[jira] Updated: (HARMONY-2115) [drlvm][jit][opt] "syncopt"
optimization pass crashes (on HelloWorld) because expects old CFG structure
[ http://issues.apache.org/jira/browse/HARMONY-2115?page=all ]
Egor Pasko updated HARMONY-2115:
--------------------------------
Attachment: 0001-syncopt-fixed.txt
the fix attached (absolutely safe to commit, syncopt is unused now)
with fix applied you will get a crash in DominatorTree which is another issue:
SIGSEGV in VM code.
Stack trace:

2: Jitrino::LoopTree::findLoopHeaders(Jitrino::StlVector<Jitrino::Node*, Jitrino::StlMMAllocator<Jitrino::Node*> >&) (??:-1)
