* For target hotspot_variant-server_libjvm_objs_c1_LIRAssembler_x86.o:
/pool/buildbot/slaves/sobornost/jdkX/build/src/hotspot/cpu/x86/c1_LIRAssembler_x86.cpp: In member function 'void LIR_Assembler::intrinsic_op(LIR_Code, LIR_Opr, LIR_Opr, LIR_Opr, LIR_Op*)':
/pool/buildbot/slaves/sobornost/jdkX/build/src/hotspot/cpu/x86/c1_LIRAssembler_x86.cpp:2399:11: error: enumeration value 'lir_none' not handled in switch [-Werror=switch]
     switch(code) {
           ^

The reported trouble is mishandled switch, but the actual reason is control flow problem with _LP64 disabled:

      case lir_abs :
        {
#ifdef _LP64
          if (UseAVX > 2 && !VM_Version::supports_avx512vl()) {
             ...
          } else { ; <----- this open brace should show up on !_LP64 path
#endif
         ...
          }
        }
