Values starting with 0 are always interpreted as numerical values. |
- | If the specified symbol name is a C variable name, add "_" at the head of the definition name in the program. |
[Example of use]
- | To define "_sym1" as the same value as external defined symbol "data", describe as: |
>rlink -define=_sym1=data a.obj b.obj
|
- | To define "_sym2" as 0x4000, describe as: |
>rlink -define=_sym2=4000 a.obj b.obj
