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)
32 except for 'export' (which has been removed from the C++'0x draft)
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>
