This reverts commit f5033c37025db46df95a7859d7189d09b5e3433e.
revert this patch since it causes regressions for Tensile. A
reduced test case is:
int main()
{
std::shared_ptr<float> a;
a = std::shared_ptr<float>(
(float*)std::malloc(sizeof(float) * 100),
std::free
);
return 0;
}
Will fix the issue then re-commit.
Fixes: SWDEV-405317
D106463 caused a regression that prevents std::malloc to be
called in the device function, which is allowed with nvcc.
Basically the standard C++ header introducing malloc in
std namespace by using ::malloc. The device ::malloc
function needs to be declared before using ::malloc
to be introduced into std namespace.
Revert D106463 and add a test.

With this patch, OpenMP on AMDGCN will use the math functions
provided by ROCm ocml library. Linking device code to the ocml will be
done in the next patch.

This adds a very basic test in `cuda_with_openmp.cu` that just checks whether the CUDA & OpenMP integrated headers do compile, when a CUDA file is compiled with OpenMP (CPU) enabled.
Thus this basically adds the missing test for https://reviews.llvm.org/D90415.

This simply follows the scheme we have for other wrappers. It resolves
the current link problem, e.g., `__muldc3 not found`, when std::complex
operations are used on a device.
This will not allow complex make math function calls to work properly,
e.g., sin, but that is more complex (pan intended) anyway.

For OpenMP target regions to piggy back on the CUDA/AMDGPU/... implementation of math functions,
we include the appropriate definitions inside of an `omp begin/end declare variant match(device={arch(nvptx)})` scope.
This way, the vendor specific math functions will become specialized versions of the system math functions.
When a system math function is called and specialized version is available the selection logic introduced in D75779
instead call the specialized version. In contrast to the code path we used so far, the system header is actually included.
This means functions without specialized versions are available and so are macro definitions.
This should address PR42061, PR42798, and PR42799.

Summary:
This is a fix for the reported bug:
[[ https://bugs.llvm.org/show_bug.cgi?id=41861 | 41861 ]]
abs functions need to be moved under the c++ macro to avoid conflicts with included headers.
