A Specialization Toolkit to Increase the Diversity of Operating Systems
... To support methodical specialization, we have been developing a toolkit that helps the kernel programmer in the tedious but important task of making specialized modules correct. For example, we have developed a specializer (called Tempo-C) [2, 1J for dynamic partial evaluation of C code, to simplify ...
