November 18, 2000
GCC now supports ISO C99 declarations in for loops (for (int i = 0; i < 10; i++) /* ... */). These are only supported in C99 mode (command line options -std=gnu99 or -std=c99), which will be the default in some future release, but not in GCC 3.0.
November 14, 2000
Michael Matz has donated an implementation of the Lengauer and Tarjan algorithm for computing dominators in the CFG. This algorithm can be significantly faster and more space efficient than our older algorithm. For one particularly nasty CFG from complex C++ code (more than 77000 basic blocks) compile time dropped from more than 40 minutes to around 25 minutes. Memory consumption was also dramatically decreased.
November 13, 2000
We have now switched the C++ front end to use libstdc++-v3, a new implementation of the ISO Standard C++ Library which brings significant changes and improvements over our ``old'' library. There still be may some rough edges, but we are addressing problems as soon as we learn about them -- please help testing and improving ``your'' ports!
November 13, 2000
GCC now supports two more ISO C99 features:
November 2, 2000
The C, C++ and Objective C front ends to GCC now use an integrated preprocessor by default. If all goes well, this will also be the default mode for GCC 3.0.
November 1, 2000
Support for C99's _Pragma operator has been added to the preprocessor. This feature effectively makes it possible to have #pragma directives be part of macro expansions, and to have their arguments expanded too if necessary.
October 6, 2000
We would like to point out that GCC 2.96 is not a formal GCC release nor will there ever be such a release. Rather, GCC 2.96 has been the code- name for our development branch that will eventually become GCC 3.0. More...
Sep 11, 2000
Zack Weinberg of Cygnus, a Red Hat company, has contributed modifications to the C, C++, and Objective C compilers which permit them to use the C preprocessor library (cpplib) directly instead of via a separate executable.

This is not yet the default mode, but we hope it will be the default in GCC 3.0. When it is used the compiler will be faster because it will not have to do lexical analysis twice, nor save the preprocessed output to a temporary file. In the future, this will permit better error messages, and more detailed debugging information particularly when complex macros are used.

Sep 11, 2000
Neil Booth has contributed a new lexer and macro-expander for the C preprocessor. The lexer makes a single pass over the source files, whereas previously it made two. The macro expander operates on lexical tokens instead of text strings.

ISO C, C++, and Objective C use the new preprocessor. Traditional (K+R) C, Fortran, and Chill use an older implementation (taken from GCC 1) which obeys the rules for pre-standard C preprocessing. Either version may be used to preprocess assembly language.

May 2, 2000

Stan Cox and Jason Eckhardt of Cygnus, a Red Hat company, have contributed a basic block reordering pass. The optimization can reposition basic blocks from across the entire function in an attempt to reduce branch penalties and enhance instruction cache efficiency.

Our thanks go to Michael Hayes, Jan Hubicka, and Graham Stott who noticed or fixed defects or made other useful suggestions.

May 1, 2000

Richard Earnshaw of ARM Ltd, and Nick Clifton of Cygnus, a Red Hat company, have contributed a new backend for the Arm and Thumb processors.

The new backend combines code generation for the Arm, the Thumb and the StrongArm into one compiler, with the target processor and instruction sets being selectable via command line switches.

April 30, 2000
Michael Meissner and Nick Clifton of Cygnus, a Red Hat company, have contributed a port for the Mitsubishi D30V processor.

Michael Meissner and Richard Henderson of Cygnus, a Red Hat company, have contributed a new if-conversion pass. The code runs faster and identifies more optimization opportunities than the old code. In addition, it also has support for conditional (predicated) execution, such as is found in the Intel IA-64 architecture, the ARM processors, and numerous embedded LIW and DSP parts.

March 22, 2000
The Steering Committee has appointed Mark Mitchell, of CodeSourcery, LLC, to manage the GCC 3.0 release and as a new Steering Committee member. CodeSourcery will be providing time from Mark, Alex Samuel, and other personnel, to manage the release. Thanks!

Probably the most important decision reached at the meeting is that Craig Burley will undertake the long-awaited 0.6 rewrite of the g77 front end as his top priority for the gcc 3.0 release, rather than focusing on implementing some of the most wanted features that didn't require the rewrite, such as Cray pointers.
The BOF provided us with some additional information to guide future development of GNU Fortran. Thanks to all who attended, whether in person or in spirit!
May 18, 1999
The sixth snapshot of the ongoing re-written C++ Standard Library has been released. It includes SGI STL 3.2, an automatically generated <limits>, a partially re-written valarray, a working stringbuf and stringstream (for basic types). For more information, please check libstdc++ home page.
April 23, 1999
