I still perfer No. 3. There is a PR for LLVM-9 in rust repo: https://patch-diff.githubusercontent.com/raw/rust-lang/rust/pull/62474.patch -- Xi Ruoyao <xry...@mengyan1223.wang> School of Aerospace Science and Technology, Xidian University -- http://lists.linuxfromscratch.org/listinfo/blfs-dev FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
