*	[CUDA][HIP] Fix host/device check with -fopenmp	Yaxun Liu	2019-10-09	1	-1/+6
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	CUDA/HIP program may be compiled with -fopenmp. In this case, -fopenmp is only passed to host compilation to take advantages of multi-threads computation. CUDA/HIP and OpenMP both use Sema::DeviceCallGraph to store functions to be analyzed and remove them once they decide the function is sure to be emitted. CUDA/HIP and OpenMP have different functions to determine if a function is sure to be emitted. To check host/device correctly for CUDA/HIP when -fopenmp is enabled, there needs a unified logic to determine whether a function is to be emitted. The logic needs to be aware of both CUDA and OpenMP logic. Differential Revision: https://reviews.llvm.org/D67837 llvm-svn: 374263
*	[CUDA] Make unattributed constexpr functions implicitly host+device.	Justin Lebar	2016-03-30	1	-0/+69
	With this patch, by a constexpr function is implicitly host+device unless: a) it's a variadic function (variadic functions are not allowed on the device side), or b) it's preceeded by a __device__ overload in a system header. The restriction on overloading __host__ __device__ functions on the basis of their CUDA attributes remains in place, but we use (b) to allow us to define __device__ overloads for constexpr functions in cmath, which would otherwise be __host__ __device__ and thus not overloadable. You can disable this behavior with -fno-cuda-host-device-constexpr. Reviewers: tra, rnk, rsmith Subscribers: cfe-commits Differential Revision: http://reviews.llvm.org/D18380 llvm-svn: 264964
