2011-11-10Implicit casts from rvalue to lvalue are not meaningful. Don't accidentally addRichard Smith
them when performing a const conversion on the implicit object argument for a member operator call on an rvalue. No change to the testsuite: the test for this change is that the added assertion does not fire any more. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144333 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-25Introduce a placeholder type for "pseudo object"John McCall
expressions: expressions which refer to a logical rather than a physical l-value, where the logical object is actually accessed via custom getter/setter code. A subsequent patch will generalize the AST for these so that arbitrary "implementing" sub-expressions can be provided. Right now the only client is ObjC properties, but this should be generalizable to similar language features, e.g. Managed C++'s __property methods. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142914 91177308-0d34-0410-b5e6-96231b3b80d8

and DefaultFunctionArrayLvalueConversion. To prevent significant regression for should-this-be-a-call fixits, and to repair some such regression from the introduction of bound member placeholders, make those placeholder checks try to build calls appropriately. Harden the build-a-call logic while we're at it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141738 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-24Add a special note for overload resolution when an initializer list argumentSebastian Redl
cannot be converted. This is in preparation for overload resolution of initializer lists. Currently, you will always get this message when you try to pass an init list to an overloaded function. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140461 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-24Give InitListChecker a verification-only mode, where it neither emits ↵Sebastian Redl
diagnostics nor builds a semantic (structured) initializer list, just reports on whether it can match the given list to the target type. Use this mode for doing init list checking in the initial step of initialization, which will eventually allow us to do overload resolution based on the outcome. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140457 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-18In Microsoft mode(-fms-compatibility), prefer an integral conversion to a ↵Francois Pichet
floating-to-integral conversion if the integral conversion is between types of the same size. For example: void f(float); void f(int); int main { long a; f(a); } Here, MSVC will call f(int) instead of generating a compile error as clang will do in standard mode. This fixes a few errors when parsing MFC code with clang. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140007 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-17Rename LangOptions::Microsoft to LangOptions::MicrosoftExt to make it clear ↵Francois Pichet
that this flag must be used only for Microsoft extensions and not emulation; to avoid confusion with the new LangOptions::MicrosoftMode flag. Many of the code now under LangOptions::MicrosoftExt will eventually be moved under the LangOptions::MicrosoftMode flag. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139987 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-09Contextually converting to 'id' is not a useful operation. ContextuallyJohn McCall
converting to an arbitrary Objective-C pointer type is. Without significantly re-implementing anything, change the API to reflect this, and as a minor optimization, strip the pointer conversion off before potentially building it. Mostly, this removes a really bizarre-looking bit of code from BuildInstanceMessage. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139354 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-09Give conversions of block pointers to ObjC pointers a different cast kindJohn McCall
than conversions of C pointers to ObjC pointers. In order to ensure that we've caught every case, add asserts to CastExpr that strictly determine which cast kind is used for which kind of bit cast. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139352 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-07In Microsoft mode, if we are inside a template class member function and we ↵Francois Pichet
can't resolve a function call then create a type-dependent CallExpr even if the function has no type dependent arguments. The goal is to postpone name lookup to instantiation time to be able to search into type dependent base classes. With this patch in, clang will generate only 37 errors (down from 212) when parsing a typical MFC source file. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139210 91177308-0d34-0410-b5e6-96231b3b80d8
