January 10, 2016 [dmd-internals] Future of DMD on OS X 32bit? | ||||
---|---|---|---|---|
| ||||
What are the general thoughts on the support for 32bit on OS X? Do we need to continue support it or can it be dropped? I know that we agreed that the Objective-C support should only be implemented for 64bit.
I have implemented native TLS for DMD on OS X 64bit. Does it need to work on 32bit as well? If not, should it use the existing emulated TLS or can we drop it completely?

Posted in reply to Jacob Carlborg | Asking on the ng is a good idea. I'm a bit concerned about iOS. My understanding is iOS is a pared-down OSX/32, is that right? If that's the case, if we choose to neglect/drop OSX/32, we're creating difficulties for ourselves later. I just saw http://arstechnica.com/apple/2015/07/the-state-of-the-64-bit-transition-in-ios-and-whats-left-to-be-done/, so apparently we're at the tail end of iOS/32?

Apple stopped selling 32-bit iOS devices in 2015. There is still a lot of 32-bit devices out there that are still supported by the newest OS, including my 2011 iPad 2. Developers can ship 64-bit only apps today if they want, the App Store allows that. ... and then came the Apple Watch which is 32-bit and runs watchOS, a pared-down down iOS. -- Michel Fortin https://michelf.ca _______________________________________________ dmd-internals mailing list dmd-internals@puremagic.com http://lists.puremagic.com/mailman/listinfo/dmd-internals |

I don’t think it’s a big issue. Would it be ok to continue use emulated TLS for 32bit? Otherwise I think there's just some minor issue with the instructions generated to access a TLS variable. Perhaps someone that actually knows how DMD works could help out. -- /Jacob Carlborg _______________________________________________ dmd-internals mailing list dmd-internals@puremagic.com http://lists.puremagic.com/mailman/listinfo/dmd-internals |
