071dca24 - [OpenMP] Require trivially copyable type for mapping

Sat, 07 Dec 2019 12:31:46 +0000

[OpenMP] Require trivially copyable type for mappingA trivially copyable type provides a trivial copy constructor and a trivialcopy assignment operator. This is enough for the runtime to memcpy the datato the device. Additionally there must be no virtual functions or virtualbase classes and the destructor is guaranteed to be trivial, ie performsno action.The runtime does not require trivial default constructors because on allocthe memory is undefined. Thus, weaken the warning to be only issued if themapped type is not trivially copyable.Differential Revision: https://reviews.llvm.org/D71134 List of files: /llvm-project-15.0.7/clang/test/OpenMP/distribute_parallel_for_private_messages.cpp

f07946e1 - [OPENMP]Fix PR39372: Does not complain about loop bound variable not

Mon, 29 Oct 2018 20:17:42 +0000

[OPENMP]Fix PR39372: Does not complain about loop bound variable notbeing shared.According to the standard, the variables with unspecified data-sharingattributes in presence of `default(none)` clause must be reported tousers. Compiler did not generate error reports for the variables used inother OpenMP regions. Patch fixes this.llvm-svn: 345533 List of files: /llvm-project-15.0.7/clang/test/OpenMP/distribute_parallel_for_private_messages.cpp

9925f156 - Resubmission of http://reviews.llvm.org/D21564 after fixes.

Mon, 27 Jun 2016 14:55:37 +0000

Resubmission of http://reviews.llvm.org/D21564 after fixes.[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 List of files: /llvm-project-15.0.7/clang/test/OpenMP/distribute_parallel_for_private_messages.cpp
