        * gcc.dg/tree-ssa/alias-1.c: New test.
2005-04-11  Andrew Pinski  <pinskia@physics.uc.edu>

        * tree-ssa-alias.c (may_alias_p): If the variable
        is a global variable and the pointer is parameter
        and -fargument-noalias-global is used, then
        the pointer cannot alias the variable.
