Please support arm64

Hi! We'd love to use this library, but we're currently all in on arm64. Is there a chance you'll do an arm64 version of this port?

That is a significant effort @lizthegrey - we are open to pull requests.
Ah, I see, it's not a mechanical translation, it's a hand port? Will take that under consideration. Thanks!
There is arm64 support in the original simdjson project -- so it is definitely possible to port this over, but it will be a significant effort.
A more manageable (and possibly also more useful) would be Go fallback. That would probably also make porting easier.
Stage 2 only uses SIMD for string parsing, so that should be rather trivial, but obviously stage 1 is a bit more involved. Though I don't understand enough of it to do it.
I would also like to get rid of the remaining allocs, but I currently don't have the bandwidth for it.
That said, with the latest clean up it looks like a decent v1.
Go fallback would be useful indeed.
I needed a workaround for arm64 machines for simple things like running small tests and debugging, so I hacked together https://github.com/kiwicom/fakesimdjson . By the way, the tape is exported from the simdjson package, is the tape format considered part of the stable API?
Would simdjson-go project consider something like fakesimdjson useful enough to be included or are you interested only in more direct implementations of stages 1 and 2? Obviously something like my hack can't be used to guide ports to new architectures.
@martin-sucha Not guaranteed, which is why we are still at v0.x
. We have no plans to change it, but only API and the serialized format can be considered stable.
You are welcome to send your repo code as a PR, if it makes sense to add.
the original simdjson has some support of the arm64 https://github.com/simdjson/simdjson/tree/master/src/arm64
