It is possible to teach compilers and assemblers to sequence assembly language instructions in a manner that poses the least possible danger to a pipeline. One of the purposes of a pipeline's layout is to achieve this. Do all assemblers and compilers rearrange assembly language instructions in the same manner to maximize efficiency?

Creating compilers and assemblers that reorder instructions in assembly language to reduce pipeline risks is one technique to improve their performance. I was wondering whether all assemblers and compilers optimized the same way when rearranging assembly language instructions.

Compilers and assemblers can rearrange assembler instructions to reduce pipeline risks as much as possible. What is the degree of consistency between how assemblers and compilers rearrange assembly language instructions?

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?
