<abstract>
cc65 is a C compiler for 6502 targets. It supports several old 6502 based home
computers like the Commodore and Atari machines, but it is easily retargetable.
</abstract>
<!-- Table of contents -->
<toc>
<!-- Begin the document -->
<sect>Overview<p>
cc65 was originally a C compiler for the Atari 8-bit machines written by
John R. Dunning. In prior releases I've described the compiler by listing
up the changes made by me. I have made many more changes in the meantime
(and rewritten major parts of the compiler), so I will no longer do that,
since the list would be too large and of no use to anyone. Instead I will
describe the compiler in respect to the ANSI/ISO C standard. In fact, I'm
planning a complete rewrite (that is, a complete new compiler) for the
next release, since there are too many limitations in the current code,
and removing these limitations would mean a rewrite of many more parts of
the compiler.
There is a separate document named "library.txt" that covers the library
available for the compiler. If you know C and are interested in doing
actual programming, the library documentation is probably of much more use
than this document.
If you need some hints for getting the best code out of the compiler, you
may have a look at "coding.txt" which covers some code generation issues.
<sect>Usage<p>
The compiler translates C files into files containing assembler code that
may be translated by the ca65 macroassembler (for more information about
the assembler, have a look at ca65.txt).
The compiler may be called as follows:
<tscreen><verb>

---------------------------------------------------------------------------
</verb></tscreen>
Here is a description of all the command line options:
<descrip>
<tag><tt>-A, --ansi</tt></tag>
This option disables any compiler exensions. Have a look at section 5
for a discussion of compiler extensions. In addition, the macro
<verb>
__STRICT_ANSI__
</verb>
is defined, when using one of these options.
<tag><tt>--cpu CPU</tt></tag>
A new, still experimental option. You may specify "6502" or "65C02" as
the CPU. 6502 is the default, so this will not change anything.
Specifying 65C02 will use a few 65C02 instructions when generating code.
Don't expect too much from this option: It is still new (and may have
bugs), and the additional instructions for the 65C02 are not that
overwhelming.
<tag><tt>-d, --debug</tt></tag>
Enables debug mode, something that should not be needed for mere
mortals:-)
<tag><tt>-D sym[=definition]</tt></tag>
Define a macro on the command line. If no definition is given, the macro
is defined to the value "1".
<tag><tt>-g, --debug-info</tt></tag>
This will cause the compiler to insert a .DEBUGINFO command into the
generated assembler code. This will cause the assembler to include all
symbols in a special section in the object file.
<tag><tt>-h, --help</tt></tag>
Print the short option summary shown above.
<tag><tt>-j, --signed-chars</tt></tag>
Using this option, you can make the default characters signed. Since the
6502 has no provisions for sign extending characters (which is needed on
almost any load operation), this will make the code larger and slower. A
better way is to declare characters explicitly as "signed" if needed.
You can also use "#pragma signedchars" for better control of this option
(see section 7).
<tag><tt>-t target, --target target</tt></tag>
This option is used to set the target system. The target system
determines things like the character set that is used for strings and
character constants. The following target systems are supported:
none
c64
c128
ace (no library support)
plus4
cbm610
pet (all CBM PET systems except the 2001)
nes (Nintendo Entertainment System)
apple2
geos
<tag><tt>-v, --verbose</tt></tag>
Using this option, the compiler will be somewhat more verbose if errors
or warnings are encountered.
<tag><tt>-Cl, --static-locals</tt></tag>
Use static storage for local variables instead of storage on the stack.
Since the stack is emulated in software, this gives shorter and usually
faster code, but the code is no longer reentrant. The difference between
-Cl and declaring local variables as static yourself is, that
initializer code is executed each time, the function is entered. So when
using
void f (void)
{
unsigned a = 1;
...
}
the variable a will always have the value 1 when entering the function
and using -Cl, while in
void f (void)
{
static unsigned a = 1;
....
}
the variable a will have the value 1 only the first time, the function
is entered, and will keep the old value from one call of the function to
the next.
You may also use #pragma staticlocals to change this setting in your
sources (see section 7).
<tag><tt>-I dir, --include-dir dir</tt></tag>
Set a directory where the compiler searches for include files. You may
use this option multiple times to add more than one directory to the
search list.
<tag><tt>-o name</tt></tag>
Specify the name of the output file. If you don't specify a name, the
name of the C input file is used, with the extension replaced by ".s".
<tag><tt>-O, -Oi, -Or, -Os</tt></tag>
Enable an optimizer run over the produced code.
Using -Oi, the code generator will inline some code where otherwise a
runtime functions would have been called, even if the generated code is
larger. This will not only remove the overhead for a function call, but
will make the code visible for the optimizer.
-Or will make the compiler honor the "register" keyword. Local variables
may be placed in registers (which are actually zero page locations).
There is some overhead involved with register variables, since the old
contents of the registers must be saved and restored. In addition, the
current implementation does not make good use of register variables, so
using -Or may make your program even slower and larger. Use with care!
Using -Os will force the compiler to inline some known functions from
the C library like strlen. Note: This has two consequences:
* You may not use names of standard C functions in your own code. If
you do that, your program is not standard compliant anyway, but
using -Os will actually break things.
* The inlined string and memory functions will not handle strings or
memory areas larger than 255 bytes. Similar, the inlined is..()
functions will not work with values outside char range.
It is possible to concatenate the modifiers for -O. For example, to
enable register variables and inlining of known functions, you may use
-Ors.
<tag><tt>-T</tt></tag>
This include the source code as comments in the generated code. This is
normally not needed.
<tag><tt>-V, --version</tt></tag>
Print the version number of the compiler. When submitting a bug report,
please include the operating system you're using, and the compiler
version.
<tag><tt>-W</tt></tag>
This option will suppress any warnings generated by the compiler. Since
any source file may be written in a manner that it will not produce
compiler warnings, using this option is usually not a good idea.
</descrip><p>
<sect>Input and output<p>
The compiler will accept one C file per invocation and create a file with
the same base name, but with the extension replaced by ".s". The output
file contains assembler code suitable for the use with the ca65 macro
assembler.
In addition to the paths named in the -I option on the command line, the
directory named in the environment variable CC65_INC is added to the
search path for include files on startup.
<sect>Differences to the ISO standard<p>
Here is a list of differences between the language, the compiler accepts,
and the one defined by the ISO standard:
<itemize>
<item> The compiler allows single line comments that start with //. This
feature is disabled in strict ANSI mode.
<item> The compiler allows unnamed parameters in parameter lists. The
compiler will not issue warnings about unused parameters that don't
have a name. This feature is disabled in strict ANSI mode.
<item> The compiler has some additional keywords:<p>
<tt/asm/, <tt/__asm__/, <tt/fastcall/, <tt/__fastcall__/, <tt/__AX__/,
<tt/__EAX__/, <tt/__func__/, <tt/__attribute__/
<p>
The keywords without the underlines are disabled in strict ANSI mode.
<item> The datatypes "float" and "double" are not available.
<item> The compiler does not support bit fields.
<item> Initialization of local variables is only possible for scalar data
types (that is, not for arrays and structs).
<item> Because of the "wrong" order of the parameters on the stack, there is
an additional macro needed to access parameters in a variable
parameter list in a C function.
<item> Functions may not return structs. However, struct assignment *is*
possible.
<item> Part of the C library is available only with fastcall calling
conventions (see below). This means, that you may not mix pointers to
those functions with pointers to user written functions.
</itemize>
There may be some more minor differences, I'm currently not aware off. The
biggest problem is the missing float data type. With this limitation in
mind, you should be able to write fairly portable code.
<sect>Extensions<p>
This cc65 version has some extensions to the ISO C standard.
<itemize>
<item> The compiler allows // comments (like in C++ and in the proposed C9x
standard). This feature is disabled by <tt/-A/.
<item> The compiler allows to insert assembler statements into the output
file. The syntax is
<p>
<tt/asm (&lt;string literal&gt;) ;/
<p>
or
<p>
<tt/__asm__ (&lt;string literal&gt;) ;/
<p>
The first form is in the user namespace and is disabled if the <tt/-A/
switch is given.
The given string is inserted literally into the output file, and a
newline is appended. The statements in this string are not checked by
the compiler, so be careful!
The asm statement may be used inside a function and on global file
level.
<item> There is a special calling convention named "fastcall". This calling
convention is currently only usable for functions written in
assembler. The syntax for a function declaration using fastcall is
<p>
&lt;return type&gt; fastcall &lt;function name&gt; (&lt;parameter list&gt;)
<p>
or
<p>
&lt;return type&gt; __fastcall__ &lt;function name&gt; (&lt;parameter list&gt;)
<p>
An example would be
<tscreen><verb>
void __fastcall__ f (unsigned char c)
</verb></tscreen>
The first form of the fastcall keyword is in the user namespace and is
therefore disabled in strict ANSI mode.
For functions declared as <tt/fastcall/, the rightmost parameter is not
pushed on the stack but left in the primary register when the function
is called. This will reduce the cost when calling assembler functions
significantly, especially when the function itself is rather small.
<item> There are two pseudo variables named <tt/__AX__/ and <tt/__EAX__/.
Both refer to the primary register that is used by the compiler to
evaluate expressions or return function results. <tt/__AX__/ is of
type <tt/unsigned int/ and <tt/__EAX__/ of type <tt/long unsigned int/
respectively. The pseudo variables may be used as lvalue and rvalue as
every other variable. They are most useful together with short
sequences of assembler code. For example, the macro
<tscreen><verb>
#define hi(x) (__AX__=(x),asm("\ttxa\n\tldx\t#$00",__AX__)
</verb></tscreen>
will give the high byte of any unsigned value.
<item> Inside a function, the identifier <tt/__func__/ gives the name of the
current function as a string. Outside of functions, <tt/__func__/ is
undefined.
Example:
<tscreen><verb>
#define PRINT_DEBUG(s) printf ("%s: %s\n", __func__, s);
</verb></tscreen>
The macro will print the name of the current function plus a given
string.
</itemize>
<p>
<sect>Predefined macros<p>
The compiler defines several macros at startup:
<descrip>
<tag><tt>__CC65__</tt></tag>
This macro is always defined. Its value is the version number of the
compiler in hex. Version 2.0.1 of the compiler will have this macro defined
as 0x0201.
<tag><tt>__CBM__</tt></tag>
This macro is defined if the target system is one of the CBM targets.
<tag><tt>__C64__</tt></tag>
This macro is defined if the target is the c64 (-t c64).
<tag><tt>__C128__</tt></tag>
This macro is defined if the target is the c128 (-t c128).
<tag><tt>__PLUS4__</tt></tag>
This macro is defined if the target is the plus/4 (-t plus4).
<tag><tt>__CBM610__</tt></tag>
This macro is defined if the target is one of the CBM 600/700 family of
computers (called B series in the US).
<tag><tt>__PET__</tt></tag>
This macro is defined if the target is the PET family of computers (-t pet).
<tag><tt>__ATARI__</tt></tag>
This macro is defined if the target is one of the Atari computers
(400/800/130XL/800XL). Note that there is no runtime and C library support
for atari systems.
<tag><tt>__APPLE2__</tt></tag>
This macro is defined if the target is the Apple ][ (-t apple2).
<tag><tt>__GEOS__</tt></tag>
This macro is defined if you are compiling for the GEOS system (-t geos).
<tag><tt>__FILE__</tt></tag>
This macro expands to a string containing the name of the C source file.
<tag><tt>__LINE__</tt></tag>
This macro expands to the current line number.
<tag><tt>__STRICT_ANSI__</tt></tag>
This macro is defined to 1 if the -A compiler option was given, and
undefined otherwise.
<tag><tt>__OPT__</tt></tag>
Is defined if the compiler was called with the -O command line option.
<tag><tt>__OPT_i__</tt></tag>
Is defined if the compiler was called with the -Oi command line option.
<tag><tt>__OPT_r__</tt></tag>
Is defined if the compiler was called with the -Or command line option.
<tag><tt>__OPT_s__</tt></tag>
Is defined if the compiler was called with the -Os command line option.
</descrip>
<sect>#pragmas<p>
The compiler understands some pragmas that may be used to change code
generation and other stuff.
<descrip>
<tag><tt>#pragma bssseg (&lt;name&gt;)</tt></tag>
This pragma changes the name used for the BSS segment (the BSS segment
is used to store uninitialized data). The argument is a string enclosed
in double quotes.
Note: The default linker configuration file does only map the standard
segments. If you use other segments, you have to create a new linker
configuration file.
Beware: The startup code will zero only the default BSS segment. If you
use another BSS segment, you have to do that yourself, otherwise
uninitialized variables do not have the value zero.
Example:
#pragma bssseg ("MyBSS")
<tag><tt>#pragma codeseg (&lt;name&gt;)</tt></tag>
This pragma changes the name used for the CODE segment (the CODE segment
is used to store executable code). The argument is a string enclosed in
double quotes.
Note: The default linker configuration file does only map the standard
segments. If you use other segments, you have to create a new linker
configuration file.
Example:
#pragma bssseg ("MyCODE")
<tag><tt>#pragma dataseg (&lt;name&gt;)</tt></tag>
This pragma changes the name used for the DATA segment (the DATA segment
is used to store initialized data). The argument is a string enclosed in
double quotes.
Note: The default linker configuration file does only map the standard
segments. If you use other segments, you have to create a new linker
configuration file.
Example:
#pragma bssseg ("MyDATA")
<tag><tt>#pragma rodataseg (&lt;name&gt;)</tt></tag>
This pragma changes the name used for the RODATA segment (the RODATA
segment is used to store readonly data). The argument is a string
enclosed in double quotes.
Note: The default linker configuration file does only map the standard
segments. If you use other segments, you have to create a new linker
configuration file.
Example:
#pragma bssseg ("MyRODATA")
<tag><tt>#pragma regvaraddr (&lt;const int&gt;)</tt></tag>
The compiler does not allow to take the address of register variables.
The regvaraddr pragma changes this. Taking the address of a register
variable is allowed after using this pragma, if the argument is not
zero. Using an argument of zero changes back to the default behaviour.
Beware: The C standard does not allow taking the address of a variable
declared as register. So your programs become non-portable if you use
this pragma. In addition, your program may not work. This is usually the
case if a subroutine is called with the address of a register variable,
and this subroutine (or a subroutine called from there) uses itself
register variables. So be careful with this #pragma.
Example:
#pragma regvaraddr(1) /* Allow taking the address
* of register variables
*/
<tag><tt>#pragma signedchars (&lt;const int&gt;)</tt></tag>
Changed the signedness of the default character type. If the argument
is not zero, default characters are signed, otherwise characters are
unsigned. The compiler default is to make characters unsigned since this
creates a lot better code.
<tag><tt>#pragma staticlocals (&lt;const int&gt;)</tt></tag>
Use variables in the bss segment instead of variables on the stack. This
pragma changes the default set by the compiler option -Cl. If the argument
is not zero, local variables are allocated in the BSS segment, leading to
shorter and in most cases faster, but non-reentrant code.
<tag><tt>#pragma zpsym (&lt;name&gt;)</tt></tag>
Tell the compiler that the - previously as external declared - symbol with
the given name is a zero page symbol (usually from an assembler file).
The compiler will create a matching import declaration for the assembler.
Example:
extern int foo;
#pragma zpsym ("foo"); /* foo is in the zeropage */

In acknowledgment of this copyright, I will place my own changes to the
compiler under the same copyright. Please note however, that the library
and all binutils are covered by another copyright, and that I'm planning
to do a complete rewrite of the compiler, after which the compiler
copyright will also change.
For the list of changes requested by this copyright see newvers.txt.
