<ul>
<li>Support for <code>__builtin_shufflevector</code> compatible with
the clang language extension was added.
</li>
- <li>The <code>-Wattributes</code> option has been extended so that it's
- possible to use <code>-Wno-attributes=ns::attr</code> or
- <code>-Wno-attributes=ns::</code> to suppress warnings about unknown scoped
- attributes (in C++11 and C2X). Similarly,
- <code>#pragma GCC diagnostic ignored_attributes "vendor::attr"</code> can
- be used to achieve the same effect.</li>
+ <li>New warnings:
+ <ul>
+ <li><code>-Wbidi-chars</code> warns about potentially misleading UTF-8
+ bidirectional control characters. The default is <code>-Wbidi-chars=unpaired</code>.
+ </li>
