fijal: I meant, is there a substantial difference in maturity, or features, or or any noteworthy limitations? (also, I asked the question unaware of the recent blog post, and I'm more curious about armv7)
<alcarithemad>
the blog post is good, though, and answers my question

_aegis_: OK, and if it were cffi's fault I'd hide behind "it's actually libffi's fault, not something we can easily fix within cffi"
<arigato>
that would have been my reaction 5 years ago, but indeed nowadays libffi is more stable

alcarithemad: the aarch64 backend is missing the C float type, which makes working with C floats slower (C doubles are fine). Apart from that there might possibly be still one or two very-rare bugs because it's not really field-tested yet. But pypy's JIT backends tend to work fine once they work at all---haven't had any real problem with the ppc64 and the s390x backends for example
