2010-04-28Completely reimplement __builtin_offsetof, based on a patch by RobertoDouglas Gregor
Amadini. This change introduces a new expression node type, OffsetOfExpr, that describes __builtin_offsetof. Previously, __builtin_offsetof was implemented using a unary operator whose subexpression involved various synthesized array-subscript and member-reference expressions, which was ugly and made it very hard to instantiate as a template. OffsetOfExpr represents the AST more faithfully, with proper type source information and a more compact representation. OffsetOfExpr also has support for dependent __builtin_offsetof expressions; it can be value-dependent, but will never be type-dependent (like sizeof or alignof). This commit introduces template instantiation for __builtin_offsetof as well. There are two major caveats to this patch: 1) CodeGen cannot handle the case where __builtin_offsetof is not a constant expression, so it produces an error. So, to avoid regressing in C, we retain the old UnaryOperator-based __builtin_offsetof implementation in C while using the shiny new OffsetOfExpr implementation in C++. The old implementation can go away once we have proper CodeGen support for this case, which we expect won't cause much trouble in C++. 2) __builtin_offsetof doesn't work well with non-POD class types, particularly when the designated field is found within a base class. I will address this in a subsequent patch. Fixes PR5880 and a bunch of assertions when building Boost.Python tests. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@102542 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-28Changed signature of GenerateMessageSend() function to pass the ↵David Chisnall
ObjCInterfaceDecl for class messages and removed the boolean IsClassMessage argument, which wasn't used anywhere. Emitted some metadata on message sends to allow a later pass to do some speculative inlining of class methods (GNU runtime). Speculative inlining of instance methods requires type feedback to be useful (work in progress), but for class methods it works quite nicely. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@102514 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-27When explicitly building a temporary object (CXXTemporaryObjectExpr),Douglas Gregor
keep track of whether we need to zero-initialize storage prior to calling its constructor. Previously, we were only tracking this when implicitly constructing the object (a CXXConstructExpr). Fixes Boost's value-initialization tests, which means that the Boost.Config library now passes all of its tests. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@102461 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-27Diagnose the use of abstract types as array element types. Previously,Douglas Gregor
we were relying on checking for abstract class types when an array type was actually used to declare a variable, parameter, etc. However, we need to check when the construct the array for, e.g., SFINAE purposes (see DR337). Fixes problems with Boost's is_abstract type trait. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@102452 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-27During template instantiation, set the naming class ofDouglas Gregor
UnresolvedLookupExpr and UnresolvedMemberExpr by substituting the naming class we computed when building the expression in the template... ... which we didn't always do correctly. Teach UnresolvedMemberExpr::getNamingClass() all about the new representation of injected-class-names in templates, so that it can return a naming class that is the current instantiation. Also, when decomposing a template-id into its template name and its arguments, be sure to set the naming class on the LookupResult structure. Fixes PR6947 the right way. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@102448 91177308-0d34-0410-b5e6-96231b3b80d8
