what makes armv7 32 bit supportable?

[Nintonito]

Question just popped in my head today about the arm JIT. How come dolphin can still support 32 bit arm processors but not 32 bit x86 processors? Is it a matter of maintainance, or is just the arm architecture handling certain things better?

There weren't any arm64 chips for android until recently and development had to start from somewhere. It was either arm 32 or nothing, hope that answers your question.

the main issue with supporting 32bit x86 is with the x86 JIT.
In Linux you can still build a 32bit x86 binary, it'll just not have a JIT to run with.

32-bit ARM doesn't completely suck like 32-bit x86 - it turns out having only 6 GPRs is a major limitation, who would have guessed!
