Assembler Directives

   All assembler directives have names that begin with a period (`.').
The rest of the name is letters, usually in lower case.
   This chapter discusses directives that are available regardless of
the target machine configuration for the GNU assembler.  Some machine
configurations provide additional directives.  *Note Machine
