Using Mapfiles
Changing Mapfiles with -k filename and +nodefaultmap
Changing Mapfiles with -k filename and
+nodefaultmap
The +nodefaultmap option used with -k option prevents the linker
from concatenating the default memory map to the map provided by
filename. If you specify +nodefaultmap, the linker does not append the
default mapfile to your mapfile. If you do not specify +nodefaultmap
with -k, the linker appends the default to the output file.
Mapfile Example: Using -k mapfile and
+nodefaultmap
