If you don't care what CClass is, and want to match any pointer to X<..., T, ...>, then something like: varDecl(hasType(pointerType(pointee(templateSpecializationType(hasAnyTemplateArgument(refersToType(templateTypeParmType()))))))) might be what you're looking for. If you want to match a T *anywhere* in the variable's type, then maybe something like: m varDecl(hasType(qualType(hasDescendant(qualType(templateTypeParmType()))))) is what you want. https://godbolt.org/z/QhGN5d > Oh, and thanks also for the godbolt link.
