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.
+

+<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.
+

+
+<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.

+ * Notes: For best results, the selected base address should

+ * select the region size as a power-of-two--if at all
+ * possible.

+ * A non-zero result is the first address at which an
+ * aliasing problem was uncovered. By examining the

+/*
+ * Sim65 cpu-mode switching example.
+ *
+ * Description
+ * -----------
+ *
+ * We can inspect and manipulate the CPU model that sim65 emulates at runtime.
+ *
+ * Sim65 always runs in one of three modes:
+ *
+ * - 6502 mode: the 151 documented opcodes are supported; if the processor encounters
+ * one of the 105 undocumented opcodes, the simulator ends with an
+ * 'illegal opcode' message.
+ * - 65C02 mode: the 105 undocumented opcodes now have well-defined behavior. Some
+ * do useful things, while all others are now defined as NOPs.
+ * - 6502X mode: the 105 undocumented opcodes don't have documented behavior, but
+ * they /do/ have behavior on a real 6502. This behavior has been
+ * figured out, and is deterministic (with minor exceptions).
+ * In this mode, sim65 mimics the behavior of a real 6502 when
+ * it encounters an undocumented opcode, rather than terminating.
+ *
+ * In the example below, we first switch to 6502X mode and execute a small
+ * assembly code fragment, then repeat this in 65C02 mode.
+ *
+ * The code fragment is designed to distinguish between a 6502 and a 65C02
+ * processor based on the behavior of the ADC function in decimal mode.
+ *
+ * Important Note:
+ *
+ * When running in a program compiled for the "sim6502" target, it is safe to switch to
+ * 65C02 or 6502X mode, since the runtime library will only use plain 6502 opcodes, and
+ * those work the same in 65C02 and 6502X mode.
+ *
+ * However, when running in a program compiled for the "sim65c02" target, it is NOT safe
+ * to switch to 6502 or 6502X mode, since many routines in the runtime library use
+ * 65C02-specific opcodes, and these will not work as expected when the CPU is switched
+ * to 6502 or 6502X mode. When such an instruction is encountered, the program will
+ * exhibit undefined behavior.
+ *
+ * For this reason, this program will only work when compiled for the "sim6502" target.
+ *
+ * Running the example

+ * Sim65 timer example.
+ *
+ * Description
+ * -----------
+ *
+ * This example tests the clock cycle counter feature of sim65.
+ *
+ * The function 'timestamp' obtains the lower 32-bits of the clock cycle counter.
+ *
+ * The function 'calc_sum_terms' calculates the sum of a range of integers
+ * starting at zero. It simply iterates over all terms, which means that its
+ * runtime is a linear function of its input value.
+ *
+ * In the main function, we first derive an 'offset' value by getting two timestamp
+ * values, with nothing happening in between. Ideally this should yield a 0 clock
+ * cycle duration, but due to the overhead of calling the 'timestamp' function,
+ * and the 'timestamp' function itself, the difference between these timestamp
+ * will be non-zero. We store this value in the 'overhead' variable, and subtract
+ * this value in later measurements.
+ *
+ * Next, we measure the duration of calling the function 'calc_sum_terms' with two
+ * input values, 0, and 1. The duration includes storing the result in the 'result'
+ * variable.
+ *
+ * Extrapolating from these two measurements, and assuming that the runtime of
+ * calling 'calc_sum_terms' and storing its result scales linearly with its argument,
+ * we can predict the duration of a call to 'calc_sum_terms' with a much larger
+ * argument (max_terms = 10000).
+ *
+ * Finally, we actually measure the duration with max_terms = 10000. If the
+ * duration measured is equal to the predicted value, we exit successfully. If not,
+ * we exit with failure.
