[PATCH] D69759: [BPF] Add preserve_access_index attribute for record definition

[Yonghong Song via Phabricator via cfe-commits]

yonghong-song updated this revision to Diff 228583.
yonghong-song added a comment.

The Decl "D" could be a nullptr in ProcessDeclAttributeDelayed, which will cause segfault. Handle this properly.
Also addressed most of Aaron's comments.
