build log of systemd-246.6
Here is the build log of systemd-246.6, just in case it is needed.
Looks specific to the combination of clang + ld.lld + -flto (clang+ld.lld works without lto, and gcc+ld.bfd works either way). I'd advise against using those C(XX)FLAGS and LDFLAGS, especially on a global scope (e.g. use something more normal like "-march=native -O2"). clang/lld support is already not very tested, exotic flags isn't going to help. You are right. After I switch off lto, everything works perfectly fine. This makes me wonder whether this is a compiler bug in clang. Please work with upstream if you want this toolchain config to be supported. |
