I think that it mess around with .globl or :: directives to define a global symbol into GPU sections.
.68000 nop lea m68k_foo,a0 nop .long m68k_foo: dc.l 0 m68k_bar: dc.l 0 .GPU .org $f03000 nop movei #gpu_foo,r0 nop .long gpu_foo: dc.l 0 Output: swapd0$ rmac -fe test.s -o out.elf swapd0$ nm out.elf 00f0300c a gpu_foo 00000010 t m68k_bar 0000000c t m68k_fooNow m68k_foo and gpu_foo are defined as global(:
.68000 nop lea m68k_foo,a0 nop .long m68k_foo:: dc.l 0 m68k_bar: dc.l 0 .GPU .org $f03000 nop movei #gpu_foo,r0 nop .long gpu_foo:: dc.l 0 Output swapd0$ rmac -fe test.s -o out.elf swapd0$ nm out.elf U gpu_foo 00000010 t m68k_bar 0000000c T m68k_foo swapd0$Last code using old version of rmac:

I've compiled the just game (not the library) with the old version of rmac, and this is the output of nm with the gpu.o:

It's not easy to write a small example, here it's what I have.
- C/Asm library where I got some references to a GPU symbols that it's not compiled with the library, all GPU code files are copied into the include directory.
- The game includes the library code
- I have a gpu.s file like this:
.include "jaguar/jaguar.inc" _gpu_code_start:: .gpu .org G_RAM movei #G_ENDRAM,r31 moveta r31,r31 .include "katu/gpu_event.s" .include "katu/gpu_sprite.s"This way I can include more files with gpu code specific to that game. These two files must be included, and gpu_event.s must be first.
The game complies with no problem but I have linker errors for all symbols defined in gpu_event.s and gpu_sprite.s that are referenced from the library.
edit: I've tried with .globl directive or with -u option but it have the same error, undefined reference.

working on it.

by the way I'm using gcc linker, not rln but it worked with the older version of rmac.

24 minutes ago, ggn said:Also, I do appreciate the obscene language, makes it feel worth the trouble
Sorry
24 minutes ago, ggn said:Repro case please, and we'll look into it. What is the problematic symbol's name?
The symbol name are _gpu_events_list, _GPU_SPRITE_OFFSET_X, _GPU_SPRITE_OFFSET_Y, and a few more, by the way the symbols are defined into a GPU chunk but referenced from 68000 code.
I've also seen that I can't create a label name like "x" or "y" (it was a register equate), anyway I've changed them to cx or cy. No problem.
-
It looks that there are more changes, for example I've in a source file a label defined with two colons at the end, so it's supposed that the label it's global, this label it's referenced from a second file and I've an .extern directive at the beginning but I get a linker error of an undefined reference even if I put a .globl label in the first file.

411 case 'I': 412 { 413 searchpath = argv[argno] + 2; 414 415 // Check to see if include paths actually exist 416 if (strlen(searchpath) > 0) 417 { 418 DIR * test = opendir(searchpath); 419 420 if (test == NULL) 421 { 422 printf("Invalid include path: %s\n", searchpath); 423 errcnt++; 424 return errcnt; 425 } 426 427 closedir(test); 428 } 429 430 break; 431 }
Yes, I've just seen it... f*ck because they have changed the way it works, but there's a function called nthpath that looks for ';' to get multiple paths from a single argument.

6 minutes ago, 42bs said:You might either repeat "-i" or use ":" (guess)
Nope, I'm looking at rmac code and you can use -I option only one time, I've also tried with ':' but the code looks for a ";"
6 minutes ago, 42bs said:Or use " around your path.
Ok, but now I've "invalid include path" error, and I've tested that both path exists... weird, I'll run rmac with the debugger.

After some days off (maybe two weeks?), I've updated rmac to 2.0.12 and now I get an error when I try to compile my projects, I've this definition in the makefile:
RMAC = rmac -fe -i/opt/local/bin/gcc68k/include;/Users/Shared/apps/Jaguar/projects/libWhen I call make I get

(What became of your website @swapd0?)
As an aside, I'm also personally curious what happened to the JagCF project and the Catnip. I keep coming across mentions of them (Stumbled upon
this the other day), and other mentions that the projects didn't come to fruition, but no real explanation as to why.
Yeah, that was long time ago...
Try to get a skunk board, it saves a lot of headaches and the upload speed it's a lot faster.

But with BJL you are restricted to 2MB of RAM, you can't use the ROM space as "mass-storage".

I'm a bit busy now and not I'm sure how to upload a patch and if I can do it, anyway I've changed the following, tested and work with huge files.
File token.c line 25 -> uint16_t curlineno; -> uint32_t curlineno;
File token.h line 157 -> uint16_t curlineno; -> uint32_t curlineno;

I'm using U235-SE 0.24 and works flawlessly.

2 hours ago, ggn said:This is weird because there has never been v1.13.6: version went from 1.13.5 to 2.0.0 ;). But I reverted to roughly that point in the repository and built rmac - sure enough it is perceived as legit code. You are encouraged to update to the latest version here as we fixed this and added a bunch more fun stuff like the ability to assemble a binary without header at a fixed address (-fr)!
Maybe I changed the version from 1.13.5 to 1.13.6 because a few months ago I had to compile it and change the line number from short to int because I was checking a disassembled file and I got errors with weird line number.

23 hours ago, LinkoVitch said:If you want to check functionality of 68K and be able to step through it to make sure it's doing what you expect I highly recommend Easy68K.. it's a full featured 68000 simulator, and you can step through instructions, monitor memory etc. Really handy.
I assume you are building up a SE command, would it not be faster to combine the values with or and only write to memory once (well 2x 16bit words) rather than a bunch of individual 8 bit writes.Nope, I'm not building a SE command, that comes a bit later in the code, but it's executed each time that I play a new sounds.
Maybe I'm using an older version of rmac, mine it's 1.13.6.

I'm using rmac.

IMHO they never tried to code a real game while the hardware was in development, because you'll find a lot of bottlenecks and fixing them could improve a lot the machine.
You can't make an After Burner (sprite + scaling + rotation) without a lot of headaches, and it's a game from 1987...

I've the following code in my sound engine, it's using u253se. The d0 has a sound channel (4 to 7) and d1 holds a sample number. It always hangs.
; register sound move.b d1,channel_sound(pc,d0.w) move.b d0,sound_channel(pc,d1.w)Even this version hangs, WTF!?!?!
; register sound moveq #0,d0 moveq #0,d1 move.b d1,channel_sound(pc,d0.w) move.b d0,sound_channel(pc,d1.w)As you can see I'm writing bytes so there are no problems about alignment, anyway I've a .long directive before channel_sound definition.
But, I've done a quick test with this code and it works...
; register sound moveq #0,d0 moveq #0,d1 move.w d1,channel_sound(pc,d0.w) ; move.b d0,sound_channel(pc,d1.w)There are any problem with byte memory access from the 68000? I don't understand why it hangs, if I comment the code it works.
-
68000 it's too slow for a 32/64 bit machine. Maybe a Motorola 88000 could be nice instead of the other RISC.
A better solution, remove the 68000, DSP & GPU and put three existing RISC (all the same of course), one for the main logic, IO, AI, etc, other for graphics and the last one for the sound system. The time saved could be used to fix some blitter bugs and improve the performance.

There's a typo in the docs. The value should be 10010010 = $92, isn't it?
Voice Status Register (U235SE_voice_status) Represents the current sample processing status of each voice. If a voice is currently processing a sample (even if that sample is silence), then its corresponding bit will be set. If the voice is idle and has no sample to play then the bit will be clear. For example, if there were samples playing on voices 1,4 and 7 only, then the voice status register would be $4a (binary 01001010 – remember voices start at 0)-

IMO even with a better hardware it would fail but at least the oficial game library could be 10 times bigger.

You are right, in my case I've the jaguar on the right side of the computer that's the reason that I would prefer the upper position and I'm in the 1% (actually 0.1%?) of the people that will use it.
Anyway it's a great product.

The only thing that I don't like is that the USB port is on the right side of the cart, IMHO it's better if is placed on the upper side.

Done and it compiles the game, but I haven't tested it.
