basiliskii: request 64-bit build

[rickyzhang82 (Ricky Zhang)]

This request comes form a discussion thread: ​https://www.emaculation.com/forum/viewtopic.php?f=6&t=9737&p=59966#p59966

There is no reason to build BasiliskII in 32 bit for latest Intel Mac. Because next gen Mac OS X may forbid 32 bit app to run.

Please allow the build in 64 bit. At least make it as default variant or a fat binary.

Thanks.

Hi Ricky. Last time I checked, lots of things didn't work quite right with the 64bit build, and there didn't seem to be any advantage to 64b over 32b, ergo the 32b default. IIRC, the issues were networking, full-screen graphics glitches, and the JIT.

But I'm happy to take another look.

I think there will be big pressure to get these all fully fixed once MacOS no longer supports 32bit -- that will be within the couple of years, I understand, but not any time right soon.

I totally agree with you. It is still early to worry about deprecation of 32bit app from Apple.

In my box, I always build in 64bit. Because I don't need networking or JIT. But I didn't experience full screen glitches in SDL1 as you suggest.

Perhaps, we should port QEMU slirp 64 bit clean first.

For JIT, I really don't think it is necessary for modern beefy Intel CPU. Emulation 68K is a piece of cake.

When I was first working on this port, I had a 64 bit build enabled with no JIT and no slirp (networking). I can make that available again.

[rickyzhang82 (Ricky Zhang)]

Can we do it as a variant? In this way, we don't break what is already there.

If you are interested in make slirp 64 bit clean, we can do that in Github.
