* Try to fix modules buildMatthias Braun2017-07-151-0/+1
| | | | | | | | | | | | Module builds somehow report an ambiguity between clang::Diagnostic and clang::Tooling::Diagnostic. It seems as if one of the additional headers brought in by the module brings the clang namespace to the toplevel. I could not find out the reason for that, so for now I go with the simple fix to bring the build back to green. rdar://33321397 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@308071 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | There was already a returns_localized_nsstring annotation to indicate that the return value could be passed to UIKit methods that would display them. However, those UIKit methods were hard-coded, and it was not possible to indicate that other classes/methods in a code-base would do the same. The takes_localized_nsstring annotation can be put on function parameters and selector parameters to indicate that those will also show the string to the user.

* Keep the IdentifierInfo in the Token for alternative operator keywordOlivier Goffart2017-07-147-57/+61
| | | | | | | | | | | | | | | | | | | The goal of this commit is to fix clang-format so it does not merge tokens when using the alternative spelling keywords. (eg: "not foo" should not become "notfoo") The problem is that Preprocessor::HandleIdentifier used to drop the identifier info from the token for these keyword. This means the first condition of TokenAnnotator::spaceRequiredBefore is not met. We could add explicit check for the spelling in that condition, but I think it is better to keep the IdentifierInfo and handle the operator keyword explicitly when needed. That actually leads to simpler code, and probably slightly more efficient as well. Another side effect of this change is that __identifier(and) will now work as one would expect, removing a FIXME from the MicrosoftExtensions.cpp test Differential Revision: https://reviews.llvm.org/D35172 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@308008 91177308-0d34-0410-b5e6-96231b3b80d8

* [ubsan] Teach the pointer overflow check that "p - <unsigned> <= p" (PR33430)Vedant Kumar2017-07-134-20/+44
| | | | | | | | | | | | | | | | | | | | | The pointer overflow check gives false negatives when dealing with expressions in which an unsigned value is subtracted from a pointer. This is summarized in PR33430 [1]: ubsan permits the result of the subtraction to be greater than "p", but it should not. To fix the issue, we should track whether or not the pointer expression is a subtraction. If it is, and the indices are unsigned, we know to expect "p - <unsigned> <= p". I've tested this by running check-{llvm,clang} with a stage2 ubsan-enabled build. I've also added some tests to compiler-rt, which are in D34122.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | property and check for incompatible attributes This commit changes the way ambiguous property synthesis (i.e. when synthesizing a property that's declared in multiple protocols) is performed. Previously, Clang synthesized the first property that was found. This lead to problems when the property was synthesized in a class that conformed to two protocols that declared that property and a second protocols had a 'readwrite' declaration - the setter was not synthesized so the class didn't really conform to the second protocol and user's code would crash at runtime when they would try to set the property. This commit ensures that a first readwrite property is selected. This is a semantic change that changes users code in this manner: ``` @protocol P @property(readonly) int p; @end @protocol P2 @property(readwrite) id p; @end @interface I <P2> @end @implementation I @syntesize p; // Users previously got a warning here, and Clang synthesized // readonly 'int p' here. Now Clang synthesizes readwrite 'id' p.. @end ``` To ensure that this change is safe, the warning about incompatible types is promoted to an error when this kind of readonly/readwrite ambiguity is detected in the @implementation. This will ensure that previous code that had this subtle bug and ignored the warning now will fail to compile with an error, and users should not get suprises at runtime once they resolve the error. The commit also extends the ambiguity checker, and now it can detect conflicts among the different property attributes. An error diagnostic is used for conflicting attributes, to ensure that the user won't get "suprises" at runtime. ProtocolPropertyMap is removed in favour of a a set + vector because the map's order of iteration is non-deterministic, so it couldn't be used to select the readwrite property. rdar://31579994 Differential Revision: https://reviews.llvm.org/D35268 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@307903 91177308-0d34-0410-b5e6-96231b3b80d8

* Reland "[Driver] Update Fuchsia driver path handling"Petr Hosek2017-07-124-20/+86
| | | | | | | | | | | | | | | | | Several improvements to the Fuchsia driver: * Search for C++ library headers and libraries in directories that are part of the toolchain distribution rather than sysroot. * Use LLVM support utlities to construct paths to make sure the driver is also usable on Windows for cross-compiling. * Change the driver to inherit directly from ToolChain rather than Generic_GCC since we don't need any of the GCC related multilib logic.

* [index] Don't add relation to a NamedDecl with no nameBen Langmuir2017-07-122-5/+22
| | | | | | | | | | | | Unless it's one of the special cases (tag, category) that we can handle. This syncs up the check between handling a decl and handling a relation. This would cause invalid nameless decls to end up in relations despite having no name or USR. rdar://problem/32474406 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@307855 91177308-0d34-0410-b5e6-96231b3b80d8
