`-fcatch-undefined-behavior` and `-fbounds-checking` were removed in favor of
`-fsanitize=` family of flags.
+It is now possible to get optimization reports from the major transformation
+passes via three new flags: `-Rpass`, `-Rpass-missed` and `-Rpass-analysis`.
+These flags take a POSIX regular expression which indicates the name
+of the pass (or passes) that should emit optimization remarks.
+
+New Pragmas in Clang
+-----------------------
+
+Loop optimization hints can be specified using the new `#pragma clang loop`
+directive just prior to the desired loop. The directive allows vectorization,
+interleaving, and unrolling to be enabled or disabled. Vector width as well
+as interleave and unrolling count can be manually specified. See language
+extensions for details.
