+	    Add function <c>hipe:erllvm_is_supported</c> to check for
+	    the presences of a suitable version of the LLVM tool
+	    chain as well as supported hardware architecture. The old
+	    <c>hipe:llvm_support_available</c> has been removed.</p>

+	    <p>In OTP 22, HiPE (the native code compiler) is not
+	    fully functional. The reasons for this are:</p>
+	    <p>There are new BEAM instructions for binary matching
+	    that the HiPE native code compiler does not support.</p>
+	    <p>The new optimizations in the Erlang compiler create
+	    new combination of instructions that HiPE currently does
+	    not handle correctly.</p>
+	    <p>If erlc is invoked with the <c>+native</c> option, and
+	    if any of the new binary matching instructions are used,
+	    the compiler will issue a warning and produce a BEAM file
+	    without native code.</p>
