2010-04-06Implement the protected access restriction ([class.protected]), which requiresJohn McCall
that protected members be used on objects of types which derive from the naming class of the lookup. My first N attempts at this were poorly-founded, largely because the standard is very badly worded here. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100562 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-02Rework our handling of copy construction of temporaries, which was aDouglas Gregor
poor (and wrong) approximation of the actual rules governing when to build a copy and when it can be elided. The correct implementation is actually simpler than the approximation. When we only enumerate constructors as part of initialization (e.g., for direct initialization or when we're copying from a class type or one of its derived classes), we don't create a copy. When we enumerate all conversion functions, we do create a copy. Before, we created some extra copies and missed some others. The new test copy-initialization.cpp shows a case where we missed creating a (required, non-elidable) copy as part of a user-defined conversion, which resulted in a miscompile. This commit also fixes PR6757, where the missing copy made us reject well-formed code in the ternary operator. This commit also cleans up our handling of copy elision in the case where we create an extra copy of a temporary object, which became necessary now that we produce the right copies. The code that seeks to find the temporary object being copied has moved into Expr::getTemporaryObject(); it used to have two different not-quite-the-same implementations, one in Sema and one in CodeGen. Note that we still do not attempt to perform the named return value optimization, so we miss copy elisions for return values and throw expressions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100196 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-01Relax the typesafty rules of block pointers types whichFariborz Jahanian
take'id' or return 'id' in their type. Fixes radar 7814131. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100129 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-31Change the representation of dependent elaborated-type-specifiersDouglas Gregor
(such as "class T::foo") from an ElaboratedType of a TypenameType to a DependentNameType, which more accurately models the underlying concept. Improve template instantiation for DependentNameType nodes that represent nested-name-specifiers, by performing tag name lookup and checking the resulting tag appropriately. Fixes PR5681. There is still much testing and cleanup to do in this area. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100054 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-31Extend DependentNameType with a keyword enum that specifies whetherDouglas Gregor
this was parsed as a typename-specifier, elaborated-type-specifier (including the kind), or just a dependent qualified type name. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100039 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-30Introduce a new kind of derived-to-base cast which bypasses the need forJohn McCall
null checks, and make sure we elide null checks when accessing base class members. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99963 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-30Remember the regparm attribute in FunctionType::ExtInfo.Rafael Espindola
Fixes PR3782. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99940 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-30Propagate the "found declaration" (i.e. the using declaration instead ofJohn McCall
the underlying/instantiated decl) through a lot of API, including "intermediate" MemberExprs required for (e.g.) template instantiation. This is necessary because of the access semantics of member accesses to using declarations: only the base class *containing the using decl* need be accessible from the naming class. This allows us to complete an access-controlled selfhost, if there are no recent regressions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99936 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-30the big refactoring bits of PR3782.Rafael Espindola
This introduces FunctionType::ExtInfo to hold the calling convention and the noreturn attribute. The next patch will extend it to include the regparm attribute and fix the bug. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99920 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-30Introduce new AST statistics that keep track of the number of isa (orDouglas Gregor
dyn_cast) invocations for C++ and Objective-C types, declarations, expressions, and statements. The statistics will be printed when -print-stats is provided to Clang -cc1, with results such as: 277073 clang - Number of checks for C++ declaration nodes 13311 clang - Number of checks for C++ expression nodes 18 clang - Number of checks for C++ statement nodes 174182 clang - Number of checks for C++ type nodes 92300 clang - Number of checks for Objective-C declaration nodes 9800 clang - Number of checks for Objective-C expression nodes 7 clang - Number of checks for Objective-C statement nodes 65733 clang - Number of checks for Objective-C type nodes The statistics are only gathered when NDEBUG is not defined, since they introduce potentially-expensive operations into very low-level routines (isa). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99912 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-30Add Support for 'warn_unused_result" attribute onFariborz Jahanian
objective-c methods. (radar 7418262). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99903 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-29When copying a partial diagnostic into a DependentDiagnostic, allocateDouglas Gregor
storage for that partial diagnostic via the ASTContext's BumpPtrAllocator rather than using up slots in the ASTContext's cache. Now that we do this, we don't have to worry about destroying dependent diagnostics when destroying a DependentStoredDeclsMap. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99854 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-29Optimize PartialDiagnostic's memory-allocation behavior by placing aDouglas Gregor
cache of PartialDiagnostic::Storage objects into an allocator within the ASTContext. This eliminates a significant amount of malloc traffic, for a 10% performance improvement in -fsyntax-only wall-clock time with 403.gcc's combine.c. Also, eliminate the RequireNonAbstractType hack I put in earlier, which was but a symptom of this larger problem. Fixes <rdar://problem/7806091>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99849 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-29When collecting virtual bases it's very important to use the canonical type ↵Anders Carlsson
of the base class. Otherwise, we might add the same virtual base class twice if the virtual base is an instantiated template. Fixes PR6251. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99829 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-26Properly account for redeclarations when explicitly instantiating class ↵John McCall
templates. What happens here is that we actually turn the first declaration into a definition, regardless of whether it was actually originally a definition, and furthermore we do this all after we've instantiated all the declarations. This exposes a bug in my DefinitionData patch where it was only setting the DefinitionData for previous declarations, not future declarations. Fortunately, there's an iterator for that. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99657 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-24Implement a framework for the delay of arbitrary diagnostics withinJohn McCall
templates. So delay access-control diagnostics when (for example) the target of a friend declaration is a specific specialization of a template. I was surprised to find that this was required for an access-controlled selfhost. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99383 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-23Implement computation of the final overriders for each virtualDouglas Gregor
function within a class hierarchy (C++ [class.virtual]p2). We use the final-overrider computation to determine when a particular class is ill-formed because it has multiple final overriders for a given virtual function (e.g., because two virtual functions override the same virtual function in the same virtual base class). Fixes PR5973. We also use the final-overrider computation to determine which virtual member functions are pure when determining whether a class is abstract or diagnosing the improper use of an abstract class. The prior approach to determining whether there were any pure virtual functions in a class didn't cope with virtual base class subobjects properly, and could not easily be fixed to deal with the oddities of subobject hiding. Fixes PR6631. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99351 91177308-0d34-0410-b5e6-96231b3b80d8
