New Revision: 3609
Modified:
trunk/osprey/be/lno/lnopt_main.cxx
Log:
Fixed runtime regression in SPEC Leslie3d that was due the field Prefer_Fuse not
being initialized in an instance of the DO_LOOP_INFO class that was constructed
with:
DO_LOOP_INFO::DO_LOOP_INFO(DO_LOOP_INFO *dli, MEM_POOL *pool)
Also added:
Comments to caution developers about issue.
Other missing initializations, along with other cosmetic changes so
that one can visually compare the two constructors with tkdiff.
Reviewed and approved by Mei Ye.
Modified: trunk/osprey/be/lno/lnopt_main.cxx
