[llvm-dev] AA pass dependencies

Looking at the output of e.g.

llc -mtriple=x86_64-unknown-linux-gnu test/CodeGen/X86/pre-coalesce.ll -debug-pass=Executions

Why is it that 'Basic Alias Analysis (stateless AA impl)' is freed much earlier than 'Function Alias Analysis Results' even though the latter depends on the former (at least AFAICT by looking at lib/Analysis/AliasAnalysis.cpp)?
