11.28 --execstack, --no_execstack

Generates a .note.GNU-stack section marking the stack as either executable or non-executable.

You can also use the AREA directive to generate either an executable or non-executable .note.GNU-stack section. The following code generates an executable .note.GNU-stack section. Omitting the CODE attribute generates a non-executable .note.GNU-stack section.

    AREA    |.note.GNU-stack|,ALIGN=0,READONLY,NOALLOC,CODE

In the absence of --execstack and --no_execstack, the .note.GNU-stack section is not generated unless it is specified by the AREA directive.

If both the command-line option and source directive are used and are different, then the stack is marked as executable.
