inside sloppy eval.
    Renamed (and split into two) to make this clear for future archeologists.

    Also added various DCHECKs to check the assumptions being made.

      PPC/s390: [wasm] Separate compilation from instantiation · 8071e21c
      bjaideep authored 
      Port c1d01aea

Original commit message:

    Compilation of wasm functions happens before instantiation. Imports are linked afterwards, at instantiation time. Globals and memory are also
    allocated and then tied in via relocation at instantiation time.

    This paves the way for implementing Wasm.compile, a prerequisite to
    offering the compiled code serialization feature.

    Currently, the WasmModule::Compile method just returns a fixed array
    containing the code objects. More appropriate modeling of the compiled module to come.

    Opportunistically centralized the logic on how to update memory
    references, size, and globals, since that logic is the exact same on each
    architecture, except for the actual storing of values back in the
    instruction stream.

      PPC/s390: [builtins] Introduce proper Float64Tan operator. · f1c2729d
      bjaideep authored 
      Port c87168bc

Original commit message:

    Import base::ieee754::tan() from fdlibm and introduce Float64Tan TurboFan
    operator based on that, similar to what we do for Float64Cos and Float64Sin.
    Rewrite Math.tan() as TurboFan builtin and use those operators to also
    inline Math.tan() into optimized TurboFan functions.

    Drive-by-fix: Kill the %_ConstructDouble intrinsics, and provide only
    the %ConstructDouble runtime entry for writing tests.

      This brings some more flags in line with the GYP build on Windows. In particular, this ads the SSE2 flag on x86, and the stack linker flag on x64.

      Refactor CpuProfiler. · cb59fc1f
      lpy authored 
      Currently CpuProfiler is a subclass of CodeEventListener, it listens code events
from Logger, constructs and stores CodeEventsContainer. This patch is part of
the effort to split the logic of CodeEventListener as ProfilerListener out of
the profiling functionality logic in CpuProfiler. A ProfilerListener will listen
to code events, construct code event to CodeEventsContainer and pass it to code
event handler.

The reason we refactor CpuProfiler is that eventually we want to move
CpuProfiler as part of sampler library and code event listener should stay
inside V8.

Main changes:
1. Refactored CpuProfiler into two parts, the CpuProfiler with profling
functionality and the ProfilerListener listening to code events from Logger.
2. Created CodeEventObserver and made CpuProfiler inherit from it.
ProfilerListener will have a list of observers and call CodeEventHandler once a
code event is created.
3. Moved code entry list from CodeEntry to ProfilerListener.

Minor changes:
1. Moved static code entry as part of CodeEntry.
2. Added ProfilerListener to Logger.
