[OpenMP] Sema and parsing for 'target teams distribute simd’ pragma This patch is to implement sema and parsing for 'target teams distribute simd’ pragma. Differential Revision: https://reviews.llvm.org/D28252 llvm-svn: 291579
2017-01-11 02:08:18 +08:00
// RUN: %clang_cc1 -verify -fopenmp %s
// RUN: %clang_cc1 -verify -fopenmp -std=c++98 %s
// RUN: %clang_cc1 -verify -fopenmp -std=c++11 %s
[OPENMP] Support for -fopenmp-simd option with compilation of simd loops only. Added support for -fopenmp-simd option that allows compilation of simd-based constructs without emission of OpenMP runtime calls. llvm-svn: 321560
