+    //
+    // I simplified the algorithm a little, so that it is a bit closer
+    // to the solution "v1" above.
+    //
+    // The major issue with "v1" is that we cannot load a full vector of bytes,
+    // because of the cast to ints. So we can only fill 1/4 of the maximal
+    // vector size. The trick here is to do an unrolling of factor 4, from:
+    //   h(i) = 31 * h(i-1) + a[i]
+    // to:
+    //   h(i+4) = h(i) * 31^4 + a[i + 1] * 31^3
+    //                        + a[i + 2] * 31^2
+    //                        + a[i + 3] * 31^1
+    //                        + a[i + 4] * 31^0
+    // The goal is now to compute this value for 4 bytes within a 4 byte
+    // lane of the vector. One concern is that we start with byte values,
+    // but need to do int-multiplication with powers of 31. If we instead
+    // did a byte-multiplication, we could get overflows that we would not
+    // have had in the int-multiplication.
+    // One trick that helps with chaning the size of the lanes from byte
+    // to short to int is doing all operations with unsigned integers. That
+    // way, we can zero-extend instead of sign-bit extend. The first step
+    // is thus to convert the bytes into unsigned values. Since byte is in
+    // range [-128..128), doing "a[i+j] + 128" makes it a positive value,
+    // allowing for unsigned multiplication.
+    // h(i+4) = h(i) * 31^4 +   a[i + 1]              * 31^3
+    //                      +   a[i + 2]              * 31^2

+ *  - Smaller vector size:

+ *  - Disable fill loop detection, so we don't use intrinsic but auto vectorization:
+ *      -XX:-OptimizeFill
+ *  - Lilliput can also have an effect, because it can change alignment and have

+    // I simplified the algorithm a little, so that it is a bit closer

+    // vector size. The trick here is to do an unrolling of factor 4, from:
+    //   h(i) = 31 * h(i-1) + a[i]
+    // to:
+    //   h(i+4) = h(i) * 31^4 + a[i + 1] * 31^3

+    //                        + a[i + 4] * 31^0
+    // The goal is now to compute this value for 4 bytes within a 4 byte
+    // lane of the vector. One concern is that we start with byte values,
+    // but need to do int-multiplication with powers of 31. If we instead
+    // did a byte-multiplication, we could get overflows that we would not
+    // have had in the int-multiplication.
+    // One trick that helps with chaning the size of the lanes from byte
+    // to short to int is doing all operations with unsigned integers. That
+    // way, we can zero-extend instead of sign-bit extend. The first step
+    // is thus to convert the bytes into unsigned values. Since byte is in
+    // range [-128..128), doing "a[i+j] + 128" makes it a positive value,
+    // allowing for unsigned multiplication.
+    // h(i+4) = h(i) * 31^4 +   a[i + 1]              * 31^3
