Indirect Jumps Improve Instruction Sequence Performance

Instruction sequences with direct and indirect jump instructions are as expressive as instruction sequences with direct jump instructions only. The authors show that, in the case where the number of instructions is not bounded, there exist instruction sequences of the former kind from which elimination of indirect jump instructions is possible without a super-linear increase of their maximal internal delay on execution only at the cost of a super-linear increase of their length. They take the view that sequential programs are in essence sequences of instructions.
