/* 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)))
|
||
|
|
#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.
