6 Assembling Your Program
This chapter describes two different ways you can invoke the Assembler
and the various command line options controlling its behavior. It also
contains a brief description of the interface between the Assembler and
linker, and things you should remember to facilitate the running of an
assembly program.
Invoking the Assembler
You can invoke the Assembler directly by using the as command. Or, you
can invoke the Assembler through the cc command, which processes the
assembly source using the C preprocessor. The next two sections describe
these pathways.
