**************************************************************** GCC-ICI v2.0 (Interactive Compilation Interface) The Interactive Compilation Interface (or 'ICI' for short) is a plugin system with a high-level compiler-independent and low-level compiler-dependent API to transform current compilers into collaborative open modular interactive toolsets. The ICI framework acts as a "middleware" interface between the compiler and the user-definable plugins. It opens up and reuses the production-quality compiler infrastructure to enable program analysis and instrumentation, fine-grain program optimizations, simple prototyping of new development and research ideas while avoiding building new compilation tools from scratch. For example, it is used in MILEPOST GCC to automate compiler and architecture design and program optimizations based on statistical analysis and machine learning. It should enable universal self-tuning compilers adaptable to heterogeneous, reconfigurable, multi-core architectures ranging from supercomputers to embedded systems. Currently ICI is a community-driven project to define common API to transform production-quality compilers with state-of-the-art transformations into collaborative modular plugin-enabled interactive R&D toolsets that allows quick prototyping of research ideas. In case the research idea becomes mature, it can now move to the mainline production compiler much faster. ICI can help end-users optimize their programs and architectures at fine-grain level to improve execution time, code size, power consumption, compilation time, etc. We also hope that using ICI will improve the quality and reproducibility of academic research. Eventually, we hope that it will help to overcome the complexity of current, emerging and future computing systems (including heterogeneous multi-core architectures) by simplifying and automating compiler design and testing as well as program optimization.

This helps to avoid writing research tools from scratch and utilize stable, production quality compilers. ICI can be used to enable research on iterative fine-grain program optimizations for different constraints (performance, code size, power consumption, DSE, different ISAs, etc), to unify optimization knowledge reuse among different programs and architectures using statistical and machine learning techniques, and to improve default compiler optimization heuristic. We hope that it will eventually make compilers truly modular with automatically tuned evolving optimization heuristics. More information: http://ctuning.org/wiki/index.php/CTools:ICI:Motivation **************************************************************** History: 2.0 - 20090529 - Major update, support for GCC 4.4.0, synchronization with GCC plugin branch, full documentation, community-based extension projects 1.0 - 20080613 - New version for MILEPOST GCC. ICI Plugins are separated from the distribution since they can be independent of GCC. Machine learning routines will be included in the MILEPOST GCC release. More info is available at http://unidapt.org/software.html#milepostgcc 0.9.6 - 20080312 - Updated version for the MILEPOST GCC (was not officially released). 0.9.5 - 20080211 - Updated design for correct pass selection and reordering avoiding pass-gate ... + some bug fixes. 0.9.1 - 20070916 - Bug fix release. 0.9 - 20070915 - New design using dynamically linked plugins and pass manipulations routines. 0.1 - 20070126 - Prototyping 0.0.1 - 20061103 - First prototype based on PathScale/Open64 ICI developed by Grigori Fursin in 2004. **************************************************************** Directories/files: gcc-4.4.0 - GCC 4.4.0 source directory (core + gfortran) src-third-party - Third party support tools | +-- gmp-4.3.0 - GMP library +-- mpfr-2.4.1 - MPFR library +-- ppl-0.10.2 - PPL library (for GRAPHITE) +-- cloog - CLOOG library (for GRAPHITE) +-- XSB - Prolog for machine learning tools (MILEPOST, UNIDAPT, cTuning) plugins-ici-2.0 - Plugins for GCC 4.4.0 ICI 2.0 (see README inside this directory) install - Directory with installed binaries **************************************************************** Installation: ./build_gcc.sh will build GCC with all the third-party tools. ./build_plugins.sh will build all plugins. Now you can test the plugin system using self-explanotary tests in plugins-ici-2.0/tests directory Full documentation is available here: http://ctuning.org/wiki/index.php/CTools:ICI:Documentation **************************************************************** Acknowledgments: * Fabio Arnone (STMicro, France) * Phil Barnard (ARC, UK) * Francois Bodin (CAPS Entreprise, France) * Zbigniew Chamski (InfraSoft IT Solutions, Poland) * Albert Cohen (INRIA, France) * Bjorn Franke (University of Edinburgh, UK) * Grigori Fursin (INRIA, France) * Taras Glek (Mozilla, USA) * Hugh Leather (University of Edinburgh, UK) * Cupertino Miranda (INRIA, France) * Mircea Namolaru (IBM, Israel) * Diego Novillo (Google, USA) * Sebastian Pop (AMD, USA) * Basile Starynkevitch (CEA, France) * Ayal Zaks (IBM, Israel) HiPEAC network of excellence (http://www.hipeac.net) Milepost project (http://www.milepost.eu) SARC project (http://www.sarc-ip.org) GGCC (http://www.ggcc.info) Other colleagues from IBM, NXP, STMicro, ARC, CAPS Enterprise ... **************************************************************** Future work: It's a community-driven project. You can find information about extensions at http://ctuning.org/ici Since 2009 we are working with GCC community to move parts of the ICI to the new GCC plugin branch. ****************************************************************
