Written june 1987 by Ceriel J.H. Jacobs, partly derived from old

cc-driver, written by Erik Baalbergen.

this language is called, which passes must be called, which flags

and arguments must be passed to these passes, etc.
|
||

|
The language is determined by the suffix of the argument program.

However, if this suffix does not determine a language (DEFLANG),

the callname is used.
|

Notice that the 's' suffix does not determine a language, because
|

the input file could have been derived from f.i. a C-program.
|

|
|
So, if you use "cc x.s", the C-runtime system will be used, but if
|

|
you use "as x.s", it will not.
