I think it is overkill. Apart from rather silly microbenchmarks, there
isn't much point in adding the loop unrolling facility. In real world,
even cheap operations such as "x = x + 1" will be surrounded by less
cheap operations, so if an improvement cannot yield tangible benefits
inside a simple for loop, then it doesn't deserve to be committed. |
