Hello All:
Gatekeepers could you please review the fix for bug ID 739 and 723.
Following files are modified
Osprey/wgen/wgen_expr.cxx
osprey/be/com/opt_cvtl_rule.cxx
osprey/be/opt/opt_emit_template.h
The changes are made not to emit CVT for types vectors is not needed and also
to keep CVT generated
By LNO. Changes also made to check for gs_decl_initial if VAR_DECL is found for
copy -1 preg to temp area.
