  • Can the Rust compiler be compiled to WASM and run on a browser?

    Part of rustc bas been compiled to wasm previously. A hello-world program has ran via rustc/miri on wasi. A benefit of adding a wasm backend to cranelift would allow for the cranelift backend for rustc compile code inside and to run in the browser.

    wasmtime[0] is a WebAssembly standalone runtime that does JIT. It’s quite performant anecdotally and I think some benchmarks might be available.

    Ish. You should be able to bundle something with https://github.com/bytecodealliance/wasmtime which will be as near as damnit

    But ...

    "Cranelift does not yet perform mitigations for Specter or related security issues, though it may do so in the future." (https://github.com/bytecodealliance/wasmtime/tree/main/crane...)

    Will the wasmer runtime handle specter / meltdown / rowhammer attacks?

    If that's the case, try a runtime like Wasmer, wasmtime, WAVM, or SSVM.

  • Cranelift, Part 3: Correctness in Register Allocation
    reddit.com/r/rust | 2021-03-15
    In a little more detail -- we handle register saves/restores in the ABI implementation which explicitly reasons about caller/callee-saves. The interaction with regalloc is actually kind of elegant IMHO: we just add all of the caller-save registers as defs on the call instruction. Regalloc.rs allows real (physical) registers alongside virtual registers in the VCode, and will see these defs and move other data out of the way.
    reddit.com/r/rust | 2021-03-15
    In fact, I just double-checked and it seems we've already wired the regalloc bit of this up for Wasmtime here, and for any other Cranelift user that exposes the settings; on Wasmtime, -s regalloc=backtracking_checked should in theory give exactly this.

    Very interesting article! Uses Spidermonkey Cranelift already for IonMonkey or only for Webassembly? I am refering to (https://github.com/bytecodealliance/wasmtime/blob/main/cranelift/spidermonkey.md#phase-2-ionmonkey)[the documentation]

    reddit.com/r/rust | 2021-03-10
    Great to see more progress on this! It would also be neat for cranelift to add a webassembly backend, which would allow a rustc compiled to wasm to produce wasm modules using cg_clif.
  • Is there a way to build a plugin system for rust code with dynamic libraries ?
    reddit.com/r/rust | 2021-03-04
    The list of languages that support wasm is growing, and Rust support is already excellent. With Wasmer and wasmtime you have two excellent Rust-native wasm engine options with multiple backends.

  • Interview with Ryan Dahl, Node.js & Deno creator
    The other improvements that are usually talked about are the sandboxing feature and the module system. The sandboxing feature is possibly interesting if you're writing scripts that will run on other people's machines, but for most web development it basically offers nothing that existing containerisation technologies don't already provide, just that the containerisation options are usually easier to configure in one central place. It would be more useful if it could do things that containerisation couldn't — WASM is a good example here, where the WASI interface uses "capabilities" to ensure that external modules can only open things that they are explicitly given access to (see [1]). I'm not entirely sure whether this sort of thing is possibly in such an enthusiastically dynamic language as JavaScript, but I think Deno would have been a more useful and interesting project if it had explored in this direction.
