| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace inheriting constructors implementation with new approach, voted into C++ last year as a DR against C++11. Instead of synthesizing a set of derived class constructors for each inherited base class constructor, we make the constructors of the base class visible to constructor lookup in the derived class, using the normal rules for using-declarations. For constructors, UsingShadowDecl now has a ConstructorUsingShadowDecl derived class that tracks the requisite additional information. We create shadow constructors (not found by name lookup) in the derived class to model the actual initialization, and have a new expression node, CXXInheritedCtorInitExpr, to model the initialization of a base class from such a constructor. (This initialization is special because it performs real perfect forwarding of arguments.) In cases where argument forwarding is not possible (for inalloca calls, variadic calls, and calls with callee parameter cleanup), the shadow inheriting constructor is not emitted and instead we directly emit the initialization code into the caller of the inherited constructor. Note that this new model is not perfectly compatible with the old model in some corner cases. In particular: * if B inherits a private constructor from A, and C uses that constructor to construct a B, then we previously required that A befriends B and B befriends C, but the new rules require A to befriend C directly, and * if a derived class has its own constructors (and so its implicit default constructor is suppressed), it may still inherit a default constructor from a base class git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@274049 91177308-0d34-0410-b5e6-96231b3b80d8

* Add loop pragma for Loop DistributionAdam Nemet2016-06-141-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This is similar to other loop pragmas like 'vectorize'. Currently it only has state values: distribute(enable) and distribute(disable). When one of these is specified the corresponding loop metadata is generated: !{!"llvm.loop.distribute.enable", i1 true/false} As a result, loop distribution will be attempted on the loop even if Loop Distribution in not enabled globally. Analogously, with 'disable' distribution can be turned off for an individual loop even when the pass is otherwise enabled. There are some slight differences compared to the existing loop pragmas. 1. There is no 'assume_safety' variant which makes its handling slightly different from 'vectorize'/'interleave'. 2. Unlike the existing loop pragmas, it does not have a corresponding numeric pragma like 'vectorize' -> 'vectorize_width'. So for the consistency checks in CheckForIncompatibleAttributes we don't need to check it against other pragmas. We just need to check for duplicates of the same pragma.

* Clang support for __is_assignable intrinsicDavid Majnemer2016-05-232-0/+2
| | | | | | | | | | | | | | | | | | | MSVC now supports the __is_assignable type trait intrinsic, to enable easier and more efficient implementation of the Standard Library's is_assignable trait. As of Visual Studio 2015 Update 3, the VC Standard Library implementation uses the new intrinsic unconditionally. The implementation is pretty straightforward due to the previously existing is_nothrow_assignable and is_trivially_assignable. We handle __is_assignable via the same code as the other two except that we skip the extra checks for nothrow or triviality. Patch by Dave Bartolomeo!

* Fix a bug involving deferred decl emission and PCHReid Kleckner2016-04-222-0/+18
| | | | | | | | | | | | | | | | For various reasons, involving dllexport and class linkage compuations, we have to wait until after the semicolon after a class declaration to emit inline methods. These are "deferred" decls. Before this change, finishing the tag decl would trigger us to deserialize some PCH so that we could make a "pretty" IR-level type. Deserializing the PCH triggered calls to HandleTopLevelDecl, which, when done, checked the deferred decl list, and emitted some dllexported decls that weren't ready. Avoid this re-entrancy. Deferred decls should not get emitted when a tag is finished, they should only be emitted after a real top level decl in the main file. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@267186 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | exactly the same as clang's existing [[clang::fallthrough]] attribute, which has been updated to have the same semantics. The one significant difference is that [[fallthrough]] is ill-formed if it's not used immediately before a switch label (even when -Wimplicit-fallthrough is disabled). To support that, we now build a CFG of any function that uses a '[[fallthrough]];' statement to check.

| | | | | | | | | | | | | | | | | | | By storing the instantiated expression back in the ParmVarDecl, we remove the last need for separately storing the sub-expression of a CXXDefaultArgExpr. This makes PCH/Modules merging quite simple: CXXDefaultArgExpr records are serialized as references to the ParmVarDecl, and we ignore redundant attempts to overwrite the instantiated expression. This has some extremely marginal impact on user-facing semantics. However, the major effect is that it avoids IRGen errors about conflicting definitions due to lambdas in the argument being instantiated multiple times while sharing the same mangling. It should also slightly improve memory usage and module file size. rdar://23810407 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@256983 91177308-0d34-0410-b5e6-96231b3b80d8

* Stop back-patching 'readonly' Objective-C properties with 'readwrite' ones.Douglas Gregor2015-11-031-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A 'readonly' Objective-C property declared in the primary class can effectively be shadowed by a 'readwrite' property declared within an extension of that class, so long as the types and attributes of the two property declarations are compatible. Previously, this functionality was implemented by back-patching the original 'readonly' property to make it 'readwrite', destroying source information and causing some hideously redundant, incorrect code. Simplify the implementation to express how this should actually be modeled: as a separate property declaration in the extension that shadows (via the name lookup rules) the declaration in the primary class. While here, correct some broken Fix-Its, eliminate a pile of redundant code, clean up the ARC migrator's handling of properties declared in extensions, and fix debug info's naming of methods that come from categories. A wonderous side effect of doing this write is that it eliminates the "AddedObjCPropertyInClassExtension" method from the AST mutation listener, which in turn eliminates the last place where we rewrite entire declarations in a chained PCH file or a module file. This change (which fixes rdar://problem/18475765) will allow us to eliminate the rewritten-decls logic from the serialization library, and fixes a crash (rdar://problem/23247794) illustrated by the test/PCH/chain-categories.m example. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@251874 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove bad test.Sean Silva2015-07-302-15/+0
| | | | | | | | | | | | | We currently don't canonicalize paths in the preprocessed files. But we do when writing to PCH. This causes a discrepancy on Windows with the test below. This test fails even on unix if you change the test to use `%S//preprocess.h`. I am led to conclude that the invariant that this test was intending to test has not been upheld for a while (and may never have been). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@243602 91177308-0d34-0410-b5e6-96231b3b80d8

* [Sema] Emit a better diagnostic when variable redeclarations disagreeDavid Majnemer2015-07-141-2/+2
| | | | | | | | | | | We referred to all declaration in definitions in our diagnostic messages which is can be inaccurate. Instead, classify the declaration and emit an appropriate diagnostic for the new declaration and an appropriate note pointing to the old one.
