The runtime thing is the easy part. I was wondering about the stack probes, which require LLVM support. There's a comment in the sources that suggest it's still x86-only, but that may be outdated: “ //! Finally it's worth noting that at the time of this writing LLVM only has //! support for stack probes on x86 and x86_64. There's no support for stack //! probes on any other architecture like ARM or PowerPC64. LLVM I'm sure would //! be more than welcome to accept such a change! ” https://github.com/rust-lang/compiler-builtins/blob/master/src/probestack.rs https://github.com/rust-lang/compiler-builtins/blob/master/s...
