Rafael Espindola	820fa707b1	Mark all subsequent decls used. In the source static void f(); static void f(); template<typename T> static void g() { f(); } static void f() { } void h() { g<int>(); } the call to f refers to the second decl, but it is only marked used at the end of the translation unit during instantiation, after the third f decl has been linked in. With this patch we mark all subsequent decls used, so that it is easy to check if a symbol is used or not. llvm-svn: 171888	2013-01-08 19:43:34 +00:00
Rafael Espindola	1779760cb4	Fix a regression from the previous commit. Template instantiation can set the canonical decl to used after subsequent decls have been chained, so we have to check that too. llvm-svn: 171088	2012-12-26 04:38:44 +00:00
Rafael Espindola	dfa5f9b511	Use the most recent redecl to decide if it is needed. This fixes pr14691, which I think is a regression from r168519. llvm-svn: 171077	2012-12-26 00:13:29 +00:00

Mark all subsequent decls used.

In the source

  static void f();
  static void f();
  template<typename T>
  static void g() {
    f();
  }
  static void f() {
  }
  void h() {
    g<int>();
  }

the call to f refers to the second decl, but it is only marked used at the end
of the translation unit during instantiation, after the third f decl has been
linked in.

With this patch we mark all subsequent decls used, so that it is easy to check
if a symbol is used or not.

Fix a regression from the previous commit.

Template instantiation can set the canonical decl to used after subsequent
decls have been chained, so we have to check that too.

Use the most recent redecl to decide if it is needed.

This fixes pr14691, which I think is a regression from r168519.
