+Normally when a breakpoint is triggered, emulation is stopped and you
+get to the debugger. Breakpoint options can be used to affect what
+happens when a breakpoint is triggered. These options are given after
+the conditions and are prefixed with ':'.
+
+Note: you can give multiple options for conditional breakpoints, but
+for address breakpoints you can give only one these options. And
+"file" option is supported only for conditional breakpoints.
+
+"b help" explains very briefly the breakpoint condition syntax:
+
+For CPU breakpoints, mode is the address width; it can be byte ("b"),
+word ("w") or long ("l", default). For DSP breakpoints, mode specifies
+the address space: "P", "X" or "Y". Note that on DSP only R0-R7
+registers can be used for memory addressing. For example;
+
If the value is in parenthesis like in '($ff820)' or '(a0)', then the
used value will be read from the memory address pointed by it. Note
-that this value is checked at run-time whereas quoted expressions
-(mentioned above, please read!) are evaluated already when adding a
-breakpoint. For example, to break when value in adress pointed by A0
-matches the value currently in D0, one would use:
+that this conditional breakpoint expression value is checked at
+run-time whereas quoted arithmetic expressions (mentioned in
+Entering arguments
+to debugger commands above) are evaluated already when
+adding a breakpoint. For example, to break when a value in an address
+(later) pointed by A0 matches the value currently in D0, one
+would use:
+If you're interested only on certain bits in the value, you can use
+'&' and a numeric mask on either side of comparison operator to
+mask the coresponding value, like this:
+
-M68k addresses can have byte ("b"), word ("w") or long ("l", default)
-width. DSP addresses belong to different address spaces: "P", "X" or
-"Y". Note that on DSP only R0-R7 registers can be used for memory
-addressing.
+Comparison operators should be familiar and obvious, except for '!'
+which indicates inequality ("is not") comparison. For example:
Examples:
+As a convenience, if the both sides of the comparison are exactly the
+same (i.e. condition is redundant as it's always either true or
+false), the right side of the comparison is replaced with
+its current value. This way you can give something like this:
+ As:
-The debugger supports also setting conditional breakpoints on values
-of some internal Hatari variables (listed by "b help"). For example
-if you want to stop at a specific cycle within a frame (that is, PC
-relative to the current VBL/HBL in cycles), set breakpoints to
-specific "HBL" and "LineCycles" variable values. The "e" command
-can be used to calculate suitable register and variable values.
+That in itself isn't so useful, but for inequality ('!') comparison,
+conditional breakpoint will additionally track and output all further
+changes for the given address/register expression. This can be used
+for example to find out all value changes in a given memory address,
+like this:
+Because tracking breakpoint conditions will print the evaluated
+value when it changes, they're typically used with the trace option
+to track changes e.g. to some IO register.

-There are also several options that you can use with both breakpoint
-types. ":trace" option will make breakpoint to print out the tracked

+Hint: "info" command "aes", "bios", "gemdos", "vdi" and "xbios"
+subcommands for can be used to list the corresponding OS-call opcodes.
+For example, to see the GEMDOS opcodes, use:
+As the file pointed by the breakpoint ":file" option (see
+Breakpoint options) can contain any
+debugger commands, it can also be used to do automatic "chaining" of
+debugger and breakpoint actions so that after one breakpoint is hit,
+another one is set.
For example if you have these input files:
-":once" option that removes breakpoint after hit can be useful when one
-wants to get out of a loop (when at the instruction that branches back
-to loop start) or just to get to a specific point in code:
+And then start Hatari with the first debugger input file and a GEMDOS
+harddisk directory containing "desktop.inf" file:
-Whereas giving count (like ":2") as option will break only on every
-<count> hit.
+Note: because debugger input files cannot "continue"
+emulation, ":trace" option needs to be used for the breakpoint(s)
+if you want emulation to continue after the breakpoint action(s).
-After analyzing and/or setting new breakpoints, you can continue the
-emulation with the "c" command. You can continue for a given number of
-CPU instructions (or DSP instructions when "dc" is used), or you can
-continue forever (until a breakpoint triggers) if you omit the
-instruction count.
+Hint: It's better to test each input file separate before testing the
+whole chain. Besides the ":file" breakpoint option, these debugger
+input files can be also read with the debugger "file" command, "lock"
+command "file" option and with the Hatari "--parse" command line
+option.
+After analyzing the emulation state and/or setting new breakpoints,
+you can continue the emulation with the "c" command. You can continue
+for a given number of CPU instructions (or DSP instructions when "dc"
+is used), or you can continue forever (until a non-tracing breakpoint
+triggers) if you omit the instruction count.
+
+If you want to continue just to the next instruction, use "s" (step)
+command to continue for exactly one instruction, or "n" (next), if you
+want to skip subroutine calls.
+
-If you want to continue with real-time disassembling, you can enable it
-with "trace cpu_disasm" at the debugger prompt before continuing.

+Profiling tells where the emulated code spends most of its (emulated)
+time. It can be used to find out where a program is (apparently)
+stuck, or what are the largest performance bottlenecks for a program.
+
+Profiling is used by first enabling the profiler (use "dp" for DSP):
+
+And profiling will start once you continue the emulation:
+
+When you get back to the debugger, the collected profiling information
+is processed and a summary of in which parts of memory the execution
+happened, and how long it took, is shown:
+
+(DSP RAM will be shown only as single area in profile information.)
+
+When you're back in debugger, you can inspect the collected profile data:
+ For example, to see which memory addresses were executed most
+and what instructions those have at the end of profiling, use:
+Then, to see what the executed code and its costs look like
+around top addresses:
+
+Unlike normal disassembly, "profile addresses" command shows only
+memory addresses which instructions were executed during profiling.
+You get instruction cache misses only when using cycle-accurate 030
+emulation with a Hatari version configured to use WinUAE CPU core.
+
+If you have loaded symbol information, symbol names are shown above
+the corresponding addresses. With the "profile symbols" command you
+get a list of how many times the code execution passed through the
+defined symbol addresses.
+ Profile data accuracy depends on Hatari emulation accuracy.
+Profile data accuracy from most to least accurate when Hatari's
+default emulation options are used is following:
+If you have loaded symbols (see Debug symbols)
+before continuing emulation/profiling, additional caller information
+will be collected for all the code symbol addresses which are called
+as subroutines. This information includes callstack, call counts,
+calling instruction type (subroutine call, branch, return etc), and
+costs for those calls, both including costs for further subroutine
+calls and without them.
+ When debugger is re-entered, current callstack is output before
+profiling information: ("profile stack" command can be used in breakpoints with :noinit
+option to show backtraces during caller profiling.) Other information collected during profiling is shown with
+following command:
+For example, if you don't know all the places from which a certain
+function is called, or in what context a certain interrupt handler can
+be called during the period you're profiling, profile caller
+information will tell you:
+
+(Most "calls" to "dsp_interrupt" were subroutine call returns (=r)
+to it from address 0x155.)
+
+With the execution counts in normal profiling data, caller information
+can actually be used to have complete picture of what exactly the code
+did during profiling. Main/overview work for this analysis is best done
+automatically, by the profiler data post-processor (documented below).
+ Everything about profile data accuracy applies also to caller costs,
+but there are additional things to take into account, mainly because
+profiler cannot determine when exceptions are being handling: It's useful to save the profile data to a file:
+ With the saved profile disassembly (and optional caller information)
+you can more easily investigate what your program did during
+profiling, search symbols & addresses in it, and compare the
+results to profiles you've saved from earlier versions of your code. You may even create your own post-processing tools for
+investigating the profiling data more closely, e.g. to
+find
+CPU/DSP communication bottlenecks. Saved profile data can be post-processed with (Python) script
+installed by Hatari, to: When the data is post-processed, you should always provide
+the post-processor symbols for the profile code! Relying just on the
+symbol in the profile data can cause costs to be asssigned to wrong
+symbol, if symbol's code wasn't called through symbol's own address,
+but by jumping inside its code. If your code is in fixed location, you should tell
+post-processor to handle symbol addresses as absolute (-a): Normal programs are relocated and you should instead give
+the symbols as TEXT (code) section relative ones (-r): If symbols are included to your binary in DRI/GST format, first they
+need to be extracted to the ASCII format
+understood by the post-processor: If there are some extra symbols that you don't want to see
+separately in profiles, because they aren't real functions,
+but e.g. loop labels, you can either remove them manually
+from the ASCII *.sym file, or filter them out with grep:
+ Above post-processor examples just parse + verify the given data
+and produce output like this: To get statistics (-s) and list of top (-t) CPU users in profile,
+add "-st" option: If you want to see also symbol addresses and what is per call
+cost, add -i option:
+ (For cycles the "per call" information is in seconds, not as
+a cost count.) If your profile file contains caller information, you should
+add -p option to see it, as that will also help in detecting symbol
+issues (see Interpreting
+the numbers):
+ Now there's a message telling that some of the calls were ignored as
+based on "call type" they were determined to be actually returns from
+exceptions, not real calls (this is mainly important for callgraph
+generation, discussed below). In addition to accuracy issues mentioned in previous Profiling
+sections, function/symbol level costs have gotchas of their own. The first cost percentage and count columns are sums for all
+the instructions that were in profile data file between
+the indicated symbol's address and the address of the next symbol
+(= "between-symbols" cost). NOTE: If your symbol file doesn't contain addresses
+for all the relevant symbols, results from this can be misleading because
+instructions costs get assigned to whatever symbol's address
+happened to preceed those instructions. And you don't see which
+caller is causing it from caller info or callgraph either, as entry
+point for that time sink lacking a symbol means profiler hadn't
+tracked calls to it... The next two cost percentage and count columns are for subroutine
+calls costs, first one for exclusive and latter for inclusive cost
+i.e. including costs for further subroutine calls. Values are based on
+caller information documented above. Reasons why between-symbol costs, and subroutine call costs can
+differ are following: In the first case, you should check the profile data to find out
+whether there are missing symbols for executed function entry points.
+You can notice function entry points as address gap and/or code
+retrieving arguments from stack, and exit points from RTS instruction. Second case can also be seen from the profile data. Call count
+is same as count for how many times first instruction is executed
+(worst case: large loop on subroutine's first instruction). While subroutine costs should be more accurate and relevant, due to
+code optimizations many of the functions are not called as subroutines
+(on m68k, using JSR/BSR), but just jumped or branced to. Because of
+this, it's useful to compare both subroutine and between-symbols
+costs. One should be able to see from the profile disassembly which
+of the above cases is cause for the discrepancy in the values. NOTE: Before starting to do any serious source
+level optimizations, you should always verify from profile
+data (disassembly) where exactly the costs are in a function, to make
+sure your optimization efforts can actually help the performance. Callgraphs require saved profile data to contain caller information,
+i.e. symbols should have been loaded before starting profiling (normally
+done with "symbols prg" command in Hatari debugger). Separate callgraphs will be created for each of the costs
+(0=calls, 1=instructions, 2=cycles) with the -g option: Callgraphs are saved in GraphViz
+"dot" format. Dot files can be viewed: Produced callgraph will look like this: Interpreting the callgraph: If profile is for larger and more varied amount of code
+(e.g. program startup), the resulting callgraph can be so
+huge it's unreadable. If your code has interrupt handlers, they can get called
+at any point, which can show in callgraph as "explicit" calls
+from the interrupted functions. To get rid of such incorrect
+calls, give interrupt handler names to --ignore-to option: In large callgraph most of the functions aren't really interesting,
+because their contribution to the cost is insignificant. You can
+remove large number of them with --no-leafs and --no-intermediate
+options, they act only on on nodes which costs are below
+given threshold. Leaf nodes are ones which don't have any parents
+and/or children and intermediate ones which have only single parent
+and children (node calling itself is not taken into account).
+
+ Threshold for this is given with the --limit (-l) option. With
+that it typically makes also sense to change the node emphasis
+threshold with --emph-limit (-e) option: If you're not interested in from how many different addresses
+a given function calls another function, use --compact option. If you
+still see multiple calls between two nodes with it, the reason is that
+they happened through different call paths which were removed from
+the callgraph after --compact option was applied: If even this doesn't help, you can remove all nodes below
+the given cost threshold limit with --no-limited option, but this
+often doesn't leave much of a call hiararchy. Instead you may
+consider removing all nodes except for subroutine call ones with
+--only-subroutines option. If you have trouble locating nodes you're specially interested
+about, you can either color them differently with the --mark option,
+or exclude everything else from the callgraph except those nodes and
+their immediate callers & callees, with the --only option: Last option for reading the callgraph is using -k option to
+export the data for use in (Linux) Kcachegrind UI. It generates
+callgraphs on the fly, and just for the area around the function
+you selected, so navigating in callgraph may be easier. It also
+shows the related profile disassembly, which can make verifying
+matters easier:
+Here's a list of some common debugging tasks and how to do them
+with the Hatari debugger:

+Breakpoint condition notes
+
+
+
+
+
+
+For breakpoints that track just a single IO register memory address, or
+multiple ones of which none are modified by Hatari,
+only by emulated code, this is not a problem, they get triggered as
+expected.
+
+However, if you have a breakpoint that tracks multiple IO registers
+where some of them are updated by Hatari, for example to check that
+other Blitter registers aren't updated while control register
+indicates Blitter to be active (busy), things don't work as expected!
+Breakpoint variables
+
+b pc = TEXT :once
+
+Note1: It's better to trigger it only once because if you'd leave it on,
+during reboot you would get a warning for every instruction until TOS sets
+a valid basepage.
+
+Note2: you cannot use an address breakpoint for this because value of
+a variable given to address breakpoint is evaluated when it's set, not
+at run-time, so it cannot get the new value that the TEXT variable
+gets when you start a program.

+'profile' - profile CPU code
+Usage: profile <on|off|stats|counts|cycles|misses|symbols|callers|stack|addresses|save> [count|address|file]
+ 'on' & 'off' enable and disable profiling. Data is collected
+ until debugger is entered again at which point you get profiling
+ statistics ('stats') summary.
+
+ Then you can ask for list of the PC addresses, sorted either by
+ execution 'counts', used 'cycles' or cache 'misses'. First can
+ be limited just to named addresses with 'symbols'. Optional
+ count will limit how many items will be shown.
+
+ 'addresses' lists the profiled addresses in order, with the
+ instructions (currently) residing at them. By default this
+ starts from the first executed instruction, or you can
+ specify the starting address.
+
+ 'callers' shows (raw) caller information for addresses which
+ had symbol(s) associated with them. 'stack' shows the currect
+ profile stack, this is useful only with :noinit breakpoints.
+
+ Profile information can be saved with 'save'.
