7. 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. See section 8. Machine Dependent Features.
