        !            40: .Nm as
        !            41: assembler produces an object file from the given source files
        !            42: or from the standard input.
        !            43: .Tp Fl a
        !            44: Specifies the alignment
        !            45: .Ar value
        !            46: of procedures and data blocks.
        !            47: It is given as a power of two; thus an alignment of 3
        !            48: causes alignment on an eight byte boundary.
        !            49: The default is

        !            60: not defined in the first pass or unspecified in the assembly language.
        !            61: Possible values are

        !            76: to save space in the resultant symbol table.
        !            77: The compilers generate such temporary labels.
        !            78: .Tp Fl V
        !            79: Use virtual memory for some intermediate storage,
        !            80: rather than a temporary file.
        !            81: .Tp Fl W

        !            85: insufficient.  This must be used when a compiler-generated assembly contains
        !            86: branches of more than 32k bytes.
        !            87: .Tp Fl R
        !            88: Make initialized data segments read-only, by concatenating them to
        !            89: the text segments.
        !            90: This obviates the need to run editor scripts on assembly
        !            91: code to make initialized data read-only and shared.
        !            92: .Tp Fl t
        !            93: Specifies a directory to receive the temporary file, other than
        !            94: the default /tmp.
