2011-09-08Adding FixIts to static/inline main declaration diagnostics.David Blaikie

2011-09-07Change the self-reference visitor (which gives the warning for ↵Richard Trieu
self-reference oninitalization warning of -Wuninitialized) to exclude member variables that can decay into pointers. This will cause it to no longer warn on this code: struct foo { char a[100], *e; } bar = { .e = bar.a }; git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139213 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-02Extend the ASTContext constructor to delay the initialization ofDouglas Gregor
builtin types (When requested). This is another step toward making ASTUnit build the ASTContext as needed when loading an AST file, rather than doing so after the fact. No actual functionality change (yet). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138985 91177308-0d34-0410-b5e6-96231b3b80d8

This matches gcc's logic. Second half of PR10661. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138730 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-26Introduce support for a simple module import declaration, whichDouglas Gregor
loads the named module. The syntax itself is intentionally hideous and will be replaced at some later point with something more palatable. For now, we're focusing on the semantics: - Module imports are handled first by the preprocessor (to get macro definitions) and then the same tokens are also handled by the parser (to get declarations). If both happen (as in normal compilation), the second one is redundant, because we currently have no way to hide macros or declarations when loading a module. Chris gets credit for this mad-but-workable scheme. - The Preprocessor now holds on to a reference to a module loader, which is responsible for loading named modules. CompilerInstance is the only important module loader: it now knows how to create and wire up an AST reader on demand to actually perform the module load. - We search for modules in the include path, using the module name with the suffix ".pcm" (precompiled module) for the file name. This is a temporary hack; we hope to improve the situation in the future. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138679 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-23Refactor and fix checking for initialization of flexible array members. The ↵Eli Friedman
old version had the checks scattered across the code, missed some checks, and had a couple nasty bugs in existing checks. Fixes PR10648 and another similar accepts-invalid bug. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138398 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-23Fix an incorrect note.Matt Beaumont-Gay
For the test case added to function-redecl.cpp, we were previously complaining about a mismatch in the parameter types, since the definition used the typedef'd type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138318 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-19objective-c: Bring objective-c handling of decl contextFariborz Jahanian
to modernity. Instead of passing down individual context objects from parser to sema, establish decl context in parser and have sema access current context as needed.

2011-08-14Implement function template specialization at class scope extension in ↵Francois Pichet
Microsoft mode. A new AST node is introduced: ClassScopeFunctionSpecialization. This node holds a FunctionDecl that is not yet specialized; then during the class template instantiation the ClassScopeFunctionSpecialization will spawn the actual function specialization. Example: template <class T> class A { public: template <class U> void f(U p) { } template <> void f(int p) { } // <== class scope specialization }; This extension is necessary to parse MSVC standard C++ headers, MFC and ATL code. BTW, with this feature in, clang can parse (-fsyntax-only) all the MSVC 2010 standard header files without any error. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137573 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-11Encapsulate the Objective-C id/Class/SEL "redefinition" types inDouglas Gregor
ASTContext with accessors/mutators. The only functional change is that the AST writer won't bother writing the id/Class/SEL redefinition type if it hasn't been explicitly set; previously, it ended up being written as a synonym for the built-in id/Class/SEL. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137349 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-04Match type names and give more info for out-of-line function definition errors.Kaelyn Uhrain
Having a function declaration and definition with different types for a parameter where the types have same (textual) name can occur when an unqualified type name resolves to types in different namespaces in each location. The error messages have been extended by adding notes that point to the first parameter of the function definition that doesn't match the declaration, instead of a generic "member declaration nearly matches". The generic message is still used in cases where the mismatch is not in the paramenter list, such as mismatched cv qualifiers on the member function itself. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@136891 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-03Make the type of the IntegerLiteral for bitfield paddings an actualDouglas Gregor
integer, and initialise its TypeSourceInfo. The initialisation fixes a crash when using pre-compiled preambles with C++ code-completion. From Erik Verbruggen! Fixes PR10511. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@136786 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-28Make Sema::LocallyScopedExternalDecls lazily deserialized. In theory,Douglas Gregor
we could turn this into an on-disk hash table so we don't load the whole thing the first time we need it. However, it tends to be very, very small (i.e., empty) for most precompiled headers, so it isn't all that interesting. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@136352 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-22In Objective-C, pull arbitrary attributes from overriddenJohn McCall
methods, including indirectly overridden methods like those declared in protocols and categories. There are mismatches that we would like to diagnose but aren't yet, but this is fine for now. I looked at approaches that avoided doing this lookup unless we needed it, but the infer-related-result-type checks were doing it anyway, so I left it with the same fast-path check for no previous declartions of that selector. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135743 91177308-0d34-0410-b5e6-96231b3b80d8
