This seems to be caused by either an LLVM or Rust bug that is encountered when compiling a massive number of doctests in parallel on i686: error: ran out of registers during register allocation LLVM ERROR: Cannot emit physreg copy instruction Couldn't compile the test. I would call that an LLVM bug first, unless we find something specific that Rust is doing wrong. Do you know if there's a way to limit parallelism for building doctests? It seems like rustdoc does not limit the number of compile tasks it launches in parallel at all, which might contribute to this issue. The parallelism should default to the number of logical cpus, but you can set RUST_TEST_THREADS=1 (or any number). This bug appears to have been reported against 'rawhide' during the Fedora 35 development cycle. Changing version to 35. Ok ... I ran a scratch build with RUST_TEST_THREADS=1, and the i686 issue is still the same: https://koji.fedoraproject.org/koji/taskinfo?taskID=73671680 ---- src/build/arg_group.rs - build::arg_group::ArgGroup::arg (line 119) stdout ---- error: ran out of registers during register allocation LLVM ERROR: Cannot emit physreg copy instruction Couldn't compile the test. Not sure how LLVM would ever run out of registers during code generation ... FEDORA-2021-d30f9d81fe has been pushed to the Fedora 36 stable repository.
