In this release, the following missing features were implemented:<p>
<ol>
<li><a href="http://llvm.cs.uiuc.edu/PR88">The interpreter does not support
invoke or unwind</a></li>

</ul><b>Bugs:</b><ul><p>
-<li><a href="http://llvm.cs.uiuc.edu/PR6">Oversized integer bitfields cause crash</a>.<p>
-
<li>C99 Variable sized arrays do not release stack memory when they go out of
scope. Thus, the following program may run out of stack space:
<pre>
supported</a>. This should not affect LLVM produced by the C or C++
frontends.<p>
-<li><a href="http://llvm.cs.uiuc.edu/PR77">Variables in scope of output setjmp
-calls should be volatile</a>. Note that this does not effect correctness on
-many platforms.<p>
-
<li>The code produces by the C back-end has only been tested with the Sun CC,
GCC, and Intel compilers. It is possible that it will have to be adjusted to
support other C compilers.<p>
