FPU 80-bit accuracy

Post by msteel » Fri 15 Jun, 2018 12:18 pm

Hey guys,

I’m not sure if this can be used in PCem but looking at WinUAE emulator for the Amiga, just implemented full 80-bit FPU support. http://www.winuae.net

Source code can be found here https://github.com/tonioni/WinUAE?files=1

Thanks.

Only on x86 - non-x86 platforms have to use softfloat. Since PCem also runs on ARM (as of a couple of days ago), portability isn't an academic question anymore and an x86-only solution isn't viable.
