Packages affected: gcc*, gcj*, glibc, binutils
Summary
tfheen: general comment: please use full sentences and be a bit more verbose.
- Versions targeted.
tfheen: Which versions?
- Multiarch integration / biarch updates
tfheen: Change to "Multiarch integration postponed" or something along those lines?
- Defaults for Stack Protection
tfheen: "Enable stack protection by default"
- Drop obsolete compiler packages
Separate specs are GccSsp and JavaRoadmap.
Rationale
Edgy has a short release cycle, use edgy as a testbed for one major change, but keep the rest of the toolchain rather un-edgy and use the time to prepare a solid work for edgy+1 (EdgyPlusOneToolchainRoadmap).
tfheen: a bit more verbosity would be good.
Implementation
- NPTL is enabled and the default in glibc-2.4, linuxthreads not enabled anymore
- all release architectures and ia64 supported
- hppa certainly broken
tfheen: What's the plan for fixing hppa?
details can be found in GccSsp
tfheen: details for what; please reword?
turn on -fstack-protector and see what happens (pending approval in GccSsp).
- prepare a more solid solution for edgy+1
- provide some kind of documentation / tutorial; not much included upstream
- Add libssp0-dev as a dependency of gcc-4.1, or merge it into gcc-4.1.
- 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-gnu compiler defaulting to sparc-linux-gnu by default (requested by the sparc port).
tfheen: is a sparc64-linux-gnu compiler a compiler whose host is sparc64-linux-gnu or whose target is sparc64-linux-gnu ?
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 (See outstanding issues).
tfheen: outstanding issues is empty.
- 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.
