== GCC ==

* Fixed vectorizer bug causing unaligned memory accesses (LP 1010826 / GCC PR 53636); checked in to GCC mainline and Linaro GCC 4.7. Backports to FSF 4.7 and Linaro GCC 4.6 are under way.

* Investigated vectorizer performance regression reported by Mans; main problem seems to be lack of use of the vectorizer cost model by default on ARM, but other aspects of the vectorized code could be improved as well.

* Created blueprint to tune vectorizer cost mode on ARM and enable it by default.

* Ongoing work on reassociation pass.

Mit freundlichen Gruessen / Best Regards
