Chris Lattner62495762003-10-02 16:38:05 +0000[diff] [blame]464<li>The LLVM C++ front-end follows the <a
465 href="http://www.codesourcery.com/cxx-abi">Itanium C++ ABI</a>.
466 This document, which is not Itanium specific, specifies a standard for name
467 mangling, class layout, v-table layout, RTTI formats, and other C++
468 representation issues. Because we use this API, code generated by the LLVM
469 compilers should be binary compatible with machine code generated by other
470 Itanium ABI C++ compilers (such as G++, the Intel and HP compilers, etc).
471 <i>However</i>, the exception handling mechanism used by LLVM is very
472 different from the model used in the Itanium ABI, so <b>exceptions will not
