If we take this and then run it through the LTO pass things go wrong. ```console > ld.lld --lto-emit-llvm start.o -r --lto-partitions=8 -plugin-opt=O3 > --lto-CGO3 -o test.o ``` This either results in some definitions being missing or a corrupted LLVM-IR file so it's non-deterministic. ```console > opt -S test.o opt: test.o: error: can't skip to bit 50048 from 42112 ``` Can I revert this? https://github.com/llvm/llvm-project/pull/128509 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
