; we can get fmin
define <4 x float> @getsmaxf32(<4 x float> %a, <4 x float> %b) {
entry:
%0 = fcmp nnan olt <4 x float> %a, %b
%1 = select nnan <4 x i1> %0, <4 x float> %a, <4 x float> %b
ret <4 x float> %1
}
; we can get fmax
define <4 x double> @getsmaxf64(<4 x double> %a, <4 x double> %b) {
entry:
%0 = fcmp nnan oge <4 x double> %a, %b
%1 = select nnan <4 x i1> %0, <4 x double> %a, <4 x double> %b
ret <4 x double> %1
}
```
The problem is about `olt` vs `oge`.
