Subject [jira] Commented: (HARMONY-2804) [drlvm][jit] StackTest and gc.Mark fail if Jitrino built in debug mode
Date Wed, 17 Jan 2007 10:15:27 GMT

    [ https://issues.apache.org/jira/browse/HARMONY-2804?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12465407
] 

Mikhail Fursov commented on HARMONY-2804:
-----------------------------------------

Naveen, 
I've commited a fix for StackTest, please check.

Problem description:
The old GCMap code knows nothing about SOE and contains info only for NPE and calls. When
SOE is thrown (arbitrary push op) and GC starts enumeration and GCMap can't find an image
for the given IP -> assertion happens -> that was OK before we had SOE handling and
this is not correct today.

The patch must fix the problem, however we need to reconsider if we still need to save NPE
images in GCMap in debug mode. One of the most important usage scenario of them (the assertion)
has gone.

> I am a JIT developer and as a result I generally run DRLVM with jitrino build in debug
mode.  However, the drlvm tests do not pass in this mode.
