Linaro GCC 4.6 2011.11 released

 In Releases

The Linaro Toolchain Working Group is pleased to announce the 2011.11 release of Linaro GCC 4.6.

No changes were made in Linaro GCC 4.5 or Linaro GDB this month and, as such, no release has been made.

Linaro GCC 4.6 2011.11 is the ninth release in the 4.6 series. Based off the latest GCC 4.6.2 release, it contains a range of vectorizer performance improvements and general bug fixes.

Interesting changes include:

  • Updates to 4.6.2
  • A new -mtune=native flag to auto-detect the CPU of the build machine
  • A new -mtune=generic-* flag to tune for a blend of processors
  • Use of the ARMv7 unaligned access support for unaligned variables
  • Vectorization of widening shifts
  • Support for different load offsets and swap operands in SLP
  • Support for multiple types in SLP
  • Support for scheduling register moves in SMS


  • LP: #836401 ICE on a | (b << negative-constant)

The source tarballs are available from:

    I can’t seem to find the binary release for GCC 4.6 2011.11… could you point me in the right direction? 🙂

      Hi Alan,

      Do you mean the binaro cross toolchains for Ubuntu, the ones found on ?

      Effectively, the 4.6 2011.11 release is not available yet through an Ubuntu package. Stay tuned on the above page.

      Is that what you were looking for?

        The binary release like this android-toolchain-eabi-linaro-4.6-2011.09-1-1-2011-09-16_16-16-01-linux-x86.tar.bz2

        They’re usually somewhere on the downloads page or Launchpad, but I looked around for a few minutes this time and I couldn’t find it… did I overlook it somewhere?

          Android toolchains are released separately (along with the Android builds).

          This is what you’re looking for:

            Ah, ok. They used to have a nice page on the wiki, with release notes, benchmarks, pre-built binaries, etc.

            I see the binaries at least are now available from the build service. Thanks, Bernhard!
