2009-07-30What luck! Clang obtains support for refering to members of theDouglas Gregor
current instantiation when that current instantiation is a class template partial specialization. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77609 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-29Change uses of:Ted Kremenek
Type::getAsReferenceType() -> Type::getAs<ReferenceType>() Type::getAsRecordType() -> Type::getAs<RecordType>() Type::getAsPointerType() -> Type::getAs<PointerType>() Type::getAsBlockPointerType() -> Type::getAs<BlockPointerType>() Type::getAsLValueReferenceType() -> Type::getAs<LValueReferenceType>() Type::getAsRValueReferenceType() -> Type::getAs<RValueReferenceType>() Type::getAsMemberPointerType() -> Type::getAs<MemberPointerType>() Type::getAsReferenceType() -> Type::getAs<ReferenceType>() Type::getAsTagType() -> Type::getAs<TagType>() And remove Type::getAsReferenceType(), etc. This change is similar to one I made a couple weeks ago, but that was partly reverted pending some additional design discussion. With Doug's pending smart pointer changes for Types, it seemed natural to take this approach. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77510 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-29Patch to provide cast of objects in member accessFariborz Jahanian
excpression, if needed, and remove some ir-gen code now unnencessary. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77490 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-29[llvm up]Douglas Gregor
A template name can refer to a set of overloaded function templates. Model this in TemplateName, which can now refer to an OverloadedFunctionDecl that contains function templates. This removes an unspeakable hack in Sema::isTemplateName. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77488 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-29When lookup of an identifier preceding a '<' finds a set of overloadedDouglas Gregor
functions, only return those overloaded functions that are actually function templates. Note that there is still a glaring problem with treating an OverloadedFunctionDecl as a TemplateName. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77472 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-29Remove an obsolete kludge based on the previous, completely broken handling ↵Douglas Gregor
of function templates git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77464 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-29Use the new statement/expression profiling code to unique dependentDouglas Gregor
template arguments, as in template specialization types. This permits matching out-of-line definitions of members for class templates that involve non-type template parameters. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77462 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-29Fix <rdar://problem/7100524> regression: "error: incompatible operand types ↵Steve Naroff
('void *' and 'NSString *')". Remove XFAIL from 'conditional-expr-4.m' test case (which would have caught this). Also tweaked several aspects of the test to jive with the current type checking. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77453 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-28Refactor the code that produces a TemplateSpecializationType, so thatDouglas Gregor
canonicalization for dependent TemplateSpecializationTypes occurs within ASTContext::getTemplateSpecializationType. Also, move template argument canonicalization into ASTContext::getCanonicalTemplateArgument. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77388 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-25Implement C++ semantics for C-style and functional-style casts. This ↵Sebastian Redl
regresses Clang extension conversions, like vectors, but allows conversions via constructors and conversion operators. Add custom conversions to static_cast. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77076 91177308-0d34-0410-b5e6-96231b3b80d8

Fix some invalid main() methods in the test suite that were nicely exposed by the new checks. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77047 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-24Template instantiation for static data members that are defined out-of-line.Douglas Gregor
Note that this also fixes a bug that affects non-template code, where we were not treating out-of-line static data members are "file-scope" variables, and therefore not checking their initializers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77002 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-24Allow front-end 'isa' access on object's of type 'id'.Steve Naroff
Enhance test case to cover 'isa' access on interface types (clang produces an error, GCC produces a warning). Still need back-end CodeGen for ObjCIsaExpr. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76979 91177308-0d34-0410-b5e6-96231b3b80d8
