Looks like this do not work:

// Type your code here, or load an example. int a[10]; void unswitch2(int i, int x, int y0, int y1) { if (x) { a[i] = y0; a[i + 1] = y1; } else { a[i + 1] = y0; a[i] = y1; } }

Interestingly, only icc produces the same code for both forms in this case. https://godbolt.org/g/Go7Hoo I'm not entirely convinced this matters, but if you care, consider opening a bug on llvm.org/bugs and/or submitting a patch.
