77At this time, LLVM is known to correctly compile and run all C &amp; C++ SPEC
78CPU2000 benchmarks, the Olden benchmarks, and the Ptrdist benchmarks. It has
79also been used to compile <b>many</b> other programs. LLVM now also works with
80a broad variety of C++ programs, though it has still received less testing than
81the C front-end.

Chris Lattner62495762003-10-02 16:38:05 +0000[diff] [blame]195The core LLVM infrastructure uses "autoconf" for portability, so hopefully we

Chris Lattner62495762003-10-02 16:38:05 +0000[diff] [blame]491<li>The LLVM C++ front-end follows the <a
492 href="http://www.codesourcery.com/cxx-abi">Itanium C++ ABI</a>.
493 This document, which is not Itanium specific, specifies a standard for name
494 mangling, class layout, v-table layout, RTTI formats, and other C++
495 representation issues. Because we use this API, code generated by the LLVM
496 compilers should be binary compatible with machine code generated by other
497 Itanium ABI C++ compilers (such as G++, the Intel and HP compilers, etc).
498 <i>However</i>, the exception handling mechanism used by LLVM is very
499 different from the model used in the Itanium ABI, so <b>exceptions will not
