[PATCH] D153001: [clang][ThreadSafety] Add __builtin_instance_member (WIP)

[Timm Bäder via Phabricator via cfe-commits]

tbaeder added a comment.

Didn't remember and re-checked, using it that way makes the implementation harder I think:

  tsa2.c:7:54: error: incomplete definition of type 'struct Mutex'
      7 |   int counter GUARDED_BY(__builtin_instance_member(M)->M);
        |                                                      ^
  tsa2.c:6:10: note: forward declaration of 'struct Mutex'
      6 |   struct Mutex *M;
        |          ^
  1 error generated.

and I didn't immediately know how to fix that.
