| | | | | Define new functions that use the kernel support to do a backtrace of other tasks than current.

* Use 'static' as much as possibleJosh Stone2009-01-2837-198/+197
| | | | | | | | | | This change just inserts 'static' on runtime, tapset, and generated C functions and globals, so the compiler can do a better job of optimizing. My tests with small scripts show ~10% reduction in compile time and ~20% reduction in module size. Larger scripts may show less benefit, but I expect purely positive results.
