NAME
0a, 1a, 2a, 5a, 6a, 8a, ka, qa, va – assemblers

SYNOPSIS
2a [ option ... ] [ name ... ]
etc.

DESCRIPTION
These programs assemble the named files into object files for the corresponding architectures; see 2c(1) for the correspondence between an architecture and the character (1, 2, 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.

FILES
The directory /sys/include is searched for include files after machine–dependent files in /$objtype/include.

SOURCE
/sys/src/cmd/2a, etc.

SEE ALSO
2c(1), 2l(1).

BUGS
The list of assemblers given above is only partial, not all architectures are supported on all systems, some have been retired and some are provided by third parties.
