JIT FPU Bug ?   Message List  
Reply | Forward Message #176 of 313 |
Hallo All!

I am new in this group and maybe this is already known,
so forgive me if it is like this.

I found out that the FPU Emu behaves a bit strange,
on Amithlon as well as under WinUAE.
I did not manage yet too really isolate the problem but
it occures like this:

I make some FPU calculations. After that I convert them into
longintegers. Normaly this is no problem. But when the JIT
becomes active - lets say you start a new shell or call a function
of a programm you havent called before - something
goes wrong and the longwords contain some wired stuff.
Maybe already the FPU registers are trashed before.

Normally it should never influence a running task if another task is
doing something, as therefore whe have context switches.
But in this case it is obviously another task
influencing, as everything goes fine if you keep hands off starting
other programms. So my conclusion is that this must be a bug in
the FPU emulation.

Any ideas ?

Ciao,

Thilo
