1 // Check that types, widths, __CLANG_ATOMIC* macros, etc. match on the host and
2 // device sides of CUDA compilations. Note that we filter out long double and
3 // maxwidth of _BitInt(), as this is intentionally different on host and device.
5 // Also ignore __CLANG_ATOMIC_LLONG_LOCK_FREE on i386. The default host CPU for
6 // an i386 triple is typically at least an i586, which has cmpxchg8b (Clang
7 // feature, "cx8"). Therefore, __CLANG_ATOMIC_LLONG_LOCK_FREE is 2 on the host,
8 // but the value should be 1 for the device.
10 // FIXME: We really should make __GCC_HAVE_SYNC_COMPARE_AND_SWAP identical on
11 // host and device, but architecturally this is difficult at the moment.
