If you only need something to test against locally, I was able to get our s390x rust dist built against your patches https://github.com/rust-lang-ci/rust/actions/runs/13668570835. `rust-std-s390x-unknown-linux-gnu/lib/rustlib/s390x-unknown-linux-gnu/lib/libcompiler_builtins-77321e818a95f60c.rlib` has all six conversion symbols, though I haven't been able to test their correctness on the platform. https://github.com/llvm/llvm-project/pull/109164 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
