PR9793: Treat substitution as an instantiation step for the purpose of the -ftemplate-depth limit. There are various ways to get an infinite (or merely huge) stack of substitutions with no intervening instantiations. This is also consistent with gcc's behavior. llvm-svn: 159907 2012-07-08 10:38:24 +08:00			`// RUN: %clang_cc1 -std=c++11 -verify %s -ftemplate-depth 2`

Use the appropriate SourceLocation for the template backtrace when doing template argument deduction. llvm-svn: 198995 2014-01-11 10:37:12 +08:00			`// expected-note 2 {{while substituting}}`

Fix bug which sometimes resulted in further diagnostics being produced after a fatal error. Previously, if a fatal error was followed by a diagnostic which was suppressed due to a SFINAETrap, we'd forget that we'd seen a fatal error. llvm-svn: 164437 2012-09-22 08:53:56 +08:00			`struct S {};`
