Tobias, can you try on powerpc?
Testcase now compiles and runs w/o error message.

I guess the normal answer would be use libatomic, but it isn't ported for
nvptx.
I guess at least temporarily this is ok,though I'm wondering why
you need __sync_*_16 rather than __atomic_*_16, or perhaps both __sync_* and
__atomic_*.
What happens if you try
unsigned __int128 v;
...
I had to change "unsigned __int128" and "unsigned __int128v" to
"__uint128_t" and "expected" to "exp". Result without offloading
configured on x86-64-gnu-linux:
aotmic.c:(.text+0x84): undefined reference to `__atomic_fetch_add_16'
/usr/bin/ld: aotmic.c:(.text+0xa3): undefined reference to
`__atomic_fetch_add_16'
/usr/bin/ld: aotmic.c:(.text+0xda): undefined reference to
`__atomic_compare_exchange_16'
And on PowerPC with nvptx (without the RFC patch):
atomic.c: In function 'main._omp_fn.0':
atomic.c:6:11: internal compiler error: in write_fn_proto, at
config/nvptx/nvptx.c:913
