zcc(1) C Compiler for Z8000 zcc(1)

NAME
|
||
|
||
zcc - C compiler
|
||
|
||
|
||
SYNOPSIS
|
||
|
||
zcc [ option ] ... file ...
|
||
|
||
|
||
DESCRIPTION
|
||
|
||
zcc is a fast optimizing C compiler. Its interface is nearly
|
||
completely compatible with most UNIX C compilers though there
|
||
are substantial differences in internal strategy. The language
|
||
supported is that of the Kernighan and Ritchie book referenced
|
||
below with the addition of field initialization and structure
|
||
assignment.
|
||
|
||
zcc is capable of operating in several modes. It can generate
|
||
code for both the Z8001 (segmented) and the Z8002 (non-
|
||
segmented) versions of the Z8000. See the -m option for de-
|
||
tails.
|
||
|
||
zcc accepts several types of arguments: Arguments whose names
|
||
end with `.c' are taken to be C source programs; they are com-
|
||
piled, and each object program is left on the file whose name is
|
||
that of the source with `.o' substituted for `.c'. Under CP/M,
|
||
only one C source file may be compiled per execution of zcc.
|
||
|
||
The following options are interpreted by zcc:
|
||
|
||
-c Suppress the loading phase of the compilation, and force
|
||
an object file to be produced even if only one program
|
||
is compiled.
|
||
|
||
-m<digit>
|
||
This is used to set the mode of the compiler. The digit
|
||
is interpreted in the following way:
|
||
|
||
0 - Z8001, 16 bit ints, 32 bit pointers, x.out output
|
||
1 - Z8002, 16 bit ints, 16 bit pointers, x.out output (default)
|
||
2 - Z8002, 16 bit ints, 32 bit pointers, x.out output
|
||
|
||
-w Suppress most of the warning messages in the compiler.
|
||
This turns off stringent type checking that is now
|
||
fashionable.
|
||
|
||
-s Compile the named C programs, and leave pseudo-assembly
|
||
language output on corresponding files suffixed `.s'.
|
||
As cc8k generates binary load modules directly without
|
||
an intermediate assembly language representation, this
|
||
option produces a disassembly listing of the generated

|

|

|
||
code.
|
||
|
||
-o output Name the final output file _o_u_t_p_u_t. If this op-
|
||
tion is used the file `x.out' will be left undisturbed.
|
||
|
||
-d name=def
|
||
-d name
|
||
Define the _n_a_m_e to the preprocessor, as if by `#define'.
|
||
If no definition is given, the name is defined as 1.
|
||
|
||
-u name
|
||
Remove any initial definition of _n_a_m_e.
|
||
|
||
-[0123]string
|
||
Pass _s_t_r_i_n_g as debug flags to subsequent passes of the
|
||
compiler. Flags for pass one begin with the digit `1';
|
||
flags for pass two with `2', and so forth. The digit
|
||
`0' is used for debug flags to the _z_c_c control program
|
||
itself. Flags for multiple passes may be concatenated.

DIAGNOSTICS
|
||
|
||
The diagnostics produced by C itself are intended to be
|
||
self-explanatory.
|
||
|
||
|
||
BUGS
|
||
|
||
No support for unsigned types other than short integers.
