+ * Removed hip automatic mode. Removes need for lib/Headers/cuda-open.
* Added aompExtractRegion script which will disassemble the amd gpu kernel.
+ * Fixes for having a barrier in sequential part of code region which is
+ * handled by the master warp. The fix extends the "barrier handshaking"
+ * between the master warp and worker warps. These 5 new deviceRTL
+ * functinos begin with __kmpc_amd_*. Only amdgcn uses these because
+ * nvptx uses a partial hardware barrier not availale in amdgcn.
+ * Ultimately, named_sync should never be called by amdgcn.
+ * Fix for reduction across teams.
