[PATCH] D70236: [AST] Use written names instead of `type-param-0-0` in more cases when printing types and decls.

[Haojian Wu via Phabricator via cfe-commits]

hokein added inline comments.


================
Comment at: clang/lib/AST/DeclPrinter.cpp:642
     DeclPrinter TArgPrinter(POut, SubPolicy, Context, Indentation);
-    TArgPrinter.printTemplateArguments(*TArgs);
+    if (const auto *TArgInfo = D->getTemplateSpecializationArgsAsWritten())
+      TArgPrinter.printTemplateArguments(TArgInfo->arguments());
----------------
so here, do we need to respect the `SubPolicy.PrintCanonicalTypes` ?


================
Comment at: clang/lib/AST/DeclPrinter.cpp:1101
       Out << ", ";
-    if (Params) {
-      if (A.getKind() == TemplateArgument::Type)
-        if (auto T = A.getAsType()->getAs<TemplateTypeParmType>()) {
-          auto P = cast<TemplateTypeParmDecl>(Params->getParam(T->getIndex()));
-          Out << *P;
-          continue;
-        }
-      if (A.getKind() == TemplateArgument::Template) {
-        if (auto T = A.getAsTemplate().getAsTemplateDecl())
-          if (auto TD = dyn_cast<TemplateTemplateParmDecl>(T)) {
-            auto P = cast<TemplateTemplateParmDecl>(
-                                              Params->getParam(TD->getIndex()));
-            Out << *P;
-            continue;
-          }
-      }
-      if (A.getKind() == TemplateArgument::Expression) {
-        if (auto E = dyn_cast<DeclRefExpr>(A.getAsExpr()))
-          if (auto N = dyn_cast<NonTypeTemplateParmDecl>(E->getDecl())) {
-            auto P = cast<NonTypeTemplateParmDecl>(
-                                               Params->getParam(N->getIndex()));
-            Out << *P;
-            continue;
-          }
-      }
-    }
     A.print(Policy, Out);
   }
----------------
nit: we can inline A, just `Args[I].print(...)`.


================
Comment at: clang/lib/AST/DeclPrinter.cpp:1112
+      Out << ", ";
+    A.getArgument().print(Policy, Out);
+  }
----------------
the same here.
