<p>Pro's of clang vs Elsa:</p>
<ul>
<li>Clang's C and C++ support is far more mature and practically useful than
Elsa's, and includes many C++'0x features.</li>
<li>The Elsa community is extremely small and major development work seems
to have ceased in 2005. Work continued to be used by other small
projects (e.g. Oink), but Oink is apparently dead now too. Clang has a

<li>Elsa does not support native code generation.</li>
</ul>
<p>Note that there is a fork of Elsa known as "Pork". It addresses some of
these shortcomings by loosely integrating a preprocessor. This allows it
to map from a source location in the AST to the original position before
preprocessing, providing it better support for static analysis and
refactoring. Note that Pork is in stasis now too.</p>
