-S  Stop after the stage of compilation proper; do not assemble.  The output is in the form of an
    assembler code file for each non-assembler input file specified.

    By default, the assembler file name for a source file is made by replacing the suffix .c, .i, etc.,
    with .s.

    Input files that don't require compilation are ignored.
