Correction A7 is the R2 OG SoC, the last 32-bit only ARM! If you have one hold on to it... I knew it was special! They are removing 32-bit from modern ARM...

They are removing 32-bit from modern ARM... but Intel will always have 32-bit!
- sounds 3y agoIntel makes it sound like they will never drop their legacy support, and are just "testing the waters" with X86-S, but internally the discussion is over. https://news.ycombinator.com/item?id=36013257 https://news.ycombinator.com/item?id=36013257
- bullen 3y agoIf anyone could give me a good answer to why 64-bit is useful I wouldn't argue. But now I'm planning a 64-bit linux ARM distro that only runs 32-bit apps!
- sounds 3y agoI'm reading between the lines a bit to try to answer, so if I missed your question or your intent please just point it out and I will adjust my answer. 32-bit is extremely useful. For intel, 16-bit is also very useful. The problem is that there is a strong divide between the people who find 32-bit and 16-bit useful at Intel, and the people who feel a need to force everyone onto UEFI "Class 3+" [1] and that everything else must be squeezed out, shamed, and moved to an emulator. It sounds like Arm 32-bit support might be around for a while. I mainly wanted to clarify that Intel is dropping their 32-bit and 16-bit support.

- taffronaut 3y ago32-bit Arm is not being removed. There's the modern 32-bit only Cortex-A32 "AArch32 for full backward compatibility with Arm v7" [1]. Also expect 32-bit code compatibility to exist for a long time on Arm embedded cores for code size reasons.

- bullen 3y agoIt's being removed from the leading architectures. Which is a very bold, and probably bad move.
