* [OpenMP] Support for the if-clause on the combined directive 'target parallel'.Arpith Chacko Jacob2017-01-181-0/+1
| | | | | | | | | | | | | | | | | | | | | | | The if-clause on the combined directive potentially applies to both the 'target' and the 'parallel' regions. Codegen'ing the if-clause on the combined directive requires additional support because the expression in the clause must be captured by the 'target' capture statement but not the 'parallel' capture statement. Note that this situation arises for other clauses such as num_threads. The OMPIfClause class inherits OMPClauseWithPreInit to support capturing of expressions in the clause. A member CaptureRegion is added to OMPClauseWithPreInit to indicate which captured statement (in this case 'target' but not 'parallel') captures these expressions. To ensure correct codegen of captured expressions in the presence of combined 'target' directives, OMPParallelScope was added to 'parallel' codegen.

| | | | | | | | | | | | | | | | | | | | initialization of each array element: * ArrayInitLoopExpr is a prvalue of array type with two subexpressions: a common expression (an OpaqueValueExpr) that represents the up-front computation of the source of the initialization, and a subexpression representing a per-element initializer * ArrayInitIndexExpr is a prvalue of type size_t representing the current position in the loop This will be used to replace the creation of explicit index variables in lambda capture of arrays and copy/move construction of classes with array elements, and also C++17 structured bindings of arrays by value (which inexplicably allow copying an array by value, unlike all of C++'s other array declarations). No uses of these nodes are introduced by this change, however. llvm-svn: 289413

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 llvm-svn: 274049

| | | | | | | | | | | | | [OpenMP] Initial implementation of parse and sema for composite pragma 'distribute parallel for' This patch is an initial implementation for #distribute parallel for. The main differences that affect other pragmas are: The implementation of 'distribute parallel for' requires blocking of the associated loop, where blocks are "distributed" to different teams and iterations within each block are scheduled to parallel threads within each team. To implement blocking, sema creates two additional worksharing directive fields that are used to pass the team assigned block lower and upper bounds through the outlined function resulting from 'parallel'. In this way, scheduling for 'for' to threads can use those bounds. As a consequence of blocking, the stride of 'distribute' is not 1 but it is equal to the blocking size. This is returned by the runtime and sema prepares a DistIncrExpr variable to hold that value. As a consequence of blocking, the global upper bound (EnsureUpperBound) expression of the 'for' is not the original loop upper bound (e.g. in for(i = 0 ; i < N; i++) this is 'N') but it is the team-assigned block upper bound. Sema creates a new expression holding the calculation of the actual upper bound for 'for' as UB = min(UB, PrevUB), where UB is the loop upper bound, and PrevUB is the team-assigned block upper bound. llvm-svn: 273884

| | | | | | | | | | | | | | | | | | | classes. MSVC actively uses unqualified lookup in dependent bases, lookup at the instantiation point (non-dependent names may be resolved on things declared later) etc. and all this stuff is the main cause of incompatibility between clang and MSVC. Clang tries to emulate MSVC behavior but it may fail in many cases. clang could store lexed tokens for member functions definitions within ClassTemplateDecl for later parsing during template instantiation. It will allow resolving many possible issues with lookup in dependent base classes and removing many already existing MSVC-specific hacks/workarounds from the clang code. llvm-svn: 272774

* [Cxx1z] Implement Lambda Capture of *this by Value as [=,*this] (P0018R3)Faisal Vali2016-03-211-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement lambda capture of *this by copy. For e.g.: struct A { int d = 10; auto foo() { return [*this] (auto a) mutable { d+=a; return d; }; } }; auto L = A{}.foo(); // A{}'s lifetime is gone. // Below is still ok, because *this was captured by value. assert(L(10) == 20); assert(L(100) == 120); If the capture was implicit, or [this] (i.e. *this was captured by reference), this code would be otherwise undefined. Implementation Strategy: - amend the parser to accept *this in the lambda introducer - add a new king of capture LCK_StarThis - teach Sema::CheckCXXThisCapture to handle by copy captures of the enclosing object (i.e. *this) - when CheckCXXThisCapture does capture by copy, the corresponding initializer expression for the closure's data member direct-initializes it thus making a copy of '*this'. - in codegen, when assigning to CXXThisValue, if *this was captured by copy, make sure it points to the corresponding field member, and not, unlike when captured by reference, what the field member points to. - mark feature as implemented in svn Much gratitude to Richard Smith for his carefully illuminating reviews! llvm-svn: 263921
