------- Comment #4 from rguenth at gcc dot gnu dot org 2010-01-26 13:30 -------
Because unsplit_all_eh () does sth different for
# BLOCK 2
# PRED: ENTRY (fallthru,exec)
S2::m (this_1(D));
# SUCC: 4 (eh,exec) 3 (fallthru,exec)
# BLOCK 3
# PRED: 2 (fallthru,exec)
<L2>:
<L0>:
return;
# SUCC: EXIT
# BLOCK 4
# PRED: 2 (eh,exec)
<L1>:
# DEBUG D#2 => &this_1(D)->s1
# DEBUG this => D#2
# SUCC: 5 [100.0%] (fallthru,exec)
# BLOCK 5
# PRED: 4 [100.0%] (fallthru,exec)
<L3>:
resx 1
# SUCC:
compared to w/o debug insns. I have a patch.
