+// NVPTX:  @_ZZ2dfvE4s_ec = internal addrspace(3) global %struct.EC zeroinitializer
+// AMDGCN: @_ZZ2dfvE4s_ec = internal addrspace(3) global %struct.EC undef
----------------
Hmm. __shared__ should not be initialized in NVPTX either. This looks like a bug in NVPTX. 

For now you should make shared uninitialized regardless of whether we're compiling for AMDGCN or NVPTX.
