2011-10-10Now that we support move generation, mention this in the language extension ↵Sebastian Redl
and C++ status pages. Also update the C++ status for default functions, which are complete now that we can generate move functions, and destructor exception specifications, which I did a while ago. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141558 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-19Add list initialization for complex numbers in C. Essentially, this allows ↵Eli Friedman
"_Complex float x = {1.0f, 2.0f};". See changes to docs/LanguageExtensions.html for a longer description. <rdar://problem/9397672>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140090 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-08Allow C++0x enumerations with a fixed underlying type inDouglas Gregor
Objective-C. The @encode'ing of such an enumeration type is the same as its underlying type. <rdar://problem/5276348>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139297 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-08Implement the Objective-C 'instancetype' type, which is an alias ofDouglas Gregor
'id' that can be used (only!) via a contextual keyword as the result type of an Objective-C message send. 'instancetype' then gives the method a related result type, which we have already been inferring for a variety of methods (new, alloc, init, self, retain). Addresses <rdar://problem/9267640>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139275 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-29Add and document __has_feature values for the remaining C++0xDouglas Gregor
features, so clients can check for the availability of these features even before we get around to implementing them. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138741 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-09Thread Safety: Added basic argument parsing for all new attributes.Caitlin Sadowski
This patch special cases the parser for thread safety attributes so that all attribute arguments are put in the argument list (instead of a special parameter) since arguments may not otherwise resolve correctly without two-token lookahead. This patch also adds checks to make sure that attribute arguments are lockable objects. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137130 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-28Added basic parsing for all remaining attributes, thread safetyCaitlin Sadowski
analysis. This includes checking that the attributes are applied in the correct contexts and with the correct number of arguments. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@136383 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-23Fix a bunch of HTML compliance problems with LanguageExtensions.htmlSean Hunt
One weird thing is the addition of several <a name=""> tags where previously there were id attributes on the <h3> tags. This is because the id attribute must begin with a letter, not an underscore. The name attribute is not so constrained, so links will continue to work. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133677 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-23Revert "-fexceptions does not, in fact, enable C++ exceptions"Sean Hunt
In fact it does. For the driver anyway, and not cc1 which I'm supposed to pretend doesn't exist. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133673 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-15Automatic Reference Counting.John McCall
Language-design credit goes to a lot of people, but I particularly want to single out Blaine Garst and Patrick Beard for their contributions. Compiler implementation credit goes to Argyrios, Doug, Fariborz, and myself, in no particular order. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133103 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-11Implement Objective-C Related Result Type semantics.Douglas Gregor
Related result types apply Cocoa conventions to the type of message sends and property accesses to Objective-C methods that are known to always return objects whose type is the same as the type of the receiving class (or a subclass thereof), such as +alloc and -init. This tightens up static type safety for Objective-C, so that we now diagnose mistakes like this: t.m:4:10: warning: incompatible pointer types initializing 'NSSet *' with an expression of type 'NSArray *' [-Wincompatible-pointer-types] NSSet *array = [[NSArray alloc] init]; ^ ~~~~~~~~~~~~~~~~~~~~~~ /System/Library/Frameworks/Foundation.framework/Headers/NSObject.h:72:1: note: instance method 'init' is assumed to return an instance of its receiver type ('NSArray *') - (id)init; ^ It also means that we get decent type inference when writing code in Objective-C++0x: auto array = [[NSMutableArray alloc] initWithObjects:@"one", @"two",nil]; // ^ now infers NSMutableArray* rather than id git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@132868 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-21Audit and finish the implementation of C++0x nullptr, fixing twoDouglas Gregor
minor issues along the way: - Non-type template parameters of type 'std::nullptr_t' were not permitted. - We didn't properly introduce built-in operators for nullptr ==, !=, <, <=, >=, or > as candidate functions . To my knowledge, there's only one (minor but annoying) part of nullptr that hasn't been implemented: catching a thrown 'nullptr' as a pointer or pointer-to-member, per C++0x [except.handle]p4. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@131813 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-13Introduce __has_extension macroPeter Collingbourne
__has_extension is a function-like macro which takes the same set of feature identifiers as __has_feature. It evaluates to 1 if the feature is supported by Clang in the current language (either as a language extension or a standard language feature) or 0 if not. At the same time, add support for the C1X feature identifiers c_generic_selections (renamed from generic_selections) and c_static_assert, and document them. Patch by myself and Jean-Daniel Dupas. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@131308 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-11Implement CWG1170, which makes access-control errors into templateDouglas Gregor
argument deduction failures. Only implemented in C++0x, since this is a significant change in behavior from C++98/03. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@131209 91177308-0d34-0410-b5e6-96231b3b80d8

2011-04-15C1X: implement generic selectionsPeter Collingbourne
As an extension, generic selection support has been added for all supported languages. The syntax is the same as for C1X. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@129554 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-15Create __has_feature(cxx_noexcept) and mark it as working.Sebastian Redl
Find out that our C++0x status has only one field for noexcept expression and specification together, and that it was accidentally already marked as fully implemented. This completes noexcept specification work. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127701 91177308-0d34-0410-b5e6-96231b3b80d8

2011-01-25Add an attribute to forbid temporary instances of a type. This allows classJeffrey Yasskin
authors to write class __attribute__((forbid_temporaries)) Name { ... }; when they want to force users to name all variables of the type. This protects people from doing things like creating a scoped_lock that only lives for a single statement instead of an entire scope. The warning produced by this attribute can be disabled by -Wno-forbid-temporaries. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124217 91177308-0d34-0410-b5e6-96231b3b80d8
