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 Lattner19092612003-10-02 16:38:05 +0000[diff] [blame]167The core LLVM infrastructure uses "autoconf" for portability, so hopefully we
Chris Lattner3e2959e2003-11-08 05:22:09 +0000[diff] [blame]168work on more platforms than that. However, it is likely that we
John Criswelld000e1d2003-12-18 16:43:17 +0000[diff] [blame]169missed something and that minor porting is required to get LLVM to work on
Misha Brukman500bc302003-11-22 00:38:41 +0000[diff] [blame]170new platforms. We welcome portability patches and error messages.</p>

Chris Lattner79c3fe12003-10-02 04:57:28 +0000[diff] [blame]455<li>The C++ front-end is based on a pre-release of the GCC 3.4 C++ parser. This
456parser is significantly more standards compliant (and picky) than prior GCC
457versions. For more information, see the C++ section of the <a

Chris Lattner19092612003-10-02 16:38:05 +0000[diff] [blame]466<li>The LLVM C++ front-end follows the <a
467 href="http://www.codesourcery.com/cxx-abi">Itanium C++ ABI</a>.
468 This document, which is not Itanium specific, specifies a standard for name
469 mangling, class layout, v-table layout, RTTI formats, and other C++
470 representation issues. Because we use this API, code generated by the LLVM
471 compilers should be binary compatible with machine code generated by other
472 Itanium ABI C++ compilers (such as G++, the Intel and HP compilers, etc).
473 <i>However</i>, the exception handling mechanism used by LLVM is very
474 different from the model used in the Itanium ABI, so <b>exceptions will not

516<li>The C back-end produces code that violates the ANSI C Type-Based Alias
517Analysis rules. As such, special options may be necessary to compile the code
518(for example, GCC requires the <tt>-fno-strict-aliasing</tt> option). This
