Node:Previous, Next:Print, Previous:PopSection, Up:Pseudo Ops

### `.previous`

This is one of the ELF section stack manipulation directives. The others are `.section` (see Section), `.subsection` (see SubSection), `.pushsection` (see PushSection), and `.popsection` (see PopSection).

This directive swaps the current section (and subsection) with most recently referenced section (and subsection) prior to this one. Multiple `.previous` directives in a row will flip between two sections (and their subsections).

In terms of the section stack, this directive swaps the current section with the top section on the section stack.
