[LLVMdev] VCOMISS instruction in X86

[Demikhovsky, Elena]

Hi,

I'm looking at scalar and packed instructions in X86.

  The instruction VCOMISS is scalar. May I remove SSEPackedSingle/SSEPackedDouble domain from it?


  defm VUCOMISS : sse12_ord_cmp<0x2E, FR32, X86cmp, f32, f32mem, loadf32,
                                  "ucomiss", SSEPackedSingle>, TB, VEX, VEX_LIG;
  defm VUCOMISD : sse12_ord_cmp<0x2E, FR64, X86cmp, f64, f64mem, loadf64,
                                  "ucomisd", SSEPackedDouble>, TB, OpSize, VEX,
                                  VEX_LIG;
  let Pattern = []<dag> in {
    defm VCOMISS  : sse12_ord_cmp<0x2F, VR128, undef, v4f32, f128mem, load,
                                    "comiss", SSEPackedSingle>, TB, VEX,
                                    VEX_LIG;
    defm VCOMISD  : sse12_ord_cmp<0x2F, VR128, undef, v2f64, f128mem, load,
                                    "comisd", SSEPackedDouble>, TB, OpSize, VEX,
                                    VEX_LIG;

Thanks.
