 Application optimization with compilers for Linux

Interested in tuning your C/C++ applications for Linux on POWER? This article compares the optimization options for both Linux on POWER C/C++ compilers: GCC and IBM XL C/C++. This paper also reviews tactics, such as Interprocedural Analysis, Profile Directed Feedback, and High Order Transformations, which are used by one or both of the compilers to extract higher performance from the Power architecture.
