On large and template-heavy C++ code bases, we've observed hundreds of thousands of local typedefs targetting the same type. Previously, all pairs of such typedefs would be stored as aliases of each other at indirection level 0 in
pointerIndirection
, which proved problematic.This PR instead insists that the
base
type of a pair inpointerIndirection
is fully stripped. In this way, we store a linear rather than quadratic number of facts.@geoffw0, you wanted to have a look at this.
