Feature Name

Summary

Detailed Description

GCC 4.6.0 has been released on 2011-03-25. Fedora 15 has been rebuilt with it.

Benefit to Fedora

See http://gcc.gnu.org/gcc-4.6/changes.html for the list of changes.

Scope

All packages should be rebuilt with the new gcc once it hits dist-f15.

How To Test

GCC has its own testsuite, which is run during the package build, plus many other packages with automated tests also help to test the new gcc.

User Experience

Users will be able to see compiled code improvements and use the newly added features, such as improved C++0x support, support for the Go language, REAL*16 support in Fortran, etc.

Dependencies

All packages need to be rebuilt.

Contingency Plan

If bugs are discovered, I'd appreciate help from the package owners in preparing self-contained testcases to speed up analysis and fixing the bugs. Don't have time to debug issues in 8000+ packages, especially when in many cases it could be caused by undefined code in the packages etc. I don't expect we'll have to fall back to the older gcc.

Documentation

Release Notes

Fedora 15 comes with GCC 4.6.0 as primary compiler, see http://gcc.gnu.org/gcc-4.6/changes.html for user visible changes in it.
