clang -std=c99 -fopenmp -fopenmp-targets=nvptx64-nvidia-cuda
opt/compiler-explorer/clang-trunk-20210804/lib/clang/14.0.0/include/__clang_cuda_device_functions.h:40:63:
error: use of undeclared identifier 'asm'
__DEVICE__ void __attribute__((overloadable)) __brkpt(void) { asm
volatile("brkpt;"); }

That would be because 'asm' is a gnu extension and I passed std=c99.
Clang accepts __asm or __asm__ when the header is included in openmp. As far as
I can tell, cuda accepts all three.</pre>
