Subject [jira] Resolved: (HARMONY-1578) [drlvm][jit][opt] Several bugs in Jitrino.OPT fixed
Date Thu, 18 Jan 2007 06:26:30 GMT

     [ https://issues.apache.org/jira/browse/HARMONY-1578?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Alexey Varlamov resolved HARMONY-1578.
--------------------------------------

    Resolution: Fixed

Tests behave a bit differently to me: fcmp/dcmp fail on both ia32 and x64 but NaN comparison
works on both.
Still the patches look correct, applied both at r497005.

This required some manual merging, please verify it is done correctly.
