            Bug ID: 3392460
           Summary: Use of VAESENC, VAESDEC, VAESENCLAST, VAESDECLAST,
                    VPCLUMQUDQ produce assemble error
           Product: NASM
           Version: 2.13.xx
          Hardware: All
                OS: All
            Status: OPEN
          Severity: critical
          Priority: Medium
         Component: Assembler
          Assignee: nobody at nasm.us
          Reporter: tomasz.kantecki at intel.com
                CC: gorcunov at gmail.com, hpa at zytor.com, nasm-bugs at nasm.us
     Obtained from: Built from git using configure

Version in which detected:
    nasm-2.13rc5

Instructions used to reproduce:
    "vpclmulqdq zmm0, zmm1, zmm2, 0"
    "vaesenc    zmm0, zmm1, zmm2"
    "vaesenclast zmm0. zmm1, zmm2"

Error message:
    "error: invalid combination of opcode and operands"

Note:
    From quick inspection of the x86/insns.dat file it seems that definitions
of the new instructions are not there in rc5.
    Original bugs for adding the instructions:
        https://bugzilla.nasm.us/show_bug.cgi?id=3392454
        https://bugzilla.nasm.us/show_bug.cgi?id=3392455

    The instructions seem to be merged on branch nasm-2.13.xx but they cannot
be found on nasm-2.13rc5.
    Tip of nasm-2.13.xx produces a different error for the instructions though:
    "error: no instruction for this cpu level"
