<div dir="ltr">Well, it seems that I can get a list of redeclarations for each VarDecl, since they inherit Redeclarable<VarDecl>, but it also looks like only the second VarDecl contains the first VarDecl as a redeclaration, whereas the first VarDecl does not contain the second VarDecl as a redeclaration (only itself). It looks like Redeclarations are added on as they are redeclared, and are not added to previous Decls, although intuitively that would make more sense.<div><br></div><div>So it still looks like I'll have to recurse the AST twice, in order to get a pointer to the second VarDecl for the first VarDecl, but maybe someone can still help with an idea on how to avoid that?</div><div><br></div><div>Cheers!</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Sun, Sep 28, 2014 at 7:42 PM, Mihai Draghicioiu <span dir="ltr"><<a href="mailto:mihai.draghicioiu@gmail.com" target="_blank">mihai.draghicioiu@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Hi guys. I'm trying to get a pointer to the last VarDecl from the first VarDecl, so I can access the initialization Expr.
