------- Comment #1 from rguenth at gcc dot gnu dot org 2007-09-29 19:05 -------
Confirmed. Happens after final_cleanup of the following function:
;; Function void somefunction() (_Z12somefunctionv)
void somefunction() ()
{
# BLOCK 2 freq:10000
# PRED: ENTRY [100.0%] (fallthru,exec)
somemethod (0B);
goto <bb 4>;
# SUCC: 3 (ab,eh,exec) 4 [100.0%] (fallthru,exec)
# BLOCK 3
# PRED: 2 (ab,eh,exec)
<L3>:;
<<<exception object>>> = <<<exception object>>>;
<<<filter object>>> = <<<filter object>>>;
resx 1;
# SUCC:
# BLOCK 4 freq:10000
# PRED: 2 [100.0%] (fallthru,exec)
return;
# SUCC: EXIT [100.0%]
}
