What kind of DO-loop optimizations were there?
- Animats 10y agoThe same ones we have now. Advancing through an array with pointers instead of computing the subscript each time. Advancing down a higher dimension of an array with a stride. Backus had those working in a FORTRAN compiler in the 1950s. If FORTRAN had been slower than assembly, nobody would have used it; machines were too slow and too expensive.
