           Product: lld
           Version: unspecified
          Hardware: PC
                OS: Windows NT

The -defsym option of ld is a useful feature both for symbol renaming e.g.

-defsym=__vfprintf=__vfprintf_float_long_long

and to specify addresses at link time e.g.

-defsym=UART=0x20004000
