+ <list>
+ <item>
+ <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>
