      [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] 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.

      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.
