[PATCH] D10368: Analyze recursive PHI nodes in BasicAA

[Tobias Edler von Koch]

tobiasvk updated this revision to Diff 29448.
tobiasvk added a comment.

Change patch to use a load of undef, instead of just an undef, as the index for
the temporary GEP. This should make it safe even if aliasGEP ever gets smarter
about undefs.
