/* 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.

/* We'll use this version by default only where we know it helps.
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)))
#endif
/* 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.
