[Bug tree-optimization/24001] Simple redundancy not eliminated

[steven at gcc dot gnu dot org]

------- Comment #7 from steven at gcc dot gnu dot org  2007-10-16 13:32 -------
I would expect that tail merging (cross-jumping in gcc jargon) would merge the
two paths.

Better yet would be to optimize this earlier, and for that we need code
hoisting (re. comment #1, I think it is eliminated because we run code hoisting
at -Os).
