I'm not able to build WebKitGTK 2.39.90 in i386 (the x86_64 build works fine): In file included from /tmp/webkit2gtk-2.39.90/Source/JavaScriptCore/llint/LowLevelInterpreter.cpp:432: JavaScriptCore/DerivedSources/LLIntAssembly.h: In static member function ‘static JSC::JSValue JSC::LLInt::CLoop::execute(JSC::OpcodeID, void*, JSC::VM*, JSC::ProtoCallFrame*, bool)’: JavaScriptCore/DerivedSources/LLIntAssembly.h:38532:23: error: ‘g_superSamplerCount’ was not declared in this scope 38532 | t1 = CAST<void*>(&g_superSamplerCount); // LowLevelInterpreter.asm:410 | ^~~~~~~~~~~~~~~~~~~ I didn't bisect this but it probably started with https://commits.webkit.org/260205@main
