| 21 | // the following help macro is to guarentee that certain coded |
| 22 | // is not removed by over-eager linker optimiser. In certain cases |
| 23 | // we create static objects must be created but are actually never |
| 24 | // referenced - creation has a side-effect such as global registration |
| 25 | // which is important to us. We make an effort to refer these objects |
| 26 | // so that a smart linker won't remove them as being unreferenced. |
| 27 | // In microsoft compilers, inlining the code that does the referring |
| 28 | // means the code gets lost and the static object is not included |
| 29 | // in the library and hence never registered. This manifests itself |
| 30 | // in an ungraceful crash at runtime when (and only when) built in |
| 31 | // release mode. |
