--- Comment #1 from Hal Finkel <hfinkel at anl.gov> ---
This works on trunk:

$ echo '0x62 0xf2 0xf5 0x08 0xa9 0xc2' | llvm-mc -triple x86_64-unknown-unknown
-mcpu=knl -disassemble
    .text
    vfmadd213sd    %xmm2, %xmm1, %xmm0
$ echo '0x62 0xf2 0xf5 0x08 0xb9 0xc2' | llvm-mc -triple x86_64-unknown-unknown
-mcpu=knl -disassemble
    .text
    vfmadd231sd    %xmm2, %xmm1, %xmm0
$ echo '0x62 0xf2 0xf5 0x08 0x99 0xc2' | llvm-mc -triple x86_64-unknown-unknown
-mcpu=knl -disassemble
    .text
    vfmadd132sd    %xmm2, %xmm1, %xmm0
