If JIT is disabled, or -DUSE_64KB_PAGE_BLOCK=ON is used, then the build fails on aarch64: /usr/lib64/gcc/aarch64-suse-linux/13/../../../../aarch64-suse-linux/bin/ld: Source/JavaScriptCore/CMakeFiles/JavaScriptCore.dir/__/__/JavaScriptCore/DerivedSources/unified-sources/UnifiedSource-15db4ad9-3.cpp.o: in function `void* JSC::machineCodeCopy<WTF::ConstexprOptionSet<JSC::RepatchingFlag>{}>(void*, void const*, unsigned long)': /home/abuild/rpmbuild/BUILD/webkitgtk-2.51.90/build/JavaScriptCore/PrivateHeaders/JavaScriptCore/AssemblerCommon.h:635:(.text._ZN3JSC14ARM64Assembler16relinkJumpOrCallILNS0_10BranchTypeE0EEEvPiPKiPv[_ZN3JSC14ARM64Assembler16relinkJumpOrCallILNS0_10BranchTypeE0EEEvPiPKiPv]+0xb8): undefined reference to `void* JSC::performJITMemcpy<WTF::ConstexprOptionSet<JSC::RepatchingFlag>{}>(void*, void const*, unsigned long)'
