Suppose on a non-pipelined single-processor machine, you have the following breakdown: alu instructions make up 25% of the dynamic instruction count, and take 2 cycles to execute.

Compilers and assemblers may be configured to sequence assembly language instructions in such a manner that a pipeline encounters the least amount of risk possible. One of the purposes of pipeline design is to achieve this. Do all assemblers and compilers rearrange assembly language instructions in the same manner in order to achieve the best potential degree of productivity?
