0a, 5a, 6a, 8a, 9a, ka, qa, va - assemblers 8a [ option ... ] [ name ... ]

etc.

These programs assemble the named files into object files for the corresponding architectures; see 8c (1) for the correspondence between an architecture and the character ( 6 , 8 , etc.) that specifies it. The assemblers handle the most common C preprocessor directives and the associated command-line options -D and -I . Other options are:

-o " obj" Place output in file obj (allowed only if there is just one input file). Default is to take the last element of the input path name, strip any trailing .s , and append . O , where O is first letter of the assembler's name.

The directory /sys/include is searched for include files after machine-dependent files in /$objtype/include . /sys/src/cmd/8a , etc. 8c (1), 8l (1).
