4.12 Placing sections with FIRST and LAST attributes

Image structure and generation
You can make sure that a section is placed either first or last in its execution region. For example,
you might want to make sure the section containing the vector table is placed first in the image.
To do this, use one of the following methods:
• If you are not using scatter-loading, use the --first and --last linker command-line
options to place input sections.
• If you are using scatter-loading, use the attributes FIRST and LAST in the file to mark the
first and last input sections in an execution region if the placement order is important.
However, FIRST and LAST must not violate the basic attribute sorting order. For example,
FIRST RW is placed after any read-only code or read-only data.
