libatomic isn't built for amdgcn but reduction-16.c adds it via -foffload=-latomic when offloading for nvptx is enabled. The following avoids linker errors when offloading to amdgcn is enabled as well. 2021-04-21 Richard Biener <rguenther@suse.de> libgomp/ * testsuite/libgomp.c-c++-common/reduction-16.c: Use -latomic only on nvptx-none.
