I thought it might be good to centralise the TODO list for Zilsd support, so we can collaborate across orgs a little better.
Here are some possible improvements relating to Zilsd:
- [ ] Spills/Reloads (https://github.com/llvm/llvm-project/pull/153595)
- [ ] Callee-Saves?
- [ ] Allocation Priority of GPRPairs?
Craig remarked there's an interaction of Zilsd with Zfinx/Zdinx which we may need to resolve/improve. I don't have the details fully in my head.
NXP's tree with Zilsd support is here: https://github.com/nxp-auto-tools/llvm-project/tree/Zilsd/release/18.1.6 - but much of these changes have been reimplemented from scratch upstream already.
