    * varasm.c (compute_visible_aliases): New function.
    (remove_unreachable_alias_pairs): Aliases make a target available
    even though we reclaimed the cgraph node.
    (finish_aliases_1): Likewise.
    * Makefile.in (varasm.o): Add pointer-set.h dependency.

    * gcc.target/i386/alias-1.c: New testcase.
