Summary

Plans for the toolchain to be ready when Edgy+1 opens the archives

• Have a tested toolchain ready for edgy+1
• ABI changes/change of default options
• Upstream versions

• Interaction with gcc-ssp spec (https://launchpad.net/distros/ubuntu/+spec/gcc-ssp)

• Implement changes deferred from EdgyToolchainRoadmap.

Rationale

Use cases

Scope

Implementation

• testing: Rebuild a current edgy archive using the proposed toolchain for edgy+1 for all release architectures; requires LP/Soyuz support.
• powerpc/sparc: glibc/gcc: configure using --enable-long-double-128
• Upstream versions
  • glibc-2.4.x
  • binutils-2.17.x
  • gcc-4.2.x
    • tune with -mtune=generic by default
  • gcj-4.2.x, follow the development of the ecj branch for 1.5 language and runtime features

Code

Data preservation and migration

Outstanding issues

• removal of compilers for additional languages that should not
  • be available in main. just splitting out these compilers drops the specs for the gcc driver as well. find a way to build a subset of compilers, but keep support for all available compilers in the cpp/gcc drivers. Is it worth splitting out these compilers (currently gnat-4.1)
• check how -mtune=generic behaves on amd processors
• check time frame for glibc-2.5
