clarify their purpose. Firstly, call them "...Mixin" types so it is clear that there is no type hierarchy being formed here. Secondly, use the term 'Info' to clarify that they aren't adding any interesting *semantics* to the passes or analyses, just exposing APIs used by the management layer to get information about the pass or analysis. Thanks to Manuel for helping pin down the naming confusion here and come up with effective names to address it. In case you already have some out-of-tree stuff, the following should be roughly what you want to update: perl -pi -e 's/\b(Pass|Analysis)Base\b/\1InfoMixin/g' git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@263217 91177308-0d34-0410-b5e6-96231b3b80d8
