* [COFF, ARM64] Set the data type widths and the data layout stringMandeep Singh Grang2017-07-171-0/+88
| | | | | | | | | | | | | | Summary: COFF ARM64 is LLP64 platform. So int is 4 bytes, long is 4 bytes and long long is 8 bytes.

* [SystemZ] Add support for IBM z14 processor (3/3)Ulrich Weigand2017-07-174-19/+805
| | | | | | | | | | | | | | | This patch updates the vecintrin.h header file to provide the new set of high-level vector built-in functions. This matches the updated definition implemented by other compilers for the platform, indicated by the pre-defined macro __VEC__ == 10302. Note that some of the new functions (notably those involving the vector float data type) are only available with -march=z14 (indicated by __ARCH__ == 12). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@308199 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | This patch extends the -fzvector language feature to enable the new "vector float" data type when compiling at -march=z14.

* Keep the IdentifierInfo in the Token for alternative operator keywordOlivier Goffart2017-07-142-3/+13
| | | | | | | | | | | | | | | | | | | 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 Kumar2017-07-131-4/+11
| | | | | | | | | | | | | | | | | | | | | 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.

* [ObjC] Pick a 'readwrite' property when synthesizing ambiguousAlex Lorenz2017-07-133-1/+125
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | Summary: Generate more IntSymExpr constraints, perform SVal simplification for IntSymExpr and SymbolCast constraints, and create fully symbolic SymExprs Reviewers: zaks.anna, dcoughlin, NoQ, xazax.hun Subscribers: mgorny, cfe-commits Differential Revision: https://reviews.llvm.org/D28953 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@307833 91177308-0d34-0410-b5e6-96231b3b80d8
* [Driver] Update Fuchsia driver path handlingPetr Hosek2017-07-121-1/+2
| | | | | | | | | | | | | | | | | 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.

* [OPENMP] Emit implicit taskgroup block around taskloop directives.Alexey Bataev2017-07-122-2/+10
| | | | | | | | | If taskloop directive has no associated nogroup clause, it must emitted inside implicit taskgroup block. Runtime supports it, but we need to generate implicit taskgroup block explicitly to support future reductions codegen. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@307822 91177308-0d34-0410-b5e6-96231b3b80d8
