Looks great thank you, ready to go I think really just a couple of minor clarifications + double check we want to merge the breaking change

I can't track where this change comes from?

This is from changing the JIT tests to call raw function pointers - that path is somewhat pickier about integer width than the old ExecutionEngine::run_function approach. Previously we were calling exec_hugr_u64 on things that didn't return i64 and it just happened to work. Added a note about this in the description

is this reflecting a bug in the original test?

I think so - log width 2 would be an i4 but LLVM has no such type?

Build times for `--workspace --all-features` went from >2mins to over 30mins after we merged #2901. It affected not only `hugr-llvm` every crate, but every dependant too; | Unit | Total | Features | -- | -- | -- | hugr-cli v0.25.7 describe "test" (test) | 1265.1s | default, tracing | hugr-cli v0.25.7 validate "test" (test) | 1261.7s | default, tracing | hugr-cli v0.25.7 hugr "bin" | 1260.8s | default, tracing | hugr-cli v0.25.7 convert "test" (test) | 1253.3s | default, tracing | hugr-core v0.25.7 hugr_core "lib" (test) | 633.8s | declarative, default, serde_yaml, zstd | hugr-core v0.25.7 model "test" (test) | 607.4s | declarative, default, serde_yaml, zstd We are tracking down this issue, but in the meantime this PR removes the `hugr-llvm` feature from the stable required checks, so we can continue doing development without waiting hours to merge stuff. Here is a `cargo test --timings` example: [cargo-timing.html](https://github.com/user-attachments/files/25884694/cargo-timing.html) I made a couple drive-byes to help with the still slow cases: drive-by: Remove unneeded transitive `aws-lc-sys` dependency, that was slow to compile. drive-by: Fix `rs-semver-checks`. #2901 updated it in an incorrect way drive-by: Add a concurrency limit to the rust checks workflow, so pushing new changes to a PR stops existing runs. --------- Co-authored-by: Alec Edgington <[email protected]>

BREAKING CHANGE: The hugr-llvm LLVM version is being upgraded to 21.1, and code that depends on it here needs to be updated as well. This also includes an MSRV change to 1.91 to match hugr. See [the hugr PR](Quantinuum/hugr#2901) for details. Closes #1421 --------- Co-authored-by: Jake Arkinstall <[email protected]> Co-authored-by: Agustín Borgna <[email protected]>

BREAKING CHANGE: This PR upgrades the Inkwell LLVM version flag to
llvm21-1fromllvm14-0(tested with LLVM version 21.1.8). The primary breakage between these versions is the removal of typed pointers from LLVM IR. It also updates the hugr MSRV to 1.91 to avoid mysterious errors when linking the new llvm_sys with older toolchains.Details
CallableValuetrait was removed from Inkwell. Invocations of function pointers are now constructed using a separatebuild_indirect_callmethod which takes the function signature as a separate argument.StaticArrayCodegen::static_array_typereturns the type "pointer to static_array<T>"). These pointers no longer carry type information, but are still used to determine the size in memory of a reference to these types. When type information is needed we acquire it elsewhere.TypingSessioncurrently maps HUGR function types to function pointers. After the upgrade, it now maps all function types to the opaque pointer type. This is unintuitive, but seems to work currently, because the output of the type mapping is only used to determine size in memory of a reference to function types (so the pointer type is correct). If this changes in future, we may need to introduce separate APIs to query the "storage type" and "underlying type" of a function.ExecutionEngine::run_function. The same IR returns the correct value if called using a raw function pointer returned byExecutionEngine::get_function. For that reason, I have changedTestContext::exec_hugrto use the raw pointer method for all JITed tests. This also requires being more specific (and accurate) about the return types of some JITed test functions.Tip for reviewers
Closes #2886
