That depends, can you provide more context? In general, there isn't a
cheap way of going from a Decl* to a list of users like in LLVM IR, but
you can use add some code to Sema::DiagnoseUseOfDecl to find places
where the Decl is used, or traverse the AST using a ConstStmtVisitor or
RecursiveASTVisitor, looking for a DeclRefExpr/MemberExpr that refers to
a specific variable. What kinds of Decls are you looking for, and what
operation are you planning on doing with it's users?
