[PATCH] D145540: [InstCombine] Reduce absolute diff from min+max+sub

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added inline comments.


================
Comment at: llvm/test/Transforms/InstCombine/sub-minmax.ll:1035
+  %min = call i8 @llvm.smin.i8(i8 %b, i8 %a)
+  %max = call i8 @llvm.smax.i8(i8 %b, i8 %a)
+  %ab = sub nsw i8 %max, %min
----------------
shouldn't this be:
```
 %max = call i8 @llvm.smax.i8(i8 %a, i8 %b)
```
