ARM Compiler armlink User Guide : --muldefweak, --no_muldefweak

--muldefweak, --no_muldefweak

Enables or disables multiple weak definitions of a symbol.


If enabled, the linker chooses the first definition that it encounters and discards all the other duplicate definitions. If disabled, the linker generates an error message for all multiply defined weak symbols.


The default is --muldefweak.
