We showed above that the full description of an output section looked like this:
section [address] [(type)] :
[AT(lma)] [ALIGN(section_align)] [SUBALIGN(subsection_align)]
{
output-section-command
output-section-command
...
} [>region] [AT>lma_region] [:phdr :phdr ...] [=fillexp]
We've already described section, address, and output-section-command. In this section we will describe the remaining section attributes.
