[OpenMP] Ensure testing for versions 4.5 and default - Part 3 This third patch in the series removes version 5.0 string from test cases making them check for default version. It also add test cases for version 4.5. Reviewed By: ABataev Differential Revision: https://reviews.llvm.org/D85214
2020-08-28 03:35:36 +08:00
// RUN: %clang_cc1 -verify -fopenmp %s -Wuninitialized
[OPENMP50]Add if clause in distribute simd directive. According to OpenMP 5.0, if clause can be used in for simd directive. If condition in the if clause if false, the non-vectorized version of the loop must be executed.
