To facilitate writing code that copies itself from one location to
another (e.g. from its LMA to its VMA during execution), the bin
object format provides several special symbols for every defined
section. Each special symbol begins with section.
followed
by the section name. The supported special bin
symbols
are:
section.sectname
.start
sectname
.section.sectname
.vstart
sectname
.section.sectname
.length
sectname
. The length is considered the runtime length, so
“nobits` sections” length is
their runtime length, not 0.
