[issue33125] Windows 10 ARM64 platform support
Steven Noonan <ste...@uplinklabs.net> added the comment: I originally tagged this issue against 3.6 just because that's what I was attempting to build. But I'm not super concerned about what release these changes actually land in, I can always backport it to my own builds (and at my own risk). Even though I'm super interested in seeing these changes done, I'm not sure I'm the right person to do the heavy lifting on this. I don't know if the seemingly undocumented (?) Windows ARM64 ABI matches the well-documented Linux AArch64 ABI, for example. If it does match, that would make porting the asm bits pretty straightforward (mostly just translating GNU assembler AT syntax to MASM, I suppose). I could do that. But if it doesn't match then I'd probably need to dig into ARM architecture manuals. Someone else could likely do it in their sleep. -- ___ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue33125> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue33125] Windows 10 ARM64 platform support
Steven Noonan <ste...@uplinklabs.net> added the comment: Oh, another change I had to make was remove all the BaseAddress elements in the Link sections. The linker complains if these are used (the lower 4GB of memory are apparently reserved for the x86 emulation). Also, from what I was told by someone over at Microsoft, the BaseAddress options don't do anything useful on modern Windows versions unless you build with -fixed as well, because everything gets relocated anyway. -- ___ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue33125> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue33125] Windows 10 ARM64 platform support
New submission from Steven Noonan <ste...@uplinklabs.net>: The Windows 10 ARM64 release is out along with a bunch of ARM64 devices. This version of Windows has full support for building native Win32 applications (this isn't just some rehash of Windows RT). It also can run x86 (but not x86_64) apps under a transparent emulation layer. I would like to see a native build of Python on Windows 10 ARM64. I did some very basic work to get it compiling (add 10.0.16299.0 as DefaultWindowsSDKVersion, add WindowsSDKDesktopARM64Support property). But there's still a lot missing: ssl, tk, and ctypes don't build. ssl/ctypes have some assembly that needs writing/porting. tk has some kind of build failure with the newer Windows SDK: https://core.tcl.tk/tk/tktview?name=3d34589aa0 -- components: Windows messages: 314295 nosy: Steven Noonan, paul.moore, steve.dower, tim.golden, zach.ware priority: normal severity: normal status: open title: Windows 10 ARM64 platform support type: enhancement versions: Python 3.6 ___ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue33125> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
