/* INLINE CODE SELECTION:

   GCC -O3 attempts to inline any function or procedure in scope.  The
   options below facilitate finer grained control over what is and
   what is not inlined.  In particular, it allows the selection of
   modules for inlining.  Doing this allows the compiler to both
   eliminate the overhead of function calls and (as a consequence)
   also eliminate further dead code.

   On a CISC (x86) I've found that I can achieve an order of magnitude
   speed improvement (x3-x5).  In the case of RISC (sparc) while the
   performance gain isn't as great it is still significant.

   Each module is controled by the macro <module>_INLINE which can
   have the values described below

       0 (ZERO)

         Do not inline any thing for the given module

   The following bit fields values can be combined:

      H_REVEALS_MODULE:
      C_REVEALS_MODULE:

         Include the C file for the module into the file being
         compiled.  The actual inlining is controlled separatly.

	 While of no apparent benefit, this makes it possible for the
	 included module, when compiled, to inline its calls to what
	 would otherwize be external functions.

	 {C_,H_} Determines where the module is inlined.  A
	 H_REVEALS_MODULE will be included everywhere.

      INLINE_GLOBALS:

         Make external functions within the module `inline'.  Thus if
         the module is included into a file being compiled, calls to
	 the included modules funtions can be eliminated.  INLINE_MODULE
	 implies REVEAL_MODULE.

      INLINE_LOCALS:

         Make internal (static) functions within the module `inline'.


   CODING STYLE:

   The inline ability is enabled by specifying every data and function
   declaration and definition using one of the following methods:


       GLOBAL INLINE FUNCTIONS:

          Such functions are small and used heavily.  Inlining them
          will eliminate an unnecessary function call overhead.

	  .h: INLINE_OURPKG (void) ourpkg_func
	      (int x,
	       int y);

	  .c: INLINE_OURPKG (void)
	      ourpkg_func (int x,
	                   int y)
	      {
	        ...
	      }


       GLOBAL INLINE VARIABLES:

          This doesn't make much sense.


       GLOBAL NON-INLINE (EXTERN) FUNCTIONS AND VARIABLES:

          These include functions with varargs parameters.  It can
          also include large rarely used functions that contribute
          little when inlined.

	  .h: extern int ourpkg_print
	      (char *fmt, ...);
	      extern int a_global_variable;

	  .c: #if EXTERN_OURPKG_P
	      int
	      ourpkg_print (char *fmt,
	                    ...)
              {
	         ...
	      }
	      #endif
	      #if EXTERN_OURPKG_P
	      int a_global_variable = 1;
	      #endif


       LOCAL (STATIC) FUNCTIONS:

          These can either be marked inline or just static static vis:

	  .h: STATIC_INLINE_OURPKG (int) ourpkg_staticf (void);
	  .c: STATIC_INLINE_OURPKG (int)
	      ourpkg_staticf (void)
	      {
	        ..
	      }

	  .h: STATIC_OURPKG (int) ourpkg_staticf (void);
	  .c: STATIC_OURPKG (int)
	      ourpkg_staticf (void)
	      {
	        ..
	      }


       All .h files:


          All modules must wrap their .h code in the following:

	  #ifndef OURPKG_H
	  #define OURPKG_H
	  ... code proper ...
	  #endif

          In addition, modules that want to allow global inlining must
          include the lines (below) at the end of the .h file. (FIXME:
          Shouldn't be needed).

          #if H_REVEALS_MODULE_P (OURPKG_INLINE)
          #include "ourpkg.c"
          #endif


       All .c files:

          All modules must wrap their .c code in the following

	  #ifndef OURPKG_C
	  #define OURPKG_C
	  ... code proper ...
	  #endif


   NOW IT WORKS:

      0:

      Since no inlining is defined. All macro's get standard defaults
      (extern, static, ...).
      


      H_REVEALS_MODULE (alt includes our):


      altprog.c defines ALTPROG_C and then includes sim-inline.h.

      In sim-inline.h the expression `` H_REVEALS_MODULE_P
      (OURPROG_INLINE) && !  defined (OURPROG_C) && REVEAL_MODULE_P
      (OURPROG_INLINE) '' is TRUE so it defines *_OURPROG as static
      and EXTERN_OURPROG_P as FALSE.

      altprog.c includes ourprog.h.

      In ourprog.h the expression ``H_REVEALS_MODULE_P
      (OURPROG_INLINE)'' is TRUE so it includes ourprog.c.

      Consequently, all the code in ourprog.c is visible and static in
      the file altprog.c



      H_REVEALS_MODULE (our includes our):


      ourprog.c defines OURPROG_C and then includes sim-inline.h.

      In sim-inline.h the term `` ! defined (OURPROG_C) '' is FALSE so
      it defines *_OURPROG as non-static and EXTERN_OURPROG_P as TRUE.

      ourprog.c includes ourprog.h.

      In ourprog.h the expression ``H_REVEALS_MODULE_P
      (OURPROG_INLINE)'' is true so it includes ourprog.c.

      In ourprog.c (second include) the expression defined (OURPROG_C)
      and so the body is not re-included.

      Consequently, ourprog.o will contain a non-static copy of all
      the exported symbols.



      C_REVEALS_MODULE (alt includes our):


      altprog.c defines ALTPROG_C and then includes sim-inline.c

      sim-inline.c defines C_INLINE_C and then includes sim-inline.h
      
      In sim-inline.h the expression `` defined (SIM_INLINE) && !
      defined (OURPROG_C) && REVEAL_MODULE_P (OURPROG_INLINE) '' is
      true so it defines *_OURPROG as static and EXTERN_OURPROG_P as
      FALSE.

      In sim-inline.c the expression ``C_REVEALS_MODULE_P
      (OURPROG_INLINE)'' is true so it includes ourprog.c.

      Consequently, all the code in ourprog.c is visible and static in
      the file altprog.c.



      C_REVEALS_MODULE (our includes our):


      ourprog.c defines OURPROG_C and then includes sim-inline.c

      sim-inline.c defines C_INLINE_C and then includes sim-inline.h
      
      In sim-inline.h the term `` !  defined (OURPROG_C) '' is FALSE
      so it defines *_OURPROG as non-static and EXTERN_OURPROG_P as
      TRUE.

      Consequently, ourprog.o will contain a non-static copy of all
      the exported symbols.



   REALITY CHECK:

   This is not for the faint hearted.  I've seen GCC get up to 500mb
   trying to compile what this can create. */
