[B2-devel] Remaining bugs

[Gwenole B. <gb...@di...>]

Hi,

Yet two important bugs to fix before looking at the JIT merge:

1) Apple Personal Diagnostics will crash once the main screen is drawn 
but prior to displaying any menu. It looks like trying to access 
something at 0x7fff7fff. I first though that was a FPU problem but it 
occurs with/without all 3 FPU cores in 68040 mode (tested with a patched 
main.cpp for FPUType).

In 68030 mode, I get the menu drawn but APD will crash some time after I 
move the cursor around. Probably an "off-by-one" error while popping 
from the stack. In the 030 case, one of the address to BlockMove was 
wrong (value was something 0x7fff0...).

I seem to be the sole guy having that problem. Even strangier, I think I 
already got the same problem long time ago, that got automagically fixed 
somehow then it's back broken for me nowadays. I will check the cpu 
cores.

2) B2/JIT will crash once FPU tests for Speedometer 3.23 are done. This 
does not occur with Speedometer 4.x, nor without JIT-FPU nor without JIT 
at all. So, it's bound to be a JIT-FPU specific bug.

BTW, any takers for the "scrollbar bug" when emulating m68k fpu 
registers with only double precision?

Bye,
Gwenole
