GCC 4.5 Status Update: Not Yet Branched
In early December we passed along a GCC 4.5 status update in which there were still 26 P1 regressions (the highest priority), 93 P2 regressions, and four P3 regressions. Red Hat's Jakub Jelinek has published a new GCC 4.5 status update on the GCC mailing list. As of today there are now only 18 regressions of P1 severity, 84 regressions of P2, and there's now nine P3 regressions.
Once those 18 P1 regressions are fixed, the first GCC 4.5 release candidate will be made, sometime hopefully in H1'2010. In semi-related news, GCC 4.4.3 was released this morning now that its regressions have been cleared.
For GCC 4.5 the MPC library has been integrated to evaluate complex arithmetic at compile time more accurately, a new link-time optimizer has been added, automatic parallelization can be enabled as part of Graphite, improved experimental support for C++0x, Windows improvements with Cygwin and MinGW, and many other changes that are documented on this web page.
