[Dan Liew via Phabricator via cfe-commits]

delcypher added inline comments.


================
Comment at: clang/lib/Basic/IdentifierTable.cpp:111
     KEYSYCL       = 0x1000000,
+    KEYCUDA       = 0x2000000,
     KEYALLCXX = KEYCXX | KEYCXX11 | KEYCXX20,
----------------
@yaxunl Is it intentional that you didn't update `KEYALL` here? That means `KEYALL` doesn't include the bit for `KEYCUDA`.

If that was your intention then this will break if someone adds a new key. E.g.

```
KEYCUDA = 0x2000000,
KEYSOMENEWTHING = 0x4000000,
// ...
// KEYALL now includes `KEYCUDA`, whereas it didn't before.
// KEYALL includes KEYSOMENEWTHING 
KEYALL = (0x7ffffff & ~KEYNOMS18 &
              ~KEYNOOPENCL) // KEYNOMS18 and KEYNOOPENCL are used to exclude.
...
```


1. Updating the `0x1ffffff` constant to `0x3ffffff` so that `KEYALL` includes `KEYCUDA`
2. If your intention **is** to not have `KEYCUDA`  set in `KEYALL` then amend `KEYALL` to be.

```
KEYALL = (0x7ffffff & ~KEYNOMS18 &
              ~KEYNOOPENCL & ~KEYCUDA ) // KEYNOMS18 and KEYNOOPENCL are used to exclude.
// KEYCUDA is not included in KEYALL
```
