| 25 // The following alternative implementations are needed because | |
| 26 // Windows 95 doesn't support (some of) the corresponding Windows NT | |
| 27 // calls. Furthermore, these versions allow inlining in the caller. | |
| 28 // (More precisely: The documentation for InterlockedExchange says | |
| 29 // it is supported for Windows 95. However, when single-stepping | |
| 30 // through the assembly code we cannot step into the routine and | |
| 31 // when looking at the routine address we see only garbage code. | |
| 32 // Better safe then sorry!). Was bug 7/31/98 (gri). | |
| 33 // | |
| 34 // Performance note: On uniprocessors, the 'lock' prefixes are not | |
| 35 // necessary (and expensive). We should generate separate cases if | |
| 36 // this becomes a performance problem. | |
