This also happened today, and not only with LLD but also with BFD, so "due to different handling of `--wrap` compared to GNU ld" seems wrong. Unfortunately, I couldn't create a minimal reproducer, so I can't tell whether the issue lies in the linkers, libc++, or libcygwin.a. Other functionalities look good to me; this patch enables bootstrapping using LLD without hacky linker flags. https://github.com/llvm/llvm-project/pull/147960 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
