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
