      [turbofan] Make Node::set_op safer via wrapper. · da9c42dd
      mstarzinger authored 
      This introduces the NodeProperties::ChangeOp helper which guards node
operator changes so that additional checking can be done without any
additional dependencies being pulled into the Node class. For now only
the input count is checked, but additional checking might follow.

      [turbofan] Use appropriate type for NodeId. · c487aba7
      bmeurer authored 
      Up until now we used int32_t for NodeId, but that was not ideal because
negative values are invalid for NodeId and we use it as an array index
for example in the NodeMarker class, where C++ compilers on x64 have to
generate code that does proper sign extension for the indices, which is
completely unnecessary.

      [turbofan] Rework Node guts to save space. · 65b66634
      titzer authored 
      This reduces the storage per-Node storage from 7 words to 6 and per-edge
storage from 6 words to 4.
On average this is about 10%-15% space savings over the whole graph.

Remove the use of std::deque as the out-of-line storage for inputs.
Reduce size of Use links and use pointer arithmetic to find Node
from Use.

      [turbofan] Fix tail call optimization. · d21de2a4
      bmeurer authored 
      Tail calls are matched on the graph, with a dedicated tail call
optimization that is actually testable. The instruction selection can
still fall back to a regular if the platform constraints don't allow to
emit a tail call (i.e. the return locations of caller and callee differ
or the callee takes non-register parameters, which is a restriction that
will be removed in the future).

Also explicitly limit tail call optimization to stubs for now and drop
the global flag.

      [turbofan] Cleanup Graph and related classes. · e53845d4
      bmeurer authored 
      - Move NodeMarker to its own file, and introduce a non
  templatized base class.
- Cleanup the include hell.
- Sanitize the Node construction methods now that we
  got rid of that GenericNode/GenericGraph stuff.
- Protect against NodeId overflow in Graph.
- Various minor cleanups.

      Better typing and type verification · 0e16150d
      rossberg@chromium.org authored 
      - Extend verifier to check types of JS and Simplified nodes.
- Untyped nodes now contain NULL as types, enforcing hard failure.
- Typer immediately installs itself as a decorator; remove explicit decorator installation.
- Decorator eagerly types all nodes that have typed inputs
  (subsumes typing of constant cache, removing its typing
  side-channel and various spurious dependencies on the typer).
- Cut down typer interface to prevent inconsistently typed graphs.
- Remove verification from start, since it caused too much trouble
  with semi-wellformed nodes.
- Fix a couple of bugs on the way that got uncovered.

To do: verifying machine operators. Also, various conditions in the
verifier are currently commented out, because they don't yet hold.
