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

26 regparm() generates warnings on Solaris boxes. See SF bug #692878.
28 Instability reported with egcs on a RedHat Linux 7.3.
29 Let's comment out:
30 #define FASTCALL __attribute__((stdcall, regparm(3)))
31 and let's try this:

37 /* Using __fastcall seems to have an unexpected negative effect under
38 MS VC++, especially for function pointers, so we won't use it for
39 now on that platform. It may be reconsidered for a future release
40 if it can be made more effective.
41 Likely reason: __fastcall on Windows is like stdcall, therefore
42 the compiler cannot perform stack optimizations for call clusters.
