This release is a major > upgrade to the compilers, with a particular focus on the performance > of the generated code. The developers have measured performance > improvements of 5% to 10% on high-performance computing benchmarks. > (Of course, results vary depending on choice of CPU, benchmark, and > optimization options.) > > GCC 4.5.0 is now capable of "link-time optimization". Traditionally, > most C and C++ compilers (including GCC) have only been able to > optimize within a single source file or "module". GCC was therefore > unable to take advantage of optimization opportunities that required > knowledge about multiple modules. This limitation has been removed in > GCC 4.5.0. This optimization can provide significant increases in > performance and equally significant reductions in code size. > > In addition, GCC 4.5.0 has improved loop optimization infrastructure. > This infrastructure, based on an advanced "polyhedral" model for > optimization, allows GCC to perform more advanced loop optimizations. > In the future, this infrastructure will be tuned and used more heavily. > > GCC 4.5.0 also features improvements for a wide variety of specific > architectures, including support for recent CPUs using the ARM, AVR, > ColdFire, MIPS, Power, SuperH, and x86 architectures. GCC also > generates better debug information for optimized code, including > information about the value of variables that have been optimized > away. And, of course, a wide variety of defects in all parts of the > compiler (ranging from language conformance to code-generation) have > been corrected. > > Refer to gcc.gnu.org: > > http://gcc.gnu.org/gcc-4.5/changes.html > > for more information about this release. > > GCC 4.5.1, with corrections for any critical defects reported in GCC > 4.5.0, is expected in July, 2010. > > As always, a vast number of people contributed to this GCC release -- > far too many to thank individually! > > -- > Mark Mitchell > CodeSourcery > [email protected] > (650) 331-3385 x713 > -- Andy Lester => [email protected] => www.theworkinggeek.com => AIM:petdance _______________________________________________ http://lists.parrot.org/mailman/listinfo/parrot-dev
