(to remove the test of m_fiberCount in isRope) Still, that's a separate question really. After this patch, will we ever be creating RopeImpls? Should this patch not be removing RopeImpl.cpp/.h from svn? r+, but I think you should probably be using jsNontrivialString in the case I point out, and probably remove the RopeImpl files. > Source/JavaScriptCore/runtime/JSValue.cpp:222 > + return JSString::create(exec->globalData(), UString("undefined").impl()); Maybe we should have an JSString::create(ExecState*, const char*) helper? - Actually, I think we have one! - this should call: inline JSString* jsNontrivialString(JSGlobalData* globalData, const char* s) > Source/JavaScriptCore/runtime/Operations.h:96 > ALWAYS_INLINE JSValue jsString(ExecState* exec, JSValue thisValue) This method is really poorly named (my bad, I believe :-( ) - there is nothing in the name indicating it does anything to do with arguments, we should really rename it to something more explicit. > Source/JavaScriptCore/runtime/SmallStrings.cpp:109 > + m_emptyString = JSString::createHasOtherOwner(*globalData, UString("").impl()); This could be 'StringImpl::empty()' > Source/JavaScriptCore/runtime/StringPrototype.cpp:640 > + : jsString(exec, asString(thisValue), JSString::create(exec->globalData(), v.toString(exec).impl()))); We create JSStrings with arguments like this in quite a few places, maybe we should have an JSString::create(ExecState*, JSValue)? 486516 3 ggaren 2011-10-18 19:02:03 -0700 > > Source/JavaScriptCore/runtime/JSValue.cpp:222 > > + return JSString::create(exec->globalData(), UString("undefined").impl()); > > Maybe we should have an JSString::create(ExecState*, const char*) helper? - > Actually, I think we have one! - this should call: > > inline JSString* jsNontrivialString(JSGlobalData* globalData, const char* s) Ah yes. Actually, all of my direct calls to JSString::create are broken on Windows, since they miss the glorious call to fixupVPtr. I'll fix those, and fix the rest in a follow-up patch. 486528 4 ggaren 2011-10-18 19:53:28 -0700 Committed r97827: <http://trac.webkit.org/changeset/97827> 111507 2011-10-18 14:48:41 -0700 2011-10-18
