SourceManager::getPresumedLoc(), so that we don't try to make use of an invalid presumed location. Doing so can cause crashes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@118885 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-10Add a variant of GCC-style vector types for ARM NEON.Bob Wilson
NEON vector types need to be mangled in a special way to comply with ARM's ABI, similar to some of the AltiVec-specific vector types. This patch is mostly just renaming a bunch of "AltiVecSpecific" things, since they will no longer be specific to AltiVec. Besides that, it just adds the new "NeonVector" enum. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@118724 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-08Improve our handling of C++ [class.copy]p3, which specifies that aDouglas Gregor
constructor template will not be used to copy a class object to a value of its own type. We were eliminating all constructor templates whose specializations look like a copy constructor, which eliminated important candidates. Fixes PR8182. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@118418 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-07Remove broken support for variadic templates, along with the variousDouglas Gregor
abstractions (e.g., TemplateArgumentListBuilder) that were designed to support variadic templates. Only a few remnants of variadic templates remain, in the parser (parsing template type parameter packs), AST (template type parameter pack bits and TemplateArgument::Pack), and Sema; these are expected to be used in a future implementation of variadic templates. But don't get too excited about that happening now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@118385 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-04When canonicalizing nested-name-specifiers involving dependent namesDouglas Gregor
or dependent specializations, rip apart the dependent name/dependent specialization to recanonicalize its pieces, because nested-name-specifiers store "dependent-type::identifier" differently than types do. Fixes PR7419. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@118211 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-03Implement -working-directory.Argyrios Kyrtzidis
When -working-directory is passed in command line, file paths are resolved relative to the specified directory. This helps both when using libclang (where we can't require the user to actually change the working directory) and to help reproduce test cases when the reproduction work comes along. --FileSystemOptions is introduced which controls how file system operations are performed (currently it just contains the working directory value if set). --FileSystemOptions are passed around to various interfaces that perform file operations. --Opening & reading the content of files should be done only through FileManager. This is useful in general since file operations will be abstracted in the future for the reproduction mechanism. FileSystemOptions is independent of FileManager so that we can have multiple translation units sharing the same FileManager but with different FileSystemOptions.
