%% 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 ([email protected]): 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)
%% 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.
