Fix a thinko where I didn't update a consistency check for PackExpansionType in the AST reader. We need more testing for variadic templates + PCH, but this fixes PR9073. llvm-svn: 124662

// Test this without pch.
Update all tests other than Driver/std.cpp to use -std=c++11 rather than -std=c++0x. Patch by Ahmed Charles! llvm-svn: 141900

add option to instantiate templates already in the PCH Add -fpch-instantiate-templates which makes template instantiations be performed already in the PCH instead of it being done in every single file that uses the PCH (but every single file will still do it as well in order to handle its own instantiations). I can see 20-30% build time saved with the few tests I've tried. The change may reorder compiler output and also generated code, but should be generally safe and produce functionally identical code. There are some rare cases that do not compile with it, such as test/PCH/pch-instantiate-templates-forward-decl.cpp. If template instantiation bailed out instead of reporting the error, these instantiations could even be postponed, which would make them work. Enable this by default for clang-cl. MSVC creates PCHs by compiling them using an empty .cpp file, which means templates are instantiated while building the PCH and so the .h needs to be self-contained, making test/PCH/pch-instantiate-templates-forward-decl.cpp to fail with MSVC anyway. So the option being enabled for clang-cl matches this. Differential Revision: https://reviews.llvm.org/D69585

Prior to adding the new "expected-no-diagnostics" directive to VerifyDiagnosticConsumer, make the necessary adjustment to 580 test-cases which will henceforth require this new directive. llvm-svn: 166280

PR9023: A template template parameter whose template parameter list contains an unexpanded parameter pack is a pack expansion. Thus, as with a non-type template parameter which is a pack expansion, it needs to be expanded early into a fixed list of template parameters. Since the expanded list of template parameters is not itself a parameter pack, it is permitted to appear before the end of the template parameter list, so also remove that restriction (for both template template parameter pack expansions and non-type template parameter pack expansions). llvm-svn: 163369
