Abstract
Because of the variety of the program behavior and different characteristics of the platforms, an optimizing compiler provides its users with options. To find out an effective combination of compiler options for the optimal program performance, the user must understand the program behavior, platform architecture, and the compiler options, which it is not easy for an average user. Systematic search methods have been proposed to find out effective combinations of compiler options, but these methods targeted user-space applications. This thesis proposes an improved search method. When applied on a kernel module, we achieved a 7% improvement over the GCC –O3, and our improved method saved 4% of search time over original search method.
