Until better optimizations are implemented, I see a "simple" optimization for vector ops. When the compiler knows an arrays are very small it unrolls the operation in-place: int n = 5; auto a = new int[n]; auto b = new int[n]; a[] += b[]; ==> int n = 5; auto a = new int[n]; // a and b are dynamic arrays, auto b = new int[n]; // but their length is easy to find at compile-time a[0] += b[0]; a[1] += b[1]; a[2] += b[2]; a[3] += b[4]; a[5] += b[5]; Bye, bearophile
