Since LLVM 15 pointers are not typed. Using the latest inkwell surfaces this as a warning. The fix is just to replace the ptr types with env.context.ptr_type(AddressSpace::default()) as advised by cargo check.

After making this change, there were a number of places where variables were no longer used, so I followed chippy's suggestions and removed each of these.

- // warning: use of deprecated method `inkwell::types::FunctionType::<'ctx>::ptr_type`: - // Starting from version 15.0, LLVM doesn't differentiate between pointer types. - // Use Context::ptr_type instead.

I don't fully understand this change. I believe LLVM optimisation no longer occurs at a function level and so the function_pass manager is no longer required. Here I have removed this, but we still keep the verification check.

Request this be looked at this more closely.

The LLVM MajorMinor is actually 181, but most references still want 180 so we hardcode it here.

-            "c",


This was causing issues with zig build-obj when exporting main. We had an error saying duplicate symbol.

I believe the cause of this is that now zig 0.13.0 bundles wasi-libc, and so if we include -lc we now have two main functions, one from wasi-libc for the WASI implementation because we build the host at -target wasm32-wasi and also from out host.zig.

@Anton-4 -- not urgent, just making a note while I'm looking at this

We need to update the following in CI workflows to use zig 13.

      - name: Update PATH to use zig 11
        run: |
          echo "PATH=/home/big-ci-user/Downloads/zig-linux-x86_64-0.11.0:$PATH" >> $GITHUB_ENV

I also think we should start using ROC_ZIG environment variable somehow, I don't see it in any of the CI scripts. Could we make this change against our current main, or would this be better in this PR?

New PR on main sounds good!

This reverts commit 530cffa.

We should merge #6859 first before this PR.

Failure on nix x64 linux is the same as here: #6859 (comment)
