Looking at the overlap of the FC4 schedule with the GCC 4.0 schedule, it appears that shipping GCC 4.0 in FC4 has become viable. In order to avoid a large duplication of bandwidth by rebuilding with GCC 4.0 between test releases, Fedora Core 4 Test 1 has now slipped two weeks to allow for integration of a GCC 4.0 snapshot, and rebuilds against it. Fedora Core 4 Test 1 is now scheduled for March 14; the schedule at http://fedora.redhat.com/participate/schedule/ will be updated shortly. Quick FAQs: - Is GCC 4.0 released yet? No. It's likely to be released around mid-April. - Does that mean Fedora Core 4 will ship with a pre-release compiler? We're not *that* crazy. If GCC 4.0 is delayed, we will either revert, or slip. - What's so cool about GCC 4.0? GCC 4.0 includes: - new intermediate languages that allow for new/better optimizations http://gcc.gnu.org/projects/tree-ssa/ As part of this, this allows for better compile and run-time memory checking and overflow protection. - better and more complete Java support - Fortran 95 support - Is GCC 4.0 ABI compatbile with GCC-3.4.x? - For C/C++, yes.
