LLVM 20 on rawhide fails to build a function pgo optimized rust compiler on ppc64le. Enabling rust's LLVM IR Verification, LLVM produces an ICE similar to https://github.com/llvm/llvm-project/issues/138208. Likewise, rhbz#2367960 was also opened against this bug. I have locally backported and verified the fix for llvm#138208 also fixes the quiet failures observed while building the pgo-optimized rust toolchain and building rust-hyper-utils. Reproducible: Always Steps to Reproduce: 1. Enable PGO in rust package 1a. Optionally, enable rust.verify-llvm-ir to view the LLVM IR error. 2. Build on rust 3. Review logs for various test failures like segfaults or borrow errors.
