+%% @doc This is the direct interface to the HiPE compiler.
+%%
+%% <h3>Normal use</h3>
+%%
+%% <p>The normal way to native-compile an Erlang module using HiPE is to
+%% include the atom <code>native</code> in the Erlang compiler options,
+%% as in:
+%%
+%% <pre> 1> c(my_module, [native]).</pre></p>
+%%
+%% <p>Options to the HiPE compiler are then passed as follows:
+%%
+%% <pre> 1> c(my_module, [native,{hipe,Options}]).</pre></p>
+%%
+%% <p>For on-line help in the Erlang shell, call <a
+%% href="#help-0"><code>hipe:help()</code></a>. Details on HiPE compiler
+%% options are given by <a
+%% href="#help_options-0"><code>hipe:help_options()</code></a>.</p>
+%%
+%% <h3>Using the direct interface - for advanced users only</h3>
+%%
+%% To compile a module or a specific function to native code and
+%% automatically load the code into memory, call <a
+%% href="#c-1"><code>hipe:c(Module)</code></a> or <a
+%% href="#c-2"><code>hipe:c(Module, Options)</code></a>. Note that all
+%% options are specific to the HiPE compiler. See the <a
+%% href="#index">function index</a> for other compiler functions.
+%%
+%% <h3>Main Options</h3>
+%%
+%% Options are processed in the order they appear in the list; an
+%% early option will shadow a later one.
+%% <dl>
+%% <dt><code>o0, 'O0', o1, 'O1', o2, 'O2', o3, 'O3'</code></dt>

+%% <dd>Sets the time the compiler is allowed to use for the
+%% compilation. <code>Time</code> is time in ms or the atom
+%% <code>infinity</code> (the default).</dd>
+%%
+%% <dt><code>verbose</code></dt>
+%% <dd>Make the HiPE compiler output information about what it is
+%% being done.</dd>
+%% </dl>
+%%
+%% <h3>Advanced Options</h3>
+%%
+%% Note: You can also specify <code>{Option, false}</code> to turn a
+%% particular option off, or <code>{Option, true}</code> to force it on.
+%% Boolean-valued (<code>true</code>/<code>false</code>) options also
+%% have negative-form aliases, e.g. <code>no_load</code> = <code>{load,

+%% Filename : hipe.hrl (automatically generated by hipe.hrl.src)
+%% Purpose : Defines some useful macros for debugging and error
+%% reporting.
+%%
+%% History : * 2000-11-03 Erik Johansson (happi@it.uu.se): Created.
+%% ====================================================================
+%%
+%% Defines:
+%% msg/2 - Works like io:format but prepends
+%% ?MSGTAG to the message.
+%% If LOGGING is defined then error_logger is used,
+%% or rather its substitute in code_server.
+%% untagged_msg/2 - Like msg/2 but without the tag.
+%% WARNING_MSG/2 - Prints a tagged warning.
+%% error_msg/2 - Logs a tagged error.
+%% debug_msg/2 - Prints a tagged msg if DEBUG is defined.
+%% IF_DEBUG(A,B) - Executes A if DEBUG is defined B otherwise.
+%% IF_DEBUG(Lvl,A,B) - Executes A if DEBUG is defined to a value >= Lvl
+%% otherwise B is executed.
+%% EXIT - Exits with added module and line info.
+%% ASSERT - Exits if the expresion does not evaluate to true.
+%% VERBOSE_ASSSERT - A message is printed even when an asertion is true.
+%% TIME_STMNT(Stmnt, String, FreeVar)
+%% - Times the statemnet Stmnt if TIMING is on.
+%% The execution time is bound to FreeVar.
+%% String is printed after the execution
+%% followed by the execution time in seconds and
+%% a newline.
+%%
+%% Flags:
+%% DEBUG - Turns on debugging. (Can be defined to a integer
+%% value to determine the level of debugging)
+%% VERBOSE - More info is printed...
+%% HIPE_LOGGING - Turn on logging of messages with erl_logger.
+%% DO_ASSERT - Turn on Assertions.
+%% TIMING - Turn on timing.
+%% HIPE_INSTRUMENT_COMPILER - Turn on instrumentation of the compiler.
