Since the mid-1990s, researchers have been trying to use machine-learning-based
approaches to solve a number of different compiler optimization problems. These …

OpenCL has been designed to achieve functional portability across multi-core devices from
different vendors. However, the lack of a single cross-target optimizing compiler severely …

A large number of compiler optimizations are nowadays available to users. These
optimizations interact with each other and with the input code in several and complex ways …

Compiler flag selection can be an effective way to increase the quality of executable code
according to different code quality criteria. Evolutionary algorithms have been successfully …

Method invocation bytecodes are a fundamental aspect of class methods and object
interactions in object-oriented programming languages. However, their traditional …

Phase selection is the process of customizing the applied set of compiler optimization
phases for individual functions or programs to improve performance of generated code …

Due to the large number of optimizations provided in modern compilers and to compiler
optimization specific opportunities, a Design Space Exploration (DSE) is necessary to …

Modern software libraries and applications often need to be shared across environments
that do not always share common architectures. The solution to this code sharing has often …

This paper presents a new approach to efficiently search for suitable compiler pass
sequences, a challenge known as phase ordering. Our approach relies on information about …

Optimizing compilers rely on many hand-crafted heuristics to guide the optimization process.
However, the interactions between different optimizations makes their design a difficult task …
