* Revert r142914 and r142915, due to possibly missing file.NAKAMURA Takumi2011-10-251-12/+44
| | | | | | r142914: "Introduce a placeholder type for "pseudo object"" r142915: "Pull the pseudo-object stuff into its own file." llvm-svn: 142921
* Introduce a placeholder type for "pseudo object"John McCall2011-10-251-44/+12
| | | | | | | | | | | | | | | 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. llvm-svn: 142914

* Change operator<< for raw_ostream and NamedDecl to take a reference instead ↵Benjamin Kramer2011-10-141-1/+1

* Catch placeholder types in DefaultLvalueConversionJohn McCall2011-10-111-28/+45
| | | | | | | | | | | 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. llvm-svn: 141738

| | | | | | | | | conversion function whose result type is an lvalue reference. The initialization code already handled this properly, but overload resolution was allowing the binding. Fixes PR11003 / <rdar://problem/10233078>. llvm-svn: 141137

| | | | | | | 'bool' rather than '_Bool' within types, to make things a bit more readable. Fixes <rdar://problem/10063263>. llvm-svn: 140650
* Rename Diagnostic to DiagnosticsEngine as per issue 5397David Blaikie2011-09-251-2/+3
| | | | llvm-svn: 140478
* Add a special note for overload resolution when an initializer list argumentSebastian Redl2011-09-241-0/+11
| | | | | | | | | 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. llvm-svn: 140461
* Give InitListChecker a verification-only mode, where it neither emits ↵Sebastian Redl2011-09-241-15/+19
| | | | | | | | | | | 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. llvm-svn: 140457
* Removing a bunch of dead returns/breaks after llvm_unreachables.David Blaikie2011-09-231-2/+0

* In Microsoft mode(-fms-compatibility), prefer an integral conversion to a ↵Francois Pichet2011-09-181-0/+19
| | | | | | | | | | | | | | | | 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. llvm-svn: 140007
* Rename LangOptions::Microsoft to LangOptions::MicrosoftExt to make it clear ↵Francois Pichet2011-09-171-3/+3
| | | | | | | | 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. llvm-svn: 139987

* Contextually converting to 'id' is not a useful operation. ContextuallyJohn McCall2011-09-091-14/+46
| | | | | | | | | | | | 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. llvm-svn: 139354
* Give conversions of block pointers to ObjC pointers a different cast kindJohn McCall2011-09-091-6/+13
| | | | | | | | 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. llvm-svn: 139352
* In Microsoft mode, if we are inside a template class member function and we ↵Francois Pichet2011-09-071-1/+14
| | | | | | | | 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. llvm-svn: 139210
* Be sure to emit lvalue-to-rvalue casts for loads from x-values.John McCall2011-08-301-4/+4
| | | | | | | Doing this happens to disrupt the pattern that ARC was looking for for move optimizations, so we need to fix that simultaneously. llvm-svn: 138789
