Launchpad Entry: https://launchpad.net/distros/ubuntu/+spec/edgy-toolchain-roadmap
Created: 2006-06-09 by MatthiasKlose
Packages affected: gcc*, gcj*, glibc, binutils
- Name the versions of affected packages targeted for edgy.
- Multiarch integration not a hard goal for edgy, may be postponed for edgy+1.
- Updates for the biarch setup.
- Drop obsolete compiler packages
Edgy has a short release cycle, so we will use edgy as a testbed for one major change (stack protection), but keep the rest of the toolchain rather un-edgy and use the time to prepare a solid work for edgy+1 (EdgyPlusOneToolchainRoadmap).
- NPTL is enabled and the default in glibc-2.4, linuxthreads not enabled anymore
- all release architectures and ia64 supported
- upstream tools
- glibc-2.4, in edgy.
- binutils-2.17, needs testing and packaging, not yet available in unstable.
- gcc-4.1.1, gcc-4.1.2 likely after edgy freeze; follow the 4.1 branch to some point, then apply patches for wrong-code/ice-on-valid failures.
Optional/time available items
- multiarch/biarch related changes
- no multiarch changes explicitely targeted for edgy, see if glibc, gcc, binutils can be changed to transparently install in multiarch locations.
- biarch -m32/-m64 changes (See as well outstanding issues / discussion below)
- on sparc, build a sparc64-linux (host) to sparc-linux/sparc64-linux compiler (target) defaulting to sparc-linux by default (requested by the sparc port).
for i386, build a non-biarch compiler, plus a i386->amd64 cross compiler, which still can be called using gcc -m64.
provide <triplet>-<tool> wrappers for the biarch compilers.
- Demoting compilers to universe, which are not necessarily needed for main
- gcc-3.3 based compilers
- gcc-4.0 based compilers (although g++-4.0 may be needeed for regressions found in g++-4.1)
- NPTL on hppa: certainly broken, hppa is a community arch, no explicit action is taken; maybe same situation with db4.3 on hppa dapper.
