Subject [jira] Commented: (HARMONY-2040) [drlvm][jit][x86_64] fix compilation and disable bbp on linux/x86_64
Date Wed, 01 Nov 2006 18:51:21 GMT
    [ http://issues.apache.org/jira/browse/HARMONY-2040?page=comments#action_12446351 ] 
Mikhail Fursov commented on HARMONY-2040:

Salikh I support disabling BBP for em64t in JIT.
The BBP problem looks trivial and if the build is fixed I can fix BBP tomorrow and reenable
it in a separate patch.
