Acovea Overview     ACOVEA (Analysis of Compiler Options via Evolutionary Algorithm) implements a genetic algorithm to find the "best" options for compiling programs with the GNU Compiler Collection (GCC) C and C++ compilers. "Best", in this context, is defined as those options that produce the fastest executable program from a given source code. Acovea is a C++ framework that can be extended to test other programming languages and non-GCC compilers. I envision Acovea as an optimization tool, similar in purpose to profiling. Traditional function-level profiling identifies the algorithms most influential in a program's performance; Acovea is then applied to those algorithms to find the compiler flags and options that generate the fastest code. Acovea is also useful for testing combinations of flags for pessimistic interactions, and for testing the reliability of the compiler.     http://www.coyotegulch.com/products/acovea/     tags: gcc g_ optimization Interactive Compilation Interface for GCC (GCC ICI)     http://gcc-ici.sourceforge.net/     tags: gcc g_ optimization Slashdot: News for nerds, stuff that matters     MI LEPOST GCC: machine learning based research compiler     http://gcc-ici.sourceforge.net/papers/fmtp2008.pdf     tags: gcc g_ optimization filetype_pdf media_document The LLVM Compiler Infrastructure Project     http://www.llvm.org/     tags: gcc c_ TalkChess.com :: View topic - Building Crafty 22.0 on a Maci...     hese compiler switches are probably quite far from optimal.
