| andrewbonney | 0:07919e3d6c56 | 3 | Internal definitions used by Expat. This is not needed to compile |

| andrewbonney | 0:07919e3d6c56 | 6 | The following calling convention macros are defined for frequently |
| andrewbonney | 0:07919e3d6c56 | 7 | called functions: |
| andrewbonney | 0:07919e3d6c56 | 8 | |
| andrewbonney | 0:07919e3d6c56 | 9 | FASTCALL - Used for those internal functions that have a simple |
| andrewbonney | 0:07919e3d6c56 | 10 | body and a low number of arguments and local variables. |
| andrewbonney | 0:07919e3d6c56 | 11 | |
| andrewbonney | 0:07919e3d6c56 | 12 | PTRCALL - Used for functions called though function pointers. |
| andrewbonney | 0:07919e3d6c56 | 13 | |
| andrewbonney | 0:07919e3d6c56 | 14 | PTRFASTCALL - Like PTRCALL, but for low number of arguments. |
| andrewbonney | 0:07919e3d6c56 | 15 | |
| andrewbonney | 0:07919e3d6c56 | 16 | inline - Used for selected internal functions for which inlining |
| andrewbonney | 0:07919e3d6c56 | 17 | may improve performance on some platforms. |
| andrewbonney | 0:07919e3d6c56 | 18 | |
| andrewbonney | 0:07919e3d6c56 | 19 | Note: Use of these macros is based on judgement, not hard rules, |
| andrewbonney | 0:07919e3d6c56 | 20 | and therefore subject to change. |

| andrewbonney | 0:07919e3d6c56 | 38 | MS VC++, especially for function pointers, so we won't use it for |

| andrewbonney | 0:07919e3d6c56 | 40 | if it can be made more effective. |
| andrewbonney | 0:07919e3d6c56 | 41 | Likely reason: __fastcall on Windows is like stdcall, therefore |
