These functions are only defined once in JSNodeDOMJIT.cpp & JSDocumentDOMJIT.cpp. And other ports just build it correctly.

And I also note that JSEventDOMJIT.cpp, JSElementDOMJIT.cpp and JSDocumentFragmentDOMJIT.cpp also have similar `checkSubClassPatchpoint` functions. But they do not cause linker errors according to the log. 1310391 5 fujii 2017-05-18 19:03:43 -0700 By checking with dumpbin, I've confirmed checkSubClassPatchpoint was exported from WebKit.dll. I'm guessing a following simple scenario. 1) JSDocumentDOMJIT.cpp was compiled with dllexport in WebCore 2) The linker included JSDocumentDOMJIT.cpp.obj into WebKit.dll 3) The linker found some dllexport-marked symbols in JSDocumentDOMJIT.cpp.obj and exported them from WebKit.dll I admit that this hypothesis doesn't explain comment 4. 1310493 6 pvollan 2017-05-18 23:39:16 -0700 Perhaps we shouldn't link with both WebKit.lib and WebCore.lib? In theory, I guess TestWebCoreLib only needs to link with WebCore.lib, and TestWebKitLib only needs to link with WebKit.lib. I would expect to get many other linker errors if this was the case, though. 1310515 7 ysuzuki 2017-05-19 01:34:55 -0700 (In reply to Fujii Hironori from comment #5) > By checking with dumpbin, I've confirmed checkSubClassPatchpoint was > exported from WebKit.dll. > I'm guessing a following simple scenario. > > 1) JSDocumentDOMJIT.cpp was compiled with dllexport in WebCore > 2) The linker included JSDocumentDOMJIT.cpp.obj into WebKit.dll > 3) The linker found some dllexport-marked symbols in > JSDocumentDOMJIT.cpp.obj and exported them from WebKit.dll > > I admit that this hypothesis doesn't explain comment 4. Right. I've just checked the generated JSNode.cpp in DerivedSoure. And I've found that, whole JSNode class is annotated by WEBCORE_EXPORT, while JSDocumentFragment is not. 1310517 8 310635 fujii 2017-05-19 01:50:16 -0700 Created attachment 310635 WIP patch (In reply to Per Arne Vollan from comment #6) > Perhaps we shouldn't link with both WebKit.lib and WebCore.lib?

Nice work!

I suggest soft linking the loadResourceIntoBuffer function. Yeah, that's great! In the meantime, I'll land the original patch by extracting checkSubClassPatchpoint from JSNode / JSDocument and move it to WebCore::checkSubClassPatchpointFor{JSNode,JSDocument}. 1310541 11 310639 fujii 2017-05-19 02:47:10 -0700 Created attachment 310639 Patch This is a layer violation and TestWebCore is just a unit test.
