Enabling this option can have a dramatic effect on load and link times of a DSO as it massively reduces the size of the dynamic export table when the library makes heavy use of templates. +The behaviour of this switch is not quite the same as marking the +methods as hidden directly, because it does not affect static variables +local to the function or cause the compiler to deduce that +the function is defined in only one shared object. + You may mark a method as having a visibility explicitly to negate the effect of the switch for that method. For example, if you do want to -compare pointers to a particular inline method, or the method has -local static data, you might mark it as having default visibility. +compare pointers to a particular inline method, you might mark it as +having default visibility. @item -fno-weak @opindex fno-weak |
