/* internal.h

   Internal definitions used by Expat.  This is not needed to compile

   client code.

   The following calling convention macros are defined for frequently

   called functions:

   FASTCALL    - Used for those internal functions that have a simple

                 body and a low number of arguments and local variables.

   PTRCALL     - Used for functions called though function pointers.

   PTRFASTCALL - Like PTRCALL, but for low number of arguments.

   inline      - Used for selected internal functions for which inlining

                 may improve performance on some platforms.

   Note: Use of these macros is based on judgement, not hard rules,

         and therefore subject to change.

   regparm() generates warnings on Solaris boxes.   See SF bug #692878.

   Instability reported with egcs on a RedHat Linux 7.3.

   Let's comment out:

   #define FASTCALL __attribute__((stdcall, regparm(3)))

   and let's try this:

*/

#define FASTCALL __attribute__((regparm(3)))

#define PTRFASTCALL __attribute__((regparm(3)))

/* Using __fastcall seems to have an unexpected negative effect under

   MS VC++, especially for function pointers, so we won't use it for

   now on that platform. It may be reconsidered for a future release

   if it can be made more effective.

   Likely reason: __fastcall on Windows is like stdcall, therefore

   the compiler cannot perform stack optimizations for call clusters.
