| * Rudimentary startup function. Only called in the "application" half of a |
| * split image. |
| * |
| * If the loader and app both used the same start symbol (_start), the |
| * loader's main() gets used by the app, rather than the app's main. This |
| * causes the linker to strip pretty much all functionality from the app. |
| * |
| * The solution is to use a different start symbol for the "application" |
| * half of a split image. Rather than _start, the app uses _start_split. |
| * |
| * In addition, due to the way newt builds split images, _start_split has |
| * to reside in a package that the loader doesn't use. If it is in a |
| * shared package, the entire package gets put in the loader, and |
| * _start_split would erroneously reference the loader's main(). |
