git version: ba0763e4cb08015bd0acef5cf05a372d423017b4
system: ```Ubuntu 20.04.6 LTS (Focal Fossa)```
reproduced with: ```mlir-opt --lower-vector-mask a.mlir```
a.mlir:
```
func.func nested @func1() {
%cst_0 = arith.constant 4.102400e+04 : f16
%false = arith.constant false
%34 = vector.broadcast %cst_0 : f16 to vector<1xf16>
%35 = vector.broadcast %false : i1 to vector<1xi1>
%36 = vector.mask %35 { vector.multi_reduction <maxf>, %34, %34 [] : vector<1xf16> to vector<1xf16> } : vector<1xi1> -> vector<1xf16>
%40 = vector.extract_strided_slice %36 {offsets = [0], sizes = [1], strides = [1]} : vector<1xf16> to vector<1xf16>
vector.print %40 : vector<1xf16>
return
}
