Looks like we need to extend a fix from other ports.

Comment on attachment 223541 [details] Patch EWS doesn't lie ... It broke the EFL build as the EWS noticed. I think the fno-maybe-uninitialized option was overwritten.
build log: /mnt/buildbot/efl-linux-slave-1/efl-linux-64-release-wk1/build/Source/JavaScriptCore/runtime/JSArray.cpp: In member function ‘void JSC::JSArray::copyToArguments(JSC::ExecState*, JSC::CallFrame*, uint32_t)’: /mnt/buildbot/efl-linux-slave-1/efl-linux-64-release-wk1/build/Source/JavaScriptCore/runtime/JSArray.cpp:1543:6: error: ‘value.JSC::JSValue::u.JSC::EncodedValueDescriptor::asInt64’ may be used uninitialized in this function [-Werror=uninitialized] /mnt/buildbot/efl-linux-slave-1/efl-linux-64-release-wk1/build/Source/JavaScriptCore/runtime/JSArray.cpp:1543:6: error: ‘value.JSC::JSValue::u.JSC::EncodedValueDescriptor::asInt64’ may be used uninitialized in this function [-Werror=uninitialized] cc1plus: all warnings being treated as errors The problem was caused by the -fno-tree-dce option. Unfortunately this error message isn't so useful because of inline functions. (line 1543 is the first line of the copyToArguments() function) I played a little bit with this function and it seems the problem is near here: https://trac.webkit.org/browser/trunk/Source/JavaScriptCore/runtime/JSArray.cpp#L1598 With commenting out this line, build works, so the build failure occured in this line. But unfortunately I have no idea how can it be uninitialized.

Okay. I reworked the patch to only apply to the GTK+ port. Thanks for the cleanup Ossy.
