JavaScriptCore: Simplified the host calling convention.

Reviewed by Sam Weinig, Gavin Barraclough, Oliver Hunt.

22.5% speedup on 32-bit host function calls. 9.5% speedup on 64-bit host
function calls.

No change on SunSpider.

All JS calls (but not constructs, yet) now go through the normal JS
calling convention via the RegisterFile. As a result, the host calling
convention, which used to be this

JSValue (JSC_HOST_CALL *NativeFunction)(ExecState*, JSObject*, JSValue thisValue, const ArgList&)


is now this

JSValue (JSC_HOST_CALL *NativeFunction)(ExecState*)


Callee, 'this', and argument access all hapen relative to the ExecState*,
which is a pointer into the RegisterFile.

This patch comes in two parts.

PART ONE: Functional code changes.

  • wtf/Platform.h: Disabled optimized calls on platforms I didn't test.

We can re-enable once we verify that host calls on these platforms are
correct.

  • debugger/DebuggerCallFrame.cpp:

(JSC::DebuggerCallFrame::functionName):
(JSC::DebuggerCallFrame::calculatedFunctionName): Updated for change to
ExecState::callee().

(JSC::DebuggerCallFrame::thisObject): Updated for removal of ExecState::thisValue().

  • interpreter/CallFrame.cpp:
  • interpreter/CallFrame.h:

(JSC::ExecState::callee):
(JSC::ExecState::scopeChain):
(JSC::ExecState::init): Changed callee() to be JSObject* instead of
JSFunction* -- now, it might be some other callable host object.

(JSC::ExecState::hostThisRegister):
(JSC::ExecState::hostThisValue):
(JSC::ExecState::argumentCount):
(JSC::ExecState::argumentCountIncludingThis):
(JSC::ExecState::argument):
(JSC::ExecState::setArgumentCountIncludingThis):
(JSC::ExecState::setCallee): Added convenient accessors for arguments
from within a host function. Removed thisValue() because it was too
tempting to use incorrectly, and it only had one or two clients, anyway.

  • interpreter/Interpreter.cpp:

(JSC::Interpreter::callEval): Updated for removal of ExecState::thisValue().

(JSC::Interpreter::throwException): Be sure to shrink the register file
before invoking the exception handler, to reduce the chances that the
handler will re-throw in the case of stack overflow. (Re-throwing is now
more likely than it used to be, since standardizing the calling convention
implicitly added stack overflow checks to some places where they used to be missing.)

(JSC::Interpreter::execute): Clarified the scope of DynamicGlobalObjectScope.
Updated for CallFrame::init API change.

(JSC::Interpreter::executeCall): Clarified scope of DynamicGlobalObjectScope.
Updated for CallFrame::init API change. Added support for calling a host
function.

(JSC::Interpreter::executeConstruct): Clarified scope of DynamicGlobalObjectScope.
Updated for CallFrame::init API change.

(JSC::Interpreter::prepareForRepeatCall): Updated for CallFrame::init API change.

(JSC::Interpreter::privateExecute): Updated for CallFrame::init API change.
Added some explicit JSValue(JSObject*) initialization, since relaxing
the JSFunction* restriction on callee has made register types more ambiguous.
Removed toThisObject() conversion, since all callees do it themselves now.
Updated host function call for new host function signature. Updated for
change to ExecState::argumentCount() API.

  • interpreter/Register.h:

(JSC::Register::):
(JSC::Register::operator=):
(JSC::Register::function): Changed callee() to be JSObject* instead of
JSFunction* -- now, it might be some other callable host object.

  • jit/JITOpcodes.cpp:

(JSC::JIT::privateCompileCTINativeCall):

  • jit/JITOpcodes32_64.cpp:

(JSC::JIT::privateCompileCTINativeCall): Deleted a bunch of code that
set up the arguments to host functions -- all but one of the arguments
are gone now. This is the actual optimization.

  • jit/JITStubs.cpp:

(JSC::DEFINE_STUB_FUNCTION): Updated for ExecState and Register API
changes noted above. Removed toThisObject() conversion, since all callees
do it themselves now.

  • runtime/ArgList.h:

(JSC::ArgList::ArgList): ArgList is getting close to unused. Added a
temporary shim for converting from ExecState* to ArgList where it's still
necessary.

  • runtime/Arguments.h:

(JSC::Arguments::getArgumentsData):
(JSC::Arguments::Arguments): Updated for ExecState and Register API
changes noted above.

  • runtime/CallData.cpp:

(JSC::call): Changed call always to call Interpreter::executeCall, even
for host functions. This ensures that the normal calling convention is
set up in the RegsiterFile when calling from C++ to host function.

  • runtime/CallData.h: Changed host function signature as described above.
  • runtime/ConstructData.cpp:

(JSC::construct): Moved JSFunction::construct code here so I could nix
JSFunction::call and JSFunction::call. We want a JSFunction-agnostic
way to call and construct, so that everything works naturally for non-
JSFunction objects.

  • runtime/JSFunction.cpp:

(JSC::callHostFunctionAsConstructor):

  • runtime/JSFunction.h: Updated for ExecState and Register API changes

noted above. Nixed JSFunction::call and JSFunction::construct, noted above.

  • runtime/JSGlobalObject.cpp:

(JSC::JSGlobalObject::init): Ditto.

PART TWO: Global search and replace.

In the areas below, I used global search-and-replace to change

(ExecState*, JSObject*, JSValue, const ArgList&) => (ExecState*)
args.size() => exec->argumentCount()
args.at(i) => exec->argument(i)

Changed these results to expect to fail to stringify their exception
objects in the case of stack overflow. (Standardizing the calling
convention has implicitly added stack overflow checks to some places
where they used to be missing.)

In a future patch, I plan to implement a more reliable way to stringify
exceptions without invoking a JS function. For now, though, it seems best
to match other test results, instead of silently overflowing the stack.
