2009-10-17Add IdentiferInfo::getNameStr() -> StringRef.Daniel Dunbar
Also, add getNameStart as a synonym for getName(). getName() is now deprecated, when all clients are updated then getNameStr() should be renamed to getName(). PR5218. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84306 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-17Add 'UseBumpPtrAllocator' flag to ASTUnit::LoadFromPCHFile() to cause the ↵Ted Kremenek
created ASTContext to use its own BumpPtrAllocator to allocate ASTs. Change clang_createTranslationUnit (CIndex) to pass 'UseBumpPtrAllocator = true' to ASTUnit::LoadFromPCHFile(). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84296 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-17Merge the "types" and "declarations" blocks in the precompiled headerDouglas Gregor
format, so that we don't end up with multiple declaration and types blocks. Also, fix a few obscure bugs with PCH loading and generation: - If the DeclIDs DenseMap reallocates while we are writing a declaration (due to recursively writing other declarations), we could end up writing a bad ID to ExternalDefinitions. - When loading an ArrayLoc (part of DeclaratorInfo), we need to set the size expression to NULL if no size expression was provided. PCH -> AST rewriting is still partly broken, unfortunately. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84293 91177308-0d34-0410-b5e6-96231b3b80d8

builtin function ambiguity. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84289 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-16While writing source-location entries to a PCH file, go through anDouglas Gregor
interface that can load those source-location entries on demand (from another PCH file). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84287 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-16Allow TypeLocs to be fully initialized with a single SourceLocation. ThisJohn McCall
will be the keystone of converting existing rewrites to be rewrites on TypeLocs. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84286 91177308-0d34-0410-b5e6-96231b3b80d8

core PCH reader/writer implementation files. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84278 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-16Add an accessor to extra the type directly from a DeclaratorInfoJohn McCall
without an opaque call. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84277 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-16Make CIndex and c-index-test a little bit more robust. The onlyDouglas Gregor
substantive change is that clang_getCursorSource() now returns the file in which a macro was instantiated when the cursor points into a macro instantiation, rather than crashing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84275 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-16Provide 'static' version of BinaryOperator::isShiftOp().Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84268 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-16Keep track of whether declararions were loaded from a precompiledDouglas Gregor
header or not via a new "PCHLevel" field in Decl. We currently use this information to help CIndex filter out declarations that came from a precompiled header (rather than from an AST file). Further down the road, it can be used to help implement multi-level precompiled headers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84267 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-16Add support for a chain of stat caches in the FileManager, rather thanDouglas Gregor
only supporting a single stat cache. The immediate benefit of this change is that we can now generate a PCH/AST file when including another PCH file; in the future, the chain of stat caches will likely be useful with multiple levels of PCH files. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84263 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-16Remove the ConstantArrayType subtypes. This information is preserved in theJohn McCall
TypeLoc records for declarations; it should not be necessary to represent it directly in the type system. Please complain if you were using these classes and feel you can't replicate previous functionality using the TypeLoc API. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84222 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-15ConcreteTypeLoc subclasses which call getInnerTypeLoc() should get aJohn McCall
compile-time error now; moreover, remove the need for an explicit hasInnerType() call. Thanks to Doug Gregor for the metaprogramming approach. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84215 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-15Simplify checking of explicit template specialization/explicitDouglas Gregor
instantiation redeclaration semantics for function template specializations and member functions of class template specializations. Also, record the point of instantiation for explicit-instantiated functions and static data members. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84188 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-15Check the interactions between explicit instantiations and templateDouglas Gregor
specializations. Work in progress; there's more cleanup required to actually use the new CheckSpecializationInstantiationRedecl checker uniformly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84185 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-15Diagnose explicit instantiations of function templates and memberDouglas Gregor
functions/static data members of class template specializations that do not have definitions. This is the latter part of [temp.explicit]p4; the former part still needs more testing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84182 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-15More explicit template instantiation. Now we're checking for moreDouglas Gregor
cases where an explicit instantiation requires a definition; the remainder of these checks will come with the implementation of paragraph 4 of [temp.explicit]. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84181 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-15Better living through metaprogramming. Create a base class which abstractsJohn McCall
most of the unsafe boilerplate out of TypeLoc. Create a QualifiedLoc class to represent the idea that we *might* start representing source locations of qualifiers. Dealing with qualifiers explicitly like this also lets us efficiently ignore them in all the concrete cases. This should make it obvious and easy to add new TypeLoc subclasses. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84168 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-14CheckTemplateSpecializationScope isn't going to be used for explicitDouglas Gregor
instantiations, since the requirements are too different from those for template specializations. Simplify it slightly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84156 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-14fix some cfstring related issues: Chris Lattner
1) -fwritable-string does affect the non-utf16 version of cfstrings just not the utf16 ones. 2) utf16 strings should always be marked constant, as the __TEXT segment is readonly. 3) The name of the global doesn't matter, remove it from TargetInfo. 4) Trust the asmprinter to drop cstrings into the right section, like llvmgcc does now. This fixes rdar://7115750 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84077 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-13Improve diagnostics when the parser encounters a declarator with anDouglas Gregor
unknown type name, e.g., foo::bar x; when "bar" does not refer to a type in "foo". With this change, the parser now calls into the action to perform diagnostics and can try to recover by substituting in an appropriate type. For example, this allows us to easily diagnose some missing "typename" specifiers, which we now do: test/SemaCXX/unknown-type-name.cpp:29:1: error: missing 'typename' prior to dependent type name 'A<T>::type' A<T>::type A<T>::f() { return type(); } ^~~~~~~~~~ typename Fixes PR3990. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84053 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-13Unify our diagnostic printing for errors of the form, "we didn't likeDouglas Gregor
what we found when we looked into <blah>", where <blah> is a DeclContext*. We can now format DeclContext*'s in nice ways, e.g., "namespace N", "the global namespace", "'class Foo'". This is part of PR3990, but we're not quite there yet. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84028 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-13When explicitly specializing a member that is a template, mark theDouglas Gregor
template as a specialization. For example, this occurs with: template<typename T> struct X { template<typename U> struct Inner { /* ... */ }; }; template<> template<typename T> struct X<int>::Inner { T member; }; We need to treat templates that are member specializations as special in two contexts: - When looking for a definition of a member template, we look through the instantiation chain until we hit the primary template *or a member specialization*. This allows us to distinguish between the primary "Inner" definition and the X<int>::Inner definition, above. - When computing all of the levels of template arguments needed to instantiate a member template, don't add template arguments from contexts outside of the instantiation of a member specialization, since the user has already manually substituted those arguments. Fix up the existing test for p18, which was actually wrong (but we didn't diagnose it because of our poor handling of member specializations of templates), and add a new test for member specializations of templates. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83974 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-13Improve the internal representation and semantic analysis of friendDouglas Gregor
function templates. This commit ensures that friend function templates are constructed as FunctionTemplateDecls rather than partial FunctionDecls (as they previously were). It then implements template instantiation for friend function templates, injecting the friend function template only when no previous declaration exists at the time of instantiation. Oh, and make sure that explicit specialization declarations are not friends. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83970 91177308-0d34-0410-b5e6-96231b3b80d8
