================
Comment at: llvm/test/CodeGen/X86/fold-select.ll:4
 
 define <8 x float> @select_and_v8i1(<8 x i1> %a, <8 x i1> %b, <8 x i1> %c, <8 x float> %d) {
 ; CHECK-LABEL: select_and_v8i1:
----------------
I think passing vXi1 from arguments is not a common scenario. vXi1 will be promoted vXi16 during lowering arguments. You should add new test cases that generating vXi1 in the IR, e.g.:
```
%a = icmp eq <8 x i16> %0, %1
...
```
