Looks good to me. (Stores are easier than loads)

  • Split functions in sve-masked-ldst-nonext.ll into separate load & store tests
  • Removed masked load tests from sve-masked-ldst-trunc.ll

Thanks for the changes to the tests.


I think it may be worth testing for z1.d explicitly and use CHECK-NEXT to make sure there are no other instructions that could do the truncation.

  • Improve CHECK lines used in sve-masked-ldst-nonext.ll & sve-masked-ldst-trunc.ll
