Subject [jira] Commented: (HARMONY-5262) [drlvm][gc_cc] GC_CC does not work in debug mode since r583223
Date Thu, 06 Dec 2007 21:55:43 GMT

    [ https://issues.apache.org/jira/browse/HARMONY-5262?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12549204
] 

Ilya Berezhniuk commented on HARMONY-5262:
------------------------------------------

I've detected additional problems with GC_CC:

- Looks like there is a mess in using static libraries; I had errors for not resolved symbols
from port, log4cxx, APR.
  After adding all these libraries to the libraries list gc_cc build file, I've got warning
from log4cxx that there is no appender...

- Some time ago the policy for exporting symbols was changed. Now only symbols listed in EXP
file are exported on Linux.
  But several required GC_CC functions was not there, so it did not work on Linux/x86_64.

> I've tried to pass 'build test' with GC_CC and got a lot of failures, and also several
random hangs.
> When investigating these problems, I've detected that hang occurs in shutdown (HARMONY-5247).
> But tests hanged with GC_CC on M3 snapshot (I've checked this).
> I've found that failures are caused by lots of assertions introduced by threading changes
from HARMONY-4830.
> The attached patch fixes GC_CC to reflect threading changes.
> It also corrects GC_CC according to r599482 which included changes in object layout.
> With this patch the tests still often hang (because of HARMONY-5247).
> But almost all 'build test' tests pass for me on Windows when they do not hang.
> I still have a problem with loading gc_cc library on Linux (tl::MemoryPoolMT can't be
found).
> Also outofemory.Int still fails on x86_64.
> I'll try to fix these remaining problems and update the patch.
