[PATCH] D70172: [CUDA][HIP][OpenMP] Emit deferred diagnostics by a post-parsing AST travese

[Yaxun Liu via Phabricator via cfe-commits]

yaxunl updated this revision to Diff 247275.
yaxunl added a comment.

Do not traverse the whole CU. Record potentially emitted functions and variables in the normal parsing and traverse them instead.

Also fixed bug 44948 and regression in check-mlir.
