Tuning compilations landscape

Performance is main key of all modern day applications and connotation of performance differs with the target platform and its intended application. Every component of software stack including the compiler tools needs to contribute towards achieving the better performance. The major hope and scope of further improvement through the highly matured and saturated domain of compiler optimization research is tuning compilations. Several researchers made significant contributions in this field over a period of time. In this paper the entire gamut of tuning compilation landscape is explored from various perspectives, like kind of problem being addressed, target platform, target objective and finally various tuning techniques been applied. This paper presents brief literature survey along with the trends in this important research area of compiler optimizations.
