I thought that's a question to us, perhaps I've asked it badly... I mean, do we
consider POWER10 instructions or only consider POWER9? From openpower-isa it
looks like it's POWER9; I've chosen POWER10 as present in "-mfuture", but I can
change it easily. Below are excerpts on how these -mpower10/-mfuture/-mlibresoc
look like in code (basically we're "-mfuture" with PPC_OPCODE_SVP64 flag).

  { "power10", (PPC_OPCODE_PPC | PPC_OPCODE_ISEL | PPC_OPCODE_64
                | PPC_OPCODE_POWER4 | PPC_OPCODE_POWER5 | PPC_OPCODE_POWER6
                | PPC_OPCODE_POWER7 | PPC_OPCODE_POWER8 | PPC_OPCODE_POWER9
                | PPC_OPCODE_POWER10 | PPC_OPCODE_ALTIVEC | PPC_OPCODE_VSX),
    0 },
  { "libresoc",  (PPC_OPCODE_PPC | PPC_OPCODE_ISEL | PPC_OPCODE_64
                | PPC_OPCODE_POWER4 | PPC_OPCODE_POWER5 | PPC_OPCODE_POWER6
                | PPC_OPCODE_POWER7 | PPC_OPCODE_POWER8 | PPC_OPCODE_POWER9
                | PPC_OPCODE_POWER10 | PPC_OPCODE_ALTIVEC | PPC_OPCODE_VSX
                | PPC_OPCODE_SVP64),
    0 },
  { "future",  (PPC_OPCODE_PPC | PPC_OPCODE_ISEL | PPC_OPCODE_64
                | PPC_OPCODE_POWER4 | PPC_OPCODE_POWER5 | PPC_OPCODE_POWER6
                | PPC_OPCODE_POWER7 | PPC_OPCODE_POWER8 | PPC_OPCODE_POWER9
                | PPC_OPCODE_POWER10 | PPC_OPCODE_ALTIVEC | PPC_OPCODE_VSX),
    0 },
