Description
$ java -XX:UseAVX=0 -version # To suppress the following error report, specify this argument # after -XX: or in .hotspotrc: SuppressErrorAt=/assembler_x86.cpp:1769 # # A fatal error has been detected by the Java Runtime Environment: # # Internal Error (src/cpu/x86/vm/assembler_x86.cpp:1769), pid=7986, tid=2 # assert(UseAVX) failed: # # JRE version: (9.0-b10) (build ) # Java VM: Java HotSpot(TM) 64-Bit Server VM (25.0-b62-fastdebug mixed mode solaris-amd64 compressed oops) On a machine which supports AVX we use vmovdqu() in generate_get_cpu_info(). We should use VM_Version::supports_avx() in the assert.
