Just a note for everyone here who doesn't follow blfs-book : With llvm added in /opt/llvm and at the front of my PATH (test: clang --version reports 10.0.0) I'm again seeing a failure from rust issue 69225 https://github.com/rust-lang/rust/issues/69225 which is why I was building 1.41.1 with its shipped llvm rather than old system llvm-9.0.1 (as documented in the wiki for firefox and rust). Failing the test added in 1.41.1 for that problem makes me think _my_ build is not safe to use. I know that Pierre only had 4 failures, but accidentally deleted the log (yeah, I too have done that often enough) so I don't know for certain if something in my rustc-1.42.0 build was fubar'd, but for the moment I'm not going to procede with measuring 1.42.0 until I can try to get a handle on this. My build used all 8 cores and my own CFLAGS, CXXFLAGS so not relevant to the SBU and space figures for the book. ĸen -- When alle is ſayed and all is done, ye must chooſe your faces wisely, for soon enouff ye will be playing with fyre."
