Appears to break linux-arm raspberry pi build. /usr/bin/ld: /home/martin/ws/jdk/build/linux-arm-server-release/hotspot/variant-server/libjvm/objs/foreign_globals.o: in function `ForeignGlobals::parse_call_regs(_jobject)': foreign_globals.cpp:(.text+0xb5c): undefined reference to `ForeignGlobals::parse_call_regs_impl(_jobject) const' /usr/bin/ld: /home/martin/ws/jdk/build/linux-arm-server-release/hotspot/variant-server/libjvm/objs/universalUpcallHandler.o: in function `PUH_SupportsOptimizedUpcalls': universalUpcallHandler.cpp:(.text+0xa0): undefined reference to `ProgrammableUpcallHandler::supports_optimized_upcalls()' /usr/bin/ld: /home/martin/ws/jdk/build/linux-arm-server-release/hotspot/variant-server/libjvm/objs/universalUpcallHandler.o: in function `PUH_AllocateOptimizedUpcallStub': universalUpcallHandler.cpp:(.text+0x1030): undefined reference to `ProgrammableUpcallHandler::generate_optimized_upcall_stub(_jobject, Method, _jobject, _jobject)' collect2: error: ld returned 1 exit status Looking for definitions of supports_optimized_upcalls ... I see only: ./src/hotspot/cpu/x86/universalUpcallHandler_x86_64.cpp ./src/hotspot/cpu/x86/universalUpcallHandler_x86_32.cpp ./src/hotspot/cpu/aarch64/universalUpcallHandler_aarch64.cpp so I expect the same failure on any architecture other than these 3.
