[c++20] Implement P0846R0: allow (ADL-only) calls to template-ids whosetemplate name is not visible to unqualified lookup.In order to support this without a severe degradation in our ability todiagnose typos in template names, this change significantly restructuresthe way we handle template-id-shaped syntax for which lookup of thetemplate name finds nothing.Instead of eagerly diagnosing an undeclared template name, we now form aplaceholder template-name representing a name that is known to not findany templates. When the parser sees such a name, it attempts todisambiguate whether we have a less-than comparison or a template-id.Any diagnostics or typo-correction for the name are delayed until itspoint of use.The upshot should be a small improvement of our diagostic qualityoverall: we now take more syntactic context into account when trying toresolve an undeclared identifier on the left hand side of a '<'. Infact, this works well enough that the backwards-compatible portion (foran undeclared identifier rather than a lookup that finds functions butno function templates) is enabled in all language modes.llvm-svn: 360308 List of files: /llvm-project-15.0.7/clang/test/CXX/temp/temp.spec/temp.explicit/p5.cpp

Lit C++11 Compatibility Patch #713 tests have been updated for C++11 compatibility.Differential Revision: http://reviews.llvm.org/D19068llvm-svn: 266239 List of files: /llvm-project-15.0.7/clang/test/CXX/temp/temp.spec/temp.explicit/p5.cpp

ab6bc1d1 - Make the -Wc++11-compat warnings ignored by default, so we don't break

Tue, 25 Oct 2011 03:07:45 +0000

Make the -Wc++11-compat warnings ignored by default, so we don't breakvalid C++98/03 code. However, add these warnings to -Wall, for thosewho obviously already like clean code.llvm-svn: 142903 List of files: /llvm-project-15.0.7/clang/test/CXX/temp/temp.spec/temp.explicit/p5.cpp

c97d7a2c - The C++98/03 standard is disturbingly silent about out-of-scope

Tue, 11 May 2010 17:39:34 +0000

The C++98/03 standard is disturbingly silent about out-of-scopeexplicit instantiations of template. C++0x clarifies the intent(they're ill-formed in some cases; see [temp.explicit] fordetails). However, one could squint at the C++98/03 standard andconclude they are permitted, so reduce the error to a warning(controlled by -Wc++0x-compat) in C++98/03 mode.llvm-svn: 103482 List of files: /llvm-project-15.0.7/clang/test/CXX/temp/temp.spec/temp.explicit/p5.cpp

8fbe78f6 - Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.

Tue, 15 Dec 2009 20:14:24 +0000

Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'. - This is designed to make it obvious that %clang_cc1 is a "test variable" which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it can be useful to redefine what gets run as 'clang -cc1' (for example, to set a default target).llvm-svn: 91446 List of files: /llvm-project-15.0.7/clang/test/CXX/temp/temp.spec/temp.explicit/p5.cpp
