* this requires upgrading to wasmparser 0.67.0. * There are no CLIF side changes because the CLIF `select` instruction is polymorphic enough. * on aarch64, there is unfortunately no conditional-move (csel) instruction on vectors. This patch adds a synthetic instruction `VecCSel` which *does* behave like that. At emit time, this is emitted as an if-then-else diamond (4 insns). * aarch64 implementation is otherwise straightforwards.
This crate performs the translation from a wasm module in binary format to the in-memory form of the Cranelift IR.
