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.

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