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. |

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. |
