/* Linkers may treat weak functions differently if they are located within
|
|
* the same object that calls the symbol or not.
|
|
*
|
|
* For example, when using armlink, then if the weak symbol is inside the object
|
|
* referring to it the weak symbol will be used. This will result in the symbol
|
|
* being multiply defined because both the weak and strong symbols are used.
|
|
*
|
|
* To GNU ld, it doesn't matter if the weak symbol is placed in the same object
|
|
* which uses the weak symbol. GNU ld will always link to the strong version.
|
|
*
|
|
* Having the weak main symbol in an independent file ensures that it will be
|
|
* correctly treated by multiple linkers.
