------- Comment #2 from manu at gcc dot gnu dot org 2009-02-09 15:35 -------
After inlining, pp is initialized to 0.
# BLOCK 3 freq:9550, starting at line 0
# PRED: 10 [95.5%] (true,exec)
[/home/manuel/pr36823.c : 23] D.1611_4 = [/home/manuel/pr36823.c : 23]
pD.1607_2->bD.1592;
ppD.1620_9 = 0B;
# SUCC: 4 [100.0%] (fallthru,exec)
This doesn't seem to be CCP or anything else, but IPA. Something during IPA
just assumes that the undefined value is 0.
