`.subsection NAME'
==================
This is one of the ELF section stack manipulation directives. The
others are `.section' (Note:Section), `.pushsection' (Note:PushSection), `.popsection' (Note:PopSection), and `.previous'
(Note:Previous).
This directive replaces the current subsection with `name'. The
current section is not changed. The replaced subsection is put onto
the section stack in place of the then current top of stack subsection.
