Sorry,
I amanged to accidentally commit the following change:
Index: tree-ssa-loop-niter.c
===================================================================
--- tree-ssa-loop-niter.c (revision 236816)
+++ tree-ssa-loop-niter.c (working copy)
@@ -2289,11 +2289,7 @@ number_of_iterations_exit (struct loop *
/* If NITER has simplified into a constant, update MAX. */
if (TREE_CODE (niter->niter) == INTEGER_CST)
- {
- niter->max = wi::to_widest (niter->niter);
- record_niter_bound (loop, niter->max, loop_only_exit_p (loop, exit),
- true);
- }
+ niter->max = wi::to_widest (niter->niter);
if (integer_onep (niter->assumptions))
return true;
I will revert it after re-testing.
