Subject: Re: Vector (and integer) API: unsigned min/max
Hi David,
It’s not at all outlandish, but would caution it's more work than one might
initially think.
Could you describe a little more about your use case? that can be helpful to
understand

I think that’s the path of least resistance. It’s just a vxor on each operand,
with a constant mask. That can be done in Java
Presently, I'm implementing operations for a WASM emulator/runtime, so it's
more a case of transitively acquiring use cases from WASM, though I'm also
doing this specifically to practice accomplishing useful things with the
vector API.
Regarding saturating arithmetic: WASM has operations for that
Hi David,

recommended approach with the
I've been trying the the incubating Vector API and one thing I've missed on
integer-typed vectors is having unsigned min/max operations. There is a
signed min/max operation, and unsigned comparison, but no unsigned min/max.
I guess this is for symmetry with `Math`, which only has signed
