Hi All, It seems to me that there is potential for doing some target independent loop invariant optimizations in the back end, but prior to instruction selection. For instance, I noticed that the loop invariant constant generated for a loop bounds check is still stuck inside the loop. Likewise constant address generated for globals accessed within a loop are generated on each iteration,
