JSC mips/armv7 build seems to be broken. e.g.:https://build.webkit.org/builders/JSCOnly%20Linux%20ARMv7%20Thumb2%20Release/builds/11260/steps/compile-webkit/logs/stdio ../../Source/JavaScriptCore/dfg/DFGSpeculativeJIT32_64.cpp:2785:29: error: ‘class JSC::DFG::JITCompiler’ has no member named ‘isStrictModeFor’ callOperation(m_jit.isStrictModeFor(node->origin.semantic) ? operationPutByValWithThisStrict : operationPutByValWithThis, ^~~~~~~~~~~~~~~ In file included from ../../Source/JavaScriptCore/dfg/DFGJITCompiler.h:30, from ../../Source/JavaScriptCore/dfg/DFGSpeculativeJIT.h:34, from ../../Source/JavaScriptCore/dfg/DFGSpeculativeJIT32_64.cpp:28: MIPS: r259635 passed in https://build.webkit.org/builders/JSCOnly%20Linux%20MIPS32el%20Release/builds/4780 r259687 failed in https://build.webkit.org/builders/JSCOnly%20Linux%20MIPS32el%20Release/builds/4781 ARMv7: r259675 passed in https://build.webkit.org/builders/JSCOnly%20Linux%20ARMv7%20Thumb2%20Release/builds/11259 r259699 failed in https://build.webkit.org/builders/JSCOnly%20Linux%20ARMv7%20Thumb2%20Release/builds/11260 Regression range: r259675 - r259687
It's r259676. EWS also red for armv7/mips for corresponding bug https://bugs.webkit.org/show_bug.cgi?id=205578 with the same error: https://ews-build.webkit.org/#/builders/26/builds/13604
