  • wasm-mutate stuff, lots of "good first issue" type stuff if people want to contribute!
• Alexa VanHattum:
  • Been looking into verifying ISLE
  • iadds that compile down into subs
  • SAIL(sp?) seems easier to work with in aarch64 than x86-64, probably starting there

  • Looking into ISLE
• Anton Kirilov
  • Finished an initial pointer auth impl in aarch64 backend

  • Issues with A vs B keys and unwinder
  • Current pauth prototype doesn't use nop-space instructions
  • Need to figure out how this integrates with Wasmtime's fibers
    • Apple ABI docs suggest that you can just find the return pointer and frame pointer as long as you don't keep arbitrary code pointers in registers
• Johnnie Birch
  • Doing a little benchmarking work
  • Triaging and cleaning up old issues, could use some help from anyone who has time
• Benjamin Bouvier
  • No updates
