<p>
The normal way to native-compile an Erlang module using HiPE is to include the atom native
- in the Erlang compiler options, as in:
- <code>
- 1> <input>c(my_module, [native]).</input></code>
- Options to the HiPE compiler are then passed as follows:
- <code>
- 1> <input>c(my_module, [native,{hipe,Options}]).</input></code>
- For on-line help in the Erlang shell, call <c>hipe:help()</c>.
- Details on HiPE compiler options are given by <c>hipe:help_options()</c>.
