Subject [jira] Updated: (HARMONY-4901) [drlvm][jit] escape analysis fails with logging
Date Sat, 02 Feb 2008 17:14:09 GMT

     [ https://issues.apache.org/jira/browse/HARMONY-4901?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Egor Pasko updated HARMONY-4901:
--------------------------------

    Attachment: escape-logging-more-enhancement.txt

my tiny enhancement over Pavel's:

escape-logging-more-enhancement.txt

1. got rid of evil getMD()
2. implemented more tricky cases in EscAnalyzer::printCallMethodName
3. Log::out() was replaced with locally written stream for abstract convenience
4. some trailing whitespace killed

now it does not crash for me with -Xem:opt

> There're couple of NULL pointer dereferences in escape analysis code while logging is
enabled.
> The main reason is unknown, I believe that my patch is just the workaround.
> I have added this line to server.emconf to enable logging:
> -XDjit.SD2_OPT.arg.log=ct,irdump,dbg,escape_verbose
