| 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. |

| 67 | MS VC++, especially for function pointers, so we won't use it for |
| 68 | now on that platform. It may be reconsidered for a future release |
| 69 | if it can be made more effective. |
| 70 | Likely reason: __fastcall on Windows is like stdcall, therefore |
| 71 | the compiler cannot perform stack optimizations for call clusters. |
