Nevermind. Found the answer myself:

+#if[longOrDouble64]
+        // We use a 64-bit int vector since there are no Int32 types.
+        // We will broadcast the first value through the vector.
+        Vector.Shape shape = Vector.shapeForVectorBitSize(64);
+#else[longOrDouble64]
...
+       // Load index map into a vector
+#if[longOrDouble64]
+        IntVector<Vector.Shape> vecInd = intSpec.broadcast(b[iy]);
+#else[longOrDouble64]
