[PATCH] D36810: Minimal runtime for UBSan.

[Evgenii Stepanov via Phabricator via llvm-commits]

eugenis updated this revision to Diff 112625.
eugenis added a comment.

Now with tests and better diagnostics in the driver.

Disabled minimal runtime with CFI because cross-dso cfi does not know how to handle an error without diagnostic data.
Minimal runtime is not realy necessary with cross-dso cfi, because the stack trace very clearly points to the problem.
