[hatari-devel] WinUAE Falcon emulation and FPU

[Eero Tamminen <oak@xxxxxxxxxxxxxx>]

Hi,

I noticed that "Flu" demo:
http://www.pouet.net/prod.php?which=17796

Crashes with WinUAE to line-F exception.

It works fine with old UAE core.


The reason seems to be that WinUAE core defaults
FPU to "none".  If I select any other FPU option,
the demo works fine.

Does old UAE core 030 setting emulate FPU?


As Falcon has 68030 which doesn't include FPU and
Falcon didn't include a separate FPU, how this demo
can work on real Falcon?

Or is the problem exception handling?

(It seems unlikely that a 4k demo would have
separate code for running with and without
FPU though.)
