[Clang] Fix sema checks thinking kernels aren't kernels (#104460) 2024-08-16T23:36:27+00:00 Joseph Huber huberjn@outlook.com 2024-08-16T23:36:27+00:00 e169cc162adbe89d498e774bccf4e228af989849 Summary: Currently we have some sema checks to make sure users don't apply kernel-only attributes to non-kernel functions. However, this currently did not correctly check for bare NVPTX / AMDGPU kernel attributes, making it impossible to use them at all w/o CUDA enabled. This patch fixes that by checking for the calling convention / attributes directly.

 [CodeGenCXX] Convert some tests to opaque pointers (NFC) 2022-10-06T10:22:03+00:00 Nikita Popov npopov@redhat.com 2022-10-06T10:12:57+00:00 1b9a6e58a8b831193c9e5e733f881aabe0d2d06b Conversion done using the script at https://gist.github.com/nikic/98357b71fd67756b0f064c9517b62a34. These are tests where the conversion worked out of the box and no manual fixup was performed.

[amdgpu] Add amdgpu_kernel calling conv attribute to clang 2022-05-20T07:50:37+00:00 Jon Chesterfield jonathanchesterfield@gmail.com 2022-05-20T07:50:36+00:00 83c431fb9e72abbd2eddf26388245eb4963370e2 Allows emitting define amdgpu_kernel void @func() IR from C or C++. This replaces the current workflow which is to write a stub in opencl that calls an external C function implemented in C++ combined through llvm-link. Calling the resulting function still requires a manual implementation of the ABI from the host side. The primary application is for more rapid debugging of the amdgpu backend by permuting a C or C++ test file instead of manually updating an IR file. Implementation closely follows D54425.
