Using Tracing and Dynamic Slicing to Tune Compilers

Technical Report #1174


Performance tuning improves a compiler's performance by detecting
errors and missed opportunities in its analysis, optimization, and
code generation stages. Normally, a compiler's author tunes it by
examining the generated code to find suboptimal code sequences. This
paper describes a collection of tools, called compiler auditors, that
assist a compiler writer by partially mechanizing the process of
finding suboptimal code sequences. Although these code sequences do
not always exhibit compiler bugs, they frequently illustrate problems
in a compiler. Experiments show that auditors effectively find
suboptimal code, even in a high-quality, commercial compiler.
