------- Comment #3 from rguenth at gcc dot gnu dot org 2007-06-21 10:26 -------
Zdenek, I suppose this is caused by your loop-preserving for DOM.
Note this may be jump threading related:
Threaded jump 9 --> 15 to 27
(gdb) call debug_bb_n (15)
;; basic block 15, loop depth 1, count 0
;; prev block 26, next block 16
;; pred: 26 [100.0%] (fallthru,dfs_back)
;; succ: 16 [59.4%] (false,exec)
<bb 15>:
Invalid sum of outgoing probabilities 59.4%
# __first2$ptr_107 = PHI <__first2$ptr_83(26)>
so we simply forget to remove the false flag from the edge?
