used during compilation. - There is no easy way to define this group properly, unfortunately, and maybe this is a losing strategy. For now this is unambiguous more friendly, though. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91940 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-22When transforming a C++ "new" expression that was not explicitly givenDouglas Gregor
a size, check whether the transformed type is itself an array type. If so, take the major array bound as the size to allocate. Fixes PR5833. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91907 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-22Switch initialization of parameters in a call over toDouglas Gregor
InitializationSequence (when a FunctionDecl is present). This required a few small fixes to initialization sequences: - Make sure to use the adjusted parameter type for initialization of function parameters. - Implement transparent union calling semantics in C git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91902 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-22Make sure that we mangle overloaded operators that are member functions ↵Anders Carlsson
correctly, giving them the correct arity. With this seemingly insignificant fix, we are now able to build and link clang using clang itself! (LLVM still has to be built with gcc for the time being). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91893 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-22Stop diagnosing the use of inner classes as friends. ddunbar asked whetherJohn McCall
this was useful, and on review Doug and I decided it was probably on the level of a bug in the standard and therefore not worth a warning even in -pedantic. If someone disagrees and urgently wants clang++ to warn about this in strict c++98 mode, we can talk about it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91868 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-22When converting from a type to itself or one of its base classes via aDouglas Gregor
constructor call, the conversion is only a standard conversion sequence if that constructor is a copy constructor. This fixes PR5834 in a semi-lame way, because the "real" fix will be to move over to InitializationSequence. That will happen "soonish", but not now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91861 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-21ARM: Honor -mfpu= and set __VFP_FP__ and __ARM_NEON__ "correctly".Daniel Dunbar
- Correctly is in quotes, because we are following what I interpreted as GCC's intent (which diverges from practice, naturally). - Also, fix the arch define for arm1136jf-s. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91855 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-21When a template-id refers to a single function template, and theDouglas Gregor
explicitly-specified template arguments are enough to determine the instantiation, and either template argument deduction fails or is not performed in that context, we can resolve the template-id down to a function template specialization (so sayeth C++0x [temp.arg.explicit]p3). Fixes PR5811. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91852 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-21Introduce an assertion to ensure that template argument deduction doesDouglas Gregor
not deduce an "overload" type. Such a deduction indicates a failure in semantic analysis (e.g., PR5811) that currently isn't caught until code-generation time. This assertions makes it clearer that this particular issue is a semantic-analysis problem, not a code-gen problem. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91844 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-21Improve on my previous fix for debug information. Rather thanDouglas Gregor
recursing in CGDebugInfo::CreateTypeNode, teach CanonicalizeTypeForDebugInfo---now called UnwrapTypeForDebugInfo---to keep unwrapping the type until we hit something that can be represented by debug information. Thanks to Anders for pointing this out! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91840 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-21Teach debug info generation to handle TemplateSpecializationType,Douglas Gregor
ElaboratedType, QualifiedNameType, and SubstTemplateTypeParmType type nodes. Also, produce an "unsupported" diagnostic for C++0x type nodes and "typeof" nodes, rather than asserting nondescriptly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91837 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-21Fix for PR5840: fix the kind of name lookup used for classes inEli Friedman
Sema::getTypeName. "LookupNestedNameSpecifierName" isn't quite the right kind of lookup, though; it doesn't ignore namespaces. Someone more familiar with the lookup code should fix this properly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91809 91177308-0d34-0410-b5e6-96231b3b80d8
