New Revision: 3689
Modified:
trunk/osprey/be/opt/opt_htable.cxx
Log:
Re-patch rev 3688 and re-fix bug 830.
Add_idef() is used for both ILOAD and ISTORE. For ISTORE, the lbase is NULL but
previous patch doesn't check that. Also, previous patch doesn't work for store
to constant address like:
*(int*)0xffffffffffff8001 = val;
The new patch checks if the lbase or sbase is NULL and works for both
ILOAD/ISTORE to constant address.
Approved by Sun Chan.
