Douglas Gregor8c327082011-07-21 17:46:15 +0000[diff] [blame]30<p>Clang currently implements all of the ISO C++ 1998 standard
31 (including the defects addressed in the ISO C++ 2003 standard)
David Blaikie1e2b3d72011-10-14 07:58:10 +0000[diff] [blame]32 except for 'export' (which has been removed in C++'11)
Douglas Gregor8c327082011-07-21 17:46:15 +0000[diff] [blame]33 and is considered a production-quality C++ compiler. The <a
34 href="http://llvm.org/bugs/">LLVM bug tracker</a> contains a Clang
35 C++ component that tracks known Clang C++ bugs.</p>

Douglas Gregor43ac6d02011-10-14 23:21:49 +0000[diff] [blame]39 <p>Clang provides support for a number of features included in the new <a href="http://www.iso.org/iso/iso_catalogue/catalogue_tc/catalogue_detail.htm?csnumber=50372">ISO C++ Standard, ISO/IEC 14882:2011</a>.

David Blaikie1e2b3d72011-10-14 07:58:10 +0000[diff] [blame]42<p>You can use Clang in C++11 mode either
Jeffrey Yasskin46ba01a2011-03-29 22:27:50 +0000[diff] [blame]43with <a href="http://libcxx.llvm.org/">libc++</a> or with gcc's libstdc++.
