> unreachable nodes must be swept out after inliner
> -------------------------------------------------
>
> Key: HARMONY-2210
> URL: http://issues.apache.org/jira/browse/HARMONY-2210
> Project: Harmony
> Issue Type: Bug
> Components: DRLVM
> Reporter: George Timoshenko
> Attachments: test.java
>
>
> inline pass of Jitrino.OPT::optimizer can produce unreachable nodes. (the testcase is attached)
> some other passes can not work with such nodes in the CFG.
> Attached testcase breaks on DCE pass after inliner. (run with -Xem:opt ):
> java: /export/users2/gatimosh/HARMONY_SVN/trunk/working_vm/vm/jitrino/src/optimizer/deadcodeeliminator.cpp:554: void Jitrino::markLiveInst(Jitrino::Inst*, Jitrino::InstDeque&, Jitrino::BitSet&, Jitrino::BitSet&, uint8*, unsigned int, unsigned int): Assertion `def->getNode()' failed.
> It is not so easy to teach inliner not to create unreachables.
