GNU Compiler Collection resources

Developed by GNU project as free compiler for GNU system. Front ends: C, C++, Objective-C, Fortran, Java, Ada; libraries for libstdc++, and libgcj. Mission, mail lists, timeline, contributors, committee, instructions, manual, FAQ, downloads, plans, bug reports. [Open Source, GPL]

Building and Testing gcc/glibc cross toolchains

Script to automatically download, patch, build, and test binutils, gcc, and glibc cross-toolchains.

D Front End for GCC

For GCC 3.3.x, 3.4.x versions supporting FreeBSD, Linux, Mac OS X, Cygwin. Description, build instructions, downloads, links, contact. [Open source]

DaLSoft

Optimizer for gcc generated x86 code. Lists results of optimizations, compares performance of the optimizer-generated code with performance of the code generated by gcc and icc x86 compilers.

Distcc

A gcc wrapper that speeds compilation by transparently distributing work across several machines. [Open source, GPL]

EGCS: Experimental GNU Compiler System

Project fused work on GNU C, C++, Objective-C, Ada, Fortran compilers, and libc++, to speed up work to improve GCC. In April 1999 was merged into general GCC effort under control of GCC steering committee. Descriptions, a few links.

GCC XML Node Introspector Project

Project to create an XML interface to the GCC AST tree_nodes and store in Postgres Database.

GHDL

A written in Ada95 GCC front-end. It is a VHDL simulator and implements nearly all VHDL87 and some features of VHDL93.

GNU C Compiler Internals Wikibook

This is a wikibook describing internals of GNU C Compiler Collection. A number of authors have contributed to it.

GNU Objective-C runtime features

Some notes about garbage collection and type information strings in the GNU Objective-C runtime (2.95.3 GCC version).

GNUDE: GNU Development Environment

Suite of GNU C/C++, Fortran, Java cross compilers, and Insight/GDB debugger hosted on Windows NT/2K/XP for embedded ARM7/9, XScale CPU program development. Assembler, compilers, linker, header files, STL, libraries, documents.

Making and using libraries

Guide work with libraries (.a files) in g++.

Migrating to gcc-3.4

A collection of migration guides to help programmers updating their code to be gcc-3.4 compatible.

Pinapa

An open source SystemC front-end. It relies on GCC to parse the C++, and on the SystemC library itself to extract the architecture of the platform to analyze.

PL/1 for GCC

A PL/1 front-end for GNU Compiler Collection. It based on the syntax from IBM OS PL/I Version 2.

By Tom Tromey. This article provides a tour of how you would go about connecting your own compiler front end to GCC. (April 06, 2005)

Optimization in GCC

By M. Tim Jones. Here's what the O options mean in GCC, why some optimizations aren't optimal after all and how you can make specialized optimization choices for your application. [Linux Journal] (January 26, 2005)

LWN: GCC gets a new Optimizer Framework

Artciel by Steven Bosscher and Diego Novillo. The first bits a major compiler internals overhaul have been merged into the development mainline of the GNU Compiler Collection (GCC) for inclusion in the next release. (May 12, 2004)

Optimizing GCC

How much faster can GCC compile a Linux kernel if GCC is optimized? Doing the compiler alone ups speed 33%. Description, benchmark times. [Linux Gazette] (March 01, 2003)

GCC Myths and Facts

Optimizing GCC mostly for x86 CPU and C/C++, but parts can apply to all supported CPUs and languages. Many useful forum comments. [Freecode] (February 15, 2003)
