2012-04-05[Lex] Add support for 'user specified system frameworks' (see test case).Daniel Dunbar

2012-04-03Correct handling of _Pragma macro inside a macro argument.Argyrios Kyrtzidis
If we are pre-expanding a macro argument don't actually "activate" the pragma at that point, activate the pragma whenever we encounter it again in the token stream. This ensures that we will activate it in the correct location or that we will ignore it if it never enters the token stream, e.g: \#define EMPTY(x) \#define INACTIVE(x) EMPTY(x) INACTIVE(_Pragma("clang diagnostic ignored \"-Wconversion\"")) This also fixes the crash in rdar://11168596. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153959 91177308-0d34-0410-b5e6-96231b3b80d8

We want the macro expansions to be considered as before-in-translation-unit for everything in the included file. -In the preprocessing record take into account that only inclusion directives can be encountered as "out-of-order" (by comparing the start of the range which for inclusions is the hash location) and use binary search if there is an extreme number of macro expansions in the include directive.

2012-03-16From Vassil Vassilev:Axel Naumann
Enable incremental parsing by the Preprocessor, where more code can be provided after an EOF. It mainly prevents the tearing down of the topmost lexer. To be used like this: PP.enableIncrementalProcessing(); while (getMoreSource()) { while (Parser.ParseTopLevelDecl(ADecl)) {...} } PP.enableIncrementalProcessing(false); git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152914 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-09Improve diagnostics for UCNs referring to control characters and members of theRichard Smith
basic source character set in C++98. Add -Wc++98-compat diagnostics for same in literals in C++11. Extend such support to cover string literals as well as character literals, and mark N2170 as done. This seems too minor to warrant a release note to me. Let me know if you disagree. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152444 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-08Implement C++11 [lex.ext]p10 for string and character literals: a ud-suffix notRichard Smith
starting with an underscore is ill-formed. Since this rule rejects programs that were using <inttypes.h>'s macros, recover from this error by treating the ud-suffix as a separate preprocessing-token, with a DefaultError ExtWarn. The approach of treating such cases as two tokens is under discussion for standardization, but is in any case a conforming extension and allows existing codebases to keep building while the committee makes up its mind. Reword the warning on the definition of literal operators not starting with underscores (which are, strangely, legal) to more explicitly state that such operators can't be called by literals. Remove the special-case diagnostic for hexfloats, since it was both triggering in the wrong cases and incorrect. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152287 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-06Add clang support for new Objective-C literal syntax for NSDictionary, NSArray,Ted Kremenek
NSNumber, and boolean literals. This includes both Sema and Codegen support. Included is also support for new Objective-C container subscripting. My apologies for the large patch. It was very difficult to break apart. The patch introduces changes to the driver as well to cause clang to link in additional runtime support when needed to support the new language features. Docs are forthcoming to document the implementation and behavior of these features. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152137 91177308-0d34-0410-b5e6-96231b3b80d8

grammar requires a string-literal and not a user-defined-string-literal. The two constructs are still represented by the same TokenKind, in order to prevent a combinatorial explosion of different kinds of token. A flag on Token tracks whether a ud-suffix is present, in order to prevent clients from needing to look at the token's spelling. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152098 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-24Implement a new type trait __is_trivially_constructible(T, Args...)Douglas Gregor
that provides the behavior of the C++11 library trait std::is_trivially_constructible<T, Args...>, which can't be implemented purely as a library. Since __is_trivially_constructible can have zero or more arguments, I needed to add Yet Another Type Trait Expression Class, this one handling arbitrary arguments.
