Typedef Documentation

typedef int alias_set_type

The type of an alias set.  Code currently assumes that variables of
   this type can take the values 0 (the alias set which aliases
   everything) and -1 (sometimes indicating that the alias set is
   unknown, sometimes indicating a memory barrier) and -2 (indicating
   that the alias set should be set to a unique value but has not been
   set yet).
