* Fixed PR 11220 by setting MAP_STRING_LENGTH to MAXSTRINGLEN.David Smith2010-01-251-3/+5
| | | | | | * runtime/map.h: Set MAP_STRING_LENGTH to MAXSTRINGLEN so that large strings can be stored in arrays. * testsuite/systemtap.base/array_string.exp: New testcase.
* Use 'static' as much as possibleJosh Stone2009-01-281-15/+15
| | | | | | | | | | 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.
