  • Targeted release: Releases/15
  • Last updated: (DATE)

[edit] Detailed Description

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

[edit] Benefit to Fedora

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

[edit] Scope

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

[edit] 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.

[edit] 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.

[edit] Dependencies

All packages need to be rebuilt.

[edit] 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.

[edit] Documentation

http://gcc.gnu.org/gcc-4.6/changes.html

[edit] 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.
