[Bug tree-optimization/41442] missed optimization for boolean expression

[rguenth at gcc dot gnu dot org]

------- Comment #2 from rguenth at gcc dot gnu dot org  2009-09-23 08:50 -------
You wound need to enable PRE implement code hoisting to remove the redundant
load (or write the condition as p2->next || (p1->next && !p2->next)).
PRE is run too late
to help generate optimal code though as ifcombine runs before it and
ifcombine wouldn't deal with the if-converted form that is present then.
