Since the ICE message talks about the "backend", I wonder if this is an
indication that -fcoroutines-ts just isn't implemented for Mac OSX yet. (I'm on
OSX 10.11.6, but using an LLVM/Clang that was built from master.)
The following test case is extremely reduced.
====
cat > test.c <<EOF
void *f();
int main() {
void *coro = f();
__builtin_coro_resume(coro);
}
EOF
clang -fcoroutines-ts -c test.c
====
fatal error: error in backend: Cannot select: intrinsic %llvm.coro.resume
