FYI this patch saves ~3% instructions for some benchmarks from LLVM-test-suite on RISC-V. https://github.com/dtcxzyw/llvm-ci/issues/1115 https://github.com/dtcxzyw/llvm-ci/issues/1114 https://github.com/llvm/llvm-project/pull/82404 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
