-<p>The following components of this LLVM release are either untested, known to
-   be broken or unreliable, or are in early development.  These components
-   should not be relied on, and bugs should not be filed against them, but they
-   may be useful to some people.  In particular, if you would like to work on
-   one of these components, please contact us on

+<p>LLVM is generally a production quality compiler, and is used by a broad range
+   of applications and shipping in many products.  That said, not every
+   subsystem is as mature as the aggregate, particularly the more obscure
+   targets.  If you run into a problem, please check the <a
+   href="http://llvm.org/bugs/">LLVM bug database</a> and submit a bug if
+   there isn't already one or ask on the <a
+    href="http://lists.cs.uiuc.edu/mailman/listinfo/llvmdev">LLVMdev
+    list</a>.</p>

-      XCore backends are experimental.</li>
+  <li>The Alpha, Blackfin, CellSPU, MSP430, PTX, SystemZ and

-      the <tt>va_arg</tt> LLVM IR instruction</a>. Currently, front-ends support

-  <li>Thumb mode works only on ARMv6 or higher processors. On sub-ARMv6

-<p>The C backend has numerous problems and is not being actively maintained.
-   Depending on it for anything serious is not advised.</p>
-
-<ul>
-  <li><a href="http://llvm.org/PR802">The C backend has only basic support for
-      inline assembly code</a>.</li>
-
-  <li><a href="http://llvm.org/PR1658">The C backend violates the ABI of common
-      C++ programs</a>, preventing intermixing between C++ compiled by the CBE
-      and C++ code compiled with <tt>llc</tt> or native compilers.</li>
-
-  <li>The C backend does not support all exception handling constructs.</li>
-
-  <li>The C backend does not support arbitrary precision integers.</li>
+  <li>The integrated assembler, disassembler, and JIT is not supported by
+      several targets.  If an integrated assembler is not supported, then a
+      system assembler is required.  For more details, see the <a
+      href="CodeGenerator.html#targetfeatures">Target Features Matrix</a>.
