2009-10-27Split AddDefaultSystemIncludePaths into C, C++ and framework specific functions.Rafael Espindola
The user visible changes are: *) Frameworks are only searched on OS X *) The Cygwin c++ headers are now marked as c++ aware. I am almost sure that not marking them was a bug. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@85240 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-25Audit the code for places where it is assumed that every base specifier ↵Sebastian Redl

2009-10-24Preserve type source information in TypedefDecls. Preserve it acrossJohn McCall
template instantiation. Preserve it through PCH. Show it off to the indexer. I'm healthily ignoring the vector type cases because we don't have a sensible TypeLoc implementation for them anyway. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84994 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-23Remove OriginalTypeParmDecl; the original type is the one specifiedJohn McCall
in the DeclaratorInfo, if one is present. Preserve source information through template instantiation. This is made more complicated by the possibility that ParmVarDecls don't have DIs, which is possibly worth fixing in the future. Also preserve source information for function parameters in ObjC method declarations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84971 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-23Eliminate QualifiedDeclRefExpr, which captured the notion of aDouglas Gregor
qualified reference to a declaration that is not a non-static data member or non-static member function, e.g., namespace N { int i; } int j = N::i; Instead, extend DeclRefExpr to optionally store the qualifier. Most clients won't see or care about the difference (since QualifierDeclRefExpr inherited DeclRefExpr). However, this reduces the number of top-level expression types that clients need to cope with, brings the implementation of DeclRefExpr into line with MemberExpr, and simplifies and unifies our handling of declaration references. Extended DeclRefExpr to (optionally) store explicitly-specified template arguments. This occurs when naming a declaration via a template-id (which will be stored in a TemplateIdRefExpr) that, following template argument deduction and (possibly) overload resolution, is replaced with a DeclRefExpr that refers to a template specialization but maintains the template arguments as written. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84962 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-23Fix integer overflow in PCHReader when reading the length of anTed Kremenek
identifier. This caused a crash when reading PCH files that contained long identifier names. The issue is that 'StrLenPtr' was previously a 'const char *', meaning the byte loaded from it would be interpretted as a signed integer. If the topmost bit was set, conversion to 'unsigned' would extend that bit, causing an overflow. The solution is to make 'StrLenPtr' an 'unsigned char *', always treating the value as an unsigned integer. This fixes: <rdar://problem/7328900> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84925 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-23FunctionTypeLocs don't necessarily provide ParmVarDecls, so don't crash ifJohn McCall
one was PCH'ed without any. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84920 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-22When building types from declarators, instead of building two types (one forJohn McCall
the DeclaratorInfo, one for semantic analysis), just build a single type whose canonical type will reflect the semantic analysis (assuming the type is well-formed, of course). To make that work, make a few changes to the type system: * allow the nominal pointee type of a reference type to be a (possibly sugared) reference type. Also, preserve the original spelling of the reference type. Both of these can be ignored on canonical reference types. * Remove ObjCProtocolListType and preserve the associated source information on the various ObjC TypeLocs. Preserve the spelling of protocol lists except in the canonical form. * Preserve some level of source type structure on parameter types, but canonicalize on the canonical function type. This is still a WIP. Drops code size, makes strides towards accurate source location representation, slight (~1.7%) progression on Cocoa.h because of complexity drop. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84907 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-20Add destructor and cleanup code to LocationContext (fixing some leaks). ↵Ted Kremenek
Along the way, have AnalysisManager periodically cleanup its AnalysisContextManager and LocationContextManager objects, as they don't need to forever retain all the CFGs ever created when analyzing a file. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84684 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-20Refine the type of the first parameter to block invoke functions.Mike Stump
WIP. I have yet to find the magic incantation to get the structure type to be defined. If someone has a pointer, love to hear it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84590 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-19The constructor for ASTUnit now takes a DiagnosticClient*, allowing uses of ↵Ted Kremenek
ASTUnit to specify alternate DiagnosticClients. To match this API, ASTUnit::LoadFromPCHFile() now takes a corresponding DiagnosticClient* argument as well. The DiagnosticClient object is destroyed when the ASTUnit object is destroyed. The CIndex library now uses this API to create a 'IgnoreDiagnosticsClient' that simply silences diagnostics when using the clang_createTranslationUnitFromSourceFile() function. This fixes <rdar://problem/7312058>. This API can change in the future as we add more flexibility for clients. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84539 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-18When performing template-substitution into a type, don't just replace theJohn McCall
TemplateTypeParmType with the substituted type directly; instead, replace it with a SubstTemplateTypeParmType which will note that the type was originally written as a template type parameter. This makes it reasonable to preserve source information even through template substitution. Also define the new SubstTemplateTypeParmType class, obviously. For consistency with current behavior, we stringize these types as if they were the underlying type. I'm not sure this is the right thing to do. At any rate, I paled at adding yet another clause to the don't-desugar 'if' statement, so I extracted a function to do it. The new function also does The Right Thing more often, I think: e.g. if we have a chain of typedefs leading to a vector type, we will now desugar all but the last one. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84412 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-18Clone the full Type hierarchy into the TypeLoc hierarchy. NormalizeJohn McCall
TypeLoc class names to be $(Type classname)Loc. Rewrite the visitor. Provide skeleton implementations for all the new TypeLocs. Handle all cases in PCH. Handle a few more cases when inserting location information in SemaType. It should be extremely straightforward to add new location information to existing TypeLoc objects now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84386 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
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

2009-10-16Keep 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
