[Bug tree-optimization/34355] ICE: invariant not recomputed when ADDR_EXPR changed with -ftree-parallelize-loops

[rguenth at gcc dot gnu dot org]

------- Comment #1 from rguenth at gcc dot gnu dot org  2007-12-06 10:37 -------
Confirmed.

eliminate_local_variables_1 changes &Express[0] to &(*Express.96_73)[0]
without re-computing invariantness.

With the structure of eliminate_local_variables_stmt (it seems to operate
on non-gimple), it looks like it would require a second walk over the stmt
to recompute invariantness (or to make sure to do this at gimplification time).
Or to walk depth-first.

I'll leave that to Zdenek to figure out.
