...9;t preserve AliasAnalysis. Hmm...that might be related. The situation here is that an analysis pass depended on by another analysis pass isn't re-run even though it's not preserved by any pass.

Ok, I've been struggling with this for two days and hopefully someone can help me out. I have a set of passes, analysis passes A, B, C, D and transformation passes E and F. Pass C depends on pass A and pass D depends on pass B. Pass E depends on C and D and does not preserve any analysis pass. Pass F depeds on pass A and pass C. Pass F runs after pass E.
