OpenMP Support in Clang
----------------------------------
-- ...
+- Clang gained basic support for OpenMP 4.5 offloading for NVPTX
target.
+ To compile your program for NVPTX target use the following options:
+ `-fopenmp -fopenmp-targets=nvptx64-nvidia-cuda` for 64 bit
platforms or
+ `-fopenmp -fopenmp-targets=nvptx-nvidia-cuda` for 32 bit platform.
+
+- Passing options to the OpenMP device offloading toolchain can be
done using
+ the `-Xopenmp-target=<triple> -opt=val` flag. In this way the
`-opt=val`
+ option will be forwarded to the respective OpenMP device offloading
toolchain
+ described by the triple. For example passing the compute capability
to
+ the OpenMP NVPTX offloading toolchain can be done as follows:
+ `-Xopenmp-target=nvptx62-nvidia-cuda -march=sm_60`.
Is that a typo and should say "nvptx64"?
