241be broken or unreliable, or are in early development. These components should
242not be relied on, and bugs should not be filed against them, but they may be
243useful to some people. In particular, if you would like to work on one of these

Chris Lattner79c3fe12003-10-02 04:57:28 +0000489<li>The C++ front-end is based on a pre-release of the GCC 3.4 C++ parser. This
490parser is significantly more standards compliant (and picky) than prior GCC
491versions. For more information, see the C++ section of the <a

Chris Lattner19092612003-10-02 16:38:05 +0000495 performed. In particular, destructors for objects in the <tt>longjmp</tt>ing

John Criswelld000e1d2003-12-18 16:43:17 +0000497 Objects in intervening stack frames will be destroyed, however (which is
Misha Brukman500bc302003-11-22 00:38:41 +0000498 better than most compilers).</li>

Chris Lattner19092612003-10-02 16:38:05 +0000500<li>The LLVM C++ front-end follows the <a
501 href="http://www.codesourcery.com/cxx-abi">Itanium C++ ABI</a>.
502 This document, which is not Itanium specific, specifies a standard for name
503 mangling, class layout, v-table layout, RTTI formats, and other C++
504 representation issues. Because we use this API, code generated by the LLVM
505 compilers should be binary compatible with machine code generated by other
506 Itanium ABI C++ compilers (such as G++, the Intel and HP compilers, etc).
507 <i>However</i>, the exception handling mechanism used by LLVM is very
508 different from the model used in the Itanium ABI, so <b>exceptions will not
Misha Brukman500bc302003-11-22 00:38:41 +0000509 interact correctly</b>. </li>
