Thanks guys, I still haven't managed to get the breakpoints working, grr! Roman, can you remember when we did we have breakpoints working? If we did, then that will give me a base to compare to.

The helloworld example doesn't crash for me but the breakpoints don't work. For example

#include <stdio.h>

int main (void)
{
  
printf ("hello worldn");

  return 
0;
}


Runs without crashing but any breakpoints just get ignored.

I've uploaded some updates which that to deal with the debug messages sent by our hook function. For instance,

#include <stdio.h>

int main (void)
{
  
int *i_p NULL;

  
printf ("here comes the crash...n");

  
/* BOOM! */
  
*i_p 9;

  return 
0;
}


will now get caught by gdb, though you can't inspect the variables, etc. yet. So that needs adding too. Hopefully the code from https://github.com/alfkil/Spotless/blo ... r/SimpleDebug/Symbols.cpp will give that to us.

If you look at lines 96-109 of amigaos-nat.c, there are two new flags to adjust which functions get used by our target

/*
 * If this is TRUE, then the breakpoint code based upon Spotless
 * is used. If this is FALSE, then the breakpoint code based upon
 * the old gdb 6.3 port is used instead.
 */
static const BOOL s_use_spotless_breakpoints_flag FALSE;

/*
 * If this is TRUE, then the memory transfer routine from the old
 * gdb 6.3 port is used. If this is FALSE, then the code uses the
 * new partial_mem_transfer API with amigaos_xfer_partial ()
 * instead.
 */
static const BOOL s_use_deprecated_mem_transfer_flag TRUE;


So still more to do but hopefully the breakpoints will work soon!

As far as I can tell, we never have a working breakpoint in our version, we only now reach the point when we start to make it works.

I downloaded now your latest commit at this moment, and rebuild it all from scratch, and tested it on x5000 firstly - still crashes.

Then tried it on pegasos2. There I didn't have a crash, but after I set breakpoint and hit "run", it then didn't stop on a breakpoint and didn't give me the ability to type things in the terminal (i.e. it didn't finish the executing now as well)

As far as I can see when comparing serial logs from x5000 and pegasos2, x5000 do not like the "amigaos_xfer_memory()" function. It can be that it has an issue, just a crash didn't happen on other than x5000 machines by some luck (maybe that issue indirectly can have impact on non-working breakpoint code?)

Havent time to works on breakpoint stuff ? Maybe have some issues in process which worth to discuss so to progress futher ?

Hi Roman, yeah it's been a bit slow in the last few days but I'm hoping to pick it up again in the next week. Obviously if anyone wants to get involved too, then they're very welcome!

I've been going through the Spotless code too so see how things are done there which hopefully will give some insight into what I'm not doing for the breakpoints to be picked up correctly in GDB.

Sorry for being away from this for a few weeks, work has been crazy, I'll be back on this in thex next few days. As another route into this, I've also been working on getting a version of Alfkil's SimpleDebug code, since it worked for me, ported from C++ to C as a way of getting another debugger working too. One of the lessons I got from our work on GDB is that it helps me actually understand what is going on codewise more easily doing it that way, rather than tinkering at the edges of existing code not necessarily understanding what is going on. This should help the GDB port too and of course I'll make the github repo public. I also plan to add things like a gui to it too.

Cool, I was in fear you give up :)

As for another debugger that also good, but we surely need GDB, because we only need "to port" things which already done.

Do you mean to GDB? Yeah, that will be more or less easy, as it well documented how to make GUIs for GDB, and some of GUIs even already present in (i compile SDL2 fronted based on ncureses, and it works, through with lots of bugs).

What we need now is tracing to work, and it will be already usable.

I plan to learn to use and then heavily (ab)use it, once it's done.

Thank you for not giving up on GDB.

I look forward to it getting (ab)used! Well I still haven't managed to get the breakpoints working yet, something odd is going on. I've used both the old gdb trap instruction and the code that SimpleDebug uses and even though it appears that the breakpoint instructions get written to the memory, the code just happily executes. I've confirmed that the SimpleDebug breakpoint codes in itself so it's a bit of a puzzle. The next thing to check is the memory address that is getting overwritten with the breakpoint to see if it's the same for both programs.

On the plus side, the work I've done on adapting SimpleDebug means that we're still closer to having at least one debugger. My plan is still to get gdb behaving properly too but it's good to have options.

I guess for breakpoint to work they have to be in memory and not in the processor caches, so caches must be off when setting the breakpoint right?

That's a good point, I call

IExec->CacheClearE((APTR)address0xffffffffCACRF_ClearICACRF_ClearD);


after setting them. It's the same code in both SimpleDebug and gdb, but only works in SimpleDebug at the moment. My next step is to check a few bytes either side of where I'm putting the breakpoint to check whether they are the same in both situations in case I'm somehow writing to the wrong address in gdb.

You could maybe try with ClearCacheU and see if it works.

Thanks for taking my code seriously. It is definetely of paedagogical interest if not otherwise. It is also meant as a gift. If I had a machine, I would continue the work myself, but sadly I don't. Good to see the wheels running in here.

I'm not really into the whole stuff, but having reading the whole thread, and it seems that you are stuck with the problem that your set breakpoints doesn't trigger, i give here my two cents about it. It might be completely wrong are right or something in between, but i hope it it can be taken as brain storm input and you get something from it.

Anyway, might it be that you except for installing the breakpoint, which is a "trap" instruction you even need to install some kind of interrupt handling routine? Because during google trap instruction on ppc, i found that the execution of a trap instruction raises a program interrupt.

I have no clue how to do it on the Amiga side. I tried to look into the db101 code, to see if there is any code underlining my assumption. But it is way out of my scope. Furthermore i would guess that the kernel has a default interrupt routine for that case, which just does nothing. And thus nothing happens when the code executes your breakpoint.

There is an issue on timing related to the setting and clearing of breakpoints. What kasie and billyfish is trying to do is to clear the instruction cache and is hoping, that this will establish a safety point to rely uppon, when execution of the sub-process is re-initiated. Only problem is : We have not established this. Unless we know how to rely and/or not rely on a function like IMMU->CacheClearE(), we have no grounds for assuming, that it works in one way or another.

In my initial work with db101 (and Qt as well), I needed to constantly check the minutest details about how the different functions of the system expressed their reliability-matrices. This resulted in a rather large battery of test-apps - all written in c - that might still reside on some harddrive somewhere. This is of course not an attempt to elicit some kind of awe-inflicting "historical value"-argument on my old harddrives. It is rather to say, that if you guys want to make progress, you need to isolate problems, and you need to go small - very small. I'd say, unless you can create a test-application in less than 5 lines for the main() function, and unless you can make that test app absolutely certainty-locked-hammered-and-closure-proven show, that your case is clear as a polished winter morning in your favorite fairytale fantasy - then you still have work to do.

Keep going, I know you can fix this.

Btw, you might want to work on this one, instead of having a ReAction frontend in the way :

Are you saying that you don't have any OS4 hardware? If so, it shouldn't be like that. Someone should fix it.
