2011-08-15Make -findirect-virtual-calls and -fterminated-vtables aliases of -fapple-kext.Bob Wilson
Outside the driver, they were already treated that way, but the driver was not giving them the same special treatment as -fapple-kext, e.g., falling back to llvm-gcc for i386/Darwin kexts. Radar 9868422. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137639 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-15Teach reference initialization from the result of a user-definedDouglas Gregor

2011-08-14Fix r137086 to actually work properly in general. PR10650.Eli Friedman
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137574 91177308-0d34-0410-b5e6-96231b3b80d8
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
2011-08-14Fix "Uninitialized" warnings on g++-4.4.NAKAMURA Takumi
In fact, they are false warnings but it seems g++-4.4 might be unable to know they must be false. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137568 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-13Reject -mkernel for i386/Darwin C++ code; fall back to llvm-gcc instead.Bob Wilson
Since -mkernel implies -fapple-kext, this just extends the current behavior for -fapple-kext to apply for -mkernel as well. Radar 9933387. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137566 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-13Add support of -x objc-cpp-output, -x objc++-cpp-output to the Driver.Nico Weber
Matches gcc, and is also required for using ccache with clang. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137563 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-13Accept -x objc++-cpp-output as an alias for -x objective-c++-cpp-outputNico Weber
This is the ObjC++ version of r129201. It's for example needed to use ccache with clang. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137560 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-13Move handling of vget_lane/vset_lane before the code that checks the type.Bob Wilson
Unlike most of the other Neon intrinsics, these are not overloaded and do not have the extra argument that specifies the vector type. This has not been fatal because the lane number operand is supposed to be an ICE and so that value has harmlessly been used as the type identifier. Radar 9901281. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137550 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-12[driver] Make sure to update the iterator end when erasing for Args.Chad Rosier
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137539 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-12Cleanup various declarations of 'Stmt*' to be 'Stmt *', etc. in libAnalyzer ↵Ted Kremenek
and libStaticAnalyzer[*]. It was highly inconsistent, and very ugly to look at. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137537 91177308-0d34-0410-b5e6-96231b3b80d8

inputs that aren't preprocessable. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137532 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-12[analyzer] change "tag" in ProgramPoint from "void*" to a ProgramPointTag*.Ted Kremenek
Having a notion of an actual ProgramPointTag will aid in introspection of the analyzer's behavior. For example, the GraphViz output of the analyzer will pretty-print the tags in a useful manner. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137529 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-12MacOSKeychainAPIChecker: If the allocated data address entered as an ↵Anna Zaks

2011-08-12[driver] Refactor a bit to enable a few fixes when generating diagnostics. ↵Chad Rosier
No functional change intended. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137524 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-12MacOSKeychainAPIChecker: Anna Zaks
Report errors earlier: on checkDeadSymbols() and clear the state after the symbol we are tracking goes out of scope. Also, perform lazy error checking. Instead of forcing the paths to be split depending one the return value of the allocator, make the return symbol depend on the allocated data symbol, which prolongs its life span to the time when the allocated data symbol becomes dead. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137523 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-12[analyzer] Nitpicks on Olaf's patch, which I meant to e-mail but then didn't inJordy Rose
time. One is cleanup, the other is me being OCD about enum group nesting. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137517 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-12MacOSKeychainAPIChecker: There is no need to use SymbolMetadata to represent ↵Anna Zaks
the allocated data symbol, we can just use the symbol corresponding to the SymbolicRegion. This simplifies tracking of the symbol, for example, SymbolMetadata needs to go through extra hoops to stay alive. Make AllocationState internal to the MacOSKeychainAPIChecker class. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137514 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-12Move the creation of the predefined typedef for Objective-C's 'id'Douglas Gregor
type over into the AST context, then make that declaration a predefined declaration in the AST format. This ensures that different AST files will at least agree on the (global) declaration ID for 'id', and eliminates one of the "special" types in the AST file format. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137429 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-12Collapse ASTWriter::WriteASTChain into ASTWriter::WriteASTCore,Douglas Gregor
eliminating a pile of redundant code (and probably some bugs in the process). The variation between chained and non-chained PCH is fairly small now anyway. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137410 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-12Optimizations for Dependent Symbol tracking (as per Ted's code review for ↵Anna Zaks
r137309): 1) Change SymbolDependTy map to keep pointers as data. And other small tweaks like making the DenseMap smaller 64->16 elements; remove removeSymbolDependencies() as it will probably not be used. 2) Do not mark dependents live more then once. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137401 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-12In the serialized AST format, make the translation unit a "predefined"Douglas Gregor
declaration that never actually gets serialized. Instead, serialize the various kinds of update records (lexical decls, visible decls, the addition of an anonymous namespace) for the translation unit, even if we're not chaining. This way, we won't have to deal with multiple loaded translation unit declarations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137395 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-11Fix a PCH crash bug where we kept a reference inside a DenseMap while the ↵Argyrios Kyrtzidis

2011-08-11The current warning in -Wnull-arithmetic for comparisons between NULL and ↵Richard Trieu
non-pointers is not very helpful. This patch will update the wording to be more helpful to users. Old warning: warning: use of NULL in arithmetic operation [-Wnull-arithmetic] return 10 <= NULL; ^ ~~~~ New warning: warning: comparison between NULL and non-pointer ('int' and NULL) [-Wnull-arithmetic] return 10 <= NULL; ~~ ^ ~~~~ git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137377 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-11When initializing a context from a particular AST file, check whetherDouglas Gregor
either "special" type has already been initialized.

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
