I mean

  ; NOTE: Assertions have been autogenerated by utils/update_llc_test_checks.py
  ; RUN: llc -mtriple=i686-unknown-linux-gnu -mattr=+bmi2 < %s | FileCheck %s --check-prefixes=X86
  ; RUN: llc -mtriple=x86_64-unknown-linux-gnu -mattr=+bmi2 < %s | FileCheck %s --check-prefixes=X64

Or

  ; NOTE: Assertions have been autogenerated by utils/update_llc_test_checks.py
  ; RUN: llc -mtriple=i686-unknown-linux-gnu < %s | FileCheck %s --check-prefixes=X86
  ; RUN: llc -mtriple=x86_64-unknown-linux-gnu < %s | FileCheck %s --check-prefixes=X64
