1/* internal.h
2
3   Internal definitions used by Expat.  This is not needed to compile
4   client code.
5
6   The following calling convention macros are defined for frequently
7   called functions:
8
9   FASTCALL    - Used for those internal functions that have a simple
10                 body and a low number of arguments and local variables.
11
12   PTRCALL     - Used for functions called though function pointers.
13
14   PTRFASTCALL - Like PTRCALL, but for low number of arguments.
15
16   inline      - Used for selected internal functions for which inlining
17                 may improve performance on some platforms.
18
19   Note: Use of these macros is based on judgement, not hard rules,
20         and therefore subject to change.

55   regparm() generates warnings on Solaris boxes.   See SF bug #692878.
56
57   Instability reported with egcs on a RedHat Linux 7.3.
58   Let's comment out:
59   #define FASTCALL __attribute__((stdcall, regparm(3)))
60   and let's try this:
61*/
62#  define FASTCALL __attribute__((regparm(3)))
63#  define PTRFASTCALL __attribute__((regparm(3)))
64#endif
65
66/* Using __fastcall seems to have an unexpected negative effect under
67   MS VC++, especially for function pointers, so we won't use it for
68   now on that platform. It may be reconsidered for a future release
69   if it can be made more effective.
70   Likely reason: __fastcall on Windows is like stdcall, therefore
71   the compiler cannot perform stack optimizations for call clusters.
