Lots of bugs in 32-bit x86 Linux entry code

I remember being an early adopter of 64-bit Linux with my Athlon64 back in the day. Lots of stuff was broken and I got a lot of debate on whether it was any faster or worthwhile at all. It's really cool to see the technology curve go full circle.

Maybe because nobody uses 32-bit x86 anymore?

No, that's the i386 architecture, which is still well supported AFAICT. x86_32 is a funny architecture that requires 64 bit chips but uses 32 bit pointers.

There were 32-bit netbooks being sold the last time I looked in 2015.

Jesus was closer to dinosaur times than we are to 2015.

No, that’s “x32”. “x86_32” is not an official name for anything, but based on the contents of the post, I believe Andy Lutomirski is using it to refer to 32-bit x86, aka i386.

Are you Him?

Your comment should be the top comment. I had no clue i386 and x86_32 where different. I though the article was saying 32bit linux is broken.... but no some strange "alternative" mode on linux is broken.... who cares.
