      [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 StringAddStub to TF · 787157dd
      danno authored 
      In the process:
- Add ToString to the CodeStubAssembler and use it where appropriate
- Add constant-folding versions of IntPtrAdd/IntPtrSub to simplify code
  in element offset computation, especially for strings.

      [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.

      Move kMaxRegularHeapObjectSize into globals · 059b5643
      mlippautz authored 
      This way we avoid the cyclic dependency between objects.h and heap.h and still
have one definition. Add a static assert that this size is indeed smaller than
the payload of a page.

Follow ups can finally remove the dependency on spaces.h for all heap.h users.

      Forking the type system between Crankshaft & Turbofan. · 17e9e2f4
      mvstanton authored 
      Our Type class has a semantic and representational dimension.
Much code in src/ast, Crankshaft and Turbofan is based on it.
Going forward in Turbofan we'd like to remove representational information
entirely. To that end, new type AstType has been created to preserve
existing behavior for the benefit of Crankshaft and the AST.

      [stubs] Convert GrowElementsStub to TurboFan · eb841269
      danno authored 
      One caveat: the Crankshaft stub used to preserve callee-clobbered double
registers, which is contrary to any real platform ABI that we support. Since the
only current use of this stub is in Crankshaft, the instruction there now must
be marked as double-clobbering. This might result in a small performance
regression. However, when this stub is eventually used in TF-generated code, it
will be called from deferred code that can save doubles only on the rarely-taken
path... something that Crankshaft can't do.

      Add a flag to help platform ports bootstrap V8 · c07c675e
      danno authored 
      A "--minimal" flag turns off all optimizing compilers and activates the
interpreter. The idea is that with this flag activated, only the
platform-specific stubs and a Turbofan implementation must be complete to start
d8 and run the bulk of the tests. Note that although this flag is constructed as
a runtime flag, it must be set to true when building the snapshot and therefore
creates a compile-time dependency.

      [stubs] Port CreateWeakCellStub to turbofan · 7f1fa30e
      danno authored 
      In the process also inline the stub into the appropriate interpreter bytecode
handler and make sure that the context register is preserved in hand-written
assembly code that calls the stub and expects the context register to be
preserved.

      [turbofan] Add support for eager/soft deoptimization reasons. · db635d5b
      bmeurer authored 
      So far TurboFan wasn't adding the deoptimization reasons for eager/soft
deoptimization exits that can be used by either the DevTools profiler or
the --trace-deopt flag. This adds basic support for deopt reasons on
Deoptimize, DeoptimizeIf and DeoptimizeUnless nodes and threads through
the reasons to the code generation.

Also moves the DeoptReason to it's own file (to resolve include cycles)
and drops unused reasons.
