@banach-space  hey i have a question so i was importing the test cases from  lang/test/CodeGen/AArch64/neon-intrinsics.c, but for some reason i am unable to fill the check-lines using update_cc_test_checks.py, am i missing something ? 

// LLVM-LABEL: @test_vqshlud_n_s64
// CIR-LABEL: @vqshlud_n_s64
int64_t test_vqshlud_n_s64(int64_t a) {

  return (int64_t)vqshlud_n_s64(a, 1);
}

// LLVM-LABEL: @test_vqshld_n_s64
// CIR-LABEL: @vqshld_n_s64
int64_t test_vqshld_n_s64(int64_t a) {

  return vqshld_n_s64(a, 1);
}
