The old code did not work correctly in case of optimizations. I
found this out when implementing concise methods and we now plumb
through the function kind so we know what kind of Map to create for
the function.

Reland · 4ec63ff9

sigurds@chromium.org authored Sep 12, 2014

- "Switch inlining to use simplified instead of machine loads."
- "Add copy support in inliner."

Reland fixes:
 - size_t conversion for 64bit arches
 - Don't call front() on empty vector
   (triggers assertion on windows)
 - turbo_inlining now implies turbo_types, as
   it requires simplified lowering.

X87: Added CallInterfaceDescriptors to all code stubs. · 0ada8cfe

weiliang.lin@intel.com authored Sep 12, 2014

port r23854.

original commit message:

  Added CallInterfaceDescriptors to all code stubs. A handful
  of code stubs are too complex to be described this way, and
  they are encoded with the macro
  DEFINE_NULL_CALL_INTERFACE_DESCRIPTOR().

  Along the way:
  * allowed inheritance of CallInterfaceDescriptors.
  * Defined static Register methods for some of the new
    CallInterfaceDescriptors. We could go a lot further here, but
    it doesn't have to be done immediately.
  * Added Representation arrays to some CallInterfaceDescriptors,
    especially where future hydrogen versions of the stubs could
    benefit from this knowledge.
