I want to resend this patch for consideration. I applied the patch to trunk and confirmed that it bootstraps and doesn't cause test regressions. Is this ok for trunk? Thanks, Easwaran On Fri, Dec 7, 2012 at 12:01 PM, Easwaran Raman wrote: > It seems I need to reset the debug uses of a statement

It seems I need to reset the debug uses of a statement before moving the statement itself. The attached patch starts from the leaf to root of the tree to be reassociated and places them at the point where their dependences will be met after reassociation. This bootstraps and I am running the tests.

I am unable to figure out the right way to handle the debug statements. What I tried was to find debug statements that use the SSA name defined by the statement I moved (using SSA_NAME_IMM_USE_NODE) and then moved them as well at the right place. Thus, if I have to move t1 = a + b down (after the d
