      [debug] Untangle DebugInfo from break point support · d3371c23
      jgruber authored 
      DebugInfo was very closely tied to break point support:
* It contained only information relevant to break points.
* It was created and freed by break point implementation.
* Existence of a DebugInfo on the shared function info implied existence of
  break points.

This CL is a step towards making DebugInfo usable by other debugging
functionality such as block coverage by decoupling it from break point support,
which is now only one kind of information stored on the DebugInfo object.

      [compiler] Delay allocation of code-embedded heap numbers. · 659e8f7b
      neis authored 
      Instead of allocating and embedding certain heap numbers into the code
during code assembly, emit dummies but record the allocation requests.
Later then, in Assembler::GetCode, allocate the heap numbers and patch
the code by replacing the dummies with the actual objects. The
RelocInfos for the embedded objects are already recorded correctly when
emitting the dummies.

      [gn] Allow building a snapshot with unwinding information. · 73ab0f4b
      pierre.langlois authored 
      Add a new "v8_perf_prof_unwinding_info" option to gn that translates to building
the snapshot with "--perf-prof-unwinding-info". It allows unwinding TF generated
code from the snapshot.

Additionally, add a warning if one uses the option along with a snapshot which
was not build with unwinding information.

Running tests in this configuration revealed an issue in the checks performed
when accessing the stub cache. We would assume that the `Code::Flags` bitfield
only contains the `Kind` and `ExtraICState` fields, when there is also a
`HasUnwindingInfo` field which can now be set for stubs.

      PPC/s390: [stubs] Drop CallApiCallbackStub::call_data_undefined optimization. · 33687698
      bjaideep authored 
      Port 46d0e481

Original Commit Message:

    The CallApiCallbackStub can avoid loading undefined in case the
    call_data is already undefined, which doubles the number of versions of
    the stub and adds unnecessary complexity (at the benefit of saving one
    stupid load). The idea is to turn the CallApiCallbackStub into a single
    builtin instead, which does the right thing, so this is the first step
    towards that goal.

      Fix static initializer in ic.cc · df0eaff4
      thestig authored 
      This was added in commit 40611, but the std::cout calls are gone so the
header is no longer needed.

Remove trailing spaces in html files rom the same commit and from other
html files in the same directory.

      Reland: [Interpreter] Move BinaryOp Smi transformation into BytecodeGenerator."" · 496864f8
      Ross McIlroy authored 
      This relands commit d3e9aade. The original CL was reverted speculatively but didn't cause the buildbot failure.

Original change's description:
> [Interpreter] Move BinaryOp Smi transformation into BytecodeGenerator.
> 
> Perform the transformation to <BinaryOp>Smi for Binary ops which take Smi
> literals in the BytecodeGenerator. This enables us to perform the
> transformation for literals on either side for commutative operations, and
> Avoids having to do the check on every bytecode in the peephole optimizer.
> 
> In the process, adds Smi bytecode variants for all binary operations, adding
>  - MulSmi
>  - DivSmi
>  - ModSmi
>  - BitwiseXorSmi
>  - ShiftRightLogical
