Yeah, you are right, it also says in Docs/Readme.txt file:

Quote:
WinUAE 1.2
==========

New features:

- FPU emulation updates and fixes.
Not sure what is the benefit of new JIT-FPU (1.2) version ... are there some test cases that said it is better than older one (1.1.1) ?!

Otherwise, how about temporarily to have both versions of JIT-FPU engines implemented into WinUAE that could be selected f.ex. with a check box ?!


p.s. Other approach could be maybe to compare a source code from both versions to see what was changed ... ?!

I am not good in Amiga machine programming, but perhaps could be possible to test JIT-FPU opcodes in WinUAE using/writing some assembler program that will check does the JIT-FPU engine instructions return right values ?! Or maybe a such program already exist, dont know so cant tell ?!
