Authored by fpetrogalli on May 29 2020, 3:50 PM.



Adding intrinsics and codegen patterns for:

  • trn1 <Zd>.q, <Zm>.q, <Zn>.q
  • trn2 <Zd>.q, <Zm>.q, <Zn>.q
  • zip1 <Zd>.q, <Zm>.q, <Zn>.q
  • zip2 <Zd>.q, <Zm>.q, <Zn>.q
  • uzp1 <Zd>.q, <Zm>.q, <Zn>.q
  • uzp2 <Zd>.q, <Zm>.q, <Zn>.q

These instructions are defined in Armv8.6-A.

nit: I know this is unrelated to your changes, but the _128 suffix for these instruction names breaks convention in this file. While you're changing these lines, can you change it to _Q?

Replace _128 with _Q in the instruction definitions in tablegen.
