GCC: GNU Compiler Collection

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]

GHDL

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

GCC XML Node Introspector Project

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

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.

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.

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).

Making and using libraries

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

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]

Building and Testing gcc/glibc cross toolchains

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

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.

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.

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.

Writing a GCC Front End

By Tom Tromey. This article provides a tour of how you would go about connecting your own compiler front end to GCC.

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]

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]

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.
