The bint instruction returns 0 or 1. The bmask instruction returns all zeros or all ones. #3205 is about the actual representation in registers and memory, not about the result of bint/bmask, right?

I didn't realize bint was also a vector instruction. I'm up for clarifying the docs and implementing it for vectors or just restricting vectors from this instruction.

https://github.com/bytecodealliance/wasmtime/issues/3205 is about the actual representation in registers and memory, not about the result of bint/bmask, right?

That is my understanding of it as well.

Also, as a side note, could this PR close https://github.com/bytecodealliance/wasmtime/issues/2237? Or is that issue already effectively done?

No, that issue I think is mostly related to the trampoline generating the wrong code when loading / storing booleans, and its why I had to do duplicate some code in this PR in order to not have boolean arguments to the test cases.

I think restricting vectors from this instruction is the easiest path for now.

Yes, primarily it is about representations, but @cfallin mentions bint in the description and I bring up an all ones/all zeroes comment ater. The main reason for me mentioning it here is that I want GitHub to keep track of all the cross-links between related issues (and semi-related issues, in this case) so that it is easier to investigate later.
