[ACTIVITY] Nov 27 - Dec 1

Hi,

- Ran eon with gcc 4.7: there are much more loops similar to the one in lp#831094 that get vectorized (due to some data ref analysis improvement), so the impact of disabling peeling for such loops (i.e. loops with low loop bound) is even bigger than for 4.6, and vectorization improves the performance by 2.5%. I prefer to understand the peeling/alignment situation better and not just commit this patch (and I spent some time trying to do that).

- Fixed PR 51301 - a bug in over-promotion pattern. Proposed for merge to gcc-linaro-4.6.

- Merged the last SLP patch to gcc-linaro-4.6.
