Hello,
Writes to global memory are not hoisted out of a computation loop.
Try this with the LNO branch, iirc it can do this.
Not as of gcc (GCC) 3.5-tree-ssa-lno 20040430 (merged 20040425) (-O2 -ftree-loop-optimize -ffast-math), neither with static nor without.
tree-ssa aliasing probably does not take restricted pointers into account, since it decides that all the accesses in the loop may alias.
