with the following commands available:

group

Group attributes:
BSS group is unitialised data

Remarks
•• Sections within a group are in the order that section definitions are encountered
in the command file or object/library files.
• Any sections that are not placed in a specified group will be grouped together at
the beginning of the output.
• Groups are output in the order in which they are declared in the Linker command
file or the order in which they are encountered in the object and library files.
• Sections which are declared with attributes, (i.e. not in a group) in either the
object or library files, may be put into a specified group by the appropriate
declaration in the Linker command file.
