I don't have time to work on these (new job), so unassigning.

        * tree-vrp.c (find_conditional_asserts): Update comments.

        (etc.)

>From today's .vars dump: 
 
  # BLOCK 4 
  # PRED: 3 [95.0%]  (false,exec) 
<L3>:; 
  c = c - 1; 
  ivtmp.54 = ivtmp.54 - 8; 
  if (c != 0) goto <L2>; else goto <L16>; 
  # SUCC: 3 [75.0%]  (dfs_back,true,exec) 10 [25.0%]  (loop_exit,false,exec) 
 
(...) 
 
  # BLOCK 10 
  # PRED: 4 [25.0%]  (loop_exit,false,exec) 
<L16>:; 
  buf[0] = (unsigned char) ((signed char) c | 64); 
  len = 1; 
  goto <bb 9> (<L9>); 
  # SUCC: 9 [100.0%]  (fallthru,exec) 
 
So this is still not fixed.

Kazu and I discussed a plan for how to fix this, I'll try implementing it.
