wasmtime / issue #9882 Target 32bit architecture (now tha... · git-wasmtime

Now that we have Pulley, we're keen to get wasmtime working on 32 bit Windows. My assumption here is that this is in roadmap?

Today, if you build wasmtime and target i686-pc-windows-msvc or i686-pc-windows-gnu, the compiler complains. I'm assuming that the fix should be relatively minimal but I'm not familiar with wasmtime internals.

cargo run  --target=i686-pc-windows-gnu
