## Not yet supported

|
||||
* Inline assembly ([no cranelift support](https://github.com/bytecodealliance/wasmtime/issues/1041))
|
||||
* On UNIX there is support for invoking an external assembler for `global_asm!` and `asm!`.
|
||||
* SIMD ([tracked here](https://github.com/rust-lang/rustc_codegen_cranelift/issues/171), `std::simd` fully works, `std::arch` is partially supported)
|
||||
* Unwinding on panics ([no cranelift support](https://github.com/bytecodealliance/wasmtime/issues/1677), `-Cpanic=abort` is enabled by default)
