* Fix hang in do-while loops with continue statement in the bodySimon Hausmann2013-01-041-1/+7
| | | | | | | | | | | | | | | | | | | | The construct do { ... continue; } while (condition) Would result in the body basic block ending with a jump to the loop body, causing an infinite loop. Instead we have to place the condition into an extra block and set that one as the target for continue. This is also covered by ch12/12.14/S12.14_A9_T2, which uses such a loop.

* Fix native stack traversalSimon Hausmann2012-12-172-8/+34
| | | | | | | | | | | | | | | | | | | | | | * For the traversal range, don't take the top of the stack but one value pointer below, as the top is actually the end of the stack and we can't read beyond it. For the bottom go one pointer beyond a locally declared (and thus aligned) value. This ensure sane and aligned boundaries for the traversal. * For quick elimination of pointer values on the stack that do not actually point into one of our managed objects, implement Lars' idea: Take the heap chunk beginning and end pointers and do a lower bound search. An even index indicates that the pointer is before the start of a chunk, thus out of range. An odd index indicates that it is before a chunk end and therefore in range. * For obscure reasons we also seem to sometimes hit "dangling" pointers into otherwise already dealloc'ed objects (as debug output in dealloc() indicates), so protect ourselves against that.
