3.6.8.1 Output section type

Each output section may have a type. The type is a keyword in parentheses. The following types are defined:

NOLOAD
The section should be marked as not loadable, so that it will not be loaded into memory when the program is run.
DSECT
COPY
INFO
OVERLAY
These type names are supported for backward compatibility, and are rarely used. They all have the same effect: the section should be marked as not allocatable, so that no memory is allocated for the section when the program is run.

The linker normally sets the attributes of an output section based on the input sections which map into it. You can override this by using the section type. For example, in the script sample below, the `ROM' section is addressed at memory location `0' and does not need to be loaded when the program is run. The contents of the `ROM' section will appear in the linker output file as usual.
 
SECTIONS {
  ROM 0 (NOLOAD) : { ... }
  ...
}
