9.2.13 --force-link
Force linking of objects that may not be compatible.
If a target processor has been specified with the -p,--processor
option, the linker will compare it to information contained in the objects combined during the link. If a possible conflict is detected, an error (i.e., in the case of a possible instruction set incompatibility) or a warning (i.e., in the case of possible register incompatibility) will be reported. Specify this option to override such errors or warnings.
