Like most compilation systems, the TDF C system consists of a number
|
|
|
29 |
of components which transform or combine various types of input files
|
|
|
30 |
into output files. <CODE>tcc</CODE> is designed to be a compilation
|
|
|
31 |
manager, coordinating these various components into a coherent compilation
|
|
|
32 |
scheme. It is also the normal user's interface to the TDF system on
|
|
|
33 |
Unix machines: direct use of the various components of the system
|
|
|
34 |
is not recommended. Therefore it is worth familiarising oneself with
|
|
|
35 |
<CODE>tcc</CODE> before attempting to use the TDF system. To aid this
|
|
|
36 |
familiarisation <CODE>tcc</CODE> has been designed to have the same
|
|
|
37 |
look and feel as the system C compiler <CODE>cc</CODE>, but with added
|
|
|
38 |
functionality to deal with the additional features of the TDF system.
|
|
|
39 |
This does not mean that <CODE>tcc</CODE> can be necessarily regarded
|
|
|
40 |
as a direct replacement for <CODE>cc</CODE> ; the extra portability
|
|
|
41 |
checks performed by the TDF system require the precise compilation
|
|
|
42 |
environment to be specified to <CODE>tcc</CODE> in a way that it cannot
|
|
|
43 |
be to <CODE>cc</CODE>.<P>
|
|
|
44 |
There are two basic components to this paper. The first describes
|
|
|
45 |
the TDF compilation strategy and how it is implemented by <CODE>tcc</CODE>.
|
|
|
46 |
The second is a Quick Reference section at the end of the paper, which
|
|
|
47 |
is intended to be a <CODE>tcc</CODE> user's manual. For even quicker
|
|
|
48 |
reference, <CODE>tcc</CODE> will print a list of all its command-line
|
|
|
49 |
options (with a brief description) if invoked with the <B>-query</B>
|
|
|
50 |
option.<P>
