Release Notes: This release fixes over 100 reported problems.
Release Notes: This is a bug-fix release containing fixes for regressions and serious bugs, with over 150 bugs fixed since the previous release.
Release Notes: Support for several processor architectures was obsoleted, while new platforms were added. A new general optimization level, -Ofast, was introduced. The Scalable Whole Program Optimizer (WHOPR) project has stabilized to the point of being usable. Many link-time and interprocedural optimization improvements were made. In the C family of languages, support for selectively enabling and disabling warnings was added. The experimental support for C++0x was improved, as well as for the C1X revision of the ISO C standard. Many C++ diagnostics were improved. Many other improvements were made.
Release Notes: The new link-time optimizer LTO ("-flto") is now also supported on several non-ELF targets, namely Cygwin (*-cygwin*), MinGW (*-mingw*), and Darwin on x86-64 (x86_64-apple-darwin*), though LTO is not enabled by default for these targets. Numerous minor bugs were fixed.
Release Notes: Optimizations for Intel Atom processors were added, and the support for other processors was enhanced. The MPC library was integrated for more accurate compile time arithmetic evaluation. A new link-time optimizer was added, to allow for inter-procedural optimizations. Many optimizations were improved. The C compilers now exit immediately on a missing header file. The experimental support for C++0x was improved. An experimental C++ profile mode was added. Many other changes were made.
Release Notes: This is the 3rd bug fix release for GCC 4.4.
Release Notes: This release fixes a number of regressions and other bugs.
Release Notes: Many optimizer improvements were made. Version 3.0 of the OpenMP specification is now supported for the C, C++, and Fortran compilers. "Uninitialized" warnings do not require enabling optimization anymore. The experimental support for the upcoming ISO C++ standard C++0x was improved. Several new targets and target specific improvements were introduced, while several old targets were obsoleted or removed. Many bugs were fixed.
Release Notes: This release contains fixes for regressions in GCC 4.3.2 relative to previous releases of GCC.
