* kmp_omp.h -- OpenMP definition for kmp_omp_struct_info_t.
* This is for information about runtime library structures.
// The LLVM Compiler Infrastructure
// This file is dual licensed under the MIT and the University of Illinois Open
// Source Licenses. See LICENSE.txt for details.
* It should instead be modified in the OpenMP runtime and copied
* to the interface library code. This way we can minimize the
* problems that this is sure to cause having two copies of the
* same file.
* files live in libomp and libomp_db/src/include
* Before we release this to a customer, please don't change this value. After it is released and
* stable, then any new updates to the structures or data structure traversal algorithms need to
* change this value.
