Reveals efficient code generation via optimization, suggesting easier compiler retargeting.
This paper shows how thorough object code optimization has simplified a compiler and made it easy to retarget. The code generator forgoes case analysis and emits naive code that is improved by a retargetable object code optimizer. With this technique, cross-compilers have been built for seven machines, some in as few as three person days. These cross-compilers emit code comparable to hostspecific compilers.
