2012-08-13When the header file search resolves a quoted include to a file in theDouglas Gregor
current directory, propagate the framework and in-index-header-map from the including header's information down to the included header's information. Fixes <rdar://problem/11261291>. As with everything header-map related, we can't really test this in isolation within Clang, so it's tested elsewhere. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@161759 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-24Add __has_feature(attribute_availability_with_message).Jordan Rose
This tests for the ability to include a "message" field in availability attributes, like so: extern void ATSFontGetName(const char *oName) __attribute__((availability(macosx,introduced=8.0,deprecated=9.0, message="use CTFontCopyFullName"))); This was actually supported in Clang 3.1, but we got a request for a __has_feature so that header files can use this more safely. It's unfortunate that the 3.1 release doesn't include this, however. <rdar://problem/11886458> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160699 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-20Introduce ObjCRuntime::hasWeakClassImport() and use it in the appropriateJohn McCall
places. I've turned this off for the GNU runtimes --- I don't know if they support weak class import, but it's easy enough for them to opt in. Also tweak a comment per review by Jordan. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158860 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-20Restructure how the driver communicates information about theJohn McCall
target Objective-C runtime down to the frontend: break this down into a single target runtime kind and version, and compute all the relevant information from that. This makes it relatively painless to add support for new runtimes to the compiler. Make the new -cc1 flag, -fobjc-runtime=blah-x.y.z, available at the driver level as a better and more general alternative to -fgnu-runtime and -fnext-runtime. This new concept of an Objective-C runtime also encompasses what we were previously separating out as the "Objective-C ABI", so fragile vs. non-fragile runtimes are now really modelled as different kinds of runtime, paving the way for better overall differentiation. As a sort of special case, continue to accept the -cc1 flag -fobjc-runtime-has-weak, as a sop to PLCompatibilityWeak. I won't go so far as to say "no functionality change", even ignoring the new driver flag, but subtle changes in driver semantics are almost certainly not intended. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158793 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-19Revert predefined decl tracking.Meador Inge
r158085 added some logic to track predefined declarations. The main reason we had predefined declarations in the input was because the __builtin_va_list declarations were injected into the preprocessor input. As of r158592 we explicitly build the __builtin_va_list declarations. Therefore the predefined decl tracking is no longer needed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158732 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-19Improve the specification of spellings in Attr.td.Sean Hunt
Note that this is mostly a structural patch that handles the change from the old spelling style to the new one. One consequence of this is that all AT_foo_bar enum values have changed to not be based off of the first spelling, but rather off of the class name, so they are now AT_FooBar and the like (a straw poll on IRC showed support for this). Apologies for code churn. Most attributes have GNU spellings as a temporary solution until everything else is sorted out (such as a Keyword spelling, which I intend to add if someone else doesn't beat me to it). This is definitely a WIP. I've also killed BaseCheckAttr since it was unused, and I had to go through every attribute anyway. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158700 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-15PR12717: Clang supports hexadecimal floating-point literals in all languageRichard Smith
modes. For languages other than C99/C11, this isn't quite a conforming extension, and for C++11, it breaks some reasonable code containing user-defined literals. In languages which don't officially have hexfloats, pare back this extension to only apply in cases where the token starts 0x and does not contain an underscore. The extension is still not quite conforming, but it's a lot closer now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158487 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-08Disable _Pragma during HTML macro rewriting to keep from crashing.Jordan Rose
The preprocessor's handling of diagnostic push/pops is stateful, so encountering pragmas during a re-parse causes problems. HTMLRewrite already filters out normal # directives including #pragma, so it's clear it's not expected to be interpreting pragmas in this mode. This fix adds a flag to Preprocessor to explicitly disable pragmas. The "right" fix might be to separate pragma lexing from pragma parsing so that we can throw away pragmas like we do preprocessor directives, but right now it's important to get the fix in. Note that this has nothing to do with the "hack" of re-using the input preprocessor in HTMLRewrite. Even if we someday copy the preprocessor instead of re-using it, the copy would (and should) include the diagnostic level tables and have the same problems. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158214 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-06Add pedantic warning -Wempty-translation-unit (C11 6.9p1).Jordan Rose
In standard C since C89, a 'translation-unit' is syntactically defined to have at least one "external-declaration", which is either a decl or a function definition. In Clang the latter gives us a declaration as well. The tricky bit about this warning is that our predefines can contain external declarations (__builtin_va_list and the 128-bit integer types). Therefore our AST parser now makes sure we have at least one declaration that doesn't come from the predefines buffer. Also, remove bogus warning about empty source files. This doesn't catch source files that only contain comments, and never fired anyway because of our predefines.
