    • Verified

        --------------------------------------
        Test : jit/common/FPCompare/TestFPBinop
        TestBase : testbase_vm
        VM : Server
        Mode : -Xcomp
        Platform : RedHat Linux 7.2, Windows XP ( ia64)
        JDK : 1.4.2 beta (b16)
        ----------------------------------------
        This test passed with -Xmixed mode on lin64/win64 and other
        platforms with -Xcomp and -Xmixed.

        Test of Floating Point Binary Ops.
        This is intended to be run on a known-correct system and the
        answer compared with the golden answer with diff or equivalent.

        Step to reproduce
        1. cd /net/sqesvr.eng/export/vsn/GammaBase/Bugs/{BugID}
        2. sh rerun.sh
