Contributing to cc65
====================
(''Note:'' The word "must" indicates a requirement. The word "should" indicates a recomendation.)
This document contains all kinds of information that you
should know if you want to contribute to the cc65 project.
Before you start, please read all of it. If something is not
clear to you, please ask - this document is an ongoing effort
and may well be incomplete.
*this is work in progress and is constantly updated - if in doubt, please ask*
Also, before you put a lot of work into implementing
something you want to contribute, please get in touch with
one of the developers and ask if what you are going to do is
actually wanted and has a chance of being merged. Perhaps
someone else is already working on it, or perhaps what you
have in mind is not how we'd expect it to be - talking to us
before you start might save you a lot of work in those cases.
# generally
(''Note:'' The word "must" indicates a requirement. The word
"should" indicates a recomendation.)
* You must obey these rules when contributing new code or documentation to cc65. We are well aware that not all existing code may respect all rules outlined here - but this is no reason for you not to respect them.
* One commit/patch/PR per issue. Do not mix several things unless they are very closely related.
* Sometimes when you make a PR, it may break completely unrelated tests. However, any PR is expected to merge cleanly with no failures. That means in practise that you are expected to fix/update the failing tests if required - for example this might be needed if you make changes to the compiler that changes the format of error- or warning messages. In that case you might have to update some reference files in the testbench. Obviously still check if that is actually the right thing to do ;)

### Identifiers and Symbol names
### Identifiers and symbol names
The C Standard defines certain identifiers and symbol names, which we can not use
in our code. Since it is not always obvious which parts of the library code will
actually end up in a linked program, the following applies to ALL of the library.

This is likely more than the standard dictates us to do - but it is certainly
standard compliant - and easy to remember.

* 80 characters is the desired maximum width of files. But, it isn't a "strong" rule; sometimes, you will want to type longer lines, in order to keep the parts of expressions or comments together on the same line.

longer lines, in order to keep the parts of expressions or
comments together on the same line.
* You should avoid typing non-ASCII characters.
* If you change "normal" source code into comments, then you must add a comment about why that code is a comment.
* When you want to create a comment from several lines of code, you should use preprocessor lines, instead of ```/* */``` or "```;```". Example:

three = two () + one ();
one (); two ();

* You should type upper case characters for hex values.
* When you type zero-page addresses in hexadecimal, you should type two hex characters (after the hex prefix). When you type non-zero-page addresses in hex, you should type four hex characters.
* When you type lists of addresses, it is a good idea to sort them in ascending numerical order. That makes it easier for readers to build mental pictures of where things are in an address space. And, it is easier to see how big the variables and buffers are. Example:

The following is still very incomplete - if in doubt please

* Your files should generally obey the C89 standard, with a few C99 things (this is a bit similar to what cc65 itself supports). The exceptions are:
* use stdint.h for variables that require a certain bit size
* In printf-style functions use the PRIX64 (and similar) macros to deal with 64bit values (from inttypes.h)
This list is not necessarily complete - if in doubt, please ask.

* We generally have a "no warnings" policy
* Warnings must not be hidden by using typecasts - fix the code instead
* Warnings must not be hidden by using typecasts - fix the

* The normal indentation width should be four spaces.
* You must use ANSI C comments (```/* */```); you must not use C++ comments (```//```).
* When you add functions to an existing file, you should separate them by the same number of blank lines that separate the functions that already are in that file.
* All function declarations must be followed by a comment block that tells at least briefly what the function does, what the parameters are, and what is returned. This comment must sit between the declaration and the function body, like this:

/* Add 1 to bar, takes bar and returns the result */
{
return bar + 1;
}
</pre>
* When a function's argument list wraps around to a next line, you should indent that next line by either the normal width or enough spaces to align it with the arguments on the previous line.
* All declarations in a block must be at the beginning of that block.
* You should put a blank line between a list of local variable declarations and the first line of code.
* Always use curly braces even for single statements after ```if```, and the single statement should go into a new line.
* Use "cuddling" braces, ie the opening brace goes in the same line as the ```if```:

### Header files
Headers that belong to the standard library (libc) must conform with the C standard. That means:
* all non standard functions, or functions that only exist in a certain standard, should be in #ifdefs
* the same is true for macros or typedefs
<pre>
#if __CC65_STD__ == __CC65_STD_C99__
/* stuff that only exists in C99 here */
#endif
#if __CC65_STD__ == __CC65_STD_CC65__
/* non standard stuff here */
#endif
</pre>
You can refer to Annex B of the ISO C99 standard ([here](https://www.open-std.org/jtc1/sc22/wg14/www/docs/n1256.pdf) is the draft).
* All Headers should start with a copyright/license banner
* Function prototypes must be a single line, not contain the redundant
"extern" keyword, and followed by a brief comment that explains what
the function does, and separated from the next prototype by a blank
line:
## Assembly Sources
~~~C
void __fastcall__ cclear (unsigned char length);
/* Clear part of a line (write length spaces). */
* Op-code mnemonics must have lower-case letters. The names of instruction macroes may have upper-case letters.
* Op-codes must use their official and commonly used mnemonics, ie bcc and bcs and not bgt and blt
* Hexadecimal number constants should be used except where decimal or binary numbers make much more sense in that constant's context.

* Hexadecimal number constants should be used except where
decimal or binary numbers make much more sense in that
constant's context.
* Hexadecimal letters should be upper-case.
* When you set two registers or two memory locations to an immediate 16-bit zero, you should use the expressions ```#<$0000``` and ```#>$0000``` (they make it obvious where you are putting the lower and upper bytes).
* If a function is declared to return a char-sized value, it actually must return an integer-sized value. (When cc65 promotes a returned value, it sometimes assumes that the value already is an integer.) This must be done in one of the following ways:

* Functions, that are intended for a platform's system library, should be optimized as much as possible.
* Sometimes, there must be a trade-off between size and speed. If you think that a library function won't be used often, then you should make it small. Otherwise, you should make it fast.
* Comments that are put on the right side of instructions must be aligned (start in the same character columns).
* Assembly source fields (label, operation, operand, comment) should start ''after'' character columns that are multiples of eight (such as 1, 9, 17, 33, and 41).

# Library implementation rules
* By default the toolchain must output a "standard" binary for the platform, no emulator formats, no extra headers used by tools. If the resulting binaries can not be run as is on emulators or eg flash cartridges, the process of converting them to something that can be used with these should be documented in the user manual.
* Generally every function should live in a seperate source file - unless the functions are so closely related that splitting makes no sense.
* Source files should not contain commented out code - if they do, there should be a comment that explains why that commented out code exists.

## People
Project founder:
cc65 is originally based on the "Small C" compiler by Ron Cain and
enhanced by James E. Hendrix.
* Ullrich von Bassewitz
### Project founders
Core team members:
* John R. Dunning: [original implementation](https://public.websites.umich.edu/~archive/atari/8bit/Languages/Cc65/)
of the C compiler and runtime library, Atari hosted.
* Ullrich von Bassewitz:
* moved Dunning's code to modern systems,
* rewrote most parts of the compiler,
* rewrote all of the runtime library.

<sect1>Unnamed labels<p>
If you really want to write messy code, there are also unnamed labels. These
labels do not have a name (you guessed that already, didn't you?). A colon is
used to mark the absence of the name.
If you really want to write messy code, there are also unnamed labels. To define
an unnamed label, use sole <tt>:</tt>.
Unnamed labels may be accessed by using the colon plus several minus or plus
characters as a label designator. Using the '-' characters will create a back
reference (use the n'th label backwards), using '+' will create a forward
reference (use the n'th label in forward direction). An example will help to
understand this:
To reference an unnamed label, use <tt>:</tt> with several <tt>-</tt> or <tt>+</tt> characters.
The <tt>-</tt> characters will create a back reference (n'th label backwards),
the <tt>+</tt> will create a forward reference (n'th label in forward direction).
As an alternative, angle brackets <tt>&lt;</tt> and <tt>&gt;</tt> may be used
instead of <tt>-</tt> and <tt>+</tt> with the same meaning.
Example:
<tscreen><verb>

As you can see from the example, unnamed labels will make even short
sections of code hard to understand, because you have to count labels
to find branch targets (this is the reason why I for my part do
prefer the "cheap" local labels). Nevertheless, unnamed labels are
convenient in some situations, so it's your decision.

Currently, members are just offsets from the start of the struct or union. To
Members are just offsets from the start of the struct or union. To
access a field of a struct, the member offset must be added to the address of
the struct variable itself:
<tscreen><verb>
lda C+Circle::Radius ; Load circle radius into A
lda C + Circle::Radius ; Load circle radius
lda C + Circle::Origin + Point::ycoord ; Load circle origin.ycoord
</verb></tscreen>
That may change in a future version of the assembler.
Nested structures or unions are treated differently depending on whether they
are anonymous. If named, a new structure definition is created within the
enclosing scope, with its offsets beginning at 0. If anonymous, the members of
the new structure are added to the enclosing scope instead, with offsets
continuing through that scope. Example:
<tscreen><verb>
.struct Object
id .byte ; Object::id = 0
target .struct Point ; Object::target = 1
xcoord .word ; Object::Point::xcoord = 0
ycoord .word ; Object::Point::ycoord = 2

; Be careful not to use a named nested structure without also adding the
; offset to the nested structure itself.
lda O + Object::Point::ycoord ; Incorrect!
lda O + Object::target + Object::Point::ycoord ; Correct
</verb></tscreen>
In this example, the first nested structure is named "Point", and its member
offsets begin at 0. On the other hand, the two anonymous structures simply
continue to add members to the enclosing "Object" structure.
Note that an anonymous structure does not need a member name, since all of its
members become part of the enclosing structure. The "cost" member in the
example is redundantly the same offset as its first member "price".

@@ -1180,6 +1180,202 @@ The ZPSAVE segment contains the original values of the zeropage locations used
by the ZEROPAGE segment. It is placed in its own segment because it must not be
initialized.
<sect>Debug Info<p>
The debug info and the API mirrors closely the items available in the sources
used to build an executable. To use the API efficiently, it is necessary to
understand from which blocks the information is built.
<itemize>
<item> Libraries
<item> Lines
<item> Modules
<item> Scopes
<item> Segments
<item> Source files
<item> Spans
<item> Symbols
<item> Types
</itemize>
Each item of each type has something like a primary index called an 'id'.
The ids can be thought of as array indices, so looking up something by its
id is fast. Invalid ids are marked with the special value CC65_INV_ID.
Data passed back for an item may contain ids of other objects. A scope for
example contains the id of the parent scope (or CC65_INV_ID if there is no
parent scope). Most API functions use ids to lookup related objects.
<sect1>Libraries<p>
This information comes from the linker and is currently used in only one
place:To mark the origin of a module. The information available for a library
is its name including the path.
<itemize>
<item> Library id
<item> Name and path of library
</itemize>
<sect1>Lines<p>
A line is a location in a source file. It is module dependent, which means
that if two modules use the same source file, each one has its own line
information for this file. While the assembler has also column information,
it is dropped early because it would generate much more data. A line may have
one or more spans attached if code or data is generated.
<itemize>
<item> Line id
<item> Id of the source file, the line is from
<item> The line number in the file (starting with 1)
<item> The type of the line: Assembler/C source or macro
<item> A count for recursive macros if the line comes from a macro
</itemize>
<sect1>Modules<p>
A module is actually an object file. It is generated from one or more source
files and may come from a library. The assembler generates a main scope for
symbols declared outside user generated scopes. The main scope has an empty name.
<itemize>
<item> Module id
<item> The name of the module including the path
<item> The id of the main source file (the one specified on the command line)
<item> The id of the library the module comes from, or CC65_INV_ID
<item> The id of the main scope for this module
</itemize>
<sect1>Scopes<p>
Each module has a main scope where all symbols live, that are specified outside
other scopes. Additional nested scopes may be specified in the sources. So scopes
have a one to many relation: Each scope (with the exception of the main scope) has
exactly one parent and may have several child scopes. Scopes may not cross modules.
<itemize>
<item> Scope id
<item> The name of the scope (may be empty)
<item> The type of the scope: Module, .SCOPE or .PROC, .STRUCT and .ENUM
<item> The size of the scope (the size of the span for the active segment)
<item> The id of the parent scope (CC65_INV_ID in case of the main scope)
<item> The id of the attached symbol for .PROC scopes
<item> The id of the module where the scope comes from
</itemize>
<sect1>Segment Info<p>
<itemize>
<item> Segment id
<item> The name of the segment
<item> The start address of the segment
<item> The size of the segment
<item> The name of the output file, this segment was written to (may be empty)
<item> The offset of the segment in the output file (only if name not empty)
<item> The bank number of the segment's memory area
</itemize>
It is also possible to retrieve the spans for sections (a section is the part of a
segment that comes from one module). Since the main scope covers a whole module, and
the main scope has spans assigned (if not empty), the spans for the main scope of a
module are also the spans for the sections in the segments.
<sect1>Source files<p>
Modules are generated from source files. Since some source files are used several times
when generating a list of modules (header files for example), the linker will merge
duplicates to reduce redundant information. Source files are considered identical if the
full name including the path is identical, and the size and time of last modification
matches. Please note that there may be still duplicates if files are accessed using
different paths.
<itemize>
<item> Source file id
<item> The name of the source file including the path
<item> The size of the file at the time when it was read
<item> The time of last modification at the time when the file was read
</itemize>
<sect1>Spans<p>
A span is a small part of a segment. It has a start address and a size. Spans are used
to record sizes of other objects. Line infos and scopes may have spans attached, so it
is possible to lookup which data was generated for these items.
<itemize>
<item> Span id
<item> The start address of the span. This is an absolute address
<item> The end address of the span. This is inclusive which means if start==end then => size==1
<item> The id of the segment were the span is located
<item> The type of the data in the span (optional, maybe NULL)
<item> The number of line infos available for this span
<item> The number of scope infos available for this span
</itemize>
The last two fields will save a call to cc65_line_byspan or cc65_scope_byspan by providing
information about the number of items that can be retrieved by these calls.
<sect1>Symbols<p>
<itemize>
<item> Symbol id
<item> The name of the symbol
<item> The type of the symbol, which may be label, equate or import
<item> The size of the symbol (size of attached code or data). Only for labels. Zero if unknown
<item> The value of the symbol. For an import, this is taken from the corresponding export
<item> The id of the corresponding export. Only valid for imports, CC65_INV_ID for other symbols
<item> The segment id if the symbol is segment based. For an import, taken from the export
<item> The id of the scope this symbols was defined in
<item> The id of the parent symbol. This is only set for cheap locals and CC65_INV_ID otherwise
</itemize>
Beware: Even for an import, the id of the corresponding export may be CC65_INV_ID.
This happens if the module with the export has no debug information. So make sure
that your application can handle it.
<sect1>Types<p>
A type is somewhat special. You cannot retrieve data about it in a similar way as with the other
items. Instead you have to call a special routine that parses the type data and returns it
in a set of data structures that can be processed by a C or C++ program.
The type information is language independent and doesn't encode things like 'const' or
'volatile'. Instead it defines a set of simple data types and a few ways to aggregate
them (arrays, structs and unions).
Type information is currently generated by the assembler for storage allocating commands
like .BYTE or .WORD. For example, the assembler code
<tscreen><verb>
foo: .byte $01, $02, $03
</verb></tscreen>
will assign the symbol foo a size of 3, but will also generate a span with a size of 3
bytes and a type ARRAY[3] OF BYTE.
Evaluating the type of a span allows a debugger to display the data in the same way as it
was defined in the assembler source.

<sect>Counter peripheral
<p>The sim65 simulator supports a memory-mapped counter peripheral that manages
a number of 64-bit counters that are continuously updated as the simulator is
running. For each counter, it also provides a 64 bit "latching" register.
<p>The functionality of the counter peripheral is accessible through 3 registers:
<itemize>
<item><tt>PERIPHERALS_COUNTER_LATCH</tt> ($FFC0, write-only)
<item><tt>PERIPHERALS_COUNTER_SELECT</tt> ($FFC1, read/write)
<item><tt>PERIPHERALS_COUNTER_VALUE</tt> ($FFC2..$FFC9, read-only)
</itemize>
<p>These three registers are used as follows.
<p>When a program explicitly requests a "counter latch" operation by writing any value
to the <tt>PERIPHERALS_COUNTER_LATCH</tt> address ($FFC0), all live registers are simultaneously
copied to the latch registers. They will keep their newly latched values until another latch
operation is requested.
<p>The <tt>PERIPHERALS_COUNTER_SELECT</tt> address ($FFC1) register holds an 8-bit value that
specifies which 64-bit latch register is currently readable through the <tt>PERIPHERALS_COUNTER_VALUE</tt>
address range. Six values are currently defined:
<itemize>
<item>$00: latched clock cycle counter selected.
<item>$01: latched CPU instruction counter selected.
<item>$02: latched IRQ interrupt counter selected.
<item>$03: latched NMI interrupt counter selected.
<item>$80: latched wallclock time (nanoseconds) selected.
<item>$81: latched wallclock time (split: seconds, nanoseconds) selected.
</itemize>
<p>Values $00 to $03 provide access to the latched (frozen) value of their respective live
counters at the time of the last write to <tt>PERIPHERALS_COUNTER_LATCH</tt>.
<p>When <tt>PERIPHERALS_COUNTER_SELECT</tt> equals $80, the <tt>PERIPHERALS_COUNTER_VALUE</tt>
will be a 64-bit value corresponding to the number of nanoseconds elapsed since the Unix epoch
(Midnight, Jan 1st, 1970 UTC), at the time of the last latch operation.
<p>When <tt>PERIPHERALS_COUNTER_SELECT</tt> equals $81, the high 32 bits of <tt>PERIPHERALS_COUNTER_VALUE</tt>
will be a 32-bit value corresponding to the number of seconds elapsed since the Unix epoch (Midnight, Jan 1st,
1970 UTC), at the time of the last latch operation. The low 32 bits of
<tt>PERIPHERALS_COUNTER_VALUE</tt> will hold the nanoseconds since the start of that second.
<p>The two different wallclock-time latch registers will always refer to precisely the same time instant.
For some applications, the single 64-bit value measured in nanoseconds will be more convenient, while
for other applications, the split 32/32 bits representation with separate second and nanosecond
values will be more convenient.
<p>Note that the time elapsed since the Unix epoch is an approximation, as the implementation depends on the
way POSIX defines time-since-the-epoch. Unfortunately, POSIX incorrectly assumes that all days are precisely
86400 seconds long, which is not true in case of leap seconds. The way this inconsistency is resolved is
system dependent.
<p>On reset, <tt>PERIPHERALS_COUNTER_SELECT</tt> is initialized to zero. If the <tt>PERIPHERALS_COUNTER_SELECT</tt>
register holds a value other than one of the six values described above, all <tt>PERIPHERALS_COUNTER_VALUE</tt>
bytes will read as zero.
<p>The <tt>PERIPHERALS_COUNTER_VALUE</tt> addresses ($FFC2..$FFC9) are used to read to currently
selected 64-bit latch register value. Address $FFC2 holds the least significant byte (LSB),
while address $FFC9 holds the most significant byte (MSB).
<p>On reset, all latch registers are reset to zero. Reading any of the <tt>PERIPHERALS_COUNTER_VALUE</tt>
bytes before the first write to <tt>PERIPHERALS_COUNTER_LATCH</tt> will yield zero.
Example:
<tscreen><verb>
/* This example uses the peripheral support in sim65.h */
#include <stdio.h>
#include <sim65.h>
static void print_current_counters(void)
{
peripherals.counter.latch = 0; /* latch values */

<sect>SIM65 control peripheral
<p>The sim65 simulator supports a memory-mapped peripheral that allows control
of the simulator behavior itself.
<p>The sim65 control peripheral interface consists of 2 registers:
<itemize>
<item><tt>PERIPHERALS_SIMCONTROL_CPUMODE</tt> ($FFCA, read/write)
<item><tt>PERIPHERALS_SIMCONTROL_TRACEMODE</tt> ($FFCB, read/write)
</itemize>
<p>Address <tt>PERIPHERALS_SIMCONTROL_CPUMODE</tt> allows access to the currently active CPU mode.
<p>Possible values are CPU_6502 (0), CPU_65C02 (1), and CPU_6502X (2). For specialized applications,
it may be useful to switch CPU models at runtime; this is supported by writing 0, 1, or 2 to this address.
Writing any other value will be ignored.
<p>Address <tt>PERIPHERALS_SIMCONTROL_TRACEMODE</tt> allows inspection and control of the currently active
CPU tracing mode.
<p>A value of 0 means tracing is disabled; a value of $7F fully enables tracing. The 7
lower bits of the value actually provide control over which fields are printed; see below
for an explanation of the seven fields.
<p>Having the ability to enable/disable tracing on the fly can be a useful debugging aid. For example,
it can be used to enable tracing for short fragments of code. Consider the following example:
<tscreen><verb>
/* This example uses the TRACE_ON and TRACE_OFF macros defined in sim65.h */
#include <stdio.h>
#include <sim65.h>
unsigned x;
int main(void)
{
TRACE_ON();
x = 0x1234; /* We want to see what happens here. */
TRACE_OFF();
return 0;
}
</verb></tscreen>
<p>This small test program, when compiled with optimizations enabled (-O), produces the output trace below:
<tscreen><verb>
70 232 022E A2 12 ldx #$12 A=7F X=00 Y=04 S=FD Flags=nvdizC SP=FFBC
71 234 0230 A9 34 lda #$34 A=7F X=12 Y=04 S=FD Flags=nvdizC SP=FFBC
72 236 0232 8D C8 02 sta $02C8 A=34 X=12 Y=04 S=FD Flags=nvdizC SP=FFBC
73 240 0235 8E C9 02 stx $02C9 A=34 X=12 Y=04 S=FD Flags=nvdizC SP=FFBC
74 244 0238 A9 00 lda #$00 A=34 X=12 Y=04 S=FD Flags=nvdizC SP=FFBC
75 246 023A 8D CB FF sta $FFCB A=00 X=12 Y=04 S=FD Flags=nvdiZC SP=FFBC
</verb></tscreen>
<p>The example output shows the full trace format, consisting of the following seven fields:
<itemize>
<item>The first field is an instruction counter. We see here that the assignment '<tt>x = 0x1234;</tt>'
starts at the 70th CPU instruction since the start of the simulator, and takes four 6502 instructions.
The two instructions that follow correspond to the execution of the <tt>TRACE_OFF</tt>' macro
that disables tracing.
<item>The second field shows the clock cycles since the start of the program. Here we see that the
first four instructions take 12 clock cycles in total (262 - 250 = 12).
<item>The third field shows the program counter as a four-digit, i.e., the PC register. Its 16-bit
value is displayed as a 4-digit hecadecimal number.
<item>The fourth field shows one to three hexadecimal byte values that make up the instruction.
<item>The fifth field shows the instruction in human-readable assembly language.
<item>The sixth field shows the CPU registers before execution of the instruction. The A, X, Y, and
S registers are each shown as a single byte value. The six status bits of the CPU are shown in
the order NVDIZC (Negative, Overflow, Decimal, Interrupt, Zero, Carry). They are displayed as
a capital letter if the flag is set, or a small letter if the flag is unset.
<item>The seventh and last field shows the software stack pointer SP as used by CC65 programs that
conform to the CC65 conventions.
</itemize>
<p>Writing a specific value to <tt>PERIPHERALS_SIMCONTROL_TRACEMODE</tt> will control which of these
seven fields are displayed. The following values are defined to denote the seven fields:
<itemize>
<item>TRACE_FIELD_INSTR_COUNTER = 0x40
<item>TRACE_FIELD_CLOCK_COUNTER = 0x20
<item>TRACE_FIELD_PC = 0x10
<item>TRACE_FIELD_INSTR_BYTES = 0x08
<item>TRACE_FIELD_INSTR_ASSEMBLY = 0x04
<item>TRACE_FIELD_CPU_REGISTERS = 0x02
<item>TRACE_FIELD_CC65_SP = 0x01
</itemize>
<p>For example, writing the value $16 to <tt>PERIPHERALS_SIMCONTROL_TRACEMODE</tt> will only display
the program counter, instruction assembly, and CPU registers fields.

/* The sim65 targets (sim6502, sim65c02) have a peripheral memory aperture located at
* address range 0xFFC0 .. 0xFFDF. Currently, the following peripherals are located
* inside that memory apeture:
*
* $FFC0 .. $FFC9 "counter" peripheral
* $FFCA .. $FFCB "sim65 control" peripheral
* $FFCC .. $FFDF (currently unused)
*
* The "peripherals" structure below corresponds to the register layout of the currently
* defined peripherals in this memory range. Combined with the fact that the sim6502 and
* sim65c02 linker configuration files define the "peripherals" symbol to be fixed at
* address $FFC0, this provides easy-to-use and efficient access to the peripheral registers.
*
* After including "sim65.h", it is possible for a C program to do things like:
*
* {
* peripherals.counter.latch = 0;
* peripherals.sim65.cpu_mode = SIM65_CPU_MODE_6502X;
* peripherals.sim65.trace_mode = SIM65_TRACE_MODE_ENABLE_FULL;
* }
*
* Note that "peripherals" variable is declared volatile. This instructs a C compiler to
* forego optimizations on memory accesses to the variable. However, CC65 currently ignores
* the volatile attribute. Fortunately, it is not smart with respect to optimizing
* memory accesses, so accessing the "peripherals" fields works fine in practice.
