2009-11-06If we have a C-style cast, functional cast, or a static_cast to aDouglas Gregor
class type, don't perform the array-to-pointer or function-to-pointer conversions, because we may end up binding a reference to a function or array. With this change, FileCheck now passes -fsyntax-only! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86211 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-06This patch implements Sema for clause 13.3.3.1p4.Fariborz Jahanian
It has to do with vararg constructors used as conversion functions. Code gen needs work. This is WIP. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86207 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-05Fixed two places where we needed to force completion of a typeDouglas Gregor
(without complaining if it fails) to get proper semantics: reference binding with a derived-to-base conversion and the enumeration of constructors for user-defined conversions. There are probably more cases to fix, but my prior attempt at statically ensuring that complete-type checking always happens failed. Perhaps I'll try again. With this change, Clang can parse include/llvm/*.h! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86129 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-05Implement the conditional-operator part of -Wsign-compare. TurnJohn McCall
DiagnoseSignCompare into Sema::CheckSignCompare and call it from more places. Add some enumerator tests. These seem to expose some oddities in the types we're converting C++ enumerators to; in particular, they're converting to unsigned before int, which seems to contradict 4.5 [conv.prom] p2. Note to self: stop baiting Doug in my commit messages. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86128 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-05Acting on Daniel's nagging, remove PathDiagnosticClientFactory() andTed Kremenek
migrate work in the destructors of PathDiagnosticClients from their destructors to FlushReports(). The destructors now currently call FlushReports(); this will be fixed in a subsequent patch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86108 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-05Make html::{SyntaxHighlight,HighlightMacros} take a const Preprocessor.Daniel Dunbar
This is conceptually correct, but adds a huge hack to HighlightMacros which is in fact doing all sorts of mutation to the Preprocessor. See FIXME. Chris, please review. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86107 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-05Make LookUpIdentifierInfo const. This makes the Identifiers table mutable and isDaniel Dunbar
a little fuzzy, but conceptually it's just uniquing the identifier. Chris, please review. I debated splitting into const/non-const versions where the const one propogated constness to the resulting IdentifierInfo*. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86106 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-05When instantiating a UnaryOperator, allow the resulting expression toDouglas Gregor
still be dependent or invoke an overloaded operator. Previously, we only supported builtin operators. BinaryOperator/CompoundAssignOperator didn't have this issue because we always built a CXXOperatorCallExpr node, even when name lookup didn't find any functions to save until instantiation time. Now, that code builds a BinaryOperator or CompoundAssignOperator rather than a CXXOperatorCallExpr, to save some space. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86087 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-05Modify GRExprEngine::EvalBind() to take both a "store expression" andTed Kremenek
an "assign expression", representing the expressions where the value binding occurs and the assignment takes place respectively. These are largely syntactic clues for better error reporting. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86084 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-04When starting a C++ member access expression, make sure to compute theDouglas Gregor
type of the object even when it is dependent. Specifically, this makes sure that we get the right type for "this->", which is important when performing name lookup into this scope to determine whether an identifier or operator-function-id is a template name. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86060 91177308-0d34-0410-b5e6-96231b3b80d8
